Solana leads as call skew steepens
Solana delivered the strongest spot move of the three major-coin reports, rising 3.02 per cent over the 24-hour window. One-week implied volatility climbed 2.56 points to 72.36 per cent and two-week risk reversal swung 4.02 points towards calls. The surface stayed inverted and seven-day realised volatility remained higher than one-week implied volatility. No sufficiently relevant Solana headline was found, so the report leaves the repricing unattributed.

What changed across the SOL volatility surface.
Implied versus realised
At the 14:11 UTC cutoff, 1W ATM IV was 72.36%, 4.10 volatility points below seven-day realised volatility of 76.46%; 24-hour realised volatility was 41.65% and 30-day realised volatility was 61.57%.
Front end
Front-end ATM IV increased, averaging +0.86 volatility points to 69.79% across 1W, 2W and 1M.
Long end
Long-dated ATM IV increased, averaging +0.43 volatility points to 59.52% across 6M and 1Y.
Skew
RR25 moved towards calls, averaging +1.44 volatility points to 4.07 volatility points across the six available headline tenors.
Convexity
BF25 decreased, averaging -0.71 volatility points to 4.99 volatility points across the six available headline tenors.
Largest standard-tenor move
The largest standard-tenor ATM IV move was +2.56 volatility points at 1W, to 72.36%.
Universe roll: added 1SEP26; removed 30AUG26. Comparisons use common expiries only.
RR25 moved towards calls, averaging +1.44 volatility points to 4.07 volatility points across the six available headline tenors. Negative RR25 denotes a richer 25-delta put wing under the call-minus-put convention.
BF25 decreased, averaging -0.71 volatility points to 4.99 volatility points across the six available headline tenors. BF25 measures the average 25-delta wing premium over ATM IV.
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.

Completed-session cross-asset context
Crypto volatility against US equity risk.
SOL 30-day implied volatility was 4.7 times VIX, while its 30-session return correlation with SPX was low at 0.18.
Implied-volatility premium
SOL 30-day ATM IV was 67.60%, against VIX at 14.43: a 53.17-point spread and 4.68× ratio.
Realised-volatility regime
SOL 20-calendar-day realised volatility was 69.20%, versus SPX 20-session realised volatility of 10.58%. The spread ranked at percentile rank 45.6% of 217 prior observations.
Equity co-movement
Return correlation with SPX was 0.183 over 30 aligned sessions and 0.433 over 60 sessions. VIX9D, VIX and VIX3M closed at 11.22, 14.43 and 17.48.
As of 28 Aug 2026, 20:00 UTC. Implied volatility and completed-session realised volatility use their respective observation windows shown above.
Evidence and methodology
Crypto realised volatility uses 20 calendar days and sqrt(365); SPX uses 20 US sessions and sqrt(252). The two clocks are shown explicitly and the figures are contextual, not causal attribution.

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.
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.
