Every other major federal banking regulator got there first. The OCC proposed in February, the FDIC in April, NCUA in May, Treasury in August. On September 24, 2026, the Federal Reserve released two Notices of Proposed Rulemaking for Board-supervised payment stablecoin issuers under the GENIUS Act, and the federal supervisory picture was finally complete.
That the Fed arrived last is not surprising – the institutions it supervises (state member banks, bank holding companies, certain foreign banking organizations) operate under a different legal architecture than the OCC-chartered banks that have dominated early stablecoin activity. But the gap had a cost: Fed-supervised banks wanting to issue stablecoins had no federal rulebook. These NPRMs provide one.
Proposal 1 covers the mechanics of stability. Board-supervised issuers must fully back their stablecoins with permissible reserve assets – short-term Treasury bills and other high-quality, liquid instruments. Standardized capital requirements calibrated to credit and operational risk. Risk management standards. Rules for firms safekeeping the backing assets. Clarification that stablecoin-related activities are permissible for Board-supervised banks, which until now existed in a gray zone.
Proposal 2 defines the gate: a tailored application process for Board-supervised banks seeking to issue payment stablecoins. Business plan and financial information required, subject to a formal appeals, hearings, and determinations process. This is not a rubber stamp – it is the Fed building a structured entry point that favors institutions with the operational capacity to backstop a payment instrument.
Governor Michael Barr’s accompanying statement reads as cautious support with specific reservations. He called the NPRMs “a step in that direction” and expressed encouragement about the reserve asset limitations and standardized capital requirements. But he also flagged three areas where the final rule may look different from the proposal.
First, he wants public input on whether the rules adequately address interest rate and foreign currency risks – a real concern given that reserve portfolios heavy in short-term Treasuries face duration mismatch in a rising-rate environment. Second, he emphasized that universal redemption rights “are clear in the final rule to support public confidence in access to their funds.” Third, and perhaps most pointedly, he raised the “significant or systemic” standard from the Fed’s July anti-money laundering proposal, expressing concern that it “may have unknown effects on the Board’s ability to effectively substantiate that an institution establishes and maintains compliant programs.”
As Barr put it: “Stablecoins will only be stable if they can be reliably and promptly redeemed at par in a range of conditions. This includes during market stress, when pressure can be put on the value of even otherwise liquid government debt, and during episodes of strain on the individual issuer or its related entities.” The language is bureaucratic, but the message is not: the Fed views the current $307 billion stablecoin market – where Tether holds roughly 60% dominance and Circle roughly 24% – as a system that needs hardening before it can be treated as core payments infrastructure.
The GENIUS Act enforcement date is January 18, 2027. That is the date when it becomes unlawful for non-permitted issuers to issue payment stablecoins in the United States. The original statutory rulemaking deadline – July 18, 2026 – was missed by every agency. The Fed’s NPRMs, combined with those from the OCC, FDIC, NCUA, and Treasury, now provide the full set of proposed rules. But proposals are not final rules.
The 60-day comment period begins once the NPRMs are published in the Federal Register. That has not happened yet. Working backward from the enforcement cliff, the timeline is tight: if publication occurs in late September, comments close in late November, leaving roughly seven weeks for finalization before January 18. The agencies will need to move at a pace that rulemaking rarely achieves.
The structural pattern we have been tracking all week – infrastructure built before the rules are finished – now has a regulatory bookend. SoFi launched live stablecoin settlement on Mastercard before the Fed had even proposed its rules. Circle committed $100M in Binance equity before the GENIUS Act compliance regime existed in final form. Visa became a founding validator on Arc while the rulebook was still being written.
What changes now is that the last and arguably most important supervisor has weighed in. The Fed supervises the largest banks in the country. Its rulemaking defines what “permitted” means for the institutions that control the majority of U.S. deposit base. That the final rules may look different from the proposals – Barr’s caveats make that clear – does not diminish the structural significance of the gap closing.
As Barr concluded: “While the Board’s proposal is an important step in GENIUS Act implementation, further work will undoubtedly be required if stablecoins are to be reliable payment instruments.” For the first time, every major federal agency has laid its cards on the table. The question now is whether seven weeks is enough time to finish the hand.
