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

On August 21, 2026, Thailand’s Securities and Exchange Commission (SEC) published two consultation papers that would broaden regulated access to crypto assets while tightening custody standards. The first proposes a framework for establishing crypto exchange-traded funds (crypto ETFs) in Thailand. The second proposes enhanced qualification requirements for foreign digital asset custodians serving mutual funds and private funds that invest in digital assets. The proposals seek to expand regulated access to crypto assets while strengthening custody, governance, disclosure, and investor protection, and they affect fund managers, trustees, and licensed digital asset operators. Comments on both papers are due by September 20, 2026, and the SEC expects the resulting rules to take effect later in 2026. Elevating Foreign Custodian Standards Under current rules in effect since January 16, 2025, mutual funds and private funds investing in digital assets may use foreign custodians that meet qualifications similar to those set for domestic digital asset business operators. The SEC now proposes that foreign digital asset custodians satisfy two cumulative requirements: Compliance with the existing baseline qualifications: demonstrated expertise, robust cybersecurity measures, segregation of client assets, controls preventing unauthorized asset transfers, and sound financial standing. Supervision by a regulator that is either (1) an IOSCO Signatory A member under the Multilateral Memorandum of Understanding, the international arrangement through which securities regulators share information and cooperate on enforcement, or (2) a regulator in a jurisdiction that the Thai SEC designates as having adequate supervisory and investor protection standards. The SEC is initially considering 11 jurisdictions for the approved-country list: France, Germany, Hong Kong SAR, Ireland, Japan, Liechtenstein, Luxembourg, Malaysia, Singapore, South Korea, and the United States. The SEC may expand this list over time based on its assessment of other jurisdictions’ regulatory frameworks governing custodian licensing, asset segregation, secure custody practices, client rights in insolvency,

Carbon markets have moved to the forefront of corporate and regulatory agendas as global attention to climate change and sustainability intensifies. Worldwide, many jurisdictions—including Thailand—are finding carbon markets to be promising tools in their efforts to combat climate-warming emissions and accelerate their net-zero pathways and sustainability commitments. According to the Thailand Greenhouse Gas Management Organization’s (TGO) 2025 Voluntary Carbon Market Survey, approximately 3.29 million tonnes of CO₂ equivalent (tCO₂eq) were traded under Thailand’s domestic standard between 2020 and 2024 with a cumulative market value of approximately THB 314.5 million (approximately USD 9.43 million), and 524 projects had been registered under the Thailand Voluntary Emission Reduction Program (T-VER) framework. Carbon Credits in Thailand Thailand’s carbon credit regime is, at present, entirely voluntary. There is not yet any obligation for businesses to purchase or retire carbon credits, although this may change once the draft Climate Change Act is enacted. The draft Climate Change Act, which is currently undergoing legal review before submission to Parliament, is expected to introduce a mandatory emissions trading system (ETS), under which  legal entities in designated sectors will be allocated emissions allowances and will be required to surrender sufficient allowances to cover their verified emissions, with penalties for shortfalls. Rather than imposing a blanket obligation on all businesses to purchase or retire carbon credits, the draft act is expected to allow ETS-covered entities to use eligible carbon credits (for example, those certified under T-VER) to meet only a limited, capped portion of their compliance obligation, with the applicable cap and eligibility criteria to be set out in subordinate regulations and the relevant allocation plan. The principal domestic framework for carbon credits is the T-VER, administered by the TGO. While some project developers in Thailand also operate under international standards such as Verified Carbon Standard or the Gold
