Clarity Act draft banning stablecoin yields triggers 20% Circle sell-off and broader regulatory jitters

Shares of Circle Internet Group (CRCL) plunged about 20% and Coinbase shares fell nearly 10% after reports that a draft of the Clarity Act could impose strict limits on stablecoin yield, spurring the market sell-off ^{[1] [2] [3]}.

The draft legislation from Senators Angela Alsobrooks and Thom Tillis would bar rewards on passive stablecoin balances and prohibit structures described as “economically equivalent to interest,” a stance that goes further than the GENIUS Act enacted last year, which restricted issuer-paid yields but left room for third-party arrangements ^[1].

News coverage noted the sell-off coincided with intensified regulatory attention: Circle reported its worst trading day on the move, and the CFTC is forming a task force to oversee crypto, AI and prediction markets, signaling heightened oversight across multiple fronts ^[4].

Legislative negotiations are ongoing—bank representatives were reported to be reviewing compromise language on stablecoin yield, and some outlets said the odds of the Clarity Act passing in 2026 decreased as that review proceeded ^[5].

Separately, Circle has urged the European Union to ease proposed rules as stablecoin growth stalls in Europe, reflecting industry concern about regulatory constraints on stablecoin adoption and product offerings ^[6].

Regulatory proposals targeting stablecoin yield and concurrent industry and bank negotiations are driving immediate market volatility for stablecoin issuers; ongoing legislative review and rulemaking in the U.S. and EU will be key developments to monitor ^{[1] [5] [6]}.
