What the GENIUS Act and the OCC say
The GENIUS Act prohibits permitted issuers from paying holders "any form of interest or yield (whether in cash, tokens, or other consideration) solely in connection with the holding, use, or retention" of a payment stablecoin. It says nothing explicit about payments made by exchanges, wallets or fintech apps.
The OCC's March 2026 proposal tried to close that gap with a rebuttable presumption: certain issuer arrangements with affiliates or related third parties that passed yield to holders would be presumed illegal. Its final rule, issued October 21, 2026, dropped the presumption. The OCC said it could be both too broad and too narrow, declined to define "interest" or "yield", and will apply the statute to the facts of each arrangement. Payments made on an issuer's behalf solely for holding are still likely prohibited; other third-party structures may not be.
What the CLARITY Act would change
The Senate Banking text of the CLARITY Act, built on a May 2026 compromise between Senators Tillis and Alsobrooks, extends the logic to "covered parties" such as exchanges. It would ban rewards paid solely for holding a payment stablecoin, or in a way economically equivalent to interest on a bank deposit, while allowing rewards for payments, transfers, staking, providing liquidity, governance and loyalty programs. The bill failed a 49-50 Senate vote on September 15, 2026 and is stalled.
The cashback precedent
The line regulators are drawing is not new. Credit card rewards were controversial when they spread: card issuers were paying customers without that money coming from deposits. They survived because they are tied to an activity, spending, rather than to a balance.
Stablecoin products are converging on the same model. Most stablecoin cardsalready pay cashback on spending rather than interest on balances: KAST pays 1.5% in dollars on the first $2,000 a month on its free plan, ether.fi Cash 3% on its free level, and MetaMask Card up to 1%. Expect more balance rewards to be reframed as activity rewards if the rules tighten.
The bigger shift: fintechs sharing the margin
Even where direct yield is restricted, money is fungible. A fintech that earns the interest margin on stablecoin balances can use it to cut prices elsewhere: free transfers, no trading commissions, better FX, or richer card rewards. That is how challengers like Robinhood and SoFi have competed for years, and stablecoins give the same economics to any global platform. This is the real reason banks fought so hard over rewards.
What it means for you
- Rewards on PYUSD and USDC are live today and variable; they can be cut at any time.
- Card cashback is the most durable form of stablecoin reward under every version of the rules.
- Compare any rate with a Treasury bill, about 4.05% in late October 2026. See current options in our stablecoin yield guide and how to invest in stablecoins.
