Section 404 of the CLARITY Act bans stablecoin yield for idle balances but allows activity-based rewards. The Tillis-Alsobrooks text, the bank fight and DeFi impact.

The CLARITY Act's stablecoin yield rule, Section 404, would stop crypto platforms paying interest-like rewards simply for holding a stablecoin, while still allowing rewards for activity such as payments, providing liquidity, posting collateral, staking or governance. It is the compromise Senators Thom Tillis and Angela Alsobrooks released on 1 May 2026. Because the CLARITY Act failed a Senate cloture vote on 15 September 2026, Section 404 is not law as of 2 October 2026, and platform stablecoin rewards remain legal in the US for now.
This guide focuses on that one question: what the yield text says, why banks fought it, and what it would mean for stablecoin yield in DeFi. For the bill as a whole, including the SEC/CFTC split and the Senate timeline, read the CLARITY Act explained.
The GENIUS Act, the US stablecoin law signed in July 2025, already bars stablecoin issuers from paying holders "any form of interest or yield" solely for holding, using or retaining a payment stablecoin (Section 4(a)(11), as quoted by Astraea Law). It says nothing direct about third parties, such as exchanges, that hold stablecoins for customers.
That gap is how platform rewards work. An issuer earns interest on the Treasury bills and cash behind its coin, shares part of it with a distribution partner, and the partner passes some on to users as "rewards". Circle averaged $76.5 billion of USDC in circulation in Q2 2026 and earned $668 million of reserve income, while Coinbase made $292 million from stablecoins, about a quarter of its revenue, according to 24/7 Wall St.
Banks call this a loophole. If a dollar stablecoin pays a reward close to a savings rate, customers might move money out of bank deposits, which banks lend out. Crypto firms say rewards are a normal part of competing for users. The CLARITY Act was the first real attempt to draw the line.
Based on the reported Senate Banking text, as summarised by Astraea Law and CoinDesk:
Two details surprise most readers. First, permitted rewards "may be calculated by reference to a balance, duration, tenure, or any combination". So a reward can still scale with how much you hold, provided it is tied to a genuine activity. Second, the text includes a good-faith safe harbor for firms relying on the rules.
The list of activities regulators would have to publish includes, according to Astraea Law:
| Example | Likely treatment under the text |
|---|---|
| A flat rate paid on USDC that sits untouched in an exchange account | Banned: paid solely for holding, and deposit-like |
| Cashback when you pay a merchant in a stablecoin | Allowed: tied to a transaction |
| Rewards for supplying stablecoins as market-making liquidity | Listed as a permitted activity |
| Rewards for posting stablecoins as collateral | Listed as a permitted activity |
| A paid membership tier that adds rewards to balances | Unclear: "subscription" programmes are listed, but the deposit-equivalence test still applies |
The table reflects the reported text, not final rules. The "economically or functionally equivalent" test is a judgement call. A programme that is formally tied to activity, but in practice pays everyone a steady rate on their balance, could still fail it. That is why both sides cared so much about who writes the rules and how.
Banking groups opposed the compromise from the start, and the gap never closed:
The crypto industry largely backed the May text. Coinbase's chief legal officer, Paul Grewal, said it "preserves activity-based rewards tied to real participation on crypto platforms" (CoinDesk).
Section 404 lives inside the CLARITY Act, so it shares the bill's fate. The Senate voted 49–50 on 15 September 2026 against cloture on the motion to proceed, short of the 60 votes needed. Ethics provisions were the main reason, with the stablecoin yield dispute unresolved in the background (FinTech Weekly). A motion to reconsider keeps the bill available, but the window for 2026 is narrow.
What that means in practice, as of 2 October 2026:
Most DeFi stablecoin yield already comes from activity rather than idle holding. You earn because you are doing something with the coin:
Two caveats. First, Section 404 binds "digital asset service providers". Whether a particular non-custodial protocol, front end or developer counts as one would depend on the bill's definitions and on rulemaking, and the reported text doesn't settle that. Second, the money that flows into DeFi often starts on a centralised exchange, and those exchanges are clearly covered. Tighter rules on idle-balance rewards at exchanges could push yield-seeking users towards on-chain activity, or towards rewards designed around activity.
Whatever the law says, activity-based yield is not risk-free. LP positions carry impermanent loss and smart-contract risk, lending carries liquidation and bad-debt risk, and stablecoins can depeg. See how to earn yield on stablecoins and stablecoin depegs explained.
JewelSwap is a non-custodial protocol on MultiversX, Sui and Radix. Its stablecoin yield on Sui comes from activity: farms that use Scallop lending and Cetus liquidity, where returns come from borrowing, supplying and liquidity incentives rather than from a rate paid on idle balances. Returns are variable and carry the risks above. The stablecoin yield farming guide explains how this kind of strategy works.
Section 404 would ban crypto platforms from paying interest or yield solely for holding a payment stablecoin, or anything economically equivalent to bank deposit interest. It would allow rewards tied to genuine activity. The bill has not passed, so the ban is not in force as of 2 October 2026.
It is the stablecoin rewards text Senators Thom Tillis and Angela Alsobrooks released on 1 May 2026. It bans passive, deposit-like yield on stablecoin balances while preserving activity-based rewards such as payments, liquidity provision, collateral, staking and governance.
Yes, for crypto platforms. No federal law currently bans an exchange from paying rewards on stablecoin balances. Under the GENIUS Act, which takes effect no later than 18 January 2027, stablecoin issuers themselves can't pay interest to holders.
Banks argue that interest-like rewards could draw deposits out of banks and reduce lending. ICBA estimates $1.3 trillion of deposits could move over time. Banking groups asked senators to tighten the text and called the Treasury circuit breaker insufficient.
Probably less than exchange rewards. Liquidity provision, posting collateral and staking are on the text's list of permitted activities. Whether a given non-custodial protocol counts as a covered service provider would depend on definitions and rulemaking.
Under the reported text, yes, if the reward is tied to a bona fide activity. Permitted rewards may be calculated by reference to balance, duration or tenure. A reward paid only for holding would still be banned.
