The OCC finalizes its GENIUS Act stablecoin rule, effective 18 January 2027

The Office of the Comptroller of the Currency published its final rule implementing the GENIUS Act in the Federal Register on 23 October 2026. It is the OCC's version of the stablecoin rulebook for the banks it charters and supervises. The proposal appeared in the Federal Register on 2 March 2026.

The rule's dates line is one sentence long: "The final rule is effective on January 18, 2027." The OCC's news release adds that "The final rule and the GENIUS Act take effect on January 18, 2027." So the statute and the OCC's rules switch on together.

Who it reaches

The OCC's bulletin carries a "Note for Community Banks", and it starts plainly: "The final rule will apply to national banks and their subsidiaries." The rule's own scope section lists "national banks and their subsidiaries, Federal savings associations and their subsidiaries, Federal branches and their subsidiaries," as well as foreign payment stablecoin issuers and nonbank companies that want to become, or already are, Federal qualified payment stablecoin issuers.

For a bank, the route in is a subsidiary. The application and registration provisions apply to insured national banks, federal savings associations and federal branches "that seek to issue payment stablecoins through a subsidiary."

This rule is about the institutions the OCC supervises. We covered the Federal Reserve's own proposals in an earlier post.

What the rule does

It adds a new part 15 to title 12 of the Code of Federal Regulations and amends parts 3 (capital adequacy), 6 (prompt corrective action), 8 (assessment of fees) and 19 (rules of practice and procedure). The bulletin says part 15 covers activities, reserve assets, redemption, risk management, audits and reports, supervision, custody, applications and registrations, revocation of approval, and capital and operational backstops, among other things.

The core of it is reserves. A payment stablecoin has to be "backed on at least a 1 to 1 basis by reserve assets." The OCC says the final rule "makes several changes to the provisions concerning reserve asset management" and that "The capital elements have also been simplified relative to the proposal." The preamble also notes that, under the Act, "deposit liabilities of institutions that are not insured depository institutions do not qualify as reserve assets."

Three definitions are worth a look if you have investors or a holding company. Control turns on whether a person "has power to vote 25 percent or more of any class of voting securities." A principal shareholder is someone who "will own, control, or hold 10 percent or more of the voting stock." And the rule carries through "the statutory prohibition against paying interest or yield solely in connection with the holding" of a stablecoin.

The OCC says it "received approximately 328 comments" on the proposal, which its release describes as coming "from a wide variety of stakeholders."

What it leaves out

The rule doesn't cover the Bank Secrecy Act, anti-money laundering or OFAC sanctions requirements. The bulletin says these "will be addressed in a separate rulemaking in coordination with the Department of the Treasury." The door isn't open yet, either. The OCC will announce separately "when it will begin accepting and processing applications and waiver requests."

Tokenized deposits stay outside the rule. The preamble says the payment stablecoin definition "excludes deposits, including deposits in tokenized form." If your bank is looking at putting deposits on a distributed ledger, this rule is not the one that governs that product.

What it could mean

We think most community banks will never file an application under part 15. Running a stablecoin subsidiary means holding reserves at least one for one, honouring redemption, and carrying a capital and operational backstop, all for a product the issuer can't pay interest on just for being held. That's a lot of cost for a small institution, with no obvious way to earn it back.

The rule still matters if you're not issuing. Fintech partners and core vendors are going to pitch stablecoin and tokenized deposit products, and the line between the two is now written down in a final rule. If a vendor calls something a tokenized deposit, our guess is that examiners will ask whether it really is a deposit. Ask the same question before you sign.

The missing BSA and sanctions rules are the part we'd watch. Any bank that does move ahead will be building its program before it knows what the Treasury-coordinated rule asks for. That's an uncomfortable spot, and a sensible reason to wait.

Then there's timing. Nothing changes until 18 January 2027, and nobody can apply until the OCC says so. For most of you, that's time to read part 15 once, note where it touches your vendor contracts, and move on.
