The Thailand Securities and Exchange Commission has opened a public consultation on proposed principles to amend the Securities and Exchange Act B.E. 2535 (1992) to strengthen supervisory legal measures and make law enforcement and examinations more timely and effective. The package would broaden oversight of certain securities transactions, add new reporting duties, and give the regulator stronger tools to intervene where conduct may harm investors or the public interest. The proposals would impose duties on investors who sell securities without having the securities in their possession, with those transactions required to comply with rules set by the Capital Market Supervisory Board. Foreign service providers would also have to report information on the ultimate beneficial owners of securities. Separate reporting obligations would apply to the creation of significant encumbrances over securities, including pledges for margin accounts, the use of shares as collateral for borrowing without transfer of the shares, and pledges of shares registered with Thailand Securities Depository Co., Ltd. The draft principles would also allow temporary suspension of transactions that may involve unfair advantage or cause serious damage to investors or the public interest, clarify the revocation of seizure or attachment of assets of juristic persons, authorize other persons to conduct examinations on the SEC's behalf, and revise penalty and fine settlement provisions. The public hearing runs until 24 July 2026.
