The cryptocurrency derivatives market continues to evolve with shifting volatility patterns, changing sentiment, and growing institutional interest. As Bitcoin (BTC) and Ethereum (ETH) maintain their dominance in the digital asset space, derivatives data offers crucial insights into trader behavior, risk appetite, and forward-looking expectations. Drawing from recent analysis by leading institutional research providers, this report unpacks key trends in implied volatility, skew dynamics, and market structure as of mid-2025.
Understanding Implied Volatility in Crypto Derivatives
Implied volatility (IV) remains a cornerstone metric for assessing market risk and option pricing in crypto derivatives. Over recent weeks, both BTC and ETH have experienced elevated volatility levels, signaling increased uncertainty and speculative activity. However, the term structure—how volatility is priced across different expiration dates—has undergone a notable transformation.
For BTC, the 1-month at-the-money (ATM) implied volatility has seen a sharp rebound, climbing back above 50%. This surge reflects heightened demand for near-term protection or directional bets amid macroeconomic uncertainty and regulatory developments. More importantly, the term structure has flattened significantly, indicating that short-dated options are now commanding higher premiums than longer-dated ones—an inversion often associated with imminent market-moving events.

BTC Options: A Shift Toward Call Dominance
The BTC options market is displaying a clear preference for call options, as evidenced by the 25-delta risk reversal metric. This indicator, which compares the implied volatility of out-of-the-money (OTM) calls to puts, has turned positive—suggesting traders are increasingly positioning for upside moves.
While spot price movements have been choppy, the overall skew has shifted from put-heavy to call-heavy within a single week. This reversal underscores a growing bullish bias among institutional and sophisticated retail participants. Additionally, perpetual swap funding rates remain consistently positive, reinforcing demand for long positions in leveraged markets.
Despite these signals, the strength of bullish sentiment varies across instruments. While futures-implied yields point to strong optimism, the volatility surface does not yet reflect extreme euphoria—indicating that traders remain cautious even as they lean bullish.
ETH Options: Elevated Volatility Without Extreme Skew
In contrast to BTC, ETH’s implied volatility remains structurally higher across all tenors. The ATM IV for ETH options continues to trade at a premium relative to BTC, reflecting ongoing uncertainty around post-ETF adoption trends, staking dynamics, and network upgrades.
However, unlike BTC, ETH’s front-end volatility did not experience the same aggressive rally. This suggests that while traders anticipate movement, they are less convinced about the direction. The 25-delta risk reversal for ETH shows a slight bias toward OTM calls, but without the pronounced extremes seen in BTC markets.
This divergence may be partially attributed to the recent approval of spot ETH ETFs. While this milestone has boosted investor confidence, it has also led to profit-taking and rebalancing, tempering speculative enthusiasm in derivatives markets.
Market Composite Volatility Surface: What It Reveals
The composite volatility surface—a three-dimensional view of implied volatility across strike prices and maturities—provides deeper insight into market psychology. For BTC, the surface shows elevated curvature at short expiries, particularly on the call side. This “smile” steepening indicates demand for upside convexity, possibly driven by anticipated macro catalysts or technical breakouts.
For ETH, the smile remains broader but flatter, suggesting more balanced two-way risk pricing. Traders appear to be hedging both upside and downside scenarios equally, reflecting a wait-and-see approach despite the asset’s strong fundamentals.
These structural differences highlight a maturing derivatives ecosystem where BTC is increasingly viewed as a macro-risk proxy, while ETH retains its identity as a tech-driven, ecosystem-sensitive asset.

FAQ: Your Crypto Derivatives Questions Answered
Q: What does an inverted volatility term structure mean for traders?
A: An inverted term structure—where short-dated options are more expensive than longer-dated ones—typically signals near-term uncertainty or anticipation of major news. Traders may use this as a cue to adjust hedge ratios or prepare for increased price swings in the coming days.
Q: Why is BTC showing stronger bullish sentiment than ETH despite ETH’s ETF approval?
A: While ETH’s ETF approval was a significant milestone, BTC continues to dominate as a macro hedge and store of value. Institutional capital often flows into BTC first during risk-on environments, and its simpler narrative makes it more attractive during periods of economic volatility.
Q: How reliable are risk reversals as sentiment indicators?
A: Risk reversals are highly effective for gauging short-term trader positioning. A positive reading indicates call buying pressure, often linked to bullish sentiment. However, extreme readings can precede reversals, so they should be used alongside other metrics like open interest and funding rates.
Q: What role does funding rate play in derivatives trading?
A: Perpetual swap funding rates reflect the cost of maintaining long or short positions. Sustained positive rates indicate dominant long-side pressure, which can fuel momentum—but may also signal over-leverage and potential corrections.
Q: Are high implied volatility levels good or bad for options traders?
A: High IV increases option premiums, benefiting sellers who collect higher theta decay. Buyers, however, face steeper entry costs but gain leverage if large moves occur. Traders often shift strategies based on whether volatility is expected to rise or fall post-purchase.
