The Thailand Securities and Exchange Commission (SEC) has amended the listing rules for digital asset exchanges, aiming to align requirements with current digital asset industry practices and use cases while maintaining investor protection and supervisory controls against conflicts of interest, market manipulation, and unfair trading. The amended rules take effect on 1 December 2025. The changes allow a digital asset exchange to list cryptocurrency or ready-to-use digital tokens issued by the exchange itself or an affiliated person for use on blockchain. Exchanges must also disclose, through the SEC’s electronic reporting (e-reporting) system, the list of an issuer’s related persons for any digital tokens that issuer lists on the exchange, to support monitoring and investigation of insider trading and to strengthen insider-trading prevention using off-site smart detection tools. For digital tokens already listed before the new rules take effect, exchanges must ensure the relevant issuers provide their related-person information to the exchange within 90 days from the effective date. The SEC noted that public comments collected during June to July 2025 broadly supported the principles, and it has issued the relevant notifications to implement the changes.
