The GENIUS Act stablecoin rules deadline passed on Saturday 18 July 2026 with ten proposed rulebooks on the table and none of them finalised. Section 13 of the Act, signed on 18 July 2025, gave the OCC, the Federal Reserve, the FDIC, the NCUA and Treasury exactly one year to complete implementing regulations. They did not. Our reading for anyone weighing a US stablecoin issuer licence: treat every proposed requirement as unsettled, and plan against the one date that did not move, 18 January 2027.
A missed rulemaking deadline usually reads as breathing room. Here it works the other way, because the statute's effective date is fixed and the delay comes out of issuers' build time, not the government's.
When does the GENIUS Act take effect?
Section 20 sets the effective date at the earlier of 18 months after enactment, which is 18 January 2027, or 120 days after final rules land. The OCC confirmed that mechanic in Bulletin 2026-3. Any rule finalised after roughly 20 September 2026 leaves the January date controlling, so every further week of agency delay subtracts a week from implementation runway. The procedural arithmetic was already impossible before the deadline arrived: comments on the NCUA's second package only closed on 17 July 2026, one day before the statute required final text.
GENIUS Act stablecoin rules deadline: what is still unsettled
The proposals cover the full licensing stack: reserves, capital, liquidity, custody, redemption and reporting from the OCC (published 2 March 2026), prudential standards and deposit-insurance treatment from the FDIC (10 April 2026), and licensing plus operational risk from the NCUA (February and 18 May 2026). The comment files show live fights over substance, with BlackRock pressing the OCC to scrap a proposed 20 per cent cap on tokenised reserve assets and to confirm Treasury ETFs qualify as reserves.
Treasury's 3 April 2026 proposal on which state regimes count as "substantially similar", the gate that lets issuers with under $10 billion outstanding stay under state supervision, is also unfinished. Teams assuming the state route will be cheaper or faster are planning against a target that has not been fixed. That federal-or-state fork will feel familiar to anyone who watched national European regimes give way to MiCA, and it is the kind of moving-target decision our crypto licence comparison is built for.
Two comment windows close in August
The near-term action items sit well before January. The FDIC's Bank Secrecy Act and sanctions compliance proposal for FDIC-supervised issuers takes comments until 4 August 2026, and the joint customer identification programme proposal from FinCEN, the OCC, the Federal Reserve, the FDIC and the NCUA runs until 21 August 2026. Both dates are on the Federal Register. If wording in either proposal would break your operating model, the window to say so closes within weeks.
Where this leaves a licensing decision
The sequencing question for founders and compliance leads is whether to spend against proposals now and absorb revision risk, or wait for final text and accept a compressed build window before 18 January 2027. Neither option is comfortable, which is precisely why the miss matters. We track the US regime on the United States crypto licensing page, and the wider stablecoin picture, including the EU's e-money route for EMT issuers, in our State of Crypto Licensing reports and the e-money licence comparison.
