Bitcoin recovered its 50-week moving average and briefly exceeded $87,000 after falling below $76,000 following the Federal Reserve's 0.25 percentage-point rate increase and the CLARITY Act's failed Senate procedural vote. Wintermute said markets had moved past those two catalysts, while year-end call buying increased for the first time since November 2025 and Bitcoin and Ether broke above their range ceilings within several hours. Bitcoin traded at $86,423 on Tuesday, supported by spot buying, ETF flows, short liquidations and renewed investment of idle client cash, although further Fed tightening, revised inflation data, subdued follow-through and the Sept. 25 options expiry could still increase volatility.
