Fed Stablecoin Rules Under the GENIUS Act: What Changes Now, and What Waits Until 2027

On September 24, 2026, the Federal Reserve Board published two proposals for regulating stablecoin issuers under the GENIUS Act, and the headlines quickly ran ahead of the documents. "Fed releases stablecoin rules" reads like the switch has been flipped. For anyone holding or using dollar stablecoins, the real question is narrower: do the Fed's new GENIUS Act proposals change anything about the stablecoins you hold today, and when do the actual rules arrive?

The short answer

Not yet, and probably not directly for most holders. These are proposed rules, not final ones. Public comments are open until November 30, 2026. The proposals are aimed at a narrow group of issuers the Fed supervises, mainly subsidiaries of insured state member banks. What matters is the template they set out: full reserve backing, capital charges, a ban on paying yield to holders, and a defined path for banks to apply. The legal regime itself starts on January 18, 2027 at the latest. That date is set by statute, not by this proposal.

What the Fed actually proposed

According to the Board's September 24 press release (issued at 2:30 p.m. EDT), the package has two parts.

Proposal one: operating standards

The first proposal would require Board-supervised issuers to "fully back their stablecoins with certain permissible reserve assets, such as short-term Treasury bills." It would also set standardized capital requirements for credit and operational risk, risk-management standards, and rules for safekeeping reserve assets, and it would clarify which stablecoin activities Fed-supervised banks may carry out. The Federal Register notice (Docket R-1899, published September 29, 2026) adds two points that matter to users:

• No yield for holders. Board-supervised issuers "must not pay the holder of any payment stablecoin any form of interest or yield (whether in cash, tokens, or other consideration) solely in connection with the holding, use, or retention of such payment stablecoin."
• No circular backing. The notice states that payment stablecoins are not themselves a permitted reserve asset.

It also implements the Act's tying prohibition, which the notice says applies to all permitted payment stablecoin issuers, not only those the Fed supervises.

Proposal two: how a bank applies

The second Federal Register notice (Docket R-1900) sets out how an insured state member bank would seek approval for a subsidiary to issue payment stablecoins. The Board would have to tell an applicant whether its file is complete within 30 days, and decide within 120 days of submission. If it misses that deadline, "the application shall be deemed approved." Uninsured state member banks can apply to state regulators instead.

Who this actually covers

This is the part most coverage skipped. In the application notice, the Fed counts 703 insured state member banks as of December 31, 2025. It estimates that only between 5 and 10 of them may seek approval for a stablecoin subsidiary. The operating-standards notice also brings in state-qualified issuers that are uninsured state-chartered depository institutions and have moved under the Board's framework.

The best-known dollar stablecoins are issued by non-bank companies, not by subsidiaries of Fed member banks. The GENIUS Act splits supervision among several regulators, and other agencies wrote their own rules. According to The Block, the OCC, FDIC, NCUA and Treasury had all published GENIUS Act proposals earlier in 2026. So the Fed's package is one piece of a larger set of rules. It is not a rulebook for the whole market.

Why the timing matters

The GENIUS Act was signed on July 18, 2025. As the Fed's application notice states, its framework takes effect on the earlier of two dates: 18 months after enactment (January 18, 2027), or 120 days after the primary federal regulators issue final implementing rules. Congress also gave regulators one year to write those rules. The Block reported on July 18, 2026 that the deadline passed without final rules.

The Fed is publishing proposals in late September with comments due November 30. That leaves little room before January 18, 2027. The OCC is moving faster. Comptroller Jonathan Gould said on August 19 that "we will have a final rule out by November," according to PYMNTS, and Decrypt quoted him saying the agency wants to begin processing applications "within the new year."

Even the Fed says this isn't finished

Governor Michael Barr's statement on the release, as reported by PYMNTS, was candid: "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." He asked for public input on the limits on reserve assets, on the capital requirements, and on whether the rule adequately handles interest-rate and foreign-currency risk. Those are the risks that could test a stablecoin's ability to redeem at par during a market shock.

The useful reading for holders: the direction is clear (fully reserved, non-yielding, capital-backed tokens), but key details such as how strict the reserve and capital tests will be are still open for comment.

What we know vs. what we're inferring

Known (from primary documents):

• The Fed issued two proposals on September 24, 2026. Both were published in the Federal Register on September 29, with comments due November 30, 2026.
• The proposals require full reserve backing with permissible assets such as short-term Treasury bills, set standardized capital requirements, and bar Board-supervised issuers from paying holders interest or yield.
• The application process has 30-day completeness and 120-day decision deadlines, with deemed approval if the Board misses them.
• The Fed estimates 5 to 10 insured state member banks may apply.
• The GENIUS Act takes effect by January 18, 2027 at the latest.

Inferred or uncertain:

• That the final Fed rule will closely track the proposal. Comments can and often do change rules, and Barr explicitly flagged open questions.
• Whether all regulators' final rules will be in place before January 18, 2027. The OCC has stated a November target; we have not seen a stated finalization date for the Fed's rules.
• Precise reserve-asset lists, redemption timelines and capital calibrations. Some secondary reports describe specific figures that we could not confirm in the portions of the Federal Register text we reviewed, so we have left them out.

What to watch next

• November 2026: the OCC's stated target for its final GENIUS Act rule.
• November 30, 2026: comment deadline for both Fed proposals (Dockets R-1899 and R-1900). Public comment letters, especially from banks and stablecoin issuers, will show where the fight over reserves and capital is.
• January 18, 2027: the latest date on which the GENIUS Act framework takes effect under the statute.
• After the comment period: a final Fed rule. Compare it with the proposal on reserve limits, capital and the yield ban.
