The OCC Just Wrote the Rule on Your 4% Stablecoin Yield. It Won't Say If Coinbase's 3.75% on USDC Is Legal

4%. That’s what PayPal pays on PYUSD. Coinbase One pays 3.75% on USDC, and Kraken+ pays up to 4.5% on USDG, per CoinDesk.

On Tuesday, the U.S. banking regulator published the final rule governing exactly this kind of payout. Asked whether those programs are legal, an OCC official said:

“We will just let the market develop and address it as it comes.”

That’s the official answer for a market of billions of dollars in stablecoins.

What Happened

On October 21, 2026, the Office of the Comptroller of the Currency issued its final rule implementing the GENIUS Act, the stablecoin law signed in July 2025. It’s the first core GENIUS rulebook any federal banking regulator has finalized. The Fed, FDIC and Treasury have only proposals out.

The rule and the law both take effect on January 18, 2027. That’s 89 days away.

It’s also late. The statute set a mid-year deadline for regulators, and per CoinDesk, none of them met it. As we covered in July, the clock ran out on July 18. The OCC’s rule landed about three months after that.

Comptroller Jonathan V. Gould said in the OCC’s release:

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

The rule covers permitted payment stablecoin issuers and foreign issuers under OCC jurisdiction, plus certain custody activities at OCC-supervised banks. It drew what the OCC called “hundreds of comments.”

The Part Everyone Is Fighting About: Yield

The GENIUS Act bans issuers from paying interest or yield “solely in connection with the holding, use, or retention” of a stablecoin. The final rule keeps that ban.

What changed is the fine print:

• The February proposal is gone. In February, the OCC proposed treating certain deals between issuers and affiliates or third parties as presumed violations. That would have hit the classic setup where an issuer shares reserve income with an exchange and the exchange pays users “rewards.” The final rule drops it. In the rule’s words, “the OCC does not believe that it is appropriate to impose a rebuttable presumption.”
• Case-by-case review instead. The OCC says it keeps the authority to go after attempts to evade the ban. It will judge each arrangement on its facts.
• No free pass for existing programs. From the rule: “The OCC declines to presume that rewards programs that predated the GENIUS Act comply with the GENIUS Act.”
• No waiting for Congress. Commenters asked the OCC to hold off until the Clarity Act, the market-structure bill that could rewrite the yield language, was resolved. Clarity failed to advance in a key Senate vote last month. The OCC’s reply: “Unless and until such legislation passes, the OCC must implement the GENIUS Act’s yield prohibition, as enacted.”

So the rule doesn’t bless exchange rewards, doesn’t ban them, and doesn’t say how anyone would find out which they are.

Banks Are Furious

The banking lobby wanted the presumption. Its fear is that if Coinbase can pay 3.75% on a dollar token, savers pull deposits out of banks.

Paige Pidano Paridon of the Bank Policy Institute:

“The decision to omit the yield presumption replaces clarity with ambiguity and puts the banking system and its customers at risk of deposit flight.”

BPI also said the rule “fails to establish a transparent process” for those case-by-case calls.

Rob Nichols, CEO of the American Bankers Association, said it more bluntly: “The result is a final rule that will preserve the status quo for crypto platforms.”

Treasury Secretary Scott Bessent went the other way on X: “The GENIUS Act marks a watershed moment in American finance.”

The Rest of the Rulebook

Yield got the headlines, but the rule also sets the basics an issuer has to build before January:

• Reserves at least equal to outstanding stablecoins, under a “principles-based” approach to diversification and concentration, plus minimum daily liquidity and limits on exposure to any single counterparty
• Redemptions generally processed within two business days, per Cointelegraph
• Changes to the OCC’s capital and prompt-corrective-action rules, including a capital and operational backstop for issuers
• Separate bulletins on waivers and applications and on revised reporting forms

What’s not in it: Bank Secrecy Act, AML and sanctions rules. Those are coming in a separate rulemaking with Treasury. The OCC also hasn’t said when it will start processing issuer applications. It will “announce separately.”

Why This Matters for Crypto Jobs

Compliance teams now have something real to build against. Proposals don’t ship products. A final rule does. Every bank or fintech planning a federal stablecoin charter has 89 days to map reserves, redemptions, capital and reporting to actual rule text. That’s work for regulatory counsel, compliance analysts and treasury ops people who can read a 1:1 reserve requirement and turn it into daily controls.

“Case-by-case” means lawyers. No presumption and no safe harbor means every exchange rewards program has to defend itself on its facts. Expect exchanges and issuers to lean on policy, legal and product-compliance staff to restructure rewards so they can survive OCC review, whether that’s activity-based rewards, subscription bundles like Coinbase One and Kraken+, or something new.

The AML half isn’t written yet. With BSA, AML and sanctions rules still to come from Treasury, issuers are building half a compliance program now and guessing at the other half. People with both bank-grade AML experience and on-chain monitoring skills will be in demand.

Watch the Fed and FDIC. Which regulator an issuer answers to depends on its charter and deposit insurance status. Firms will need people tracking several rulebooks at once, and the OCC version is only the first one finished.

The Bottom Line

Banks wanted a line saying stablecoin rewards are illegal until proven otherwise. They didn’t get it. Crypto wanted a line saying existing programs are fine. It didn’t get one either.

The ban on issuer yield stands. Whether your 3.75% is a “reward” or banned “yield” will be decided one program at a time, by a regulator that says it will “address it as it comes.”

Effective date: January 18, 2027. The fight over what counts as yield starts now.
