Thailand Opens Securities, Derivatives, and Intergroup Financing to Foreign Businesses

Certain securities, derivatives, and treasury activities in Thailand were opened to foreign investors when Thailand’s Ministry of Commerce published two new ministerial regulations in the Government Gazette on August 28, 2026. The regulations significantly broaden the service activities that foreign-owned businesses may conduct without a license or certificate under the Foreign Business Act B.E. 2542, as amended (FBA).

Securities and Derivatives Business Exemptions

Prior to the issuance of these ministerial regulations, the exemptions covered (1) securities brokerage and derivatives brokerage with their only underlying assets being agricultural commodities, financial instruments, and securities; and (2) dealers, advisers, and fund managers conducting derivatives business under Thailand’s derivatives laws.

The ministerial regulations provide broader exemptions. In addition to derivatives under the laws on derivatives as before, the following two major categories are provided:

  • Derivatives whose underlying assets or variables fall outside the scope of Thailand’s laws on derivatives. This addresses a gap in the previous framework, which did not comprehensively exempt derivatives tied to nonregulated underlying assets or variables, such as certain commodities. Foreign brokers, advisors, and fund managers can now facilitate a broader range of hedging and risk management instruments without triggering FBA licensing requirements.
  • Derivatives traded outside a derivatives exchange, or over the counter (OTC), whose payments are calculated by reference to foreign exchange rates or interest rates. This removes an FBA licensing barrier for foreign providers of widely used OTC hedging products, broadening the solutions available to importers and exporters managing currency exposure and to borrowers seeking greater certainty over financing costs.

The ministerial regulations also exempt brokers and agents handling transactions involving either of these two derivatives categories.

For securities businesses, the ministerial regulations add exemptions for margin loans used to purchase securities and for securities repurchase transactions. These additions clarify whether such activities qualify as exempt brokerage businesses under the FBA.

New Exemption for Guarantees Between Related Parties

The ministerial regulations also introduce an exemption for the provision of guarantees between related companies, partnerships, directors, or managing partners in Thailand. Previously, FBA exemptions for domestic intragroup financial support focused on loans. Multinational groups therefore had to obtain an FBA license, arrange parent or affiliate guarantees through a properly licensed Thai entity, or adopt more complex alternative structures. Removing the FBA licensing requirement allows qualifying groups to use parent or affiliate guarantees more efficiently and provides greater flexibility in structuring financing and credit support in Thailand.

To qualify, a guarantee must be provided between parties that meet specified relationship tests based on common ownership or management. Qualifying relationships may involve common majority shareholders or significant overlapping shareholdings. Because the tests vary with the relationship and corporate structure, each arrangement should be assessed individually.

Cross-border financing to affiliates remains restricted and should be assessed carefully before implementation.

Implications for Foreign Businesses

For qualifying foreign businesses, the ministerial regulations can reduce licensing costs and lead times and make previously cumbersome products or arrangements commercially viable. Businesses already conducting newly exempt activities should confirm that they meet the applicable conditions and assess whether they still need existing licenses or certificates for other activities. Businesses planning new operations should also consider whether their group structures and transaction terms can be designed from the outset to take advantage of the exemptions, particularly for intragroup guarantees and expanded derivatives offerings.

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. While the core criteria

Thailand’s Ministry of Finance and Securities and Exchange Commission (SEC) have issued regulations broadening the criteria for determining who qualifies as a “major shareholder” of licensed securities and digital asset business operators. Under relevant SEC regulations, major shareholders of a regulated entity must obtain regulatory approval and undergo screening by the SEC. The revised framework introduces both shareholding-based and control-based tests to determine which shareholders require regulatory approval for a wider range of indirect ownership structures and de facto control. The Ministry of Finance notification took effect on February 21, 2026, while the SEC’s clarifying rules took effect on March 4, 2026. These changes aim to enhance transparency around beneficial ownership and strengthen regulatory oversight of entities operating in Thailand’s capital markets. Expanded Definition Under the revised framework, a “major shareholder” now includes persons who directly or indirectly hold more than 10% of the voting rights in a regulated company, as well as persons who exercise control over the regulated company or its shares. This system of two separate tests, based on both shareholding and control, differs from the prior regime, which focused primarily on shareholding thresholds and applied a more limited method for determining indirect shareholdings. The two tests (detailed below) operate independently of each other, and any person identified by either of the tests will be deemed a major shareholder. Shareholding-Based Test Broadens Indirect Ownership Attribution For the shareholding-based test, the SEC recognizes two existing methods for identifying indirect ownership, together with a new proportional attribution method. Any person captured under these methods, which are described below, will be regarded as a major shareholder of the regulated company and must obtain SEC approval as a major shareholder. First, the existing framework continues to apply to both first-tier and chain ownership structures. Approval is required for (1) first-tier

Thailand’s Securities and Exchange Commission (SEC) has overhauled its approach to related-party transactions (RPTs) by issuing new rules that simplify approval processes while expanding oversight. Capital Market Supervisory Board Notification No. TorJor. 46/2568 will replace the longstanding Notification No. TorJor. 21/2551, which has governed RPT compliance for over a decade. The new regulation takes effect on July 1, 2026. Any RPT matters approved by a company’s board of directors or approved for shareholders’ approval before that date remain subject to Notification No. TorJor. 21/2551. The new RPT rules will introduce significant changes that market participants should carefully consider. Consolidated Definitions Under the previous framework, key definitions relevant to RPT compliance were dispersed across multiple sources, including SEC notifications, Stock Exchange of Thailand (SET) regulations, and provisions of the Securities and Exchange Act (before amendments). The new regulation consolidates these definitions into a single notification. Concepts such as “related party” and “connected person,” as well as relevant transaction categories, are now more systematically organized and written in greater detail. The SET has yet to issue corresponding regulations, which should include more detailed related disclosure requirements. Unified Threshold and Mandatory Board Approval The most significant change under the new regulation is the elimination of the multitiered approval framework based on transaction type. Instead of various categories, transactions are now classified as either (1) financial assistance provided to related persons, or (2) other RPTs in order to determine the level of corporate approvals and disclosures for each transaction size in these categories, but the concept remains the same. Under the previous regulation, RPTs were divided into small, medium, and large transactions, with differing approval requirements. The new regulation effectively merges the small and medium categories. As a result, all RPTs must now be approved by the board of directors as a baseline
