OCC GENIUS Act final rule: the stablecoin rulebook is written for issuers, and a merchant's checklist is short
Key takeaways
- The rule binds issuers: banks, federal branches, nonbank qualified issuers and foreign issuers under OCC jurisdiction. Nothing in the OCC's description puts a duty on the business that gets paid.
- Yield stays gray: the OCC dropped the proposed presumption against third-party rewards and will judge arrangements case by case. A rewards offer to a merchant is still a bet on a future ruling.
- Two numbers on reserves: the American Action Forum reports 5% in demand-available funds and a 40% cap on any single counterparty. On a $2 billion issuer that is $100 million and $800 million.
- Anti-money-laundering rules are missing: Bank Secrecy Act and sanctions rules go to a separate rulemaking with Treasury, so issuer freezes stay a risk you size yourself.
On October 21, 2026, the Office of the Comptroller of the Currency published its final rule implementing the GENIUS Act, the 2025 US law for payment stablecoins. The OCC's release, NR 2026-92, says the rule covers permitted payment stablecoin issuers, foreign issuers under OCC jurisdiction and custody by OCC-supervised entities.
What the OCC published, and when it bites
The Act was signed on July 18, 2025. The OCC proposed its rule on February 25, 2026 and the proposal reached the Federal Register on March 2. According to The Paypers, most of the final text sits in a new part of the regulations, 12 CFR Part 15. It covers issuer activities, reserve assets, redemption, risk management, audits and reports, custody, applications, revocation and a capital and operational backstop.
The rule takes effect on January 18, 2027, the same day as the Act. As of October 22, Cryptoticker notes, the final text was not yet in the Federal Register. Comptroller Jonathan V. Gould described the aim as “a clear, practical framework for payment stablecoin innovation, with strong standards for reserve backing, redemption, and risk management.”
One detail from our September 30 analysis is now settled. The Act takes effect on January 18, 2027, or 120 days after the final rules, whichever comes first. A final rule issued on October 21 puts the 120-day mark at February 18. So January 18 governs.
Who the rule binds, and who it skips
The OCC says the rule applies to national banks, federal savings associations, federal branches and their subsidiaries. It also reaches nonbank firms that want federal qualified issuer status, plus state qualified issuers where the OCC has authority. Foreign payment stablecoin issuers are inside the scope.
A shop, a freelancer or an API seller that receives USDC is on none of those lists. Our earlier guide to the Act reached the same conclusion: the law regulates who may issue the coin, not who may take it as payment.
The part left out matters as much. The release excludes Bank Secrecy Act, anti-money-laundering and OFAC sanctions rules. Those go to a separate rulemaking in coordination with Treasury, and Cryptoticker reports no announced timeline. Until they exist, the freeze and sanctions practices of each issuer are still set by that issuer. Our pieces on USDT sanctions risk and the Conduit v. Tether case explain what that means for a balance you hold.
Two choices the OCC made on yield and reserves
The Act bars an issuer from paying holders interest or yield solely for holding a coin. The February proposal went further and presumed that some arrangements with affiliates or third parties broke that ban. The final rule drops the presumption. Cryptoticker quotes the Bank Policy Institute: “The decision to omit the interest presumption replaces clarity with ambiguity.”
The American Action Forum's analysis, published October 22 by Thomas Kingsley, reads the change the same way. The OCC now relies on supervisory discretion and case-by-case enforcement to separate permitted transaction-based payments from prohibited yield. Kingsley writes that “firms should not have to discover the limits of a federal prohibition by guessing what a regulator might decide after the fact.”
For a merchant, the takeaway is simple. If a platform offers you a reward for holding or routing stablecoins, the rule does not tell you whether it is allowed. Keep the reward apart from the payment, as our OUSD rewards piece argued.
On reserves, the same AAF analysis says the OCC chose principles-based diversification standards plus two numbers: 5% of reserves in demand-available funds and a 40% cap on exposure to a single counterparty. It says these replaced stricter proposed requirements. Issuers must also hold reserves worth at least as much as their outstanding coins.
A worked example: the reserve limits on a $2 billion issuer
Take an invented issuer with $2,000 million of coins outstanding and $2,000 million in reserves. This is arithmetic on the two AAF figures, not data about any real issuer. Read the rule text before relying on how each limit is counted.
| Item | Limit reported by AAF | On $2,000 million |
|---|---|---|
| Reserves backing the coins | At least 1 to 1 | At least $2,000 million |
| Demand-available funds | 5% of reserves | $100 million |
| Exposure to one counterparty | 40% cap | $800 million |
| Counterparties needed if each sits at the cap | $2,000 million ÷ $800 million | 3 at minimum |
Two readings follow. First, the 40% cap limits the damage from one failed bank, but it does not remove it. At the cap, a single failure still touches $800 million, 40% of the pool. Second, 5% on demand is a small liquidity cushion. In a rush of redemptions, the other 95% has to be sold or matured.
A merchant sees neither number. What it sees is the time a balance sits in its wallet. If you convert or sweep receipts within a day, your exposure to an issuer problem is one day of sales, not a month.
Seven dates for a merchant's calendar
The US rule is one clock among several. A business that sells to both the US and the EU runs on at least two.
| Date | Event | Why a merchant cares |
|---|---|---|
| July 18, 2025 | GENIUS Act signed | Start of the US timeline |
| February 25, 2026 | OCC proposes its rule | Included the presumption on third-party yield |
| October 14, 2026 | EBA calls USDC a significant e-money token | EU supervision of USDC reserves moves to the EBA |
| October 21, 2026 | OCC final rule | Presumption dropped; AML rules deferred |
| November 12, 2026 | EBA takes over supervision of USDC | Applies to reserves, liquidity and recovery plans |
| January 8, 2027 | ESMA remediation deadline for non-MiCA stablecoins | EU-licensed firms stop serving legacy USDT exposure |
| January 18, 2027 | GENIUS Act and OCC rule take effect | US issuer standards apply |
Six things to finish before January 18
- Name the issuer of every token you accept. Write the issuer next to each token and chain in your payment settings.
- Decide what you hold and what you convert. Set a maximum balance and a sweep schedule, in days.
- Keep rewards and payments separate. Do not take a yield or rewards program whose status you cannot explain to your accountant.
- Ask your accountant how stablecoin receipts are recorded, since the rule says nothing on that.
- Put November 12 and January 18 in your calendar and read the Federal Register text once it appears.
- Keep the receiving address under your control. An issuer freeze still reaches a self-custody balance, which is why balance and time matter.
Where Payzum fits
Payzum is not an issuer, holds no reserves and never holds your funds. Customer payments settle to a wallet you control, and you can switch on auto-convert so accepted crypto settles as USDC or USDT. Our auto-convert guide shows how, and the USDT vs USDC comparison covers the choice itself.
Payzum charges 0.5% per processed sale, deducted from the amount received, plus on-chain network gas. If a customer pays 100, you receive 99.50 before gas. Payzum does not tell you which stablecoin to take and does not give legal advice.
Pushback we expect
“Does a federal rulebook make my USDC balance safe?”
It raises the floor for approved issuers on paper. A balance is still a claim on an issuer, so the time you hold it is the part you control.
“Should I wait until January 18 to accept stablecoins?”
The date marks when the issuer rules apply. Nothing in the OCC's description tells a business that gets paid to wait. Your own counsel should answer that for your case.
“Is USDT out in the US now?”
This rule does not say so. It lists foreign payment stablecoin issuers within its scope and does not name a token. Watch the Treasury rulemaking on anti-money-laundering and sanctions, which is where much of the open risk sits.
Frequently asked questions
What is the OCC GENIUS Act final rule?
It is the Office of the Comptroller of the Currency's rule implementing the GENIUS Act, issued October 21, 2026. It sets standards for payment stablecoin issuers on reserves, redemption, risk management, custody and audits, and takes effect January 18, 2027.
Does the OCC rule apply to merchants that accept USDC?
The OCC lists banks, federal branches, nonbank qualified issuers, state qualified issuers and foreign issuers. A business that receives USDC or USDT as payment is not on that list. Ask your counsel about your own case.
What did the OCC change about stablecoin yield?
It dropped a proposed presumption that some third-party reward arrangements break the ban on issuer yield. The OCC will now review them case by case, so the line between permitted payments and prohibited yield stays unclear.
What are the OCC's reserve limits?
The American Action Forum reports principles-based diversification standards plus 5% of reserves in demand-available funds and a 40% cap on exposure to a single counterparty. Issuers must hold reserves at least equal to outstanding coins.
How does Payzum relate to the GENIUS Act rule?
Payzum is not an issuer and holds no funds. Payments settle to a wallet you control, with optional auto-convert to USDC or USDT. Payzum charges 0.5% per processed sale, deducted from the amount received, plus network gas, and gives no legal advice.
Settle first, then decide what to hold
The OCC wrote its rulebook for issuers. Your side of the line is shorter: know the issuer, limit the time a balance sits, and keep rewards out of the payment. Book 20 minutes with our team and we will set up non-custodial settlement that fits that plan.
