Market context

ETH spot-index return unavailable; 1W ATM IV fell 5.20 volatility points to 42.10% over the daily window. RR25 moved toward puts (-2.06 points); BF25 wing premium decreased (-0.30 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 3 Sept, 16:48 UTC to 4 Sept, 16:48 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: ETH 1W ATM IV ≤ 42.10 percent at . Current level 42.10; threshold is the current observed endpoint.
  • Full retrace: ETH 1W ATM IV ≥ 47.30 percent at . Current level 42.10; 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 BTC, ETH and SOL complex became more dispersed: one-week ATM IV ranged from 32.01% for BTC to 48.96% for SOL, a 16.95-point spread.

Cross-sectional observations

One-week ATM IV level dispersion: Widening: absolute level gap 16.95 vol points; absolute gap change +2.54 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 2.70 vol points. Stored daily changes across 3 assets.

SOL stands apart: 1W ATM IV change is 2.54 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 16.95 vol pts; daily one-week ATM IV changes span 2.70 vol pts across the complex.

BTC has the highest 1W IV-minus-7D-RV spread at -4.90 vol points; SOL has the lowest at -9.55 vol points. The range between these spreads is 4.65 vol points.

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.
