The U.S. Senate failed to advance the House-passed Digital Asset Market CLARITY Act in a procedural vote, leaving the proposed federal framework for digital-asset regulation eligible for reconsideration but with uncertain near-term prospects. The motion fell short of the 60 votes needed for cloture amid disputes over ethics, stablecoin yield payments, illicit finance, consumer protection and the division of authority between the Securities and Exchange Commission and Commodity Futures Trading Commission. Bitcoin's decline began before the September 15 vote, Santiment said, complicating claims that the bill's defeat alone triggered the selloff. BTC had already declined about 5% from its September 3 peak before the vote, while it lost a further 1.7% during the voting period, accounting for less than one-quarter of the roughly 7% pullback. Santiment said its weighted social sentiment indicator reached a 30-day high on September 14 and social-media mention volume reached a 14-day high on September 15, with sentiment remaining positive after the vote. Bitcoin later stabilized near $75,900 following a broader market decline as investors weighed the legislative setback, rising Treasury yields, geopolitical tensions and the Federal Reserve's scheduled policy decision. Santiment said the cause of Bitcoin's decline during the 12 days before the vote remained difficult to identify. The Senate result leaves crypto firms dependent on SEC and CFTC action under existing authority while lawmakers consider whether to revive the legislation.
