Thailand’s Securities and Exchange Commission has opened a public consultation on stablecoin rules that would cap transfers at 5 million baht, roughly $151,000, per person per licensed operator each day, and would ban deposits and withdrawals through third-party wallets entirely. The consultation, which runs until about September 25, is the sharpest move yet by a Southeast Asian regulator against the use of stablecoins to dodge banking disclosure rules. The SEC framed the proposal as a response to money laundering, cybercrime and cross-border capital flight, and the final shape of the rules will depend on the comments it receives.
What the proposal actually says
The core principle is simple: if money moves through a regulated digital asset operator, it has to stay inside the customer’s own verified accounts. Deposits must originate from a wallet or bank account verified as belonging to the same customer, and withdrawals must go to one as well. Sending stablecoins to a friend, a merchant or an unhosted wallet you control but have not verified would fall outside the permitted flow.
The 5 million baht cap applies separately to inbound and outbound transfers, so a user could in theory move about $302,000 through an operator in a single day if they both received and sent at the limit. Transfers between Thai-regulated operators that comply with the Travel Rule are exempt from the cap, a carve-out that keeps ordinary exchange-to-exchange activity alive while squeezing everything else.
The SEC has also signaled that limits could be tied to verified income, which would push the framework beyond a flat cap and toward a suitability model more common in securities brokerage than in payments. That detail alone, if it survives the consultation, would make Thailand’s rules among the strictest in the region.
Why now: the USDT problem
The timing traces back to July, when the Bank of Thailand flagged abnormal trading volumes in Tether’s USDT. The central bank’s concern was specific: stablecoins were being used to move money outside the normal banking system, where large cash transactions trigger disclosure requirements. Thai authorities had watched USDT volumes climb as the token became a settlement layer for trade and remittances in the region, much of it outside licensed channels.
Thailand is not acting alone. The country’s Travel Rule for digital assets, which will require operators to share originator and beneficiary information on transfers, takes effect on February 27, 2027. The stablecoin proposal is effectively the warm-up act for that framework, giving operators a compliance regime to build against before the reporting obligation lands.
The two measures fit together deliberately. The Travel Rule handles the question of who sent what to whom. The proposed stablecoin rules handle the question of who is allowed to move money through a licensed venue at all. Regulators who have watched crypto enforcement fail in court know that going after transactions after the fact is hard; controlling the on-ramp and off-ramp is easier, and that is exactly where Thailand is aiming.
| Measure | Detail |

| Daily cap | 5 million baht, about $151,000, per person per operator |
| Direction | Applies separately to inbound and outbound transfers |
| Third-party wallets | Prohibited for deposits and withdrawals |
| Exemption | Transfers between Travel Rule-compliant Thai operators |
| Income link | Limits may be tied to verified income |
| Consultation deadline | Around September 25, 2026 |
| Travel Rule effective | February 27, 2027 |
How Thailand compares
Other regulators in the region have taken different angles on the same problem. Singapore’s central bank proposed a stablecoin licensing framework this month that requires 100 percent reserves and bars interest payments to holders, but it did not cap transfer sizes. Thailand’s approach targets the flow of money rather than the issuer, which puts the compliance burden on exchanges and wallet providers instead of token issuers like Tether or Circle.
The contrast matters for the industry. Issuer-focused rules, like those in the US GENIUS Act, standardize what a stablecoin is. Flow-focused rules, like Thailand’s, decide who can move one and how much. A Thai exchange now faces a dual obligation: verify the wallet on both ends of every transfer and police a per-person daily ceiling, with no obvious technical standard for doing either at scale.
The verification requirement is the heavier lift of the two. Proving that a withdrawal address belongs to the customer requires either signature-based proof of control for self-hosted wallets or account-name matching for exchange-hosted ones, and both approaches have known failure modes. Exchanges in other jurisdictions that have implemented similar withdrawal-address rules, notably in the UK and under Japan’s travel rule regime, have handled it with attestation screens and spot checks rather than continuous verification. Thailand’s proposal does not yet specify which model it expects.
“The SEC said the proposal aims to reduce risks related to money laundering, cybercrime and circumvention of cross-border transfer rules.”
The enforcement gap
The obvious weakness in the proposal is self-hosted wallets. A user who holds USDT in an unhosted wallet can still send it to anyone, anywhere, and the cap only bites when the funds touch a licensed operator. Someone moving $500,000 out of the country could split the transfer across multiple operators, or across multiple days, or route it through a decentralized exchange where no licensed intermediary sits in the middle. The SEC’s own materials acknowledge the rules apply to transfers through regulated operators, not to on-chain activity between private wallets.
There is also the smurfing problem. Caps per operator invite users to open accounts at several operators, none of which sees the full picture. The Travel Rule exemption partially addresses this for operator-to-operator transfers, but only if every operator in the chain is enforcing it and sharing data. Cross-operator aggregation of daily volumes, the control that would actually catch structuring, is nowhere in the proposal.
That leaves the framework aimed at the formal sector: exchanges, brokerages and payment platforms. It will likely push more high-value activity toward informal channels, the opposite of what regulators usually want, or simply offshore it to operators beyond Thai jurisdiction. Defenders of the proposal would argue that forcing the formal market to know its customers is worth that cost, and that informal hawala-style networks existed long before stablecoins and will exist regardless of what the SEC writes.
What it means for the market
Thailand is one of Southeast Asia’s more active digital asset markets, and USDT is the dominant trading pair on local exchanges. A $151,000 daily ceiling is generous for retail users and tight for businesses. A cross-border trader settling invoices in USDT, or a remittance firm using stablecoins for payout corridors, could hit the cap in a single transaction. The exemption for Travel Rule-compliant operator-to-operator transfers is the pressure valve, but it only works if both ends are Thai-licensed or covered by equivalent regimes.
The business impact would land hardest on the border trade economy. Thai exporters and importers, particularly those trading with neighbors where banking channels are slow or expensive, have adopted USDT as a working settlement tool. Capping per-person flows at $151,000 a day, with income verification on top, forces that activity back into the banking system or into gray channels. The Bank of Thailand wants the former; the market may deliver the latter.
Operators now have about two weeks to comment. The realistic outcomes range from the cap staying as drafted, to a higher threshold for verified business accounts, to the income-linkage idea being dropped as unworkable. Either way, Thailand has put a number on the table, and numbers are harder to walk back than principles.
For the broader stablecoin industry, the proposal is a test case for whether flow controls can coexist with a payments business. Card programs, remittance products and corporate treasury tools all assume the ability to move meaningful value through a single venue. If Thailand’s final rules force those products to fragment across operators, the market will learn quickly whether stablecoin payments can survive being treated like a securities account rather than a bank account.
The consultation closes around September 25. Final rules, and any transition period for existing users, will follow. Watch for operator responses first: the exchanges that hold Thai licenses have the most to lose and the clearest incentive to argue for a business carve-out before the text hardens.
