Bitcoin futures open interest has dropped to a five-month low of 587,584 BTC from 645,760 BTC on Aug. 14, according to Glassnode data cited by CoinDesk. The decline coincided with Bitcoin’s price rising from roughly $62,000 to $80,000 over the past weeks, with the move attributed more to short liquidations than to fresh leveraged long positions. Annualized funding rates for perpetual futures (contracts without an expiry date) have stayed below 10%, a level historically associated with limited overheating. A growing share of cash-margined futures (contracts backed by cash or stablecoin collateral) is also viewed as a sign of more conservative positioning and reduced risk of cascading liquidations. Together, lower open interest, stable funding and the shift toward cash-margined contracts point to a healthier market structure and support a cautiously optimistic view of the rally’s sustainability. Open interest is only one market indicator, however, and regulatory news or macroeconomic shifts could quickly change conditions in the highly volatile cryptocurrency market.
