Solana options: 1W RR25 skew flips from calls to puts

Solana's 1W RR25 fell 5.66 volatility points from +0.95 to -4.71 volatility points between the October 15 and October 16 cutoffs, crossing from a call-side to a put-side volatility premium. The absolute daily change in 1W RR25 ranked at the 100th percentile among 22 matching observations from September 15 to October 15, 2026. The negative reading means put-side implied volatility exceeded call-side implied volatility; it does not establish that put implied volatility itself rose.

In constituent news, The Defiant reported that Solana's Shanghai event had been postponed, citing a surge in registrations as the explanation. The reporting provides organizational context, but the available evidence establishes no clear link between the postponement and the measured options-skew rotation.

SOL reported crypto realised volatility was 41.67%, versus SPX reported realised volatility of 9.61%. The spread ranked at percentile rank 18.8% of 250 prior observations.

Equity co-movement

Return correlation with SPX was 0.581 over 30 aligned sessions and 0.392 over 60 sessions. VIX9D, VIX and VIX3M closed at 13.97, 16.46 and 18.49.

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.

Original report summary

Solana's 1W RR25 fell 5.66 volatility points from +0.95 to -4.71 between the October 15 and October 16 cutoffs, shifting the call-minus-put volatility balance toward puts. Derivasys data also showed 1W ATM implied volatility falling 3.86 points to 52.19%, while butterfly curvature increased. The skew reversal therefore accompanied a lower overall implied-volatility level.

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.

13 · Methodology and provenance

Generated from measured Derivasys surface data.

Current snapshot: 16 Oct 2026, 16:31 UTC
Comparison snapshot: 15 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.
