The U.S. Treasury will stop accepting public comments on October 19 for its proposed rule implementing Section 3 of the GENIUS Act, the first federal framework that defines which institutions may issue payment stablecoins pegged to the dollar.
What the rule would do
Congress passed the GENIUS Act in July 2025, setting a statutory clock for regulators to stand up a licensing and supervision regime for payment stablecoins. Treasury’s August 18, 2026 Federal Register notice translates that mandate into operational requirements: permitted issuers, reserve asset standards, redemption rights, and restrictions on who may offer tokens to U.S. consumers.
The proposal matters to anyone holding USDC, USDT, or bank-issued tokenized deposits on mobile apps. Today those products operate under a patchwork of state money-transmitter licenses and enforcement actions. A final Treasury rule would tell banks, credit unions, and certain nonbank firms which path they must use to keep serving retail users lawfully.
Why the date moved to a Monday
Treasury opened a 60-day comment window when it published the notice. The 60th calendar day fell on a Saturday, so the deadline rolls to the next business day, October 19, according to regulatory trackers who monitor docket TREAS-DO-2026-0496. Some crypto news aggregators displayed a November date tied to an older 2025 advance notice; Treasury’s current docket shows no extension as of October 10.
Commenters may file through the federal rulemaking portal or by mail to Treasury’s Office of General Counsel. Trade groups representing banks, payment apps, and blockchain firms have already submitted letters debating whether only insured depositories should issue tokens or whether qualified nonbanks can participate with tighter reserve rules.
Stakes for consumers and fintech
Payment stablecoins fund a growing share of remittances, freelance payroll, and exchange trading pairs. If the rule narrows eligible issuers, apps that rely on third-party tokens may need new partnerships or state licenses. If the rule is permissive, expect more bank-branded dollar tokens inside existing checking apps.
Wallet users should not confuse the comment deadline with a ban date. This step is notice-and-comment rulemaking; a final rule typically follows months later, often with a phased compliance date. Still, firms are budgeting legal costs now because the GENIUS Act includes statutory milestones for when unapproved issuance must stop.
How to participate
Individuals can submit short comments describing consumer experiences: redemption delays, fee disclosures, or fraud losses. Reference the docket number and attach no sensitive account data. Small-business owners who pay overseas contractors in stablecoins may explain operational reliance on 24/7 settlement.
Members of Congress have largely deferred to Treasury on technical reserve standards, so administrative comments carry unusual weight in this cycle. After October 19, the agency will read the record and publish a final rule or a revised proposal.
Calendar context
The same week brings unrelated federal deadlines—campaign finance reports, health enrollment marketing rules, and commodity regulators’ own crypto-market notices—but Treasury’s stablecoin docket is the policy file most likely to reshape how dollars move on chain for retail users. Missing the comment window does not block you from complying later, but it closes the formal chance to shape reserve and redemption language before litigation begins.
Mark October 19 on your calendar if you hold stablecoins outside a regulated bank account or run a business that pays vendors in tokenized dollars. The rule will not pass in a day, yet the record Treasury closes that Monday will echo through compliance departments for years.
