1. Key policy insights

Thailand has achieved remarkable economic and social development since the 1960s. Among countries in Southeast Asia, Thailand was one of the first to open its economy by pursuing an active integration into global value chains (GVCs) and attracting foreign direct investment (FDI), which enabled the country to undertake significant investment in infrastructure. Thailand’s manufacturing sector was able to gain a competitive edge, while the tourism industry also flourished with increasing facilities for large-scale tourism. In the context of this continuous growth, Thailand became an upper-middle income country in 2011, following the classification used by the World Bank.

However, Thailand’s growth has been losing momentum over the last decade. GDP per capita has stagnated at the same time as other countries in the region experienced more vigorous growth (Figure 1.1). In response, several policy initiatives have been launched to boost productivity, including by focusing on high value-added industries.

The already softer growth momentum was further weakened by the economic fallout from the pandemic. More recently, Thailand’s economy was also heavily affected by rising energy and food prices in the context of Russia’s war of aggression against Ukraine, which triggered a cost-of-living crisis and caused a delay in structural reforms. As the effects of both the pandemic and high energy prices are gradually receding, Thailand will now need to address a number of key structural challenges, including population ageing, the digital transition, possible reconfigurations of global value chains and the green transition. In fact, Thailand is faced with one of the most rapid processes of population aging in Southeast Asia, with the old-age dependency ratio more than doubling over the past two decades (Figure 1.2).

Further policy efforts to raise productivity will be key to rekindle and eventually accelerate the convergence process towards higher income levels. This will include continuing to attract foreign investment, which has been an engine of growth in the past. Stronger efforts to improve the business climate and foster competition will be key for this, including by relaxing remaining restrictions to foreign direct investment, especially in the particularly restrictive services sector, and expanding trade agreements.

Against this background, the 13th National Economic and Social Development Plan for 2023-2027 aims to boost the transition towards a higher value-added and more sustainable economy. The 13th plan is embedded in the 20-Year National Strategic Plan 2018-2037, which is the first long-term strategy at the national level, guided by the objective to obtain high-income status by 2037.

Recent developments have also pointed to the need for Thailand to construct a more comprehensive social safety net to support the most vulnerable parts of the population. Income inequality has significantly improved since the 1990s, as evidenced by a substantial decline in the Gini coefficient from 0.44 in 1990 to 0.38 in 2021. Nonetheless, further efforts will be required to achieve more inclusive growth, as more than 50% of workers in Thailand are in the informal sector and remain outside the reach of the formal social security system.

Against this backdrop, the main messages of this Economic Survey are:

  • Macroeconomic policies will need to strike a careful balance between supporting the still on-going recovery and containing inflation pressures. Monetary policy should maintain its current stance and remain vigilant to inflation pressures. Fiscal policy should support these efforts and revert to a firm consolidation path. Emergency support to households should be phased out, while protecting those most in need with regular social protection instruments.

  • Structural reforms will need to continue. Regulatory reform will be key to reduce market entry barriers and boost competition. Efforts to prevent and fight corruption should be continued. Labour market and social policies will have to be stepped up to enhance social inclusion, while bringing down high labour informality and strengthening social safety nets for the unemployed and the elderly.

  • Achieving current net zero emission pledges will require bold policy action. A comprehensive strategy for carbon pricing in combination with tighter regulations will need to be applied swiftly to frontload the green transition, while phasing out other government interventions in energy prices. Stronger incentives will be needed for both domestic and foreign investment in higher energy efficiency, renewables and green innovation.

The Thai economy has seen a substantially later and weaker recovery from the pandemic than other Southeast Asian countries, amid a protracted rebound in tourism and continuously high uncertainties around the global economic outlook, on which the economy is highly dependent. Annual growth returned to 2.6% in 2022, up from 1.5% in 2021, but this remains moderate in a regional comparison (Figure 1.3, Panels A and B).

Along with a steady rebound of private consumption and investment, exports increased rapidly in 2022, largely owing to the return of foreign visitors as Thailand lifted pandemic-related travel restrictions in September 2022. The number of foreign tourists rebounded to 11 million in 2022, up from only 0.4 million in 2021 (Figure 1.3, Panel F). Merchandise exports continued to decline in early 2023, but at a slower pace than before. The current account deficit has widened amid higher energy prices.

After having surged to 7.9% in August 2022, inflation has come down to -0.3%, below the target range. Domestic financial conditions have tightened as the Bank of Thailand raised its policy rate to 2.5% in September 2023, marking the eighth consecutive increase since August 2022 when the rate was at 0.5%. The monetary tightening successfully brought down inflation, albeit in combination with a temporary tax reduction on diesel fuel. The progressive pass-through of tighter financial conditions to households and corporates continues to weigh on domestic demand, compounding an already-high debt service burden of households and corporates.

In late 2022, the economy experienced a soft patch due to weaker external demand. Quarterly real GDP contracted by 1.1% in the last quarter 2022 in seasonally-adjusted terms relative to the previous quarter, as export of goods declined (Figure 1.3, Panel D), reflecting subdued global demand amid tighter global financial conditions. This soft patch reversed in the first quarter of 2023 with positive GDP growth of 1.7% relative to the previous quarter, after accounting for seasonal influences, followed by weaker growth of 0.2% and 0.8% in the second and third quarters of 2023, respectively. In year-on-year terms, the economy has now been growing at a pace of 2.7%.

Manufacturing activity suffered from renewed declines in new orders in early 2023. Retail sales, by contrast, rebounded visibly in early 2023, as steady declines in inflation support household spending. Recovering domestic demand is also visible in rising merchandise imports in early 2023, and both business and consumer confidence indices have improved recently (Figure 1.3, Panel C).

The recovery has also been visible in the labour market, especially since the resumption of economic reopening in early 2021. In early 2023, the unemployment rate returned to 1.1%, the same rate as in 2019. At the same time, around 8% of the labour force work less than 24 hours a week (less than 20 hours per week for agricultural workers).

The labour market has shown remarkable resilience over the past few years, especially when compared with regional peers and the OECD average. Even at the peak of the pandemic, employment declined only modestly, and the recovery has been strong (Figure 1.4, Panel A). During the COVID-19 crisis and subsequent recovery, women fared better than men in terms of employment. Among women, employment has risen by 8% since 2019Q4, compared with 4% for men. The overall robust employment was associated with a stable labour force participation, unlike in other countries where many people left the labour force during the pandemic (Figure 1.4, Panel B). The unemployment rate remained low and stable throughout the pandemic period, with a small increase of 0.7 percentage points from late 2019 to early 2021, from 0.7% to 1.4%.

This labour market stability has partly been attributed to Thailand’s diverse industrial structure (OECD, 2020[1]), a feature that often goes along with less volatility (WTO, 2021[2]), (Brown and Greenbaum, 2017[3]), (Carvalho, 2014[4]). In 2020 and 2021, the export-oriented electronics sector benefited from the pandemic-induced upsurge of external demand, followed by a gradual rebound in inbound tourism that started in 2022. In addition, there are also structural factors that can explain Thailand’s persistently low levels of unemployment (Box 1.1). During 2021, for example, increases in the number of self-employed workers, especially those who worked in agriculture, offset decreases in other forms of employment, notably dependent workers, with some reversal in 2022 (Figure 1.5).

Going forward, the Thai economy is projected to continue its gradual recovery. Real GDP is expected to grow by 2.7% in 2023 and to strengthen to 3.6% in 2024 and 3.2% in 2025 (Table 1.1). Private consumption is projected to remain strong, although the gradual phase-out of government relief measures and high levels of household debt will weigh on the purchasing power of households. Business investment will be vigorous as the economy rebounds and firms resume delayed projects after the pandemic, including in tourism-related activities and manufacturing. Exports are projected to be robust, thanks to stronger services exports amid rising tourist arrivals. As China fully reopened in March 2023, further increases in tourist inflows are expected. There is still some way to go before reaching pre-pandemic levels of tourist arrivals, as these were almost 4 times higher in 2019 than in 2022.

Both services and merchandise exports will continue to be buoyed by growth in China, which is Thailand’s third biggest export destination, after ASEAN and the United States (Figure 1.7). Commodities such as plastic and rubber and agricultural products are the main merchandise export items to China (Figure 1.8). On the other hand, moderate demand from advanced economies, including the United States, EU, and Japan, which account for around 34% of exports, is expected to limit export growth.

Downside risks persist given the persistent uncertainties surrounding the global economic outlook. Central banks in major advanced economies have been raising policy rates to fight inflationary pressures. This could lead to weaker-than-expected external demand. If global trade continues to be subdued, Thai exporters, which are actively participating in global value chains, will be no exception to these weaker prospects.

As a large importer of oil, Thailand remains vulnerable to swings in global energy prices. Moreover, Russia’s prolonged war against Ukraine could lead to a resurgence in supply chain disruptions and cause energy prices to rise again. Although Russia and Ukraine accounted for a small share in Thailand’s total merchandise trade before the war, Thailand’s high merchandise trade-to-GDP ratio (113% in 2022) renders the economy highly vulnerable to the uncertain external conditions caused by Russia’s aggression against Ukraine.

Thailand’s economy has in the past proven vulnerable to sudden changes in market sentiment, which could exacerbate volatility in highly interdependent financial markets. Foreign exchange markets experienced an increase in volatility amid heightened uncertainties in global financial markets in 2022. After a sustained period of depreciation between 2021 and late 2022, the Thai baht started to appreciate against the US dollar in late 2022, along with other Asian currencies (Figure 1.9). The strength partly reflects a strong rebound of the Thai tourism sector. While this may partially help alleviate inflationary pressures, it may also weigh on the price competitiveness of Thai exporting companies. In late 2023, the Thai baht experienced a depreciation.

Amid tighter global financial market conditions, authorities will need to stand ready to respond swiftly if major downside risks were to materialise. The differential between the US policy rates and the Bank of Thailand’s policy rate has reversed and widened from 0.3 percentage points in March 2022, when the policy rate was first raised in the United States, to -2.9 percentage points in October 2023. This differential implies risks related to sudden changes in market sentiment that could trigger sudden portfolio capital outflows, which call for close monitoring.

Thailand’s official foreign reserves remained ample at 226% of short-term external debt with less than one year maturity in late 2022, although down from 275% a year earlier. Reserves are now recovering with the rebound of tourism and re-evaluation effects. As of October 2023, foreign reserves reached 211 billion USD or 44% of 2022 GDP, close to the pre-pandemic level of 217 billion USD in 2019.

The capital account recorded a surplus in 2022, as residents’ capital outflows and non-residents’ capital inflows offset each other in most periods. Since the onset of the pandemic, authorities have granted greater flexibility to non-residents to support capital inflows. Under the newly introduced non-resident qualified company scheme in July 2021, some non-resident companies can now manage currency risks more freely without providing transaction proofs and without being subject to the account limit of THB 200 million (approximately USD 6 million). In April 2022, authorities also relaxed foreign exchange regulations on residents. For example, the previous limit of USD 50 million per year for lending to foreign companies and the purchase of foreign property has been removed. These relaxed regulations aim at allowing investors more flexibility as well as reducing transaction costs, which is expected to strengthen market resilience. Some studies suggest that in times of financial distress, past outflows of capital by residents could return, potentially injecting valuable liquidity into domestic markets and alleviating financial instability (Cavallo, Izquierdo and León-Díaz, 2020[8]), (Caballero and Simsek, 2020[9]). In the long term, upgrading the framework to international standards would help to facilitate a gradual liberalisation of capital flows while managing short-term disruptions.

The financial sector appears sound overall, according to analysis by the Bank of Thailand (BOT, 2023[10]). Nevertheless, some segments warrant close monitoring over the near future. Commercial banks are well capitalised, with a capital adequacy ratio of 19.7% in April 2023, well above the minimum regulatory requirement of 11%. In 2023Q1, Thailand’s capital adequacy ratio of 19.1% was higher than in peer economies such as the Philippines (15.8%) and Malaysia (18.6%) (Figure 1.10, Panel A). Banks also recorded a high liquidity coverage ratio at 196% in September 2023, almost twice the minimum requirement ratio of 100%.

High private sector debt remains a key risk, with household and corporate debt summing up to 178% of GDP in 2023Q1, up from 160% at the end of 2019 (Figure 1.10, Panel B). In a regional comparison based on 2021 data, Thailand’s private debt to GDP ratio of then 180% was sizeable compared to regional peers such as Malaysia (143%) and Indonesia (42%), although smaller than in Singapore (221%). This reflects Thailand’s progress in financial development, but high level of private debt will need to be carefully monitored in a context of rising interest rates.

At present, the quality of banks’ loan portfolios does not seem to be much affected. The share of non-performing loans (NPLs), at 2.8% of total gross loans in 2023Q2, is slightly lower than pre-pandemic levels, but higher than in peers like Malaysia (1.8%) and Indonesia (2.1%) (Figure 1.10, Panels C and D). Household mortgages accounted for 46% of total household loans in 2023Q1 and are mostly based on fixed interest rates.

Loans to small and medium enterprises (SMEs) have a higher non-performing loan (NPL) ratio than the remaining loan portfolio and have seen an increase in delinquency from 6.4% in 2020Q3 to 7.4% in 2023Q3. The authorities provided additional liquidity with a higher credit limit and longer maturities and provided access to loan guarantees targeted to vulnerable SMEs and households in 2021 to cushion the prolonged impact of the pandemic and introduced a new debt restructuring programme. These measures have been helpful to reduce the debt service burden of constrained SMEs and households and to support viable SMEs, but the additional liquidity measures should be phased out progressively to avoid contributing to a build-up of private sector debt.

The Bank of Thailand is undertaking regular stress tests of commercial banks and non-bank financial institutions, but the results of these tests are not generally disclosed. Regular disclosures of stress tests can help to monitor the build-up of systemic risks and allow proactive evaluations of financial vulnerabilities ahead of time (Marques et al., 2022[11]) (Puah, Kuek and Arip, 2017[12]). The disclosure of stress test results can also serve as an effective communication tool, providing the market with information on the risks of banks’ balance sheets. Major central banks are also increasingly including climate risk assessments in their stress tests. Considering Thailand’s susceptibility to climate risks in the region, implementing such assessments would be particularly relevant.

Current license requirements can act as an impediment for business to access financing. Hotels, for example, are required to comply with several laws and regulations, but a sizeable number of hotels and accommodations across the country fail to do so, effectively operating without a license. Enforcement of license requirements was halted during the pandemic. Reviewing those license requirements and assisting existing businesses on their way towards becoming compliant would allow these businesses to access loans.

The most immediate short-term challenge for Thailand will be to move from the broad policy support measures designed in the context of Covid-19 and high inflation towards well-targeted permanent social protection instruments to support those most in need, while consolidating fiscal accounts. Fiscal and monetary policies should work hand in hand, avoiding conflicting impulses on the economy between the two. This implies phasing out the emergency support measures put in place over the last years, including fuel tax reductions.

High energy and commodity prices have dramatically changed Thailand’s inflation environment. Global energy and commodity prices soared in 2021, pushing up energy prices and creating a gap between headline and core CPI inflation (Figure 1.11, Panel A). Inflation overshot the target range of 1%–3% in 2022, and inflationary expectations spiked to 4.8% in July 2022. Currency depreciation against a strong US dollar in late 2022 exacerbated the impact of high energy prices via imported fuel prices, although partly mitigated by fuel subsidies. The energy component of the CPI, about one eighth of the CPI basket, increased by 25.0% in 2022, accelerating from 11.9% in 2021. In addition, an outbreak of the African swine fever in January 2022 contributed temporarily to high inflation, raising meat prices by 21.1% in annual terms. Overall, headline inflation increased to 6.1% on average in 2022, up from 1.2% in 2021, recording the highest rate in the last two decades. The last time that inflation had been so high was in 1998, when it reached 8.0%. Core CPI inflation increased from 0.2% in 2021 to 2.5% in 2022.

In response, the Bank of Thailand started to raise its policy rate in August 2022 (Figure 1.11, Panel B). The policy tightening was slower and more moderate than in other countries, including regional peers. With the tourism sector almost shut down, the economic recovery was still significantly weaker than in regional peers until mid-2022. On the other hand, energy imports implied high inflationary pressures, which were partly mitigated by price controls. Prices for 56 goods and 5 services including basic staples such as eggs, rice or medicines are controlled by the Central Committee on the Price of Goods and Services (CCP). As a result, inflation expectations remained rather stable throughout 2022, despite the large overshoot of actual CPI inflation, prompting the BOT to maintain an accommodative policy stance until mid-2022. As global energy prices receded and the temporary impact of the African swine fever dissipated, inflation started to decline gradually in the second half of 2022. Year-on-year headline inflation decreased to 2.7% in April 2023, falling back into the target range of 1%–3%, after having peaked at 7.9% in August 2022. Subsequently, headline inflation rate declined further to –0.3% in October 2023, below the target range, mainly due to further declines in oil prices, energy subsidies and base effects.

Looking ahead, pressures on core inflation are expected to remain in the short term due to the continued recovery of domestic demand and a continued rebound of international tourism. Rising input prices have compressed profit margins, but firms are expected to pass on some of these cost increases to consumers as domestic demand gains momentum. The recovery of the Chinese economy, including tourist inflows, is supporting growth but may add to inflationary pressures by boosting demand for energy and commodities. Moreover, labour shortages in several sectors including tourism are likely to exacerbate wage pressures. The minimum wage was raised in October 2022 and further increases are under consideration. In the second half of 2022, nominal unit labour costs rose rapidly as wage growth outpaced labour productivity growth, with a year-on-year increase of 9.7% in the third quarter of 2022. This represents the most rapid increase of unit labour costs in a decade.

Against this background, the current monetary policy stance should be maintained. Inflation expectations for one year ahead remain at 3.1% as of October 2023, above current inflation and slightly above the 3% upper bound of the inflation target range. This implies a negative ex-ante real interest rate of –0.6%, which is close to the December 2019 level of –0.4%. Inflation is projected to reach 1.6% in 2023, rebound to 2.2% in 2024, before declining to 2.0% in 2025.

Thailand’s fiscal deficit widened in the fiscal year that began on October 1, 2020 (FY2021) as the government took a series of additional support measures against the economic fallout from the pandemic and later high energy prices (Figure 1.12). The general government headline fiscal balance reached a low of -5.0% of GDP in FY2020 and -4.6% in FY2021, before improving to a deficit of -3.9% in FY2022 as some of the pandemic relief measures were withdrawn and public expenditures declined. Two major pandemic relief packages announced in April 2020 and May 2021, amounting to 9.4% of GDP, have been almost fully disbursed at 96%, including cash transfers, and to a lesser extent health spending and measures to support economic growth. Further support measures in the second half of 2022 included a subsidy programme and cash transfers to mitigate the impact of rising energy prices. A cap on diesel prices is estimated to have caused a fiscal cost of 1.1% of GDP, although part of the cost was born by the State Oil Fund whose aim is to cushion the economy against oil price fluctuations (World Bank, 2022[13]).

In the current fiscal year FY2023, existing relief measures will be gradually phased out, as global commodity and oil prices have receded. In particular, energy-related support will expire during 2023, with the excise tax cut on diesel by THB 5 per litre extended to July 2023, although the authorities are considering an additional two-month extension until September 2023. Spending will be lower overall, with a smaller budget for current expenses and more room for investment. In addition to lower spending, the robust rebound of economic activity is expected to push up tax revenues in 2023. This will help to achieve the current budget projections of a -3.7% of GDP general government fiscal balance in FY2023. Medium-term projections foresee further consolidation to -2.8% of GDP by FY2026.

In the short run, Thailand should continue to pursue the current gradual fiscal consolidation plans as domestic demand firms, including by withdrawing extraordinary policy support. This will also support monetary policy in its efforts to tame remaining inflationary pressures and help to rebuild a fiscal buffer to prepare the future shocks. A stronger fiscal position will also help Thailand meet the growing spending needs to address structural challenges, such as the transition to a green economy and population ageing.

Thailand’s public debt stood at 62.1% of GDP in September 2023. This is similar to the average for emerging market economies, but should be evaluated in light of Thailand’s low tax intake of 16% of GDP. The government raised the public debt ceiling to 70% in October 2021, departing from its self-imposed fiscal rule to keep the public debt-to-GDP ratio below 60%, after the Public Debt Management Office (PDMO) announced two Emergency Decrees in 2020 and 2021 that allowed additional borrowing. The new fiscal rule was administered in line with the Fiscal Responsibility Act, which mandates revising the limit every three years. Although such flexibility helped Thailand implement relief measures in a timely manner, it also caused an inevitable delay in fiscal consolidation. (OECD, 2022[14])

Medium-term fiscal planning is achieved through the Medium-Term Fiscal Framework (MTFF), which defines guidelines for next three to five years and is revised annually. Its long-term anchor is the public debt ceiling rule. Setting a clear timeline to lower the public debt limit back to the previous 60% of GDP in the medium term will strengthen the medium to long-term sustainability of fiscal accounts. Tighter fiscal rules can be one way to address growing fiscal pressures from rapid population ageing, an avenue recently chosen by Korea (OECD, 2022[14]).

According to the MTFF for FY2024-2027 released in December 2022, public debt is expected to stay below 62% of GDP, peaking at 61.8% in FY2025 and then falling to 61.3% in FY2027. Looking further ahead, population ageing will call for additional expenses, reaching up to an additional 1.4 percentage point of GDP by 2050, even under the conservative assumption of constant per-person spending for the elderly. This will push up social spending from the current 5% of GDP to 6.5%. To maintain the primary fiscal balance at -1% of GDP in the medium term, this additional spending will need to be financed through compensatory measures in the form of additional tax revenues. OECD simulations suggest that with these compensatory fiscal measures amounting to 1.7% of GDP fully implemented by 2035, gross public debt is expected to converge to around 60% of GDP by the mid-2040 (Figure 1.13). Even if only half of these compensation measures were implemented by 2035, public debt would not exceed the current 70% ceiling until 2045. However, if rising spending pressures are not met with additional fiscal measures, gross public debt would continue growing and rise as high as 90% by 2050. By contrast, higher real GDP growth, for example through productivity-enhancing reforms, would allow gross public debt to decline to below 50% of GDP.

Fiscal reforms will be inevitable to face future spending needs while ensuring debt sustainability. There is scope to create this additional fiscal space on the revenue side, but also by eliminating some unnecessary current expenditures, including fuel subsidies. Potential reforms to improve the structure of both public spending and revenues will be discussed in the subsequent sections, with a summary of their potential medium-term fiscal impact presented in Table 1.6.

Public investment is key for enhancing productivity and the economy’s long-term growth potential. A current fiscal rule earmarks at least the amount of new government borrowing and at least 20% of the annual budget for capital outlays. In FY2022, capital expenditure was far less than net borrowing and amounted to only 19.7% of the annual budget, although this was later addressed in a remedial plan that included additional investment.

Maintaining strong investment will be key for future growth, and urgently needed in the context of the green transition, but it will also become politically more challenging to sustain investment in the context of rising spending pressures, such as those resulting from population ageing. Over the last years, public investment has been financing mostly infrastructure projects including railways, roads, irrigation system and energy sector. Ensuring sufficient public investment is even more important as actual investment disbursements tend to fall short of the budget. While current expenditures in the budget were fully disbursed, only 68% of capital spending foreseen in the budget was actually disbursed. Actual capital expenditure thus accounted for 14% of total government expenditure, well below the budgetary minimum target of 20%. Disbursement procedures could be accelerated by giving a stronger role to the Committee on Government Budget Disbursement Monitoring and Acceleration chaired by the Minister of Finance, and ensuring frequent meetings of this Committee.

Beyond investing in physical capital, there is also a strong case to boost investment in human capital, which is one of the pillars of sustained productivity growth. In the aftermath of the pandemic, public education spending has become a priority for Thailand. The pandemic caused learning losses in most countries and particularly in developing countries, as education spending was often neglected (World Bank and UNESCO, 2022[15]). Even before the pandemic, however, education spending was on a downward trend in Thailand, and this trend accelerated during the pandemic (Figure 1.14). Thailand’s education spending accounted for 14.6% of total government expenses in FY2022, a significant decline from 21.9% in FY2014. Thailand’s educational outcomes measured by PISA scores in reading, mathematics, and science are relatively low compared to regional peers such as Malaysia. The PISA score in reading fell to 393 in 2018, recording the lowest level since the introduction of PISA in 2000, and may have declined further during the pandemic. Higher spending efficiency in education, including through school funding linked to performance improvements would allow achieving better education outcomes in the future.

Against the background of rapid population ageing, future spending pressures are likely to require higher tax revenues. Already, Thailand’s old-age dependency ratio is not only higher than in other countries in the region, but it is also rising faster (Figure 1.15). The working-age population aged 15-64 is anticipated to decline from 70% of the population in 2021 to 60% in 2040, while the proportion of those aged 65 and above will rapidly increase from 15% to 27% during the same period.

At the same time, tax revenue collection in Thailand has declined due to emergency tax relief measures and lower economic activity during the pandemic. As relief measures are lifted and economic activity rebounds, tax revenues are expected to see a cyclical rebound, but that may not be sufficient to address the structural spending pressures stemming from an ageing population, the need for stronger social protection and the costs of addressing climate change.

Thailand’s tax revenues are low in international comparison and could be raised by broadening tax bases and improving tax compliance (Figure 1.16). The low tax revenues reflect Thailand’s narrow tax bases and a high degree of informality among firms and workers (OECD, 2020[1]). Informal workers currently account for more than 50% of the workforce. Even if the prospective short-term gains in tax revenues associated with bringing more workers into the tax system may in most cases be limited given the lower incomes of informal workers, this should be seen as a useful long-term investment into ensuring sustainable future tax revenues and could also help to improve workers’ access to public social protection schemes and strengthen the delivery of targeted social benefits.

Making the tax system more progressive could help reduce income inequalities. These have improved over the past decades, but the tax and transfer system has played a relatively limited role in this process (Figure 1.17). More than 50% of total tax revenue comes from indirect taxes such as value-added taxes (VAT), which typically offer little scope for progressive taxation. Excise tax and import duties, which fall into the category of special taxes on goods and services, also have a stronger weight than in other countries. This contrasts with the personal income tax, which is used much less in Thailand than in the average OECD country. Less than 15% of the Thai population is subject to personal income taxes, partly related to the large informal sector.

One way to collect more revenues from the personal income tax would be to reconsider some of its current tax expenditures. Many of the current tax expenditures benefit households with higher incomes, such as the current tax allowances for life insurance premiums, mortgage interest payments and investments in long-term equity funds. Although these allowances are capped, the current cap of THB 100,000 for life insurance premiums or home mortgage interest amounts to more than half an average annual wage income, and the allowance for long-term equity funds is even greater with a maximum of THB 500,000. Phasing out these allowances would clearly strengthen the progressivity of the personal income tax.

The current basic allowance exempts net annual income below THB 312,000 (USD 4,420) from personal income taxes, which is about 170% of the average wage income. As a result of this high threshold, even many university graduates are not subject to paying any personal income taxes on their salaries. Above this threshold, a first bracket starts with a 5% rate, and 19% of taxpayers currently fall into this range.

A lower entry rate in personal income taxes will be helpful for bringing more individuals into the personal income tax system, which would be a first step towards a gradual expansion of the tax base. Above the entry rate, a progressive rate schedule would allow more redistribution through the tax system, while a flatter schedule would imply lower disincentives to entrepreneurship and investment. In light of strong income inequalities and a current rate schedule with 6 additional income brackets and a top marginal tax rate of 35% that applies only to very high income levels, there appears to be scope for raising personal income tax revenues from the upper parts of the income distribution, without raising the top marginal rax rate and without increasing the tax burden on lower-income households.

Corporate income taxes also present scope for reviewing the effectiveness of tax expenditures, which are often generous and aimed at attracting investments. The introduction of the global minimum effective tax rate of 15% will make some of the generous tax incentives obsolete for firms within the scope of this tax, which include multinational enterprises with annual revenues above EUR 750 million (OECD, 2021[16]). Thailand approved in principle the introduction of the global minimum tax in March 2023, and the implementation into domestic legislation is now underway.

A new recurrent tax on immovable property, was introduced in 2019, which can also contribute to a more progressive tax system in Thailand. Local governments collect the land and building tax based on the value of property, which is measured by the Treasury Department of the Ministry of Finance. The tax only applies to immovable properties above THB 50 million (approximately USD 1.5 million) in property value, with varying rates based on their usage. Agricultural properties have a comparatively low maximum rate of 0.15%, while residential properties are taxed at up to 0.3%. Vacant or properties used for other purposes such as business activities can face rates of up to 1.2%. Another positive feature of this property tax is that it does not require individual filing. Instead, the Department of Land under the Ministry of Agriculture and Cooperatives directly collects information on the land use and imposes the tax, which improves administrative efficiency.

A full implementation of the recurrent tax on immovable property, however, is still outstanding. Due to the pandemic, the effective date of the tax was postponed until August 2020 and the tax rate was temporarily reduced by 90% in 2020 and 2021 to mitigate the burden on households. The rate then returned to what was planned initially, before being reduced again by 15% in 2023. The tax should now be fully implemented at its originally planned rates, including with enhanced monitoring to avoid possible tax evasion. Reports of idle urban properties being declared as agricultural land to avoid the higher tax rate on undeveloped land suggest that better monitoring of the actual land use, in line with zoning regulations, would be one way to get more revenues from the new property tax. Another way would be through more frequent re-evaluations of property values, which currently take place every 4 years. Singapore updates property values every year, while the Philippines do so every three years (OECD, 2023[17]). Information-sharing among related government agencies and local authorities could support the re-evaluation process and strengthen tax compliance.

Thailand’s statutory VAT rate was originally set at 10% in 1997 but the effective rate was later reduced to 7% in the aftermath of the 1997 Asian Financial Crisis. The application of this lower rate has been extended numerous times since then, but it is relatively low compared to regional peers including Indonesia (11%), the Philippines (12%), Viet Nam (10%) and Malaysia (10%) and other emerging economies such as Mexico (16%), Colombia (19%) and South Africa (15%). The rate should now return to the original 10% and could even be raised further in light of rising future expenditure pressures. Apart from its low rate, Thailand’s VAT appears to be relatively effective on the basis of available data, delivering 81% of potential revenues obtained by subjecting all domestic private consumption by the standard rate in 2022. This exceeds the OECD average of 56% in 2020 (OECD, 2022[18]).

Taxes on the transfer of wealth like inheritance and gift taxes can also be an effective way to reduce inequalities, including inequalities of opportunities. Compared to other taxes on wealth, inheritance and gift taxes can effectively reduce inequality with little harm to economic efficiency (OECD, 2021[19]). After decades-long debate, Thailand introduced inheritance and gift taxes in 2015, with a 10% rate on inheritances and 5% on gifts, which may provide room for arbitrage (Siriprapanukul, 2014[20]). Aligning the rates of inheritance and gift taxes can help obtain neutrality between wealth transfers during lifetime and at death (OECD, 2021). The current inheritance and gift tax rates are also relatively low compared to other countries, and raising it further, including with progressive tax brackets, could be an option for the future. In addition, the automatic exchange of information (AEOI) can help ensure that tax residents declare and pay tax on capital income earned abroad, which could potentially raise tax revenue as well as progressivity and fairness of tax system. Thailand has committed to voluntarily undertake the first automatic information exchanges by 2023, which is a welcome step.

Besides potential changes in the tax code, a stronger enforcement of existing rules through better tax administration could also lead to further revenue improvements. One way to strengthen tax compliance would be to harness digital technologies, which could reduce the cost of enforcement for the authorities and lower the reporting burden for taxpayers. With its unique personal identifier assigned to each citizen on their national identity card, Thailand is well-prepared to make further inroads on tax enforcement through digital means. For example, a new electronic tax filing system enhanced service efficiency with enabling quick access to its online tax services in 2021.

E-commerce is an area that readily benefits from the application of digital technology. A 2021 law imposed VAT on cross-border digital services to non-VAT registrants resident in Thailand. Foreign platform operators with income from services provided in Thailand of over THB 1.8 million (around USD 51,800) are now required to register and pay VAT. The new tax rules on e-commerce aim to increase tax revenue and foster a level playing field between Thai and foreign companies in e-service markets.

Greater adoption of digital technologies in the government sector would allow strong synergies across different areas, notably, tax collection and social protection (OECD, 2022[21]). Digital tools and digitally integrated administrative data including tax registries can improve the targeting of various benefits and facilitate formalisation. Digitalisation of government services would also be useful for regulatory reforms, such as streamlining administrative procedures.

Strong competition is crucial for boosting productivity growth, which has been subdued over the last 20 years (Figure 1.18). Competition is the necessary force to allow the most productive and innovative firms to grow, including at the expense of less efficient incumbents. Only this creative destruction process provides the right incentives for firms to invest in constant improvements of products and processes. Where it is hampered, this can trap resources in low-productivity firms with fewer investment opportunities and curtail incentives for innovation and technological upgrading.

A large body of empirical evidence suggests a link between stronger competition and productivity gains. Regulations that hamper competition have been found to slow down the process by which countries with lower levels of productivity can catch up with high-productivity economies (Nicoletti and Scarpetta, 2003[22]; Arnold, Nicoletti and Scarpetta, 2011[23]). These effects can work through imposing greater discipline for eliminating inefficiencies and adopting the best technologies within the same sector (Syverson, 2004[24]), but they can also work across sectors through sourcing relationships, as competition in intermediate goods markets can improve productivity downstream (Bourlès et al., 2013[25]; Arnold et al., 2016[26]; Arnold, Javorcik and Mattoo, 2011[27]). In India, for example, stronger competition in services sectors has brought significant productivity benefits for downstream manufacturing sectors using these services as inputs (Arnold et al., 2016[26]).

Finally, stronger competition can also foster reallocations of resources towards more productive firms, either through the entry and rapid growth of more productive start-ups, or through accelerating the exit of low-productivity firms and freeing up resources for more productive competitors (Olley and Pakes, 1996[28]). Open markets with low entry barriers would allow high-performing small and medium enterprises to compete and prosper on a level playing field, which is currently not always guaranteed in the face of dominant market positions prevalent in some sectors. Reducing entry barriers may even provide more effective support to high-potential start-ups than specific support policies to SMEs, which often have much higher budgetary costs.

Moreover, economic rents can arise when policies shield parts of the economy from competition. These policies can then end up redistributing resources towards the affluent and even make the political decision-making process less transparent. At the same time, such policy settings reward firms for seeking political connections rather than performing better. Against this background, ensuring an equal playing field and low entry barriers in all sectors will be a key priority, both to reduce inequalities in incomes and opportunities and to boost productivity. Strengthening competition is also conducive to stimulating both foreign and domestic investments, including by SMEs.

Evidence suggests that a range of Thai industries are characterised by high concentration and low levels of competition, which tends to foster rigid industry structures in which strong performers find it more difficult to grow at the expense of low-productivity firms. Thailand ranked 85th out of 141 countries in an indicator about the extent of market dominance elaborated by the World Economic Forum, suggesting that many markets for products and services are dominated by a few players. Thailand’s performance on this indicator is significantly behind that of regional peers such as Malaysia and Singapore. Analysis based on administrative data of Thai registered firms suggests an increase in market power among Thai firms, which coincided with lower business dynamism (Apaitan et al., 2020[29]).

Structural impediments to competition have been identified across a wide range of sectors, perhaps most notably in services where regulatory constraints inhibit effective competition (ADB, 2015[30]). This has coincided with weak services productivity growth, in stark contrast to other Asian economies (ADB, 2015[30]). In October 2022, a merger of two big telecommunication companies was approved, creating a market leader with a total of 55 million subscribers in a country of 71 million inhabitants, surpassing the previous market leader, which had 44 million subscribers. This duopoly may have a risk of weakening the competitive climate of the mobile network operator market. Also, an acquisition of a big retail supermarket by its competitor in 2020 has led to a strong and potentially dominant market position in the retail sector. Beyond services, restrictive alcohol laws hamper market entry into several alcoholic beverage markets including beer brewing, which is highly concentrated.

Market dominance is a notable feature of the energy sector, particularly in the natural gas and electricity industries. Since its inception in 1981, the gas industry has been dominated by a state-owned enterprise with substantial investments and long-term contractual agreements. For instance, power plants typically sign contracts that span up to 25 years, and individual contracts do not expire simultaneously, making it challenging for new entrants to compete. Furthermore, the structure of the electricity industry, with its dominance of the Enhanced Single Buyer Model purchasing electricity from Independent Power Producer and Small Power Producer to distribute to consumers under the retail tariff, hampers the efficient and effective transmission of electric energy to end-users.

The dominance of conglomerates in Thailand has been steadily growing over the past few decades. The top 5 percent of companies now control over 85 percent of the total revenue, and this trend is expected to continue. This concentration of business ownership is not limited to a few select industries; it is prevalent across various sectors, including liquor production, beer production, beverage and tobacco retail, and plastic production (Apaitan et al., 2019[31]). High concentration often affords greater market power, as reflected in higher markups, and it also has a negative impact on productivity and investment in the domestic market (Apaitan et al., 2020[29]). Firms that do not face strong competitive pressures at home will also face challenges in competing abroad and expanding their presence in foreign markets, which ultimately affects the country's competitive position on the international stage.

State-owned enterprises (SOEs) remain present in a number of sectors, at times competing with private enterprises. This may give rise to an uneven playing field between private companies and SOEs, which is likely to hamper competition. The 2017 competition law, repealing and replacing the previous law in 1999, eliminated an exemption for state-owned enterprises in a broad range of business sectors. Nonetheless, some sectors, such as telecommunications and energy, are not covered by this law, and SOE activities that concern national security and public interest are exempted. Cooperation between the competition authority and regulatory authorities of these sectors can be strengthened to ensure coherent competition policies across the economy. Clarifying the scope of SOE activities concerning and the public interest exemption is also important (OECD, 2020[1]). One step forward would be to require state-owned enterprises to keep separate accounts for those activities where they fulfil a public-interest mandate and those activities where they do not, to avoid cross-subsidies towards the competitive segments.

Given the size of Thailand’s SOEs, their performance has significant implications for public finances. Some SOEs in the public transportation sector have been making losses, and the government has developed a rehabilitation plan for these SOEs. Further losses could potentially present financial risks for public accounts. Aligning SOE governance frameworks with the OECD Guidelines on Corporate Governance of State-Owned Enterprises would reduce the likelihood of such losses in the future, and level the playing field for competition with private enterprises (OECD, 2015[32]).

Although strengthening competition should become a priority focus for a wide range of policies, the institutional framework for competition policy is the 2017 competition law, which was widely perceived as a step towards international standards. This law established the Trade Competition Commission (TCC) as Thailand’s competition authority, as well as addressing some concerns regarding market dominance and anticompetitive agreements. The law applies to a broad range of business sectors; nonetheless, some key services sectors such as telecommunications and energy have been excluded from this law. Looking ahead, there is scope for mainstreaming competition principles across the whole of government. Clearer guidance in the National Development Plan could lay the institutional basis for this, as it would encourage agencies and ministries to give more priority to promoting competition.

Providing more resources to the competition authority would allow it to spend more efforts on monitoring both concentration and conduct, including through market studies. Most investigators are currently working on merger cases, with little resources left for structural reviews and stocktaking exercises in specific sectors.

A comprehensive competition review in key sectors could help to identify regulations that stand in the way of stronger competition. This may include scope to reduce administrative burdens and streamline licensing procedures for new businesses, or to review sector-specific regulations that were originally designed for another purpose but end up creating barriers to competition. Widespread price controls could also be reviewed more systematically to see if they are still needed, and new price controls could include built-in sunset clauses. The OECD’s Competition Assessment Toolkit (OECD, 2019) can provide guidance not only for identifying but also for revising policies that unduly restrict competition. Although Thailand conducted a regulatory reform with the “Regulatory Guillotine” and “Simple and Smart Licence” programme in 2017 to repeal or revise outdated regulations (OECD, 2020[1]), the reform lost steam over the past few years. There has nonetheless been some progress during the pandemic, when a number of laws and regulations were amended to adapt to emergency situations, such as legalising telemedicine and relaxing work permits for foreign workers.

Thailand has reaped significant productivity benefits from foreign direct investment (FDI), which has fostered its integration into international production networks. Compared to other Southeast Asian countries (Figure 1.19), however, inward FDI stocks still have scope for further increases. While countries like Indonesia and Malaysia experienced a substantial increase in foreign investment in 2021 and 2022, Thailand saw only a minor improvement. The current geopolitical context may provide opportunities for Thailand to attract further investment as multinational companies revisit their investment portfolios with a view towards diversifying their exposure across countries in Asia.

Thailand’s new FDI strategy adopted in October 2022, the 5-Year Investment Promotion Strategy for the New Economy for 2023-2027, focuses on promoting high-technology, innovation, and green industries such as electric vehicles. A planned extension of the special economic corridors (SECs) into four new geographic areas will complement current policy initiatives focused on the existing Eastern Economic Corridor (EEC). Each new SEC will target specific industries based on close cooperation with regional universities to promote innovation. These plans can build on previous experiences learned in the current special economic corridor and should put more emphasis on cooperation among these corridors.

The new strategy has been complemented by efforts to attract high-skilled foreign workers. A special visa programme of 2018, called the SMART Visa programme, expedites immigration procedures for skilled workers. For 13 targeted industries such as automobiles and digital technology, the programme provides a four-year visa instead of the standard one-year visa. In September 2022, the authorities expanded the programme by adding five additional targeted industries such as national defence and aviation and aerospace industry. In September 2022, a new Long-Term Resident (LTR) Visa programme was established to attract high-skilled foreign workers and wealthy pensioners with diverse tax and non-tax benefits, including a reduced PIT rate of 17% and full tax exemption for overseas income. The programme offers a 10-year renewable visa as well as an exemption from the requirement to employ 4 Thai workers for every foreign worker.

Further policy efforts to stimulate FDI inflows could include easing existing restrictions. Based on the OECD FDI Restrictiveness Index, Thailand’s policies are more restrictive than in regional peers, and this holds particularly true for many services sectors (Figure 1.20). Specifically, foreign equity restrictions and the FDI screening and approval process are more stringent than in OECD and ASEAN countries (OECD, 2021[33]). Regulatory reforms such as those required to strengthen competition and enhance the business climate will also be instrumental to attract more FDI. Indonesia, for example, has taken this road by enacting the Omnibus Law on Job Creation in October 2020, revising 79 laws and eliminating thousands of regulations across 10 broad areas, including a labour reform and improvements in the ease of doing business (OECD, 2022[34])

In light of the recent disruptions in global supply chains, trade facilitation has attracted increasing attention. Thailand has made good progress since the ratification of the Trade Facilitation Agreement of the World Trade Organisation in October 2015. The rate of implementation commitments is 98.7%, surpassing the Southeast Asian average rate of 82.9%. Judging by its score on the OECD Trade Facilitation Indicators, Thailand made significant progress in trade facilitation between 2017 and 2022, with a higher score than the average upper-middle income country and the average Asia-Pacific country, especially in the areas of appeal procedure and automation (Figure 1.21). Room for further improvement exists with respect to fees and charges, suggesting that Thailand could further facilitate trade by reducing services fees as well as by improving online access to information on applicable fees and charges.

Additional export opportunities could arise from stronger trade integration, by expanding the current network of preferential trade agreements (PTAs). In November 2021, Thailand ratified the Regional Comprehensive Economic Partnership (RCEP), which took effect in January 2022. With 15 members countries, accounting for around 30% of global GDP, the RCEP will enable Thai exporters to gain better market access in the Asia Pacific region with reduced tariffs. In March 2023, Thailand and the EU announced to resume negotiations on the Thailand-EU Free Trade Agreement (FTA), which had stalled in 2014. This bilateral FTA is expected to boost trade and investment flows with the EU, strengthening the two countries’ well-established trade relationship. The first negotiations took place in September 2023, and the second round is scheduled for January 2024. Thailand has yet to decide on its participation in the Comprehensive and Progressive Agreement for Trans--Pacific Partnership, another major free trade agreement.

Opening up services markets to competition and foreign direct investment will be key for moving into higher-value ladders of global value chains. Evidence suggests that access to more competitive services inputs, including as a result of foreign direct investment in services, can have significant productivity benefits for downstream manufacturing companies (Arnold et al., 2016[26]; Arnold, Javorcik and Mattoo, 2011[27]). While Thailand has made progress towards stronger foreign competition in services, the pace of reforms has slowed in recent years. Thailand’s score of the OECD Services Trade Restrictiveness Index is rather high compared to other countries, indicating a relatively stringent regulatory environment (Figure 1.22). Accounting and rail freight services are the most restrictive sectors. In particular, restrictions to foreign entry including screening of foreign investments, residency requirements for management staff and restrictions related to cross-border transfer of personal data contribute to this relatively unfavourable score, in addition to restrictions related to the movement of people such as duration of stay for service suppliers and labour market test for foreign workforce. Thailand’s Foreign Business Act (1999) restricts market access for certain services, for instance in construction services, distribution services and computer services.

Thailand has made consistent progress in strengthening its anti-corruption policy framework. Many government agencies, including the Ministry of Industry and the Board of Investment, recently pledged a no-gift policy to display transparency. In January 2023, the authorities issued strict guidelines on accepting gifts for public officials and their families.

Nonetheless, corruption indicators suggest considerable room for improvement relative to other countries in the region, including Malaysia and Viet Nam. Thailand ranked 101st out of 180 countries on the Corruption Perceptions Index in 2022 (Figure 1.23, Panel A), improving only slightly compared to the previous year. Performance on the World Bank’s Control of Corruption indicator also remains low, continuing the stagnation of past years (Figure 1.23, Panels B, C and D).

The efficiency and effectiveness of the anti-corruption policy framework are still hampered by the overlapping and conflicting mandates of anti-corruption agencies, weakening the enforcement of integrity policies (OECD, 2021[35]). For example, the National Anti-Corruption Commission (NACC) and the Public Sector Anti-Corruption Commission (PACC) are both entitled to investigate public officials, while NACC has an exclusive jurisdiction on the cases committed by high-level officials. In practice, the NACC investigates the corruption of high-level officials and refers relatively minor cases with lower-level officials to the PACC or the police. However, the referral procedure is discretionary and lengthy, creating a backlog of unresolved low-level cases as the NACC gives priority to high-level cases (Prateeppornnarong, 2020[36]). Clearer guidelines for the referral procedure as well as development of an electronic case management tool would allow a more timely investigation of corruption allegations. Some countries in the region have been successful with anti-corruption agencies specialising in the corruption of high-ranking officials. Korea, for example, established the Corruption Investigation Office for High-Ranking Officials (CIO) in 2021 (OECD, 2022[14]). The CIO is an independent agency that investigates the abuse of authority or bribery of high-ranking officials or their families. The CIO Act clearly defines the scope of investigation, including the President and the Prime Minister, and the types of crimes subject to its jurisdiction.

Stronger co-operation among anti-corruption agencies could be fostered by establishing an integrity network between anti-corruption agencies. Such a network could organise regular meetings to allow sharing good practices and lessons learned, even they are informal. Many OECD countries including Canada, Sweden, Austria and Germany have public sector integrity networks to enhance the effectiveness of their overall anti-corruption policy implementation (OECD, 2020[37]).

Collaboration with the private sector is also crucial to counter corruption effectively. In Thailand, this collaboration among anti-corruption organisations in the public and private sectors lacks a focal point, which weakens the collaboration (Yomnak and Ruckchart, 2021[38]). The NACC, for example, has been working closely with the Anti-Corruption Organization of Thailand (ACT) and the Private Sector Collective Action against Corruption (CAC), which participated in the Watch Dog campaign and the drafting of the Anti-Bribery Guidelines. Holding regular meetings and seminars to exchange information on recent measures and good practices would be beneficial to both integrity agencies and private organisations.

Thailand has made good progress in tackling money laundering and terrorism financing. According to the Asia/Pacific Group on Money Laundering (APG), Thailand demonstrated generally good compliance on 31 out of 40 the Financial Action Task Force (FATF) Recommendations in 2021, up from 25 in 2017 (2021[39]). In particular, the APG pointed out that Thailand has a robust policy and implementation framework through the National Coordinating Committee. The Anti-Money Laundering Office (AMLO), a pivotal government agency in both policy coordination and enforcement, stepped up its efforts. In 2022, AMLO disseminated the updated National Risk Assessment, after 2012 and 2016, which helped formulate the 2022-2027 National Strategy on AML/CFT (Anti-Money Laundering and Combating the Financing of Terrorism) to keep pace with international standards amid rapidly evolving financial technology.

While most OECD countries have dedicated whistle blower protection laws, Thailand does not have such a dedicated law (OECD, 2016[40]). Whistle blowers are partially protected under the Witness Protection Act and the Organic Act on Anti-Corruption, but there is no single dedicated law. The NACC can grant protection such as security arrangements for officials or providing a safe house, but the coverage is limited to qualified whistle blowers related to serious criminal cases. Many whistle blowers do not necessarily qualify for witness protection and are hence only partially protected under the witness protection laws (OECD, 2016[40]). As recommended in the previous OECD Economic Assessment of Thailand, developing a single dedicated law to protect whistle-blowers could lead to further progress in the fight against corruption (OECD, 2020[1]).

Thailand’s social protection instruments have mostly been established over the last 25 years and are organised in a number of parallel systems, which has led to significant fragmentation. Over those years, Thailand has strengthened its social safety net and achieved significant expansion in coverage, including among those not formerly covered by social protection policies. A universal public healthcare system was established in 2002. Building on this progress, Thailand can do more to reduce poverty and inequality through improvements in social protection. The main challenges for the future will be to achieve fully universal coverage with basic benefits, reconsider benefit adequacy for some benefits and improve the organisation of benefit delivery, ideally moving from a fragmented system to a single system that can deliver different tiers of benefits depending on the specific situation of beneficiaries.

Social security benefits are currently provided to contributing formal-sector employees, but these amount to only 50% of the workforce, substantially less than in other countries (Figure 1.24). The main social security scheme called Section 33 was established under the Social Security Act in 1999 and provides formal private-sector employees in registered enterprises with old-age pensions (for those aged above 60) and healthcare insurance, and since 2004 also unemployment benefits. Its financing relies on mandatory contributions of 5% of the salary for both workers and employers, topped up by a government contribution of 2.75%, for a total contribution of 12.75% of salaries. Coverage has expanded progressively since its inception in 1991, starting initially with those who worked in registered enterprises with 20 or more employees. Workers in enterprises with 10 or more employees were included in 1993, until a further expansion to all regular employees in registered enterprises regardless of their size in 2002. A separate Workmen’s Compensation Fund covers workers contributing to social security against job-related injuries, with a contribution rate of 0.2-1.0% of wages depending on the sector.

The fiscal cost of the social security scheme for private sector workers is approximately 0.85% of GDP, allowing it to charge relatively low social security contributions. But this is likely to change as more people covered by this relatively young programme reach the retirement age, as the system was only established in 1999. As it reaches maturity, the scheme’s sustainability is not guaranteed, and contribution rates will have to rise, unless other financing sources can be identified. By some estimates, a continuation of the current benefit levels would require total contribution rates to rise above 30% of salaries (ILO, 2022[41]).

Civil servants are covered by a separate contributory social security scheme, which provides pensions and healthcare services for civil servants and workers in state-owned enterprises, at a fiscal cost of around 1.7% of GDP. Benefits are higher than those of private-sector social security.

Thailand also maintains a voluntary contributory programme for self-employed workers, called Section 40, providing different combinations of pensions and healthcare. In 2019, the upper limit for contributors’ age was increased from 60 to 65. This scheme workers had failed to attract many participants before the pandemic (Figure 1.25, Panel B). During the pandemic, the government made remarkable progress in boosting participation in Section 40 scheme through cash transfers of THB 10,000 (USD 300) conditional on applicants’ participation in Section 40. The main purpose was to reach out to informal workers who were severely affected by the economic downturn. This conditional cash handout and temporary reductions in contributions approximately doubled the voluntary participation across all age groups. To what extent this higher participation achieved during the pandemic will continue in the future without financial support is not certain. A planned Independent Workers Protection Act intends to set up a new workmen’s compensation fund to provide insurance against job-related injuries for workers officially classified as independent, such as platform workers. However, given the already fragmented social security system, it is crucial to avoid adding more complexity to the system.

The current coverage of social security benefits of slightly below 50% of the population is far below the OECD average and largely related to widespread labour informality. For various reasons, the coverage of social security pensions is even lower, currently reaching only 20% of the elderly. Although in principle private firms of all sizes should participate in the section 33 social security scheme, in practice the coverage is largely limited to people working in large registered enterprises (Figure 1.25, Panel A).

Migrant workers with a regular residence or work permit accounted for around 6% of the labour force before the pandemic and originate mostly from neighbouring Myanmar, Cambodia and Lao PDR (International Organization for Migration, 2021[42]). Although no official data are available, estimates suggest an almost equal number of migrant workers without a regular residence status (International Organization for Migration, 2021[42]). Migrant workers, many of whom are seasonal or domestic workers, are more likely to be in informal employment than natives, and therefore not covered by the social security system.

The fact that a large share of the population is excluded from social security benefits is a common feature across many emerging-market and developing economies, not only in Asia but also in Latin America and Africa. Many governments have complemented formal social security with noncontributory social assistance benefits over the last two decades, and this has also been the case in Thailand.

One pillar of these non-contributory, tax-financed benefits is a non-contributory pension, called the Old Age Allowance, granting non-contributory pension benefits to all aged 60 and above, except for those who are covered by civil servant pensions. This benefit reaches over 70% of the population over the eligibility age of 60, bringing total pension coverage up to 91%. The basic benefit of THB 600-1 000 depending on age, however, is only about USD 17-28 per month in nominal terms, or 25-41% of the poverty line of USD 5.50 per day at purchasing power parity for beneficiaries aged 60-69, with slightly higher benefits for those of higher age (ILO, 2022[41]). This level of benefits has not been adjusted for inflation for over a decade and is insufficient, and raising it would go a long way towards reducing old-age poverty. At 0.5% of GDP, the fiscal cost of this programme is currently low, but its poverty reduction impact is high. Raising it to the current poverty line would cost around 1.2% of GDP, according to World Bank calculations based on 2019 data (World Bank, 2023[43]). This would reduce poverty by 2.7 percentage points, from a starting point of 6.2% in 2019. Raising benefit levels to half the poverty rate would cost 0.45% of GDP and reduce poverty by around 1.4 percentage points. Targeting of the Old-Age Allowance could be improved by restricting it to those in need who do not receive a social security pension.

A second pillar is the Universal Healthcare Coverage Scheme, which has allowed Thailand to achieve almost universal health care coverage, with a comprehensive benefit package, despite a focus on primary care. Launched in 2001, it covers general medical care and rehabilitation services, high-cost medical treatment, and emergency care for all citizens with no healthcare coverage by social security schemes. This scheme has allowed to reduce the incidence of dramatic health expenditures when household members are affected by severe illness and has helped to improve coordination of healthcare delivery through universal health information systems and beneficiary datasets (ILO, 2017[44]).

A third and more recent pillar of non-contributory benefits consists of means-tested in-kind transfers, delivered through a State Welfare Card that allows beneficiaries to make purchases of certain goods at designated stores, up to an amount of THB 200-300 per individual and month, equivalent to USD 8.50 or 13% of the poverty line. Launched in 2017, this card system was successfully used to distribute emergency support to poor households during the pandemic and currently covers 19% of the population (World Bank, 2023[43]).

The State Welfare Card system is administered by the Ministry of Finance rather than the Ministry of Social Development and Human Security that delivers the bulk of social assistance benefits, and the underlying registries are not shared across ministries. This adds to the fragmentation and significantly hampers the effectiveness of targeting of the State Welfare Card. Among the 20% of the population with the lowest incomes, around 35% receive these benefits, while still around 20% of the middle quintile of the income distribution receive this benefit. The effectiveness of the State Welfare card would hinge on improving its targeting (Phattarasukkumjorn, 2021[45]). The current number of recipients is larger than the number of people below the national poverty line (Yang, Wang and Dewina, 2020[46]), and the self-registration process could be enhanced further to reach out to all eligible people (Durongkaveroj, 2022[47]). Moving its administration to the Ministry of Social Development and Human Security while unifying the registries underlying different social assistance benefits would be key initial steps in that direction. Once its targeting has been improved, the State Welfare Card can in principle be a useful tool for delivering targeted of support measures to compensate vulnerable households for the effects of higher energy prices in the medium run, when energy prices may rise in the context of the green transition (see Chapter 2). World Bank calculations suggest that improving the targeting of the State Welfare Card by excluding higher income households and covering more low-income households while raising benefit levels to 30 of the poverty line would have a fiscal cost of around 0.4% of GDP, while reducing the poverty rate from 6.2% to 3.2% (World Bank, 2023[43]).

Labour informality affects more than one in every two workers in Thailand. These workers are not contributing to formal social security, nor can they access social security benefits or do they benefit from employment protection legislation. Labour informality is a multi-faceted challenge that is unlikely to disappear in the short run or be solved by economic growth alone, and tackling it calls for policy action along several dimensions, including improvements in incentives for formal job creation and stronger enforcement. Informality has already seen some declines over the years, as it affected almost 75% of workers at the turn of the millennium (Figure 1.26). Evidence suggests that people who became informal workers by their mid-30s often tend to stay informal for the rest of their working lives.

Social protection is one of the areas where reforms could strengthen formalisation incentives. While non-contributory benefits have helped to alleviate poverty and inequality and could achieve more inclusive growth with better targeting and higher benefit levels, they have also reduced the incentives to participate in the formal labour market. A more desirable medium-term solution would be to integrate social programmes covering formal and informal workers, which would include reducing the incidence of informality among workers and firms.

A unified social protection scheme building on existing programmes could ensure basic pensions and cash transfers to vulnerable households without any contributions, with a view towards making substantial inroads in poverty reduction. Means-tested cash benefits could also serve as insurance against unexpected income losses from dismissals, provided that they can be disbursed swiftly once such income losses occur.

Making this basic benefit tier, focused on poverty reduction, largely tax-financed would require strengthening efforts to raise more tax revenues, but it would reduce non-wage labour costs for low-income workers in the formal sector, and hence strengthen incentives for formal job creation. Low-income segments are typically the ones most affected by high informality rates. The current social security contributions of 10% of salaries drive a wedge between the cost of creating a formal job and the cost of hiring a person informally, and as the social security system matures and more people receive social security benefits, contribution rates will have to rise significantly above their current level, thus increasing the relative cost of formal job creation. Basic tax-financed or low-contribution benefits could also make it easier to provide protections for an increasing number of platform workers. The number of riders working for five large online platforms reached nearly 1 million in 2021 (Leenoi, 2021[48]).

Colombia's 2012 tax reform that reduced some social contributions shows that reducing non-wage labour costs can help to reduce informality. In the aftermath of the reform, labour informality declined visibly. Available impact evaluations suggest that the reform led to a reduction in the informality rate of several percentage points (Kugler, Kugler and Prada, 2017[49]) (Morales and Medina, 2017[50]) (Fernández and Villar, 2017[51]) (Bernal et al., 2017[52]).

Basic social protection benefits could alternatively also be delivered through a negative income tax or an earned income tax credit. Evidence suggests that the Earned Income Tax Credit in the United States has raised labour force participation (Hoynes and Patel, 2017[53]). There are also positive effects on poverty reduction, as the programme rewards work and supplements the income of low-wage workers. Similar programmes have also decreased informal employment in developing countries (Gunter, 2013[54]).

Those with higher incomes could receive additional benefits financed through social security contributions from a second tier of the social protection system, whose focus would be on delivering adequate benefit replacement ratios and facilitating consumption smoothing between working lives and retirement, rather than poverty reduction. Contributions for this second tier could become mandatory only for workers with salaries at some distance from the minimum wage, where the argument of minimising formalisation disincentives is less pressing and probably overshadowed by the need for higher benefits that ensure a decent replacement rate.

One possible example would be for mandatory social security contributions to be charged on the part of private-sector salaries that exceeds 150% of the minimum wage. This would imply some losses in social security contributions as salaries up to the contribution threshold would no longer pay contributions, estimated at 0.02% of GDP, but this could be compensated through higher contribution rates for those with higher incomes, or a lower basic allowance in personal income taxes, with an overall progressive distributional impact. This could also be accompanied by raising the maximum monthly income considered for the calculation of social security contributions of currently THB 15,000, equivalent to USD 375 or approximately 9 minimum wages. Similar multi-tier social protection setups are currently under discussion in several Latin American countries (Levy and Cruces, 2021[55]; Tuesta and Bhardwaj, 2023[56]), and have also been recommended in OECD Economic Surveys on Colombia, Chile and Peru (OECD, 2022[57]; OECD, 2022[58]).

Incentives for formalisation could be further strengthened by reviewing labour market regulations, especially employment protection legislation, which is typically only enforceable in formal labour contracts. High costs of dismissals may make firms reluctant to create formal jobs in the first place. Thailand ranks comparatively low in international comparisons of labour market flexibility. For example, it ranks 102 out of 141 countries in the World Economic Forum’s index of labour market flexibility (World Economic Forum, 2019[59]). A thorough review of employment protection legislation with a view towards improving the incentives for formal job creation could help efforts to bring more people into the formal labour market and improve their coverage with social protection benefits.

One area that would merit further consideration is a potential reduction of severance payments. While long notice periods and high severance pay reduce the economic burden of a layoff on workers, the costs related to this could lead firms to hire fewer formal workers in the first place. The number of months that a firm must give notice before dismissal and the amount of severance pay varies among OECD countries. Compared with OECD countries, Thailand's level of employment protection is high, especially in severance pay (Figure 1.27).

Efforts to improve formalisation incentives should be complemented by stronger enforcement efforts on several fronts. Employers often do not comply with reporting requirements, particularly when they are not registered companies themselves, and after reducing non-wage labour costs for employers, the case for more frequent labour inspections to enforce reporting requirements would be much stronger. In particular, enforcement capacity of social security offices is weak due to limited resources. Stronger enforcement efforts should be put in place with respect to corporate income tax, VAT, social security contributions and the respect of labour regulations, underpinned by broad information-sharing arrangements across different agencies. Using digital technologies and collaborating with local governments would support these efforts (ILO, UNICEF, IOM, and UN Women, 2022[60]). Thailand already uses a unique 13-digit personal identifier on national ID cards, and these could be linked to taxpayer records relatively easily.

The general resilience of Thailand’s labour market does not apply to young people, and the pick-up of youth employment has been weak compared with the job recovery in other age groups. Although lower than in many other countries, youth unemployment remains at record high-levels in historic comparison, especially for young women (Figure 1.28, Panel A). In addition, long-term unemployment has become more prevalent among young job seekers, with 25% looking for a job over six months, compared to below 20% prior to the pandemic. The situation of new entrants to the labour force in search of a first job has not yet shown signs of improvement (Figure 1.28, Panel B).

This high rate of youth unemployment may undermine youth’s future employability if their unemployment period is prolonged. Previous studies suggest that a population cohort that experienced high unemployment at young ages is more likely to be unemployed in later periods (OECD, 2021[61]). As part of emergency measures taken during the pandemic, many countries put particular emphasis on containing the rise of youth unemployment through measures such as targeted hiring subsidies and financial support for apprenticeships and students in need (OECD, 2021[62]), (OECD, 2022[63]).

Thailand has experience with hiring subsidies. One of the most recent measures was a 2022 job creation programme that targeted people who recently completed tertiary education or who were recently laid off. The programme intends to provide subsidies for hiring around 70,000 people in the Bio-Circular-Green sector, allocating 0.02% of GDP. Eligible projects, mostly community-based, received a grant for three months and are supposed to provide on-the-job training. Going forward, the case for hiring subsidies may weaken as the economy recovers and young people with good qualifications would likely find jobs even without these subsidies.

On the other hand, a strong case remains for strengthening a well-balanced set of active labour market policies (ALMPs), including professional training for young people in unemployment (Thasanabanchong, 2020[64]). Various training programmes have targeted unemployed people, such as a 30-hour training package for workers in selected industries, SMEs and unemployed, with a focus on specific technologies (OECD, 2020[1]).

Professional training can be combined with job-search assistance, career guidance and counselling. This has been the role of the Public Employment Offices, which have been progressively strengthened over the years. In 2015, 87 Smart Job Centres were launched nationwide to provide online one-stop shop services to jobseekers. During the pandemic, the government launched another online platform, “Thai Me Ngaan Tham”, and actively promoted these online services to reach out to people in need, including young people. Still, participation in career guidance programmes declined between 2019 and 2021, while the number of unemployed people aged 15-24 increased by one third. Although the avoidance of physical contact may explain part of this, the number may nonetheless hint at room for improvement in the services provided. Especially during the pandemic, a number of countries scaled up resources for labour market services to address rising demand for such services (OECD, 2021[65]). The Thai government decided to continue the Thai Me Ngaan Tham platform in collaboration with private placement firms, which is likely to help job seekers, especially for young people.

Active outreach to the young unemployed should become a priority. Previous studies suggest that only half of young unemployed Thais receive career guidance services, as many young people in need are not aware of these government services (UNICEF, 2022[66]). Cooperation with local civil society organisations that maintain close links with young people in need, particularly in rural areas, may be an effective complement (OECD, 2021[67]) (OECD, 2021[68]). The current collaboration is often ad-hoc and temporary, and career training programmes by Public Employment Offices are mostly provided in urban areas (UNICEF, 2022[66]). Belgium, for example, launched an employment support programme in 2020, in collaboration with private partners that provide a range of services from outreach to personalised guidance and follow-up support after labour market integration, among others (European Commission, 2021[69]).

In addition, reaching out to young people while they are still in school could also raise awareness of the services offered by Public Employment Offices. Previous studies comprising several OECD countries suggest that career guidance would be more effective if started before the age of 15 (OECD, 2021[70]). In the United Kingdom, the government launched a programme to connect workplace volunteers and schools in 2012, achieving more than 2.5 million interactions (OECD, 2021[70]). In Thailand, the Ministry of Labour encourages to set up networks of volunteer experts to provide career information for students and teachers, which could be enhanced further with collaboration of employers.

The education system could do more to prepare young people for a successful start in the labour market. Thailand should increase both the spending efficiency and the budget for education to provide adequate resources for learning and human capital development. A high proportion of small schools with tiny class sizes, especially in primary schools, leads to an inefficient allocation of teachers, which is exacerbated by a lack of educational materials (World Bank, 2023[43]). Reallocating resources by merging some of the small schools over time could improve educational outcomes and competencies. More resources for vocational education and training, including with better IT infrastructure, can also help to build up digital skills which are facing growing demand.

Young people who are not employed are ultimately at risk of becoming detached from the labour market, working only informal jobs or becoming inactive altogether. Indeed, informal labour is highly prevalent among young workers, at 45% for the youth aged 15-24 against 51% of all age groups. In addition, the share of people aged 15-24 who are not in education, employment or training (NEET) has gradually increased over the past decade, surpassing the OECD average, although still lower than in some regional peers (Figure 1.29). In the context of a declining young population, getting young people engaged in the labour market and investing in their human capital will become increasingly relevant.

A number of countries have stepped up support to young NEETs. Korea has a comprehensive Vision Plan Programme targeting young NEETs (Osborne and Vandenberg, 2022[71]). The services provided by the programme are broad, stretching from academic and vocational training to psychosocial support and courses to develop social skills. The programme also includes family coaching and involves local communities. Previous studies suggest that the programme was able to reduce the probability of participants’ remaining in a NEET status by 7% (Park et al., 2020[72]). In Belgium, the government launched an employment support programme for NEETs in 2020, in collaboration with private partners that provide a range of services from outreach to personalised guidance and follow-up support after labour market integration, among others (European Commission, 2021[69]). Owing to the partnership with private intuitions, the programme can provide services without a time limit, which allows young people to continue the programme easily.

Overall, Thailand performs well in terms of the gender gap in the labour market. The labour force participation of women relative to men was 0.79 in 2021, higher than the OECD average of 0.77 and most regional peers, although lower than in Viet Nam where it stood at 0.88. Wage gaps for similar work are also relatively small (World Economic Forum, 2023[73]). However, despite recent improvements, women continue to be a minority in senior and middle management positions, accounting for 32% in total managers in 2021. Thailand could consider introducing a quota system for managers’ positions, which have proved to be effective in a number of OECD countries, including Germany and France (OECD, 2020[74]).

Bringing more people into formal jobs will also require putting an end to discriminatory hiring practices based on age. Biases against hiring workers of higher age are widely observed in a number of countries, including Thailand (OECD, 2019[75]) (Moroz et al., 2021[5]). Explicit references to age limits are not prohibited in job vacancy announcements in Thailand and are frequently used. Over the last decades, all OECD countries have prohibited old-age discrimination, following an ILO recommendation issued in 1980, originally submitted by Thailand. In the United States, for example, any job-related discrimination against people aged over 40 is forbidden. Some countries have complemented a prohibition with public awareness campaigns. In addition, a strong enforcement mechanism is crucial for success (OECD, 2019[75]). In the Netherlands, job vacancy advertisements are screened and employers announcing job vacancies with age limits are adverted with an official letter (OECD, 2014[76]).
