Why is Bitcoin (BTC) up 5.22% Today, September 22, 2026? Heavy Short Covering and ETF Demand Drive BTC Toward $87K

Bitcoin rose 5.22% to ~85,678 amid heavy short covering, with ~585M in BTC derivatives liquidations and 60.60B in turnover, signaling a positioning-driven move with broad participation. Supportive macro inputs (lower oil and softer Treasury yields) improved risk appetite, while recent U.S. spot Bitcoin ETF inflows (~433M) strengthened spot demand. Near-term focus is on whether post-squeeze buying sustains momentum.
