Congress thought it settled the stablecoin yield question when the GENIUS Act barred issuers from paying interest on their tokens. It did not. The statute banned issuer-paid yield and said nothing about affiliates. Exchanges like Coinbase drove a truck through the gap by paying "rewards" on customer balances, and the OCC's February 2026 rulemaking is a bureaucratic attempt to un-write a hole the drafters cut themselves.
A loophole written on purpose, patched by presumption
The OCC's proposed fix is a rebuttable presumption: any coordinated arrangement between an issuer and an affiliate to pay holders yield is treated as a prohibited yield scheme unless the parties prove otherwise. That is regulation by suspicion. It asks compliance officers to disprove intent, invites years of comment-letter warfare, and still cannot answer the core question of why a dollar sitting in a stablecoin should be legally forbidden from earning what a dollar in a money-market fund earns freely.
The bank-deposit-drain argument is thin
Banks insist yield-bearing stablecoins would siphon deposits and choke lending. The numbers say otherwise. The Council of Economic Advisers found that a full prohibition would raise aggregate bank lending by roughly $2.1 billion, a rounding error of about 0.02 percent, while imposing a net welfare cost on savers. When the pro-ban case rests on a benefit that vanishes under a microscope, the policy is not about financial stability. It is about protecting an incumbent's margin.
- Scale: stablecoins outstanding topped $281 billion by March 2026, large enough that the rules of the road actually matter.
- Asymmetry: banks may pay interest on deposits; forbidding a competitor from doing the same is textbook anticompetitive shelter.
- Enforceability: a rebuttable presumption polices form, not substance, and clever structuring will migrate offshore or into new affiliate wrappers.
Why the ban cannot hold
Prohibitions that fight economics rather than fraud tend to lose. Depositors will chase yield wherever it is legal, and if domestic affiliates are boxed in, the yield simply reappears as points, cashback, or foreign-issued tokens U.S. users hold anyway. The OCC will find itself perpetually a step behind the product designers.
The honest path is disclosure, not prohibition: require issuers and affiliates to segregate reserves, publish attestations, and label yield as a return on the affiliate's balance sheet rather than a promise from the token. Let savers choose with open eyes.
The precedent that should worry everyone
If regulators can suppress a competing payment rail because banks fear deposit competition, the principle generalizes to any fintech that threatens net interest margin. That is not prudential supervision. It is industrial policy dressed as consumer protection, and it deserves the skepticism this column is happy to supply.
The GENIUS Act's drafters left a Coinbase-shaped hole. The fix is not a presumption that treats every reward as guilty until proven innocent. It is to admit that in a world of programmable dollars, the market clearing price of holding cash is not zero, and no rulemaking will make it so.
