Bitcoin Hits $78K: Inside the Record $1 Billion Short Squeeze Driving the August Rally Bitcoin tore through $70,000 and pushed toward $78,000 this week after more than $1 billion in short positions were liquidated in the space of roughly one hour, marking one of the fastest and most violent squeezes the crypto derivatives market has seen since 2021. The move, which began late on August 19 and accelerated through August 20, has reshaped what had been a listless, range-bound summer into one of the sharpest risk-on rallies of the year.

What triggered the squeeze The spark came from an unlikely source: the U.S. Treasury. Officials announced plans to at least double the size of long-dated bond buyback operations, raising the maximum per operation from $2 billion to $4 billion, as part of an effort to calm a bond market where 30-year yields had spiked to 5.337%, their highest level since 2007. The announcement pulled yields back sharply and weakened the dollar, creating exactly the kind of liquidity-friendly backdrop that scarce, risk-sensitive assets like Bitcoin tend to respond to.

That macro shift was enough to flip sentiment. Traders who had spent six weeks positioned for a deeper drawdown were suddenly caught leaning the wrong way, and as Bitcoin began climbing through key resistance levels, exchanges started force-closing those bets automatically.

How the squeeze fed on itself A short liquidation is mechanical rather than emotional. When a trader borrows to bet on falling prices and the price rises instead, the exchange closes the position to cover the loan — and that forced buy-back adds real demand to the market. Stack enough of them in sequence and the effect compounds: each liquidation nudges the price higher, which triggers the next batch of shorts, and so on.

That's precisely what unfolded. According to CoinGlass data, more than $1 billion of Bitcoin short positions alone were wiped out in about an hour, while total crypto short liquidations across the 24-hour window climbed past $1.7 billion — the second-largest such event on record, trailing only the $2.47 billion liquidation seen during the October 10, 2025 crash. Bitcoin accounted for roughly $1.65 to $1.68 billion of that figure depending on the data window measured, with the broader market shedding over $3 billion in bearish bets across the two-day stretch. Ether wasn't spared either, jumping nearly 18% in 24 hours as its own shorts were flushed out.

The scale of forced buying pushed Bitcoin from the mid-$60,000s through $69,000, then $72,000, with several trading desks noting intraday prints as high as $72,500. Momentum has since carried the conversation toward the $78,000–$79,500 zone as the next test, contingent on whether fresh demand can pick up where the forced buying left off.

Why this matters beyond the price chart For investors, the episode is a reminder of how leverage cuts both ways. A market that spent weeks in a fear-dominated, low-conviction range flipped to greed almost overnight — the Fear and Greed Index moved from 41 to 59 in a single session, according to tracked readings. That kind of swing tends to draw in momentum traders and sideline capital simultaneously, which is part of why squeezes like this one can extend further than the initial trigger would suggest.

There's also a genuine demand story layered underneath the mechanical one. U.S. spot Bitcoin ETFs pulled in $297 million on August 17, $189 million on August 18, and a much larger $517 million on August 19, with weekly inflows reaching roughly $1.6 billion. That's meaningful because it suggests at least part of the rally isn't purely short covering — real allocators were adding exposure even as the squeeze was unfolding.

At the same time, on-chain data shows more than 44,000 BTC moving to exchanges since the rally started, typically a signal that some longer-term holders are using the strength to take profit. That flow doesn't cancel out the bullish case, but it does mean the market is absorbing supply at the same time it's absorbing forced demand — a balance worth watching.

Political tailwinds add to the mix The rally wasn't purely a derivatives story. President Trump used a White House meeting with cryptocurrency executives on August 19 to urge Congress to pass the Digital Asset Market Clarity Act, adding a regulatory tailwind to the macro one. Renewed momentum on that legislation, which had stalled earlier in the year, gives traders another reason to stay constructive heading into September.

What comes next The more recent liquidation data already shows the squeeze losing some of its force — the latest 24-hour figures put short liquidations closer to $1 billion, down more than 60% from the initial burst. That's the natural progression: once the over-leveraged shorts are cleared out, the rally has to stand on its own, powered by spot demand rather than forced buying.

Market participants will be watching three things closely: whether ETF inflows can sustain their recent pace, whether Bitcoin can hold above its 200-day moving average near $69,000 as new support, and whether progress on the Clarity Act translates into further institutional interest. A squeeze of this size proves how thin liquidity had become on the short side — it doesn't yet prove a new bull cycle is underway.
