Bitcoin’s Biggest Two-Year Pop Was a Classic Short Squeeze—Not Fresh Longs

Bitcoin didn’t rally because traders got brave—it rallied because shorts got trapped. A joint Glassnode–Bybit study shows that across five August sessions, BTC rose 24.6% while coin-denominated open interest fell 12.6%. That divergence is the tell: leverage didn’t expand with price; it unwound into the move.

Here’s the anatomy that matters. Roughly 64,000 BTC of open interest closed out during the burst, and short positions accounted for 89% of every liquidated dollar. Options echoed the squeeze dynamic. For 361 straight days, downside protection (puts) priced richer than upside (calls). One session snapped that streak as the market scrambled to reprice risk. Bybit’s volatility index traversed four times its typical daily range in a single day, and the futures term structure shifted in a way consistent with a shock rather than a secular pivot: the front of the curve moved sharply higher while longer-dated contracts barely budged.

The report’s scope is important. It’s a Glassnode–Bybit collaboration with data through the settled close of August 23, covering four crypto-native options venues and excluding CME—so the lens is the crypto-native derivatives stack, not every venue where BTC trades.

Why focus on this squeeze dynamic? Because it exposes how reflexive crypto markets remain when positioning is one-sided. After 361 days of put-rich skew, dealers and directional shorts were leaning the same way. A quick price impulse then forces systematic adjustments—shorts cover, dealers lift calls and cut puts, basis widens at the front—and the feedback loop does the rest. It feels like new demand; it’s often just old risk getting erased.

Traders looking for durability should watch three signposts: - Skew: Does call-bid skew persist, or do puts regain premium as fear resets? - Term structure: Does the front of the curve stay firm relative to the back, or does the curve relax as event risk fades? - Funding and OI: Do funding and coin-denominated open interest rebuild alongside price, signaling fresh risk-taking rather than forced exits?

Recent price action shows the pattern hasn’t disappeared. BTC pushed back above $80,000 this week after the Federal Reserve paired its first hike since 2023 with a dovish forecast. Spot prints hovered around $81,350 (+5.49% 24h), with a $81,864 high, $80,838 low, and reported volume near $887.0M. That jump triggered another squeeze: more than $230 million in Bitcoin shorts were liquidated, and over $445 million across the broader crypto market fell in a single session. CoinGlass tallied roughly $529 million in total 24-hour liquidations, again skewed toward shorts.

There’s a business and structural angle here that rarely gets discussed openly. Coin-margined leverage amplifies procyclical stress: when price rises, collateral quality improves for longs and deteriorates for shorts, accelerating liquidations. Venues benefit from activity but are also gatekeepers of liquidation engines and margin calibration. Ethically, that places a burden on platforms to design systems that minimize predatory cascades while keeping markets fair and continuous—especially when retail traders are enticed into high-gamma structures they don’t fully model.

If August’s repricing is going to stick, it should show up in stable call-bid skew and a persistently firm front end of the curve, with funding that doesn’t immediately fade. If puts reclaim premium and front-month strength softens, the market will have treated the move as an event it absorbed—powerful, yes, but not a regime change.

One squeeze can clear the lane. Sustained trends still need new capital, not just forced exits.
