Bitcoin has surged from roughly $62,000 to $80,000 over the past week, marking its second-strongest weekly performance in five years. Such a rapid move would typically encourage traders to increase leverage through futures and other derivatives.
This time, the rally looks different. Instead of being powered mainly by fresh long positions, the advance appears to have been driven largely by short sellers exiting bearish trades.
Futures open interest (OI) reinforces that view. Bitcoin-denominated OI has fallen to around 587,584 BTC, the lowest level in almost five months, compared with 645,760 BTC on Aug. 14, according to Glassnode. Measuring OI in BTC provides a more accurate view of market positioning because it removes the effect of Bitcoin’s rising dollar price.
The key takeaway is that Bitcoin has climbed even as futures exposure has declined. Traders holding short positions either bought back their contracts to close them or were forcibly liquidated after failing to meet margin requirements.
The resulting short squeeze wiped out billions of dollars in bearish positions and helped drive Bitcoin above the $80,000 mark.
Perpetual futures funding rates provide another indication that leverage remains contained. Annualized funding has stayed below 10%, suggesting only moderate demand for leveraged longs. If traders were aggressively chasing the rally with new long positions, funding rates would likely be much higher.
Lower Leverage Could Support the Rally
The decline in derivatives activity may be a positive development because fewer leveraged positions can reduce the risk of sharp reversals and potentially make the rally more durable.
The trend is particularly notable in crypto-margined futures. Glassnode data shows open interest in contracts backed by BTC or other cryptocurrencies has fallen to an all-time low of roughly 52,000 BTC, representing just 11% of total futures activity.
A greater reliance on cash collateral can make the market more resilient during downturns. Cash-backed positions retain their nominal value even when Bitcoin falls, while crypto collateral loses value alongside the market. That can create a feedback loop in which falling prices weaken collateral, trigger liquidations and push prices even lower.
The continued shift toward cash-margined futures may therefore be contributing to Bitcoin’s lower volatility compared with previous market cycles.
