Thailand Capital Market Reforms 2026-2028: TISA, Dual-Class Shares, and Crypto ETFs Explained

The Thailand Securities and Exchange Commission (SEC) has embarked on a comprehensive reform of the nation's capital market infrastructure—a move that could unlock up to 1 trillion baht in foreign inflows and fundamentally reshape how both local savers and international investors approach the Thai equity and bond markets.

Why This Matters:

• TISA launches July 1, 2026: Tax-deductible savings accounts offering up to 800,000 baht in annual deductions, directly impacting retirement planning for Thai taxpayers.

• Crypto ETFs arrive Q3 2026: Thailand will join the ranks of markets offering regulated cryptocurrency exchange-traded funds, expanding investment options.

• Foreign money is returning: After 16.54 billion baht in net foreign buying on a single day in February, institutional confidence is climbing.

• Private trust framework targets wealth migration: New tax structures could position Thailand as a regional asset management hub, rivaling Singapore.

The Push to Modernize: What's Driving Thailand's Urgency

Thailand's Stock Exchange of Thailand (SET) closed at 1,325.62 points at the end of January, up 5.2% from the prior year. By late April, the SET50 index had climbed 25.09% year-over-year to 972 points. Yet beneath these gains lies a sobering reality: Thai equities were among the worst global performers in 2025, dragged down by political uncertainty, sluggish GDP growth, elevated household debt, and liquidity concentrated in a handful of large-cap names.

Global investors had been scaling back exposure, skeptical that cheap valuations alone could justify entry without structural reforms. The turning point came in February, when election results signaled political stability and the formation of a durable government. Foreign sentiment pivoted sharply: the SET surged over 3% on February 9, with turnover exceeding 100 billion baht for the first time in more than a year.

Now, regulators are racing to capitalize on that momentum with a coordinated reform package spanning 2026 to 2028, designed to restore trust, deepen liquidity, and diversify the investor base.

The Flagship Initiative: Thailand Individual Savings Account (TISA)

At the heart of the government's "Quick Big Win" policy is TISA, a long-term savings vehicle launching July 1, 2026, built to channel household wealth into domestic equities and mutual funds. This is not a marginal tweak—it's a systemic attempt to address Thailand's demographic reality. The country officially became an aging society in 2024 and is on track to be super-aged by 2033.

How TISA Works:

• Open to Thai resident individuals only (one account per taxpayer). Note: 'Thai resident' refers to tax residency status, not citizenship. Expatriates who qualify as tax residents of Thailand should verify eligibility with the Revenue Department.

• Combined tax deductions up to 800,000 baht annually, including contributions to Super Savings Funds (SSF), Retirement Mutual Funds (RMF), and Thai ESG Funds (TESG).

• Taxpayers earning under 1.5 million baht qualify for deductions up to 1.3 times their investment; higher earners face a 0.7 times cap.

• A 1.2x ESG multiplier applies to eligible green investments.

• Tax-exempt gains after a specified holding period.

• Administered through asset management companies, commercial banks, or brokerages.

How to Access TISA: Accounts can be opened through licensed asset management companies, commercial banks, or securities brokers starting July 1, 2026. Taxpayers should consult with their financial institution before the launch date to understand eligible investment products and documentation requirements.

The Association of Investment Management Companies (AIMC) has pushed for systematic investment strategies—dollar-cost averaging (DCA) and dollar-cost forward (DCF)—to be embedded in TISA offerings, making disciplined, long-term investing accessible to retail participants.

For residents, TISA represents a direct opportunity to reduce taxable income while building retirement savings. For the market, it's a potential liquidity injection that could rival the impact of provident fund reforms.

Dual-Class Shares: Breaking the "One Share, One Vote" Rule

Thailand has long operated under the Public Limited Company Act of B.E. 2535 (1992), which mandates a strict "one share, one vote" principle. This has put the SET at a disadvantage compared to markets like Singapore, Hong Kong, and even Vietnam, where dual-class share structures allow founders to retain control while raising public capital.

The Reform:

• Legislative amendments to the Public Limited Company Act, Securities and Exchange Act, and SET regulations are in progress.

• The changes would permit shares with differential voting rights, allowing more than one vote per share for certain classes.

• Target companies: High-growth family businesses, tech startups, and new economy firms that prioritize strategic control.

• Expected benefit: Increased free float, greater foreign institutional participation, and a deeper pipeline of quality IPOs.

Proposals were submitted to the Committee for Urgent Legal Reform, with initial reports in March 2025 suggesting implementation within four months. As of early May 2026, the legislative timeline remains fluid, but the intent is clear: to make Thai listings competitive with regional peers.

Streamlining IPOs and Cross-Listings

Both the SEC and SET have committed to cutting red tape around public offerings. Current processes are seen as slow and prescriptive, deterring foreign companies and high-potential startups from choosing Thailand as a listing venue.

Key Measures:

• Streamlined IPO approval timelines, targeting processes under 30 days (a standard Vietnam is also pursuing).

• Easing regulatory barriers to attract cross-listings of high-potential foreign firms.

• Disclosure-based regime: Moving away from prescriptive criteria toward a framework emphasizing transparency and investor education.

The SET's 2026-2028 strategy, titled "The Trusted Gateway to Inclusive Opportunities," aims to attract new economy companies, SMEs, startups, and foreign enterprises. The exchange is collaborating with regulators to modernize listing standards while maintaining robust governance.

Digital Assets: Crypto ETFs and Tokenization

Thailand is positioning itself at the intersection of traditional finance and digital assets. The SEC's crypto ETF framework is scheduled for implementation in Q3 2026, with an emphasis on risk disclosure and investor protection.

What's Coming:

• Trust-form crypto ETFs, allowing regulated exposure to digital currencies through familiar investment vehicles.

• Tokenization support: Developing digital assets as a full investment class, with regulatory clarity for issuers and investors.

• "Speed Bump" measures: Already in effect, the SEC has frozen over 10,000 suspicious cryptocurrency accounts. Transfers of 50,000 baht or more face a 24-hour transaction lock and additional KYC checks.

This dual approach—innovation paired with enforcement—aims to capture the upside of digital finance while curbing the "grey capital" and mule account networks that have plagued regional markets.

Private Trust Framework: Competing with Singapore

Perhaps the most ambitious reform is the proposed private trust framework, designed to attract global wealth and establish Thailand as a regional asset management hub. Drawing inspiration from Singapore's model, the initiative includes:

• Legal structure for private trusts, offering estate planning and wealth preservation tools.

• Competitive tax incentives tied to domestic investment: foreign investors must allocate at least 10% of assets to Thai capital markets.

• Projected impact: Estimates suggest the framework could unlock up to 1 trillion baht in foreign inflows over the next two years.

For high-net-worth individuals and family offices, this could position Thailand as a viable alternative to Singapore, particularly if paired with the country's lower cost of living and growing expatriate infrastructure.

What This Means for Residents

For Thai taxpayers: TISA offers a tangible, immediate benefit—up to 800,000 baht in annual tax deductions. If you're already contributing to RMF or SSF, TISA is a natural extension. The ESG multiplier adds an incentive for aligning savings with sustainable investments.

For expatriates and long-term residents: The broader reforms—crypto ETFs, dual-class IPOs, and the private trust framework—expand the investment universe. If you hold assets in Thailand or are considering a trust structure for estate planning, the new private trust rules could offer significant flexibility. Additionally, expatriates who meet Thailand's tax residency requirements may qualify for TISA benefits and should explore eligibility with their financial advisor.

For investors: The return of foreign capital, combined with structural reforms, suggests improved liquidity and diversification. However, caution is warranted: the SET remains vulnerable to external shocks, concentrated liquidity in large caps, and slower mid-cap trading. The prohibition of short selling outside the SET100 index is designed to reduce volatility, but it also signals lingering concerns about thin order books.

Bond Market and Corporate Governance Overhaul

Beyond equities, the SEC has established a dedicated taskforce to strengthen bond market supervision. New rules allow firms that renegotiate or extend repayment terms without default to continue issuing debt, provided they fully disclose such history. This transparency-first approach aims to rebuild confidence after past scandals.

On the corporate governance front, Thailand is tightening oversight of nominee shareholding structures, which have historically been used to bypass foreign ownership restrictions. Auditors face stricter scrutiny, and legal proceedings for securities violations are being expedited.

Anti-Fraud and Investor Protection

The "Connect the Dots" task force integrates identity, behavior, and financial data to dismantle illicit mule account networks and combat sophisticated investment scams. Enhanced Know Your Customer (KYC) protocols and mandatory reporting of suspicious transactions are now standard across securities firms.

The SEC's enforcement posture is unambiguous: it has frozen over 10,000 crypto accounts and is expanding oversight of beneficial owners. For retail investors, this means a safer trading environment, albeit with more friction during onboarding and large transactions.

Regional Competition: Singapore, Vietnam, and Thailand

Singapore remains the gold standard: the Monetary Authority of Singapore has expanded its Equity Market Development Programme (EQDP) to S$6.5 billion, offering direct capital to asset managers focused on Singaporean equities. The Global Listing Board, a partnership with Nasdaq, facilitates dual listings with streamlined documentation. Singapore's mature infrastructure, advanced fintech ecosystem, and robust legal framework give it a structural edge.

Vietnam's Recent Progress:

• Achieved FTSE Russell's "Secondary Emerging Market" upgrade (expected September 2026), projected to unlock US$3-5 billion in near-term inflows and up to US$25 billion by 2030.

• Removed pre-funding requirements for foreign investors and eased foreign ownership limits, directly addressing barriers that had constrained institutional participation.

• Deployed the KRX trading system and is targeting IPO timelines under 30 days.

Thailand's Competitive Advantages:

• TISA is unique in the region, offering a direct channel for household savings into the market—something neither Singapore nor Vietnam has prioritized to the same degree.

• Advanced anti-fraud measures and corporate governance reforms exceed those in Vietnam.

• The private trust framework, if implemented effectively, could carve out a niche for Thailand in wealth management, though it will face fierce competition from Singapore's entrenched ecosystem.

The Execution Challenge: Thailand's competitive position hinges on execution speed. Its IPO processes remain slower than both Singapore and Vietnam, making timely implementation of legislative reforms critical to attracting capital and IPO candidates.

The Road Ahead

The Thailand SEC and SET have laid out an ambitious agenda through 2028. Success will depend on legislative follow-through (particularly on dual-class shares), investor uptake of TISA, and the regulatory clarity surrounding crypto ETFs and tokenization.

For residents, the reforms represent a notable coordination of government policy and market incentives. The combination of tax-advantaged savings, expanded investment products, and stricter enforcement creates a more accessible and trustworthy capital market. For international investors, Thailand is signaling that it is serious about competing for capital—but the proof will be in the execution, not the announcements.
