Bitcoin Jumps 8% on Aug. 19 as $1.1B–$1.3B in Shorts Get Wiped Out

Bitcoin surged 8% on Aug. 19, climbing from the low $64,000s to an intraday high of $69,749 for its strongest one-day gain since February 2026. The move was fueled by a classic short squeeze: crowded bearish bets were hit with margin calls at the same time, triggering rapid forced buying. In roughly one hour, liquidations in short positions totaled an estimated $1.1 billion to $1.3 billion. Across the broader crypto derivatives market, reported short liquidations over the subsequent 24 hours reached as much as $2.7 billion, ranking among the largest liquidation events since industry tracking began in 2021. More than 100,000 traders were affected. The squeeze followed weeks of subdued trading. Bitcoin had been range-bound between about $61,500 and $65,000, a pattern that often dulls retail participation while encouraging leveraged shorts to lean on nearby support. As positioning built for a break below $61,500, fresh buying flipped the script. What started as a modest rise escalated into a sharp rally as stop-outs and forced liquidations cascaded. Macro conditions also leaned supportive. The US Treasury recently said it plans to double buybacks of longer-dated bonds, a shift that pushed 30-year yields lower. Declining long-term yields typically improve the relative appeal of risk assets, and Bitcoin has increasingly traded like a high-beta risk asset. On the flow side, US spot Bitcoin ETFs took in about $297.6 million of inflows earlier in the week. While not exceptional on its own, the figure marked a pickup from prior weeks and pointed to firmer institutional demand as the squeeze developed. The day also echoed an earlier market extreme. Bitcoin's best session since February 2026 is notable because that February selloff was driven by an inverted version of the same leverage dynamic, with long positions liquidated en masse. Together, the episodes underscore how derivatives positioning can amplify moves, with leverage acting as a key accelerant. For markets, the immediate implication is mechanical: a liquidation wave of this scale flushes a sizable portion of leveraged short interest, potentially reducing near-term forced selling from short-covering dynamics. Attention now shifts to institutional demand. If spot Bitcoin ETF inflows build from the roughly $297.6 million pace, it would suggest follow-through buying beyond a one-off short-covering spike.
