Bitcoin fell 2.39% to $76,314 on September 15 as the Senate prepared for a 2:15 p.m. ET cloture vote on the Digital Asset Market Clarity Act and the Federal Reserve was expected to announce its first interest rate increase in three years. The bill would distinguish digital commodities from securities and divide oversight between the CFTC (U.S. derivatives regulator) and SEC (U.S. securities regulator). It passed the House of Representatives 294-134 in July 2025 and cleared the Senate Banking Committee 15-9 in May 2026, but needs 60 votes to overcome a filibuster. A 635-page draft containing 126 changes was released on September 14, leaving senators roughly 24 hours to review it. The Federal Reserve was expected to raise its target rate by 25 basis points, taking the range to 3.75% to 4%. Passage would create the first comprehensive federal framework for digital-asset regulation in the United States, while a prolonged tightening cycle could continue pressuring Bitcoin and other risk assets. The source says meaningful price discovery would begin after 2:15 p.m. ET, when the Senate outcome and the Fed's intentions become known within hours of each other.
