Senators Cynthia Lummis and Thom Tillis publicly stood behind the stablecoin yield language in the CLARITY Act on Monday after a coalition of five banking trade groups attacked the compromise as inadequate. The next two weeks will decide whether the deal holds.
Senators Cynthia Lummis and Thom Tillis publicly defended the stablecoin yield language in the CLARITY Act on Monday, after five major US banking trade groups jointly attacked the compromise as inadequate. The push came less than a week after Tillis and Senator Angela Alsobrooks released the agreement that crypto trade groups had spent months negotiating.
The text the senators struck does two things at once. It bars firms from paying anything that economically or functionally resembles bank deposit interest on a stablecoin balance, and it carves out room for "bona fide activities or bona fide transactions" — things like cashback rewards on transactions and on-chain incentives — that look more like credit-card points than yield. Crypto firms get to keep their reward programmes; banks keep the rule against stablecoin issuers paying for raw deposits.
Five banking trade groups did not see it that way. The American Bankers Association, the Independent Community Bankers of America and three peer organisations issued a joint statement on Monday calling the compromise insufficient, saying the proposed language "falls short of prohibiting the payment of yield and interest on stablecoins." Their estimate was unsubtle — yield-earning stablecoins, the groups argued, could pull deposits out of the banking system and reduce all consumer, small-business and farm loans by one-fifth or more.
Lummis answered the same day. "This finalised, bipartisan text is the culmination of months of hard work to deliver a compromise on yield we can all live with," she wrote. "We are closer than ever to getting the Clarity Act across the finish line." Tillis followed with a more pointed line — that he and Alsobrooks had "worked in good faith with all sides throughout this process to encourage compromise and to avoid letting the perfect become the enemy of the good." On Tuesday he added, in response to the banking trade groups, that "we respectfully agree to disagree."
That defence matters because of the calendar. The Senate's Memorial Day recess starts on May 21. Banking Committee chair Tim Scott has not scheduled a markup. Without the senators publicly holding the line, every day before recess hands banking lobbyists another chance to talk the compromise back open. The Lummis–Tillis stablecoin compromise is not the same thing as the stablecoin yield deadlock that Coinbase claimed had broken last weekend — it is the chapter that decides whether anything Coinbase claimed actually sticks.
Crypto trade groups have lined up behind the deal. Coinbase, Circle and other firms publicly endorsed the language and asked the Senate Banking Committee to advance the bill. Their motive is straightforward: rewards programmes built on stablecoin balances are how most US-listed crypto firms intend to compete with banks for retail deposits, and the new text preserves the architecture they have already built. Stripping the carve-out at the last minute would force them to redesign products that have already shipped.
The banking groups' specific concern is more technical than the headline suggests. They argue the line between a "bona fide activity" reward and economic yield is too easy to engineer around. A reward paid in proportion to balance, even if formally tied to a transaction or a referral, looks indistinguishable from a deposit-style payment once it scales. Galaxy Digital's policy team flagged the same problem at a Bitcoin 2026 panel last week, when Galaxy's head of US policy called 2026 passage a coin flip. The compromise narrowed the odds. It did not settle them.
There is also the Agora question. A handful of issuers, including Agora, which filed for an OCC trust charter last week, are designing products that depend precisely on the boundary the new text draws. If the markup tightens the language, those filings get rewritten before they ever clear. If it softens, the banking lobby has an argument to take into the House.
The numbers underneath the fight have moved. Circle's stock closed up 19.9% on Friday after the compromise text dropped, the largest single-day move in the company's listed history. USDC supply sits near $77.3 billion, up 73% year-on-year; Tether's USDT remains the larger pool at roughly $187 billion, up 36%. Both issuers are effectively designing product strategy around what the markup says next.
Markup, when it comes, will happen in the Senate Banking Committee. Scott has not given a date. Recess begins May 21.
