Major-coin options diverge as solana volatility drops fastest

Major-coin options saw a pronounced short-dated divergence: SOL one-week ATM IV fell 7.61 volatility points, versus a 1.17-point fall for ETH, creating a 6.44-point dispersion. SOL nonetheless retained the highest one-week ATM IV at 53.34%, 22.31 volatility points above BTC’s 31.03%. Ether carried the richest relative put-side volatility, with 1W RR25 at -2.00 volatility points.

Market context

SOL spot-index return unavailable; 1W ATM IV fell 7.61 volatility points to 53.34% over the daily window. RR25 moved toward puts (-1.41 points); BF25 wing premium decreased (-1.47 points); 3/3 assets had lower 1W ATM IV; partial native coverage (9/12 measurements).

Previous report, watch levels and methodology

One-week surface context; the published headline retains its original evidence basis. Cutoffs 1 Sept, 16:30 UTC to 2 Sept, 16:30 UTC.

Measured change since prior report

Prior comparison unavailable: the exact adjacent published edition could not be verified.

A structured watchlist was not recorded or could not be verified in the prior edition; prior-watch outcomes remain unavailable.

Next daily cutoff: measurable checks

These checks are reconstructed from this edition’s stored endpoints; they were not recorded in the original report.

  • Hold the observed level: SOL 1W ATM IV ≤ 53.34 percent at . Current level 53.34; threshold is the current observed endpoint.
  • Full retrace: SOL 1W ATM IV ≥ 60.95 percent at . Current level 53.34; threshold is the previous observed endpoint.
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. Derived from verified legacy artifact endpoints.

01 · Market read

The day across the three live Derivasys markets.

The major-coin story was dispersion rather than a uniform repricing: SOL’s one-week ATM IV fell substantially faster than the BTC and ETH equivalents.

This is a comparison, not a pooled surface: each asset keeps its own forwards, expiries, SVI fit and realised-volatility history.

Completed-session cross-asset context

Crypto volatility against VIX and SPX.

The benchmark comparison is separately timestamped to the latest completed US session; it does not replace the intraday crypto surface cutoffs above.

BTC and ETH and SOL 30-day implied volatility remained 2.2–3.4 times VIX, while short-window equity correlations remained low.

A derived publication with no duplicated market data.

The report is assembled at request time from the immutable BTC, ETH and SOL daily-report artifacts for the same UTC report date. It is omitted unless all three exist. Cross-asset averages are descriptive and equal-weighted; no attempt is made to combine distinct volatility surfaces into a single fit.
