Thailand Proposes 5 Million Baht Stablecoin Transfer Cap

Thailand wants a daily speed limit on stablecoins. Its Securities and Exchange Commission board has approved principles capping transfers at 5 million baht per day, roughly $151,000, and banning licensed operators from touching third-party wallets. The decision, published as SEC announcement No. 183/2026 dated Sept. 3, is out for public comment until Sept. 25, Crypto Briefing reported.

The hinge is a same-customer rule. Money entering a customer's account at a licensed operator must come from a wallet verified as that customer's own. Money leaving must go to one. Transfers in from another person's wallet, or out to one, would be prohibited outright.

Verification goes beyond checking a name. Wallets must satisfy Travel Rule requirements, customer profiling, and screening against mule accounts and crime-linked parties, plus blockchain analytics tracing movements to high-risk or watchlist wallets. Transfer values must fit the customer's declared income and financial position. Falling beneath 5 million baht does not make a transfer acceptable by itself. Operators must still weigh the customer's profile, source of funds, transaction history, counterparties, and stated purpose. A declaration alone will not pass: operators need documented procedures proving control of each self-hosted wallet, with evidence standards, exception handling, and audit trails that separate personal wallets from custodial accounts, business addresses, smart contracts, and shared-control addresses.

A declaration alone will not pass. Operators need documented procedures proving control of each self-hosted wallet, with evidence standards, exception handling, and audit trails that separate personal wallets from custodial accounts, business addresses, smart contracts, and shared-control addresses. The SEC page carrying the announcement also links a parallel public-comments document and an earlier issuance on the digital-asset Travel Rule.

The 5 million baht ceiling applies separately to inbound and outbound flows, per person, per operator, per day. One carve-out exists. Transfers between customer accounts at two supervised Thai operators escape the cap when both apply Travel Rule requirements. The package also pulls market makers, liquidity providers, and off-platform trades under explicit supervision.

"The SEC is committed to supervising the capital market and the digital asset market in a manner that keeps pace with relevant developments and risks," said Mrs. Pornanong Budsaratragoon, the SEC's secretary-general. Hearing results will feed into further rule revisions, she said.

The trigger was volume the regulator could see climbing through licensed operators, particularly USDT, alongside patterns pointing to money laundering, cybercrime, and evasion of international transfer rules. The principles were developed with the Bank of Thailand, the Thai Digital Asset Operators Trade Association, and licensed operators. The Bank of Thailand flagged abnormal USDT trading volumes in July 2026, concerned stablecoins were sidestepping banking disclosure requirements, Crypto Briefing reported.

Behind the platforms, the rules bite too. Exchanges would name market makers and disclose which assets each supports, then screen and review them continuously. Liquidity providers and source exchanges behind brokers would need supervision by a competent authority. Off-platform broker services face a 3 million baht minimum with published buy and sell prices, and brokers could not match two customers directly off-platform, routing them to a licensed exchange instead, according to FinCrime Central's analysis. Exemptions cover operators moving assets in their own name, Bank of Thailand-supervised entities under specific authorization, and qualifying token-baht market makers. Providers cannot sit in jurisdictions lacking Financial Action Task Force measures.

For users, the practical effects are blunt. Exchange accounts stop working as peer-to-peer rails. Treasury setups shifting funds between different entities' wallets lose their path through licensed operators outside the exemptions. Every wallet touching a regulated system must belong to the account holder, and transfer sizes must match the customer's finances, not just their identity.

Liquidity providers and source exchanges behind brokers would need supervision by a competent authority. Providers cannot sit in jurisdictions lacking Financial Action Task Force measures. Brokers would disclose each provider's identity and conflicts, and establish the source of assets and the true purpose behind transactions. Exemption claims would need confirmed legal identity, regulatory status, business purpose, and authorization, not a customer's label.

Enforcement gets new tools. Operators that fail to collect or disclose required information face correction orders with deadlines, then directions to act or stop acting until complete data exists. Monitoring must look past single transactions to cumulative flows, customer relationships, shared wallet exposure, rapid post-receipt movement, repeated just-below-threshold transfers, and foreign platform links.

Gaps remain by design. Purely peer-to-peer transfers that never touch a licensed Thai operator sit outside the proposal. Users could split activity across operators, connected persons, or multiple self-hosted addresses. The SEC's answer is aggregation and behavioral checks plus a Travel Rule developed with the Anti-Money Laundering Office that takes effect Feb. 27, 2027 with five-year record retention. The principles stay a proposal until the hearing concludes on Sept. 25.
