Social Security Funds 3 Trillion Baht May Collapse Without Reform: Private Sector Views and TDRI Proposals

Although the Social Security board election concluded on 11 Oct 2026 GMT+7, insured members are still awaiting official certification of results from the Social Security Office (SSO), Ministry of Labor. However, many agree that reform of the Social Security Fund must begin immediately to avoid insolvency within the next 20 to 30 years, as numerous parties have warned.

Thairath Money aims to summarize all issues and private sector viewpoints on how to adjust this 3 trillion baht fund to survive and ensure sufficient resources to support insured members in the long term.

What commitments has the Social Security Fund made?

The Social Security Fund was established in 1990, around 30 years ago, before the introduction of universal health coverage or the Gold Card scheme. At that time, contributors or insured persons received two key benefits considered valuable then: medical treatment at both public and private hospitals without bearing the full cost, and life protection benefits such as unemployment allowance, child welfare, and a choice of lump-sum or pension retirement payments.

(SSO benefits cover seven cases: sickness, childbirth, disability, death, child welfare, unemployment, and old age.)

After the introduction of the Gold Card, often called free healthcare by many, Social Security medical coverage decreased, such as exclusion of certain diseases and treatments like laparoscopic surgery requiring out-of-pocket payment. Some seriously ill patients have had to waive Social Security rights to use the Gold Card benefits instead.

Currently, insured members question the overlap of medical rights despite paying contributions, and more importantly, rumors that the fund may run out of money and risk bankruptcy within 20-30 years. Although the SSO's investment portfolio now exceeds 3 trillion baht, growing partly due to increased contributors, the average 35-year return is only 1.44% annually.

Thailand is becoming an aging society with more retirees, and fewer working-age contributors paying into the fund. Data from Chakorn Lertnit, Senior Researcher at the Thailand Development Research Institute (TDRI), indicates that the number of beneficiaries, especially pensioners, will grow significantly faster than insured contributors. From 1.9 million pensioners in 2030, the figure is projected to reach 8.7 million by 2053, while the number of contributors grows more slowly and then stabilizes around 15–16 million, reflecting that fund expenses will outpace income.

"Income growth has continuously lagged behind expenses. With a fixed 6% contribution rate and limited growth in contributors, even a 1.5% annual wage increase adjusted for inflation cannot offset the faster growth of expenditures. The result is a negative net cash flow and the fund must draw down reserves until they eventually deplete to zero," Chakorn explained.

TDRI analyzed factors including declining birth rates, rising inflation, Social Security expenses, and current management conditions, finding that net cash flow will turn negative around 2037 and reserves will be exhausted between 2050 and 2058, assuming investment returns of 2–6% per year.

In summary, without structural adjustments, the Social Security system will enter a structural deficit within 20–30 years. This projection assumes no behavioral changes after 2037, such as beneficiaries switching from pensions to lump sums or new workers opting out of the system.

This has led insured members to question how their current contributions are managed to ensure future payout commitments.

What is the investment portfolio like, and how have returns performed?

To assess whether the fund can pay benefits to the current 24.82 million insured persons, one must start with the SSO's assets. As of 30 Sep 2026 GMT+7, the Social Security Fund's investments totaled 3.035 trillion baht, divided into

• accumulated contributions from employers, employees, and government of 1.787 trillion baht, or 58.90%,
• and accumulated investment returns of 1.247 trillion baht, or 41.10%.

The investment portfolio is broadly allocated with up to 60% in high-security securities and no more than 40% in riskier assets, detailed as follows:

• Thai equities (e.g., stocks) at 208.991 billion baht, representing 6.88%,
• unrated foreign bonds at 74.895 billion baht, or 2.47%,
• state enterprise bonds without Ministry of Finance guarantees at 1.928 billion baht, or 0.06%,
• investment grade foreign bonds at 666.058 billion baht, or 21.95%,
• rated private bonds or securitized debt at 60.872 billion baht, or 2.00%,
• foreign equities at 514.906 billion baht, or 16.97%,
• real estate and infrastructure investment units at 127.672 billion baht, or 4.21%.

Overall, the fund holds 69.41% in high-security securities and 30.59% in risk assets, with 55.61% invested domestically and 44.39% abroad. In the first nine months of 2026, from this 3 trillion baht portfolio, the Social Security Fund generated returns of 77.069 billion baht, about 2.539%.

Looking further back, data from the Progressive Social Security Group indicates the fund's accumulated profits of 1.1 trillion baht have averaged only 1.44% annual growth over 35 years, making it difficult to keep pace with long-term inflation.

Chakorn's TDRI report also notes that although the fund manages trillion-baht assets, its average 20-year return has been below 5% annually, relatively low compared to other large funds and current market opportunities. Despite policy constraints and a conservative investment framework, these results raise questions about the fund's asset management capacity and efficiency.

What factors are essential to ensure survival?

For the Social Security Fund to remain viable long-term and have sufficient money to pay promised benefits, serious reforms are needed. Pichet Jiaramaneethaweesin, former president of the Actuarial Society of Thailand, cites four factors critical to sustainable fund operation:

• Assessing the fund's expenses using statistical data, considering all types of expenditures, such as retirement payments, pension duration, and age-specific medical statistics,
• the Time Value of Money principle, as money today and money in the future are not equally valuable, where better investment management and higher average annual returns help fund growth, but investment management must balance return, risk, liquidity, and the timeframe of fund disbursements,
• the relationship between contributions and benefits, which should be appropriately aligned. Although Social Security emphasizes risk pooling and mutual support, benefit entitlements must fit contribution levels and available resources, especially long-term benefits like pensions requiring comprehensive consideration.
• Long-term balance, where fund inflows and outflows need not match annually but must be continually assessed to ensure assets and investment returns can meet benefit obligations decades ahead.

"Sustainable fund management means striving to balance current income with future obligations amid uncertainty. Maintaining this balance is fundamental for Social Security to reliably support insured members in the long term," Pichet said.

Meanwhile, TDRI offers reform proposals for Social Security, divided into three main points:

• Internal organizational improvements focusing first on building trust before balancing the fund, through transparency and good governance, such as criteria for board member selection based on expertise rather than political positions, and clear, accessible disclosure of investments and returns, responding to societal demands in Thailand.
• Medium-term stability via parameter adjustments, such as gradually increasing contribution rates, raising retirement age consistent with rising life expectancy, and reviewing pension formulas as working years lengthen.
  TDRI’s models show that increasing contribution rates or investment returns alone may buy time but cannot solve structural issues. Burdens must be fairly shared between generations to avoid excessive pressure on younger cohorts and avoid abrupt changes that shock the economy.
• System-wide rethinking, focusing on two benefits: 1) health insurance—whether to maintain Social Security's health coverage separately or integrate it with universal health coverage, and 2) pensions—whether to keep the current system or develop alternatives like voluntary or mandatory savings schemes seen abroad, while considering national system coherence and public comprehension.

Overall, the data indicate that Social Security requires not just adjustments but fundamental structural reform to find balance and ensure long-term sustainability, based on information from the SSO and TDRI.
