OCC Finalizes GENIUS Act Stablecoin Rule: What Issuers and Users Get

Short answer: On October 21, 2026, the Office of the Comptroller of the Currency (OCC) published its final rule implementing the GENIUS Act, the US federal stablecoin law. It is the first final rule from any federal banking agency under the Act. The rule, codified as a new 12 CFR Part 15, takes effect on January 18, 2027, the same day the Act's main requirements kick in. It covers stablecoin issuers under OCC supervision, eases several points of the spring proposal, keeps the ban on paying yield to holders and requires issuers to alert the OCC if redemption requests spike.

Who does the OCC rule apply to?

The GENIUS Act splits supervision of payment stablecoin issuers between federal and state regulators. The OCC's part covers, among others, uninsured national banks and subsidiaries of insured national banks, subsidiaries of federal savings associations, "federal qualified" non-bank issuers, foreign payment stablecoin issuers that register with the OCC and some state-qualified issuers. Law firms including Skadden and Sidley describe it as the template other agencies are likely to follow; the Federal Reserve's own GENIUS proposal, which we covered in Fed GENIUS Act stablecoin rules, is still open.

Timing matters for anyone already operating. Issuers whose substantially complete application is pending on or before January 18, 2027 can request waivers of up to 12 months. After that, issuing a payment stablecoin in the US without authorization can carry criminal penalties.

Key facts

What changed from the proposal?

The most watched point was yield. The GENIUS Act forbids issuers from paying interest to stablecoin holders. The proposal went further and presumed that rewards paid by an issuer's affiliates or partners, such as exchanges, were prohibited yield unless proven otherwise. The final rule drops that presumption but keeps the OCC's power to act against arrangements designed to evade the ban, and it does not grandfather existing reward programs. In practice, exchange "earn" programs on stablecoins are not automatically illegal, but they are not safe either.

On reserves, commentators such as CertiK and Notabene summarize the final text as keeping strict liquidity and concentration limits, including an on-demand cash minimum and a cap on exposure to a single counterparty. The redemption trigger is new in spirit: if requests for more than 10% of a stablecoin's outstanding value arrive within 24 hours, the issuer must notify the OCC, giving the regulator an early warning of a run.

What does it mean for people who hold or swap stablecoins?

1. US-regulated stablecoins get a clearer status. From January 2027, coins from OCC-supervised issuers will have defined reserve, redemption and disclosure rules. That is the US counterpart to MiCA; see our overview of stablecoin rules in 2026.
2. Do not expect interest from the issuer. Yield on stablecoins, where it exists, will come from platforms and carry platform risk.
3. Foreign coins face a choice. Issuers outside the US must register or lose access to US platforms, which may change where some coins are listed. In the EU, a similar squeeze is under way for non-MiCA coins; see the ESMA deadline for USDT.
4. Keep a route between networks and issuers. If a coin or network becomes harder to use on one platform, a non-custodial swap from USDT to USDC or between TRC-20 and ERC-20 is a quick fix; compare offers in Changerella App or the exchangers list.
