The proposed amendments to the SEA are intended to prescribe supervisory legal measures, enhance the efficiency of law enforcement and examination with a view to making such processes more timely and effective, and strengthen investor confidence in the Thai capital market for the benefit of the country’s overall economy. The proposed principles include:

    (1) Prescribing duties for investors who sell securities without having such securities in their possession, requiring such transactions to comply with the rules prescribed by the Capital Market Supervisory Board to ensure consistent standards and mitigate associated risks, and requiring foreign service providers to report information on the ultimate beneficial owners of securities.

    (2) Prescribing duties to report the creation of significant encumbrances over securities, such as pledging securities as collateral for margin accounts, using shares as collateral for borrowing without transferring the shares, and pledging shares registered with the Thailand Securities Depository Co., Ltd. (TSD).

    (3) Prescribing measures to temporarily suspend transactions where such transactions may involve taking unfair advantage or may cause serious damage to investors or the public interest.

    (4) Clarifying the revocation of seizure or attachment of assets of juristic persons, and authorizing other persons to conduct examinations on behalf of the SEC.

    (5) Amending relevant penalty provisions and provisions on settlement of fines.
