Bybit and Block Scholesโ latest report reveals that the Bitcoin options market maintained stability in the face of year-end expirations, while Ethereum options are poised for brief volatility.
According to a report published by crypto exchange Bybit and analytics platform Block Scholes, open interest in Bitcoin (BTC) perpetual swaps remained stable throughout the year-end expirations. This stability came as a surprise, as options nearing their expiration date typically cause price swings.
The report suggests that traders are cautious but confident enough in their optionsโ stability that they did not overly rely on perpetual contracts to hedge the delta of expiring options. As a result, Bitcoin OI has stayed relatively stable, despite muted volatility and failing to recover to its higher December levels.
As previously reported by crypto.news, Bitcoin futures OI has dropped below the $60 billion threshold. The total BTC OI currently stands at around $56.6 billion, after plummeting at the start of January 2025. However, it hasnโt fallen as low as early November levels, when it dipped below $40 billion.
The report notes that the implied volatility term structure for BTC options remains steep, with implied volatility projected to stay at 57% over a one-week period for options trading five points lower.
Most of the expired open interest hasnโt been reinvested yet, resulting in a neutral call-put balance. This indicates that BTCโs options market shows limited leverage compared to its position at the beginning of December 2024.
Similarly, Ethereum (ETH) options remained stable through the end of December 2024. However, ETHโs spot price is showing lower volatility compared to its short-term implied volatility.
Over the past week, the implied volatility term structure for ETH options briefly plunged before flat-lining again. In contrast to BTCโs consistent downturn, ETHโs pattern suggests that its options market is preparing for potential short-term volatility in spot price movements.
Despite nearing expiration dates, ETH call options have gained momentum at the start of 2025. At the time of writing, Ethereum OI stands at $25.5 billion, returning to its mid-December levels.
