Bitcoin surged through $87,000 on Monday, September 21, reaching its highest level in roughly eight months and extending a sharp reversal from last week’s regulatory and macro-driven selloff. BTC traded around $86,958 late Monday afternoon in the U.S., up more than 7% over 24 hours, after briefly crossing the $87,000 threshold. The move leaves Bitcoin more than 15% above the lows around $75,000 reached on September 15.
The recovery is particularly notable because it has occurred despite several recent headwinds. The Federal Reserve raised interest rates last week, while the Senate failed to advance the CLARITY Act after the legislation fell short of the 60 votes needed to proceed. Rather than extending those losses, Bitcoin reversed sharply as improving macroeconomic conditions, renewed institutional demand and forced buying from short sellers changed the market’s momentum.
ETF Demand Returns as Macro Pressure Eases
U.S. spot Bitcoin ETFs recorded significant outflows earlier last week, losing approximately $746 million across September 15 and 16. Flows subsequently reversed, with about $159.5 million returning on September 17 and approximately $433 million on September 18. Fidelity’s FBTC accounted for roughly $311 million of Friday’s inflows, while BlackRock’s IBIT attracted around $108 million. The late-week recovery left the funds with approximately $6 million of net inflows across the five-session period despite the heavy withdrawals earlier in the week. Macro conditions also became more supportive on Monday. Oil prices fell nearly 3%, while the benchmark U.S. 10-year Treasury yield dropped back below 5%. Lower bond yields generally improve conditions for risk assets because they reduce the relative attractiveness of holding risk-free government debt.
U.S. equities rallied alongside Bitcoin, with the Nasdaq reaching a record close as technology and semiconductor stocks strengthened. Bitfinex analysts said the initial Bitcoin recovery appeared primarily driven by spot demand rather than excessive leverage. Open interest measured in Bitcoin terms declined as prices rose, while perpetual futures funding remained relatively neutral.
Short Liquidations Turn Recovery Into a Squeeze
Once Bitcoin broke through key resistance levels, derivatives positioning amplified the rally. More than $750 million of crypto positions were liquidated over a 24-hour period as Bitcoin initially moved through $85,000, according to CoinGlass data cited by The Block. Approximately $648 million of those liquidations were short positions. As Bitcoin moved closer to $87,000, liquidation estimates across the wider crypto market climbed further, creating a feedback loop in which short sellers were forced to buy assets to close losing positions.
The rally has also lifted crypto-linked equities. Strategy, Coinbase and Robinhood all gained as investors increased exposure to companies whose revenues or balance sheets are closely connected to digital assets. Bitcoin nevertheless remains well below its October 2025 all-time high near $126,000. Even after Monday’s rally, the cryptocurrency is still roughly 30% below that peak. The speed of the latest recovery is therefore significant but does not by itself establish a return to previous highs.
What has changed most clearly is market positioning. Bitcoin absorbed a Federal Reserve rate increase, the CLARITY Act setback and heavy ETF withdrawals without extending last week’s decline. When spot demand subsequently returned, a market positioned heavily for further weakness was vulnerable to a rapid short squeeze. Bitcoin’s break above $87,000 now puts the psychologically important $90,000 level back into focus, while sustained ETF demand and Treasury yields are likely to remain important indicators of whether the rebound can continue.
