The Thailand Securities and Exchange Commission has launched a consultation on three draft notifications that would revise the prohibited characteristics of major shareholders of securities, derivatives and digital asset business operators. The proposals would align the rules across these sectors, set a common standard for assessing disqualifying conduct, and broaden the misconduct that can be considered when judging whether major shareholders are fit to hold those stakes. The draft notifications would harmonize prohibited characteristics across all covered business operators to improve clarity and reflect current risk developments. The scope would be expanded to include money laundering offenses, as well as offenses related to the financing of terrorism and the proliferation of weapons of mass destruction, whether committed in Thailand or overseas. Serious offenses under all laws supervised by the SEC would also be taken into account, with the aim of addressing cross-sector risks linked to interconnected business activities. The package follows an earlier consultation on the underlying principles conducted from April to May 2026, which the SEC said received broad stakeholder support. If adopted, the notifications would include a 90-day transitional period from their effective date to give business operators and major shareholders time to prepare. The public consultation runs until 16 August 2026.
