The 18 January 2027 effective date did not move when the deadline slipped, and any rule finalised after 20 September will lose the ability to shorten issuers' compliance runway.
Not one of the five federal agencies charged with implementing the GENIUS Act published a final rule by Saturday's statutory deadline. The Office of the Comptroller of the Currency, the FDIC, the NCUA, the Treasury Department and the Federal Reserve all reached the one-year mark with proposals still on the table, some of them still open for public comment.
President Trump signed the Guiding and Establishing National Innovation for US Stablecoins Act into law on 18 July 2025. Section 13 of the statute directed each primary federal payment stablecoin regulator, together with Treasury and each state stablecoin regulator, to promulgate implementing regulations no later than one year after enactment. The statute contains no fallback if that date slips, no automatic extension, and no interim guidance framework. Lawmakers had been warned. Six agencies were on the clock heading into July and none of them cleared it.
What the agencies delivered instead is a stack of proposals at varying stages of unfinished. The OCC published its broad implementing rule for federally chartered issuers on 2 March, covering reserve assets, capital, liquidity, custody, risk management and reporting. The FDIC followed in April with a prudential-standards proposal for issuers owned by FDIC-supervised institutions. The NCUA issued a licensing proposal in February and a much broader operational and risk-management proposal in May whose comment window closed on Friday, one day before the deadline. That mechanically ruled out a Saturday final rule under the normal notice-and-comment process.
Treasury's proposed principles for judging when a state framework is "substantially similar" to the federal regime, which would let qualifying issuers with up to $10 billion in outstanding stablecoins remain under state supervision, also remain unfinished. So does a joint customer-identification proposal from the Federal Reserve, FinCEN, OCC, FDIC and NCUA whose comment window runs through 21 August. A separate FDIC proposal covering Bank Secrecy Act and sanctions compliance is open for comments through 4 August. FinCEN and OFAC's AML and sanctions proposals are also still in the pipeline.
The scale of the industry backlog was already visible in the comment record. BlackRock used the OCC's window to warn the agency that a 20 per cent cap on tokenised reserve assets would cripple its BUIDL fund and asked for explicit confirmation that qualifying Treasury ETFs could be used as reserves. That single letter runs 17 pages. Multiply it across every issuer, custodian and bank trade group with a filing on record, and reconciling that much feedback in five weeks was never a realistic timetable for the agencies.
Bryan Steil, the Wisconsin Republican who chairs the House Financial Services Digital Assets Subcommittee, pressed regulators in December to finish on time, noting that federal agencies had a history of missing congressionally mandated dates. A bipartisan group of senators wrote to Treasury in June asking the department to preserve states' regulatory role and complaining that Treasury's proposal left the certification process, and its timing, unclear. Neither concern was addressed by Saturday.
The consequence of the missed deadline is not that the framework goes away. Section 20 says the law takes effect on the earlier of 18 January 2027 or 120 days after the primary federal regulators issue final implementing rules. That first date does not move because the second one slipped. It does, however, close a door: any rule finalised after 20 September will run out its 120-day window on or after 18 January 2027, so no future final rule can pull the effective date forward. The agencies have lost whatever room they had to shorten the runway for issuers.
What issuers are left preparing against is a set of moving proposals whose final shape they will not know for months. The GENIUS Act itself is prescriptive on the fundamentals: one-to-one reserves in eligible liquid assets, published redemption policies, monthly reserve disclosures and no interest paid directly to holders. The Treasury has already told stablecoin issuers they will be treated as banks for AML purposes. The pending rules will settle capital floors, liquidity buckets, custody standards, application procedures, AML programmes and the state-supervision threshold. None of those are trivial for a business that has to be authorised and operating before 18 January 2027.
New York's Department of Financial Services has already proposed its own GENIUS-aligned framework, adding reserve-concentration limits and other requirements in an effort to meet whatever the federal "substantially similar" test turns out to be. Because the federal test is still a proposal, New York and every other state that has moved first may have to revise once Treasury commits.
The missed deadline sits inside a broader pattern. When the Dodd-Frank Act imposed comparable rulemaking dates on the SEC and CFTC in 2010, those agencies missed roughly 40 per cent of them. Congress rarely writes penalties into those deadlines and it did not here. What GENIUS did do, uniquely, was mandate an effective date that runs on the calendar rather than on the agencies' output. That is why Saturday tightened the runway rather than moving the goalposts.
