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.

Near-settlement moves, shown with context.

Contracts with fewer than 2 full days to expiry remain in the tables but are excluded from headline rankings. Settlement proximity, time decay, changing liquidity and fewer quotes can exaggerate their changes.

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.

SOL 30-day implied volatility was 2.9 times VIX, while its 30-session return correlation with SPX was mixed at 0.60.

Implied-volatility premium

SOL 30-day ATM IV was 55.05%, against VIX at 19.03: a 36.02-point spread and 2.89× ratio.

Daily-close realised-volatility regime

SOL reported crypto realised volatility was 48.15%, versus SPX reported realised volatility of 9.98%. The spread ranked at percentile rank 32.2% of 255 prior observations.

Equity co-movement

Return correlation with SPX was 0.596 over 30 aligned sessions and 0.418 over 60 sessions. VIX9D, VIX and VIX3M closed at 18.86, 19.03 and 20.12.

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 22 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.

Generated from measured Derivasys surface data.

Current snapshot
23 Oct 2026, 16:31 UTC
Comparison snapshot
22 Oct 2026, 16:31 UTC
Source
Derivasys proprietary historical SVI surface and canonical SOL index databases
Realised volatility
Annualised root-mean-square of one-minute canonical SOL-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-SOL ATM-forward call, zero rate, fitted SVI IV
Catalyst policy
Only sufficiently relevant, reliably sourced events are shown; otherwise no catalyst is assigned.
