Treasury's GENIUS Proposal Forces US Exchanges Into Audit-or-Delist Choice on Foreign Stablecoins

Published October 18, 2026, 08:20 PKT. Based on the Federal Register notice of proposed rulemaking, "GENIUS Act Regulations on Payment Stablecoin Issuance, Offer, and Sale" (docket TREAS-DO-2026-0496, published August 18, 2026) (primary source), CryptoSlate's October 18, 2026 analysis (secondary source), FinanceFeeds (secondary source), basisdesk.news (secondary source), and Yeremy's October 7, 2026 analysis via Medium (secondary source).

The US Treasury's proposed stablecoin rules would give American exchanges a binary choice on foreign-issued dollar tokens: do enough homework on the issuer to defend keeping them listed, or stop offering them. The notice of proposed rulemaking, published in the Federal Register on August 18, 2026 under docket TREAS-DO-2026-0496, implements the GENIUS Act, the federal payment stablecoin law enacted on July 18, 2025. Its comment window closes on October 19, 2026, meaning the industry has until Monday to get objections and asks on the record. The proposal does not name which tokens qualify and pointedly declines to decide whether Tether's USDT, the $184 billion stablecoin that is the third-largest cryptocurrency of any kind, can remain available on US platforms, according to CryptoSlate's October 18 analysis and FinanceFeeds.

The audit-or-delist standard

The core of the proposal shifts the access decision from the issuer to the platform. A US exchange or other digital asset service provider could keep offering a foreign-issued payment stablecoin only if it can defend why it trusted the issuer's representation that it has the technology and the intent to comply with lawful US orders, such as valid orders to freeze or seize tokens, after conducting reasonable due diligence, CryptoSlate reported. Reliance on that representation would be barred when the platform knows, has reason to know, or should know that it is false or the issuer cannot or will not comply. Treasury says the diligence should, at a minimum, confirm the issuer is not subject to a public GENIUS Act prohibition on secondary trading, though that check alone would not be enough, and platforms would need to weigh all reasonably available information about the issuer. What counts as adequate diligence is still open: Treasury is asking whether the final rule should require written or regularly updated issuer representations, record retention, smart-contract review, or checks of seize, freeze and burn functions. Those are questions, not mandates, CryptoSlate noted.

The 2027 and 2028 clocks

The proposal sets two timing points. Treasury expects the Act's general regime to take effect on January 18, 2027, the statutory deadline, unless final implementing rules trigger an earlier date, and a stricter offering limit would begin on July 18, 2028, CryptoSlate reported. From that later date, a covered provider generally could offer or sell a payment stablecoin to someone in the United States only if it came from a permitted US issuer or a foreign issuer meeting the law's Section 18 requirements. Treasury Secretary Scott Bessent framed the exercise as a request rather than a decree when the department announced the proposal on August 17, saying it "welcomes input from stakeholders as we work to provide the regulatory certainty businesses need to innovate and grow in America," according to FinanceFeeds. The OCC's parallel GENIUS rules are targeted for finalization in November 2026, per a RiskTemplate timeline, and the FDIC advanced its own stablecoin prudential proposal this month with a separate 60-day comment window, basisdesk.news reported.

The three-part foreign-issuer route

For offshore tokens, staying available on US platforms runs through three gates, not one. A qualifying foreign issuer would need Treasury to find its home regulatory regime comparable to the US framework, often described as reciprocity, register with the Office of the Comptroller of the Currency, and hold enough liquid reserves at a US financial institution to meet American redemption demand, unless a reciprocal arrangement provides otherwise, CryptoSlate and Yeremy's Medium analysis reported. Its jurisdiction also could not be under comprehensive US sanctions or designated a primary money laundering concern. Even a foreign issuer with a potential Section 18 route would not receive an automatic pass from the exchange carrying its token, CryptoSlate added, since the platform-level diligence standard sits on top of the issuer-level tests.

What the rule does not touch

The proposal is not a blanket ban on holding or directly transferring foreign stablecoins. Its exemptions include lawful direct transfers between individuals without an intermediary, certain same-parent transfers between an individual's US and foreign accounts, and transactions through software or hardware wallets used for the individual's own custody, CryptoSlate reported. And the Treasury proposal names no names: the notice does not identify qualifying tokens or decide whether USDT, at about $184 billion per FinanceFeeds, or any other named stablecoin can remain available. Until Treasury finalizes the standard and regulators make issuer-specific decisions, US availability will depend on categories and compliance evidence rather than a published list of approved foreign stablecoins.
