SEC seeks public comments on proposed amendments to regulations concerning “prohibited characteristics of major shareholders” of business operators



Friday 17 July 2026 | No. 153 / 2026


Bangkok, 17 July 2026 – The Securities and Exchange Commission (SEC) is seeking public comments on draft notifications proposing amendments to the prohibited characteristics of major shareholders of securities business operators, derivatives business operators, and digital asset business operators (collectively, the “business operators”), with the objective of ensuring that major shareholders possess appropriate qualifications and enhancing the credibility of the Thai capital market.

Earlier, the SEC revised the principles on the prohibited characteristics of business operators to provide greater clarity and to better reflect current risk developments. The SEC then conducted a public hearing on the proposed principles from April to May 2026, with most stakeholders expressing agreement with the proposed principles.

The SEC has therefore prepared three relevant draft notifications in line with the proposed principles and is now seeking public comments. The key provisions are as follows:

        (1) The prohibited characteristics of major shareholders would be harmonized across all types of business operators to provide greater clarity and to better reflect evolving risk developments. For example, the scope of consideration would be expanded to cover money laundering offenses, as well as offenses relating to the financing of terrorism and the proliferation of weapons of mass destruction, both in Thailand and overseas. In addition, serious offenses under all laws under the SEC’s supervision would be taken into account to comprehensively address cross-sector risks arising from interconnected business activities.

        (2) A unified standard for prohibited characteristics and for the assessment of the severity of conduct of major shareholders across all types of business operators would be established.

        (3) A 90-day transitional provision would apply from the effective date of the notifications to allow business operators and major shareholders sufficient time to prepare prior to the notifications taking effect.

The consultation paper is available on the SEC website at https://www.sec.or.th/TH/Pages/PB_Detail.aspx?SECID=1189 and on the Legal Hub at https://law.go.th/. Stakeholders and interested parties are invited to submit comments through these websites or by email to aurawan@sec.or.th, gritchanut@sec.or.th, and witchulada@sec.or.th (for securities and derivatives business operators) or jirapat@sec.or.th and wasu@sec.or.th (for digital asset business operators). The public hearing ends on 16 August 2026.
