Measurement basis and receipt

These are observed-level conditions for the next aligned cutoff, with no forecast or trade action. Spot uses exact index endpoints where available; ATM IV is quoted in percent and its change, RR25 and BF25 in volatility points. Stored editorial receipt independently reconstructed against native endpoints.

Each cell is the fitted IV change in volatility points. Rows are listed expiries; columns run from the put wing through ATM to the call wing.

Completed-session cross-asset context

Crypto volatility against US equity risk.

ETH 30-day implied volatility was 2.7 times VIX, while its 30-session return correlation with SPX was mixed at 0.67.

Implied-volatility premium

ETH 30-day ATM IV was 52.68%, against VIX at 19.42: a 33.26-point spread and 2.71× ratio.

Daily-close realised-volatility regime

ETH reported crypto realised volatility was 39.80%, versus SPX reported realised volatility of 11.78%. The spread ranked at percentile rank 17.8% of 264 prior observations.

Equity co-movement

Return correlation with SPX was 0.674 over 30 aligned sessions and 0.385 over 60 sessions. VIX9D, VIX and VIX3M closed at 19.25, 19.42 and 20.78.

RV comparison basis unverified: this edition does not record the recognised provider methodology for both horizons and annualisation conventions. The displayed spread rank does not establish matched-horizon comparability.

As of 30 Oct 2026, 20:00 UTC. Implied volatility and completed-session realised volatility use their respective observation windows shown above.

Evidence and methodology

market-context-v1

RV observation windows and sampling

The 24-hour, seven-day and 30-day RV windows are assessed independently using observed one-minute index returns, annualised on a 365-day basis. Recorded minimums: at least 99.5% coverage over 24 hours, 99.5% coverage over seven days, 99.5% coverage over 30 days, with no gap longer than 60 minutes. Returns spanning gaps are excluded, not interpolated; unavailable windows remain unreported. The exact 24-hour spot return requires prices at both endpoints.

Where normalized model Greek intensity is highest.

These are comparable Black-forward Greeks for a one-ETH ATM-forward call at each listed expiry—not portfolio exposure, open interest or a prediction of dealer positioning.

Thresholds are asset-specific policies recorded in this edition. Each window is assessed independently; returns spanning gaps are excluded. Partial estimates may miss volatility during gaps.

Generated from measured Derivasys surface data.

Current snapshot
31 Oct 2026, 17:31 UTC
Comparison snapshot
30 Oct 2026, 17:31 UTC
Source
Derivasys proprietary historical SVI surface and canonical ETH index databases
Realised volatility
Annualised root-mean-square of one-minute canonical ETH-USD index log returns using a 365-day basis; all windows end at the current snapshot.
Comparison window
Nearest successful surface snapshots approximately 24 hours apart
RR convention
25-delta call IV minus 25-delta put IV
BF convention
Average 25-delta wing IV minus ATM forward IV
Fixed tenors
Fixed-tenor measures are published only when listed expiries bracket the target at both comparison snapshots. Targets outside either observable range are suppressed, not extrapolated; headline rankings use only supported tenors.
Smile reconstruction
Listed-expiry smiles are reconstructed from stored SVI total-variance parameters on a fixed log-moneyness grid.
Ultra-short expiries
Expiries with fewer than 2 full days remaining stay in detailed tables but are excluded from headline rankings. Settlement proximity, time decay, changing liquidity and fewer quotes can exaggerate their changes.
Greek normalization
Black forward Greeks for a normalized one-ETH ATM-forward call, zero rate, fitted SVI IV
Catalyst policy
Only sufficiently relevant, reliably sourced events are shown; otherwise no catalyst is assigned.
