Bitcoin has broken above $81,000 for the first time since May and briefly touched $82,000, extending a rally that gained about 25% in August as Federal Reserve rate-hike concerns eased and U.S. long-term Treasury yields fell. Fed Governor Christopher Waller said he could support holding rates steady if upcoming inflation data confirm easing price pressures, tempering hawkish signals from Fed Chair Kevin Warsh’s Jackson Hole speech and helping restore risk appetite. The 30-year Treasury yield dropped from an intraday high of 5.337% in mid-August to 5.246%, while analysts also pointed to the U.S. Treasury’s long-term bond buyback program as medium-term support for digital assets. Bitcoin remains roughly 35% below its October all-time high of $126,000 and about 7–11% lower on the year, with Noelle Acheson arguing recent price action shows the crypto winter is ending and Bernstein’s Gautam Chhugani reiterating a $150,000 year-end target while yields stay capped. Spot Bitcoin ETF flows briefly saw a 7-day average inflow as high as $290 million a day, though weekly outflows underscore instability, and altcoins joined the rebound with Ethereum at $2,506 and Ripple at $1.44. Markets now look to the September 15–16 FOMC meeting, September seasonality, holder profit-taking near $83,000–$86,000, and whether price can hold above $82,000 with steadier ETF demand.
