Cryptocurrency prices and crypto-related stocks fell on Sept. 15 after the US Senate voted 49-50 against advancing the CLARITY Act on a procedural cloture motion. Equities tied to the crypto sector recorded steeper percentage losses than digital assets themselves, with several closing down more than 10%.
Bitcoin (BTC) declined approximately 2.85% over 24 hours, trading at $75,756 as of 10:20 pm ET on Sept. 15. Ethereum (ETH) dropped 4.5%, XRP fell 9.2%, and Solana (SOL) declined 5.4%. The GMCI 30 Index, which tracks the top 30 cryptocurrencies by market performance, closed down 4.16%.
Stocks Absorb Steeper Losses
Coinbase fell more than 10% on Sept. 15, and USD Coin (USDC) issuer Circle dropped 11.4%. Michael Saylor’s Strategy declined 5.4%, while Ether treasury firm Bitmine lost 8.4%. All four stocks began selling off around 2:30 pm ET and hit session lows by 2:50 pm, at roughly the same time the Senate result was announced. Each extended its losses in after-hours trading.
Wincent Senior Director Paul Howard said the vote reflected pressure from banking incumbents protecting their existing market position rather than any broader rejection of digital assets. He noted that the Senate debating crypto market structure at all represented a notable development for the industry.

Rate Environment Seen as Bigger Driver
Analysts who spoke to The Block said the legislative failure did not alter the fundamental conditions shaping the crypto market. Justin d’Anethan, head of research at Arctic Digital, described the bill’s defeat as “nothing truly structural,” noting that Bitcoin had reached its prior all-time high before the CLARITY Act existed. He said institutional investors appeared to treat the result as a timeline adjustment rather than a reason to exit positions, and that monetary conditions would remain the primary price driver.
BTC Markets crypto analyst Rachael Lucas said the current cycle has been rates-dependent rather than driven by regulatory developments. She identified three factors to monitor: whether the Federal Reserve’s anticipated rate decision signals a longer tightening path, whether ETF inflows resume, and whether a regulatory path emerges that does not require 60 Senate votes. Lucas said Bitcoin reclaiming its Sept. 15 opening price of $78,189 would be the clearest early signal that markets had moved past the legislative result.
Lucas also noted Bitcoin’s mining hash rate sat 12% below its December 2025 peak, with major miners shifting capacity toward AI computing. The ETH/BTC ratio climbed more than 25% in the third quarter of 2026, and privacy coins rose 213% since Bitcoin’s October peak, which she said reflected rotation within the market rather than a broad exit. D’Anethan said a fourth-quarter recovery depended more on the interest rate environment than on any congressional outcome.
