Bitcoin Holds Near $77,500 as Spot ETFs Snap Three-Week Inflow Streak Ahead of Fed Decision

Bitcoin traded at $77,666, up 0.5% over the past 24 hours, according to CoinGecko, while Ether was little changed at $2,511.70, down 0.4%. Both assets have been rangebound over the past week as traders wait on two catalysts: a Senate procedural vote on the CLARITY Act scheduled for Tuesday, after Republicans released a revised version over the weekend with an ethics proposal reportedly endorsed by President Trump, and the Federal Reserve's policy decision on Wednesday. Treasury yields near 4.97% and Brent crude above $107 a barrel have kept pressure on risk assets, a dynamic that has weighed on crypto sentiment for much of the past two weeks.

US spot Bitcoin ETFs recorded $462.7 million in net outflows across the four trading sessions from September 8 to 11, according to Farside Investors data, ending a three-week streak of net inflows. Thursday, September 10 accounted for the bulk of the withdrawal at $282.7 million, the largest single-day outflow since July. ARK 21Shares' ARKB led redemptions with $164.3 million pulled on that day alone, while Grayscale's GBTC shed $156.3 million across the four sessions. BlackRock's IBIT was comparatively resilient, posting a small inflow on September 8 before turning slightly negative later in the week. Despite the reversal, Bitcoin ETFs remain net positive for September as a whole, with roughly $307.3 million in cumulative inflows through September 12, following the $3.34 billion that flowed in between August 19 and September 4 as Bitcoin rallied from around $62,000 toward $82,000.
