Foreign stablecoins face a 2028 US deadline — the token keeps working, the buy button may not

The US Treasury has proposed rules under the GENIUS Act that would, from July 18, 2028, stop regulated crypto businesses from offering or selling a payment stablecoin to someone in the United States unless the issuer fits one of the law's permitted categories. The token itself would keep circulating and moving between private wallets exactly as it does now. What changes is whether an American exchange can keep the buy button on.

The proposal arrives in stages. Treasury expects the broader regime to take effect on Jan. 18, 2027, when companies would no longer be able to issue a payment stablecoin in the United States without entering the GENIUS framework, and when a US provider carrying a foreign-issued token would face initial conditions tied to the issuer's ability and commitment to obey lawful orders. The wider distribution restriction follows on July 18, 2028. The Federal Register comment period runs until Oct. 19, so the details can still change before a final rule.

The businesses caught by the rule are the ones beginners actually use. Digital asset service provider sounds like a narrow legal category, but it covers exchanges, custodians, and companies that transfer digital assets. Treasury also reads offer or sell broadly: advertising a stablecoin can count, so can agreeing to sell it, or telling a customer who reached out first that the trade can be completed. Helping someone get around geolocation controls counts as well.

Self-custody sits largely outside the framework. The proposal excludes people sending stablecoins on their own behalf, direct peer-to-peer transfers, and software that simply helps someone hold their own assets. An American could still hold or receive an offshore token; the friction begins when they try to buy, swap, or deposit it through a covered business. The location test is mainly physical, too. A US resident temporarily abroad would generally be treated as outside the country for a transaction conducted there, and a non-US resident visiting the United States gets a narrow exception in specified circumstances.

Tether's USDT is the clearest live example. It is issued outside the United States but is currently available to US customers through venues including Coinbase and Kraken, subject to each platform's own eligibility rules. Foreign issuers do have a route in, under Section 18 of GENIUS: the home country must run a stablecoin regime Treasury considers comparable to the American one, the issuer must register with the Office of the Comptroller of the Currency, and it must show it can comply with lawful US orders. Treasury is also asking whether an exchange's due diligence should include examining a foreign issuer's smart contracts to confirm it can seize, freeze, or burn tokens when legally required. Tether holds digital asset and stablecoin issuer licenses in El Salvador, has frozen addresses while working with US authorities, and launched a separate federally regulated dollar token, USA-T, in January.

None of this requires action today, and none of it is investment advice. What is worth internalising is the shape of the change: the same dollar token can be freely transferable on-chain and still unavailable on the platform where you keep your account. If you hold a stablecoin, it is reasonable to know which entity issues it and where that entity is regulated. And if a listing does eventually change, the announcement will come from your exchange's own official channels, never from a message asking you to connect your wallet somewhere to migrate anything.
