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.
