Circle (CRCL) Stock Drops 20% as Stablecoin Yield Restrictions Rattle Crypto Markets

Shares of Circle, the company behind the USDC stablecoin, plunged 20% on Tuesday after a draft version of proposed U.S. stablecoin legislation sparked concerns over potential limits on yield payments. The sharp decline snapped a remarkable rally that had seen the stock surge more than 100% over the prior weeks. Crypto exchange Coinbase, which shares revenue tied to USDC, also fell nearly 10% on the news.

The selling pressure was triggered by the latest draft of the Clarity Act, which analysts say could ban rewards offered simply for holding stablecoins. Mizuho analyst Dan Dolev warned the legislation may prohibit any yield structure that resembles a bank deposit, including the pass-through model Circle and Coinbase currently use. Under that arrangement, Circle earns interest on USDC's reserve assets and distributes a portion to Coinbase, which then funds user rewards. The new draft targets anything "economically equivalent to interest," potentially dismantling that entire incentive structure.

Critics argue this weakens a core part of the bull case for USDC as a store-of-value asset. Adding competitive pressure, rival stablecoin issuer Tether announced it hired a Big Four accounting firm to audit its USDT reserves, a move that could strengthen its credibility with institutional investors and chip away at USDC's market position.

Despite the steep single-day selloff, most analysts are urging calm. Several describe Tuesday's reaction as an overreaction driven by headline risk rather than fundamental deterioration. Circle still holds roughly 30% of the stablecoin market, which analysts project could grow tenfold over the next four years. The company's stock remains up more than 30% year-to-date even after the drop. Analysts also note that alternative incentive structures, such as loyalty programs, could effectively replace traditional yield offerings and keep USDC competitive in the evolving digital asset landscape.
