Previous report, watch levels and methodology

One-week surface context; the published headline retains its original evidence basis. Cutoffs 10 Sept, 16:29 UTC to 11 Sept, 16:29 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 ≤ 50.46 percent at . Current level 50.46; threshold is the current observed endpoint.
  • Full retrace: SOL 1W ATM IV ≥ 53.26 percent at . Current level 50.46; 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.

Chart notes

01 · Market read

The day across the three live Derivasys markets.

The major-coin complex separated at the one-week tenor, with a 4.40-volatility-point ATM IV change range between Ether and Solana.

Cross-sectional observations

One-week ATM IV level dispersion: Widening: absolute level gap 15.26 vol points; absolute gap change +0.99 vol points. Stored one-week tenor comparison at this cutoff across 3 assets.

Daily one-week ATM IV-change dispersion: The cross-asset spread is 4.40 vol points. Stored daily changes across 3 assets.

ETH stands apart: 1W ATM IV change is 4.25 vol points above the group median. Stored cross-section of 3 assets at this report cutoff.

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

Cross-sectional thesis

Where the complex is diverging.

One-week ATM IV level dispersion is widening, at 15.26 vol pts; daily one-week ATM IV changes span 4.40 vol pts across the complex.

ETH has the highest 1W IV-minus-7D-RV spread at +7.58 vol points; BTC has the lowest at +5.18 vol points. The range between these spreads is 2.40 vol points.

Aligned 24-hour spot correlations: BTC/ETH 0.82 (14 observations).

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 2.1–2.9 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.
