Thai SEC Proposes Expanding Oversight to Cover Funding Sources of Capital Markets Operators

Subscribe to Updates

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 within the 180-day window established by the notification of the Ministry of Finance. This is particularly relevant for structures involving back-to-back financings, guarantees, or other derivative or structured arrangements that result in a person being, or effectively being, a source of funding to a major shareholder of the licensed operator.

While the proposed amendment does not specify how and to what extent the SEC will review the funding sources and related documentation, licensed operators should conduct detailed due diligence on funding arrangements and counterparties, gather documentation, and potentially renegotiate or restructure arrangements that inadvertently create approval obligations.

Operators whose shareholders rely on ordinary margin credit, repurchase agreements, or loans from Thai banks or BCBS-jurisdiction foreign banks can take comfort in the carve-outs, but the burden of proof lies with the operator. Any funding instrument that resembles equity economically, even if formally documented as debt, may require approval.

The scope of “source of funding” under the proposed amendment is notably broad and may require more detailed definition or interpretation from the SEC. Operators with concerns about definitional ambiguity, such as whether certain indirect funding arrangements fall within the expanded scope, should consider raising these issues during the public hearing stage. The SEC may lessen this ambiguity by issuing supplementary guidance that clarifies:

  • The types of arrangements that constitute indirect funding,
  • Thresholds or materiality standards for triggering approval requirements, and
  • Broader safe harbors for common commercial financing structures that are not intended to confer economic ownership, beyond the specific exemptions currently prescribed in the hearing.

Next Steps

The SEC has compressed the public hearing period to 15 days because the issue is urgent and operators need adequate lead time to comply within the broader 180-day transitional deadline. Operators may submit comments on the proposed expansion by April 22, 2026, and should simultaneously begin internal audits of shareholder funding structures and engage with lenders and counterparties to confirm exemption eligibility or prepare approval filings, as appropriate.

Early engagement with the SEC may help clarify ambiguous arrangements before the rules take effect. Operators can contact us for more information or assistance with submitting comments on their behalf.

The Stock Exchange of Thailand (SET) has issued new oversight and disclosure rules, effective July 1, 2026, overhauling the previous requirements. The reforms apply to listed companies, REITs, and property and infrastructure funds, and aim to enhance transparency, align with international standards, and ensure timely investor information. The key changes and practical implications are highlighted below. Major Shareholder Reporting When a shareholding change reaching or crossing 5% or any subsequent multiple of 5% is reported under section 246 of the Securities and Exchange Act or a tender offer is completed (except for voluntary delisting), listed companies must disclose an updated shareholder list for the month in which the triggering event occurred. The list must be compiled within five business days after month-end and disclosed within 14 days thereafter. Noncompliance will trigger a “notice pending” (NP) sign. This replaces the previous requirement to disclose shareholder lists only at annual general meetings or on record dates. Companies should coordinate with their share registrars to meet the new event-driven timelines. New Financial and Internal Control Disclosures The new rules require disclosure of material impairment, expected credit losses, and unreturned business deposits when these reach specified thresholds. Companies must also disclose events or indicators that may materially affect their internal control systems. Boards and audit committees should expect to escalate accounting and internal-control issues earlier, as these matters may now trigger standalone SET disclosure obligations—not just financial statement treatment. Backdoor Listing With the Securities and Exchange Commission’s regulation on material transactions (MTs) taking effect on July 1, 2026, and now serving as the primary, standalone framework governing acquisitions and disposals, the SET needed to issue a standalone rule on backdoor listing matters. These matters had been covered by a previous regulation on MTs issued by the SET. The key differences between the SET’s

Thailand’s Securities and Exchange Commission (SEC) is seeking public input on significant amendments to the Securities and Exchange Act B.E. 2535 (1992) that would address recurring market abuses and eroded investor confidence observed by the SEC. Published on June 24, 2026, the consultation document targets share-pledging disclosure failures, hidden beneficial ownership, and fraudulent transactions by listed companies, all of which are issues that have threatened share prices and market stability across the Thai capital markets. Comments on the proposals are due by July 24, 2026. Mandatory Disclosure of Short Sales and Share Pledges The draft amendments introduce new reporting obligations for both short sales and share pledges. Persons who sell listed securities without having such securities in their possession (“short sales”) must comply with rules prescribed by the Capital Market Supervisory Board, ensuring standardized practices and preventing risks from such transactions. Major shareholders who pledge or encumber their shares in significant amounts must report those arrangements to the SEC, which may then disclose the information to the public. These amendments directly respond to recent market abuses, including short selling without proper safeguards and instances where directors or major shareholders have pledged large share blocks without disclosure to investors, only to have those shares forcibly sold when collateral was called, causing dramatic share price declines and disrupting ownership structures and market stability. Reportable transactions for share pledges include the following: Shares used as margin account collateral Shares pledged as loan security, with immediate transfer upon default Shares formally pledged under the Civil and Commercial Code or registered with the Thailand Securities Depository Failure to report share pledges triggers criminal penalties, as does failure to comply with short sale requirements. By requiring advance disclosure and standardized short sale procedures, the SEC aims to enable investors to assess ownership stability and default

Thailand’s Securities and Exchange Commission (SEC) has released a detailed draft notification expanding its oversight to cover the funding sources behind major shareholdings in licensed securities and digital asset business operators. Published on June 8, 2026, as Public Hearing Document No. 30/2569, the draft builds on funding-source principles introduced in an April hearing and on recently amended Ministry of Finance notifications issued in February 2026 that broadened the definition of major shareholder of licensed securities and digital asset business operators. A public comment period on the draft closes on June 23, 2026. An earlier version of the SEC’s proposal brought the issue of funding behind significant shareholdings within the SEC’s regulatory perimeter, signaling intent to look beyond shareholding to the persons and capital ultimately financing major shareholdings in licensed securities and digital asset business operators. The concern is that control may be exercised through financing arrangements rather than through equity ownership alone. The draft notification advances that initiative into a more detailed regulatory framework, as summarized below. Expanded Definition Captures Funding Sources Throughout Ownership Chains The draft regulation introduces a “material funding source” concept. A material funding source is the principal capital that enables a major shareholder to acquire its shareholding, without which the shareholding could not be obtained. Under the proposed rules, any person who provides such funding, whether directly to the major shareholder or indirectly through any tier of the ownership chain above the operator, is deemed a controller subject to SEC approval. The draft also captures any person acting as a conduit or intermediary in facilitating financial assistance to a major shareholder, deeming each of these persons to be a material funding source and aggregating it into the same control group as the ultimate funding source. The definition covers not only cash loans and equity investments,

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
