The cryptocurrency derivatives market continues to display nuanced shifts in sentiment, volatility, and positioning as we move through August 2024. Traders and institutional participants are closely monitoring key metrics such as implied volatility, funding rates, and options skew to assess directional bias and hedging demand. This analysis breaks down the latest developments across Bitcoin (BTC) and Ethereum (ETH) derivatives markets, offering actionable insights for informed decision-making.
Futures Implied Yield and Term Structure
BTC Annualised Yields
The BTC futures curve has experienced a slight steepening. This shift is primarily driven by declining yields in the front-end tenors, while longer-dated contracts have remained relatively stable. The flattening of near-term yields suggests reduced short-term speculative leverage, possibly reflecting caution amid macroeconomic uncertainty or profit-taking after recent price movements.

ETH Annualised Yields
ETH annualised yields continue to trade slightly below BTC across all maturities, maintaining a similarly steep term structure. This persistent yield discount may reflect comparatively lower demand for ETH leverage or differing risk perceptions between the two leading digital assets. However, the parallel shape of the curve indicates that market participants are pricing ETH's forward risk in line with BTC, adjusted for relative volatility and liquidity.
Perpetual Swap Funding Rates Signal Shifting Sentiment
BTC Funding Rate
BTC perpetual swap funding rates have turned positive again, signaling renewed trader appetite for long exposure. This shift typically occurs when bullish sentiment gains momentum—traders are willing to pay premiums to maintain leveraged long positions. A sustained positive funding environment could indicate growing confidence in upward price momentum, especially if supported by strong on-chain or macro fundamentals.
ETH Funding Rate
In contrast, ETH funding rates remain negative but are showing signs of recovery. The gradual normalization suggests that short-side pressure is easing, though bears still hold a marginal edge. This lag behind BTC may reflect slower capital rotation into altcoins or ongoing network-specific sentiment factors, such as anticipation around future protocol upgrades or staking dynamics.
Options Market Insights: Volatility and Skew
BTC SVI ATM Implied Volatility
Short-term implied volatility for BTC has declined, while longer-dated tenors have seen an increase. This inversion in the volatility curve often emerges during periods of stabilizing spot prices after volatility spikes, with traders pricing in higher uncertainty further out. The rise in long-term volatility premiums may reflect hedging against potential macro shocks or event-driven risks later in the year.
BTC 25-Delta Risk Reversal
The risk reversal profile remains call-skewed for longer-dated options, a trend that has persisted since the last major selloff. This indicates stronger demand for upside protection or speculative call buying, suggesting that institutional and sophisticated retail traders anticipate a bullish breakout over the medium to long term.

ETH SVI ATM Implied Volatility
Similar to BTC, ETH’s short-term implied volatility has decreased, while long-term levels remain stable. This pattern reinforces the idea that immediate price turbulence is subsiding, but structural uncertainty—possibly tied to regulatory developments or ecosystem growth—keeps long-dated options in demand.
ETH 25-Delta Risk Reversal
Short-term risk reversals for ETH have exhibited strong oscillations with an overall negative skew. This means put options are still more expensive than calls in the near term, reflecting residual bearish sentiment or hedging against downside risks. However, the volatility in skew magnitude suggests indecision in the market, with frequent shifts between fear and opportunistic buying.
Cross-Exchange Volatility and Skew Analysis
BTC & ETH: 1-Month SVI Calibration
Volatility metrics calibrated across major exchanges show consistent 1-month ATM implied volatility levels for both BTC and ETH. Minor discrepancies between platforms are within historical norms, indicating efficient price discovery and robust liquidity across venues. These stable readings suggest that arbitrage mechanisms are functioning effectively.
Put-Call Skew by Exchange (25-Delta SVI)
The 25-delta put-call skew remains slightly negative for BTC on most exchanges, though less so than in previous weeks. For ETH, the skew is more pronounced, with puts commanding higher premiums—especially on mid-tier platforms where liquidity is thinner. Traders should be mindful of exchange-specific imbalances when executing large options orders.
Advanced Volatility Surface Metrics
Market Composite Volatility Surface
The aggregated volatility surface across BTC and ETH reveals a flattening of the short-end volatility cone, with elevated wings in the long-dated options. This structure implies that while immediate crash fears have receded, tail risk hedging remains active for events expected in Q4 2024 or beyond—potentially including U.S. monetary policy shifts or regulatory milestones.
Listed Expiry Volatility Smiles
Volatility smiles for listed expiries show classic convexity, with pronounced wings at both ends of the strike spectrum. The left wing (low strikes) remains steeper than the right for ETH, indicating stronger demand for downside protection. BTC’s smile is more symmetric, reflecting balanced hedging behavior.
Cross-Exchange Volatility Smiles
When comparing volatility smiles across exchanges, we observe minor variations in skewness but consistent curvature. These differences can be exploited through inter-exchange arbitrage strategies by advanced traders with low-latency access and deep liquidity analysis tools.
Constant Maturity Volatility Smiles
The constant maturity model smooths out discrete expiry effects, revealing a structural rightward tilt in BTC’s long-term smile—another confirmation of call demand dominance. ETH shows less tilt, suggesting less consensus on long-term upside.
Frequently Asked Questions
Q: What does a steepening futures curve indicate in crypto markets?
A: A steepening curve—where front-end yields fall relative to longer-dated ones—often signals reduced short-term leverage and growing confidence in medium-term price stability or appreciation.
Q: Why are positive funding rates bullish for Bitcoin?
A: Positive funding rates mean longs pay shorts, indicating strong demand for leveraged long positions. Sustained positivity often precedes or accompanies upward price pressure.
Q: How can implied volatility help predict market moves?
A: Rising long-term volatility with falling short-term volatility suggests traders expect calm now but are hedging against future uncertainty—often ahead of major events.
Q: What does a call-skewed risk reversal mean?
A: A call skew means call options are more expensive than puts at the same delta, indicating stronger demand for upside exposure or bullish hedging.
Q: Why is ETH’s funding rate slower to recover than BTC’s?
A: ETH often lags BTC in sentiment cycles due to lower speculative leverage and different investor composition, including stakers and ecosystem developers who may not trade derivatives aggressively.
Q: How reliable is cross-exchange volatility data for trading decisions?
A: Highly reliable when aggregated properly. Consistent readings across exchanges confirm market efficiency; discrepancies may reveal arbitrage opportunities.
