OCC finalised stablecoin rules that take effect in January

The OCC issued its final rules on 21 October, putting the GENIUS Act into practice for payment stablecoin issuance and custody. They take effect on 18 January 2027, which is 88 days away. Reserves must at least equal the coins outstanding, and a redemption request must generally be met within two business days.

What the interest ban is worth

The clause with the most money behind it is the one that bans paying interest or yield for simply holding a stablecoin. That survives, although the OCC dropped a presumption against certain affiliate arrangements, which is where the argument will move next.

So we priced the ban. The US Treasury put the three-month bill at 4.26% on 20 October. Against the $305.59bn of stablecoins we counted across the whole category yesterday, reserves of that size earn roughly $13bn a year. The rule decides who keeps it, and the answer is not the holder.

The redemption window, measured

The two-day window deserves the same treatment. One percent of today's float asking for dollars at once is $3.06bn to be paid inside two business days. For comparison, USD1 lost $409m over a fortnight this month without the peg moving, which is a slow event by this standard. The window is written for the fast one.

The scope is wider than banks. The rules cover national banks, federal savings associations, federal branches and their subsidiaries; nonbank firms seeking federal qualified issuer status; and state-qualified issuers where the OCC has authority. That third category is the one that decides whether a state licence becomes a federal relationship. It also settles a question issuers have been asking for a year: whether a stablecoin licensed in one state can be distributed everywhere without a second approval, and the answer now runs through Washington rather than around it.

What is missing

Two pieces are missing on purpose. The Bank Secrecy Act, anti-money-laundering and sanctions requirements come in separate rulemaking, and the OCC has not said when it starts processing issuer applications and waiver requests. A finished rulebook with no open window is a date rather than a licence.

“We are providing a clear, practical framework for payment stablecoin innovation, with strong standards for reserve backing, redemption, and risk management.”

— Jonathan Gould, Comptroller of the Currency

Comptroller Jonathan Gould calls it a clear, practical framework with strong standards for reserve backing and redemption. What settles whether it is also a working one is the application window, the AML text, and whether the affiliate carve-out turns the interest ban into a formality that issuers route around.
