The latest joint analysis from Bybit and Block Scholes sheds light on critical trends shaping the cryptocurrency derivatives landscape as markets navigate post-holiday conditions in early 2025. This comprehensive report focuses on Bitcoin (BTC) and Ethereum (ETH) options dynamics, offering actionable insights into volatility patterns, open interest behavior, and market sentiment following key expiration events.
Year-End Options Expiry Sees Resilient Open Interest
Despite BTC and ETH perpetual contract open interest not yet recovering to early December 2024 peaks, both assets demonstrated remarkable resilience during year-end options expiries. The stability in open interest suggests that traders did not heavily rely on perpetual swaps to hedge delta exposure from expiring options—a factor that likely contributed to subdued volatility during this period.
Trading volume declined over the winter holiday season, aligning with a sharp drop in realized volatility to its lowest level since December. This seasonal lull is typical but remains significant for traders assessing positioning ahead of potential Q1 2025 momentum shifts.

BTC Options Curve Remains Steep at Parity
One of the most notable findings in the report is the persistent steepness of the BTC options implied volatility term structure. Longer-dated options continue to trade with implied volatility around 57%, while one-week at-the-money (ATM) options are priced approximately five percentage points lower.
Contrary to expectations of a volatility spike around expiry, realized volatility actually decreased, settling near the bottom of recent ranges. This divergence between implied and realized volatility highlights cautious market positioning.
Moreover, most expiring contracts were not rolled over, indicating limited leverage buildup in the options market. Put-call ratios remained balanced, reflecting neutral sentiment among traders. Compared to early December 2024, when speculative leverage was more pronounced, current conditions point to a more disciplined and risk-aware trading environment.
This structural calm suggests that while long-term uncertainty remains priced in, short-term traders are not anticipating explosive moves—making BTC’s price action during this phase relatively stable and range-bound.
ETH Options Expiry Fails to Trigger Volatility Surge
Ethereum experienced a large volume of options expirations at the end of December 2024, yet the market absorbed these events without significant disruption. Realized volatility, which spiked late in 2024, did not carry over into January 2025. Instead, spot price fluctuations have settled below levels implied by short-term options pricing.
A key divergence emerges when comparing ETH to BTC: while BTC maintains a steep volatility curve, ETH’s term structure briefly steepened before flattening again over the past week. This shift signals a different market psychology—one that may be preparing for sudden price movement.
Interestingly, despite the quiet post-expiry environment, bullish call options have gained strong traction in early 2025. Call dominance has surged, reflecting growing optimism among ETH traders about future price appreciation. This positive sentiment could serve as a catalyst if triggered by upcoming network upgrades or macroeconomic developments.

Market Implications and Strategic Takeaways
The data reveals two distinct narratives:
- BTC: A mature, stable derivatives market with controlled leverage and structured risk management. The steep long-end volatility curve suggests that traders remain alert to potential macro shocks or regulatory catalysts later in 2025.
- ETH: A market transitioning from consolidation to potential breakout. The flat volatility curve combined with rising call activity indicates suppressed volatility may be building pressure for a directional move—either up or down—depending on catalyst timing.
For active traders, these conditions present unique opportunities:
- BTC offers a reliable environment for volatility arbitrage and calendar spread strategies.
- ETH’s compressed volatility and growing bullish bias make it a prime candidate for directional bets ahead of potential news events.

Frequently Asked Questions
Q: What does a steep BTC volatility term structure indicate?
A: A steep term structure means longer-dated options are priced with higher implied volatility than shorter-dated ones. This typically reflects uncertainty about future macroeconomic conditions or anticipated events months ahead, such as ETF decisions or monetary policy shifts.
Q: Why didn’t ETH experience increased volatility after options expiry?
A: Large expiries don’t always trigger volatility. In this case, minimal hedging via perpetuals and balanced put/call ratios prevented cascading liquidations. Additionally, holiday-season thin liquidity may have muted immediate price reactions.
Q: How can traders use flat ETH volatility curves strategically?
A: Flat or inverted curves often precede breakout moves. Traders might consider long straddles or strangles to capitalize on expected volatility expansion, especially around catalyst-rich periods like protocol upgrades or economic announcements.
Q: What role does open interest play in predicting price movement?
A: Rising open interest alongside price increases suggests new money entering the market (bullish). Conversely, falling open interest during price drops may signal capitulation. Stable open interest post-expiry, as seen now, reflects market maturity and reduced speculative frenzy.
Q: Is low realized volatility bullish or bearish for crypto?
A: It depends on context. Low realized volatility after a sell-off suggests stabilization—a potential base formation. However, prolonged low volatility can also precede sharp breakouts in either direction, especially when implied volatility remains elevated.
Q: How reliable are options-based sentiment indicators?
A: Very reliable when combined with on-chain and spot market data. Metrics like put/call ratios, skew, and gamma exposure help identify overbought or oversold conditions and potential inflection points in price trends.
