Thailand Eases Stock Buybacks with Proposed Amendment: Listed Companies Expected to Jump In

Subscribe to Updates

In response to the Thai stock index’s decline and market volatility, Thailand’s Department of Business Development is proposing an amendment to the country’s treasury stock rules to ease the requirements for both the implementation and the disposal of shares, as they see this as a timely opportunity to optimize the use of treasury stock as a tool to support share prices and prevent them from falling below their fundamental value.

The rules governing treasury stock for public companies are set out in the Public Limited Companies Act B.E. 2535 (1992) (PLCA), its accompanying ministerial regulation, and the relevant rules issued by the Stock Exchange of Thailand (SET). The law permits share repurchases in two circumstances: (1) to buy back shares from dissenting shareholders following an amendment to the articles of association affecting voting or dividend rights, and (2) for financial management purposes when the company has retained earnings and excess liquidity—this second scenario is more common in the market. To satisfy the excess liquidity requirement, the company must primarily demonstrate the ability to meet its debt obligations within six months, have sufficient retained earnings, and ensure that the treasury stock implementation does not breach the SET’s free-float requirement.

The SET rules prescribe that the repurchase price must not exceed 115% of the five-day average closing price at the time of repurchase, and the disposal price must not be lower than 85% of this average closing price at the time of disposal. As for the timing, treasury shares must be held for at least three months and sold within three years; otherwise, the company must proceed with a capital reduction. There is also a six-month waiting period following the finishing or canceling of a previous share buyback before a company can start a new one.

The proposed amendment will ease these timings as follows:

  • A new share buyback program can commence immediately after the prior program ends, without the current six-month waiting period.
  • The resale period can be extended by up to three additional years beyond the current three-year limit, subject to shareholder approval and market prices remaining at or below the average buyback price. This should help ease concerns regarding disposal and avoid a capital reduction if prices do not recover.

The public hearing on the amendment concluded on April 10, 2025, and the market now awaits the official outcome and implementation of the proposed amendments. Listed companies that have already implemented share buybacks will likely be able to amend the disposal period to be in line with the new regulation following certain disclosure requirements.

After several years of policy discussion and continued efforts led by the Ministry of Commerce (MOC) to relax the list of reserved businesses under the Foreign Business Act B.E. 2542 (1999) (FBA), the reform process has now reached a significant milestone. On May 12, 2026, the Thai cabinet approved in principle two draft subordinate legislative instruments aimed at delisting certain reserved business activities under the FBA and reducing licensing requirements for foreign business operators. These developments signal a renewed and concrete effort by the government to modernize Thailand’s business regulatory framework in order to attract foreign investment and boost Thailand’s competitiveness in the global market. Nine Businesses Set for FBA Delisting Below is a list of the nine businesses that are being targeted for delisting from the FBA’s restrictions. A draft ministerial regulation would delist the first eight reserved businesses, while a royal decree has been drafted to delist the ninth business: Telecommunications services (Type 1 license only, covering operators without their own telecommunications infrastructure), under the supervision of the Office of the National Broadcasting and Telecommunications Commission. Treasury center services subject to the Foreign Exchange Control Act B.E. 2485 and under the supervision of the Bank of Thailand. Securities-collateralized lending, pursuant to the laws governing securities and exchange and derivatives regulated by the Securities and Exchange Commission. Agency, dealer, advisory, or fund management services relating to derivatives where the underlying assets fall outside the scope of the Derivatives Act B.E. 2546 (2003) Intra-group shared services, including administrative, human resources, and IT functions Intra-group domestic debt guarantee services Leasing of partial space for installation of financial service machines and automatic vending machines for employee use Petroleum drilling services Trading of agricultural product derivatives through a futures exchange, with physical delivery or receipt of agricultural products at a futures exchange–designated

Following Thailand’s recent expansion of the “major shareholder” definition for securities and digital asset businesses, the Securities and Exchange Commission (SEC) launched a public hearing on April 7, 2026, on expanding the major shareholder definition further to cover funding sources behind share acquisitions in licensed securities and digital asset business operators. The public hearing will remain open for 15 days from the launch date, after which the proposed expansion is expected to take effect promptly so that operators can comply with both the earlier and additional requirements within the 180-day transitional period under the earlier regulations. Funding Sources Captured Under Control-Based Test Under the draft rules, persons who fund direct or indirect major shareholders’ acquisition of shares in a licensed operator would be deemed “controlling persons” and subject to SEC approval as major shareholders. This extends beyond traditional lenders to include guarantors, counterparties to derivatives or structured products, and any arrangement that results in a person being, directly or indirectly, a source of funding to a major shareholder. The SEC proposes to exempt three categories of funding arrangements from approval: Loans from Thai licensed financial institutions or BCBS (Basel Committee on Banking Supervision)-jurisdiction foreign banks; Margin loans for securities trading under Thai securities law; and Repurchase agreements under Thai securities law. Exemptions for Funding Sources of Government-Linked Entities The consultation proposes to stop look-through beyond the level of certain government-linked shareholders, including, without limitation, ministries, departments, bureaus, public organizations, independent agencies, and certain state enterprises. The SEC reasons that these entities’ mandates, duties, and funding sources are already subject to government oversight and audit, presenting minimal ownership-structure risk. Practical Implications Licensed securities and digital asset business operators should begin mapping their funding chains under the expanded definition in preparation for filing approval applications for any newly captured funding providers

Thailand’s Securities and Exchange Commission (SEC) has established a comprehensive governance framework for the use of artificial intelligence and machine learning (AI/ML) in the capital markets. The framework provides guidance to capital market business operators on understanding the risks associated with AI/ML implementation and adopting appropriate practices to build public confidence in Thailand’s capital markets. While the guidelines are principle-based rather than prescriptive, they reflect the SEC’s expectations for responsible AI/ML governance and are likely to inform supervisory activities and industry standards going forward. Scope The framework applies to capital market business operators supervised by the SEC. This includes, for example, securities and derivatives firms, asset management companies, mutual fund and private fund managers, investment advisors and investment consultants (including robo-advisory service providers), derivatives intermediaries, and other licensed intermediaries and market operators in the Thai capital markets that deploy AI/ML in their operations. Core Principles of the Guidelines The framework is presented as a best-practice manual rather than prescriptive regulation, providing guidance that regulated entities may apply to their AI/ML governance and risk management as appropriate. While currently nonbinding, the guidelines signal the SEC’s expectations for the sector, particularly in relation to other binding SEC regulations such as those covering IT risk management and market conduct. The guidelines name four core principles for AI/ML deployment: Fairness: Design and develop AI/ML with consideration for fairness, equality, and social diversity to prevent discrimination against individuals or groups. Legal and ethical compliance: Ensure AI/ML use aligns with applicable laws, ethical standards, and organizational values and policies. Accountability: Establish clear responsibility—both internally and externally—for AI/ML activities and outcomes. Transparency: Provide adequate disclosure to users about AI/ML use, including explainability of decisions and traceability of activities. AI/ML Best Practices The guidelines prescribe best practices across four stages of the AI/ML lifecycle, as described below.

Thailand’s Securities and Exchange Commission (SEC) has broadened the definition of institutional investors, expanded the types of qualifying investments, and updated financial qualification thresholds for various investor categories through a revised notification on the definitions of institutional investors, ultra-high net worth investors, and high net worth investors. The amended framework, which came into force on March 1, 2026, adds digital asset business operators, investment planners, and investment consultants to the roster of entities recognized as institutional investors, and broadens the definition of investment to account for digital tokens. Expanded Definition of Institutional Investors Under the SEC’s revised notification, the category of institutional investors now expressly includes digital asset business operators licensed under the Royal Decree on Digital Asset Businesses B.E. 2561 (2018). This addition recognizes the growing role of digital asset platforms and service providers in Thailand’s investment ecosystem and aligns the regulatory treatment of digital markets with that of traditional markets. The definition of institutional investors now also encompasses investment planners and investment consultants approved by the SEC. Previously, only SEC-approved investment analysts held this status; the expansion covers a broader scope of professionals who possess comparable expertise and experience in evaluating investment opportunities. Broadened Investment Definition The revised framework now defines investment to mean direct or indirect investment in a wider range of assets beyond deposits. Specifically, the definition covers: Securities under the Securities and Exchange Act Derivatives under the Derivatives Act Investment tokens offered to the public Government-issued digital tokens (G-tokens) as specified in a separate SEC notification This expansion ensures that financial status assessments reflect the full spectrum of an investor’s holdings, including emerging digital assets. Updated Financial Qualification Thresholds The amended SEC notification also provides updated qualification thresholds for angel investors, ultra-high net worth investors, and high net worth investors.
