Solana options compress as one-week volatility falls while calls remain richer
Solana one-week ATM IV fell 4.33 volatility points to 56.08%, the largest absolute one-week ATM IV move among the major coins in Derivasys data. Front-end ATM IV across one week to one month averaged 56.16%, down 2.51 points. Solana one-week RR25 fell 1.66 volatility points to 3.55%, but remained positive, meaning call-side volatility was still richer than put-side volatility. The nearest forward proxy, 2OCT26, fell 3.51% to $114.36. One-minute realised-volatility comparisons were unavailable, and long-dated fixed-tenor observations were unavailable.

02 · Options market read
What the volatility surface did.
4 of 6 headline tenors were comparable at both endpoints. The largest ATM IV move was 1W at -4.33 volatility points, to 56.08%.
The intraday RV comparison is unavailable because the one-minute index-return series failed its completeness check. This affects the 24-hour, seven-day and 30-day comparison block.

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.

Current surface characteristics
Where normalized model Greek intensity is highest.
These are comparable Black-forward Greeks for a one-SOL ATM-forward call at each listed expiry—not portfolio exposure, open interest or a prediction of dealer positioning.
SOL 30-day implied volatility was 4.0 times VIX, while its 30-session return correlation with SPX was mixed at 0.40.
Implied-volatility premium
SOL 30-day ATM IV was 57.26%, against VIX at 14.21: a 43.05-point spread and 4.03× ratio.
Daily-close realised-volatility regime
SOL 20-calendar-day realised volatility was 74.02%, versus SPX 20-session realised volatility of 10.59%. The spread ranked at 48.9 percentile of 233 prior observations.
This separate RV estimate uses 20 daily close-to-close log returns, sampled at 16:00 New York time, ending at the completed-session timestamp shown below. It requires a valid close for each day, rather than every intervening minute. Crypto RV is annualised with √365; SPX uses 20 trading-session returns and √252. It does not replace the intraday IV–RV comparison.
Equity co-movement
Return correlation with SPX was 0.402 over 30 aligned sessions and 0.324 over 60 sessions. VIX9D, VIX and VIX3M closed at 12.13, 14.21 and 17.61.

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.
