Ether's 2W RR25 rose 1.11 volatility points to -2.50 volatility points versus the October 11 cutoff at 16:30 UTC. The October 12 reading remained negative, so 25-delta puts still carried higher implied volatility than calls despite the shift toward calls.
Ether's 1W ATM implied volatility rose 1.99 volatility points to 42.68%, its largest standard-tenor increase between the October 10 and October 11 cutoffs at 16:30 UTC. The shorter tenor gained faster than 1M ATM IV, compressing the positive 1M-minus-1W slope. Ethereum ETF losses provide institutional context, without establishing a cause for the options move.
Ether's 1W RR25 increased 1.32 volatility points toward calls to -3.03 volatility points between the October 9 and October 10 snapshots at 17:02 UTC. The adjustment reduced the put-side implied-volatility premium without eliminating it, while the 2W skew barely changed over the same daily comparison.
Ether’s 1W ATM implied volatility fell 8.45 volatility points to 39.85% from the prior daily cutoff, marking the largest supported fixed-tenor adjustment. The October 8–9 snapshots show the contraction concentrated at shorter maturities, with a smaller 6M decline. Lower 1W butterfly convexity accompanied the move, while one-week skew remained tilted toward puts.
Ether 1W ATM implied volatility rose 8.90 volatility points to 48.73% since the prior daily cutoff, concentrating the adjustment in shorter maturities. The 2W options smile also shifted toward puts and greater wing convexity. Developing Ethereum infrastructure and corporate reports provide context, without an established link to the options repricing.
Ether's 1W RR25 fell 3.43 volatility points to -3.81 volatility points between the October 6 and October 7 snapshots at 16:30 UTC, according to Derivasys. The decline deepened an already negative call-minus-put volatility gap. Short-tenor implied volatility also increased, while reporting of continued Ether ETF outflows supplies institutional context without establishing a cause for the skew adjustment.
Ether 1W ATM IV recorded a change of -2.44 volatility points to 39.26% between the October 5 and October 6 snapshots at 17:08 UTC, the largest standard-tenor ATM IV decline. The compression extended through 2W and 1M. Ethereum’s Sepolia upgrade rehearsal, a resolved withdrawal incident and reported leveraged-fund listing approval supplied context, with no measured link to the options repricing.
Ether's 1W BF25 butterfly narrowed from 3.00 to 2.55 volatility points between the October 4 and October 5 snapshots at 16:29 UTC. The 0.45-point decline signals lower wing volatility relative to ATM, alongside falling front-end implied volatility and a shift in skew toward puts. Ethereum treasury purchases and staking queues provide news context, without establishing a cause for the options changes.
Ether's 2W BF25 butterfly increased 0.48 volatility points to 2.92% in the 24 hours ending 4 October at 16:30 UTC, widening average 25-delta wing implied volatility relative to ATM. The adjustment was concentrated in shorter maturities, while longer-dated butterfly measures declined. Near-term ATM volatility also increased. Al Jazeera's provisional Hormuz reporting provides economic context, without establishing a cause for the options changes.
Ether two-week BF25 fell 0.57 volatility points to 2.24% over the October 2–3 snapshot comparison, as front-end ATM implied volatility increased. The comparison describes the options surface at the report cutoff; it does not establish a news catalyst or a forecast for the underlying price.
Ether one-week ATM implied volatility fell 4.28 volatility points to 37.63% over the daily window ending October 2 at 16:30 UTC. The decline was concentrated at shorter maturities.
Ether’s options wings grew richer relative to ATM over the 24 hours to October 1 at 16:30 UTC, while one-week skew shifted further toward puts and the spot index barely moved.
Ether one-week call-minus-put RR25 fell 2.63 volatility points to -2.30% over the daily observation window ending September 30, reversing from a call-rich reading, according to Derivasys data. The relative shift toward puts accompanied a decline in volatility implied by options near the underlying price: Ether one-week ATM IV fell 3.19 volatility points to 42.90%. The combination establishes a skew reversal alongside lower central implied volatility, without establishing an absolute increase in put volatility.
Derivasys data show Ether one-week ATM IV fell 2.52 volatility points to 43.85% over the 24-hour observation window ending September 29. The broader front end also eased: Ether ATM IV across one-week, two-week and one-month options declined by an average 1.85 volatility points to 45.29%. ATM IV is the volatility implied by options near the underlying's current price. The repricing combined lower central volatility with reduced wing curvature, making the change broader than an isolated butterfly adjustment.
Derivasys data show Ether one-week RR25, the difference between call-side and put-side implied volatility, fell 1.96 volatility points to −2.02% over the daily observation window. That shift made the relative put side richer; it does not establish an absolute rise in put implied volatility. Ether one-week at-the-money implied volatility rose by 1.42 volatility points to 45.09%. The skew move was notable against comparable history, while the at-the-money move was routine.
Derivasys data show Ether one-week at-the-money implied volatility rose 2.01 volatility points to 43.69% over the observation window. That is volatility implied by options near Ether’s current price. The increase was concentrated at shorter maturities: Ether front-end ATM IV rose on average, while its long-dated ATM IV was broadly unchanged. Ether’s 24-hour spot-index return was positive 0.31%, providing a measured price comparison alongside the options move without explaining it.
Ether’s short-dated options priced more volatility between 25 September, 18:31 UTC and 26 September, 18:31 UTC, even as its spot index moved only slightly. Derivasys data show Ether one-week ATM IV rising 1.66 volatility points to 40.91%, while Ether’s 24-hour spot-index return was minus 0.21%. The one-week implied-volatility increase was routine against the available comparison history. Longer-dated ATM IV edged lower, leaving the repricing concentrated near the front of the curve. One-week implied volatility remained above the volatility realised over the latest day, though a matching seven-day realised-volatility comparison was unavailable.
Ether one-week ATM IV fell 6.11 volatility points to 38.75%, a large move at the 90th percentile of comparable recent observations. Derivasys data show front-end Ether ATM IV averaged 43.23%, down 3.78 volatility points, while long-dated Ether ATM IV averaged 53.88%, down 0.37 volatility points. The 24-hour Ether spot-index return was 0.19%; intraday realised-volatility comparisons were unavailable.
Ether options repriced lower across the front end, with two-week BF25 falling 0.45 volatility points to 2.70%. Derivasys data show one-week ATM IV fell 2.24 volatility points to 44.30% and front-end ATM IV averaged 46.50%, down 1.89 volatility points, placing the convexity decline within a broader reduction in near-term implied volatility.
In Ether options, three-month BF25 rose 0.31 volatility points to 3.27%, a large move at the 90th percentile of comparable recent observations in Derivasys data. BF25 measures the relative richness of wings versus at-the-money options. The rise contrasted with Ether one-week ATM IV, which fell 2.28 volatility points to 46.21%, while Ether front-end ATM IV across one week to one month averaged 48.02%, down 0.91 points. The Ether 26SEP26 forward price fell 3.38% to $2,670.31. One-minute realised-volatility comparisons were unavailable.
Ether three-month BF25 fell 0.39 volatility points to 2.96% during the observation window, an exceptional move at the 100th percentile of the available 30-day comparison set. The fall reduced the premium in options away from the centre of the distribution. Ether one-week ATM IV also declined 3.02 points to 48.25%, while the nearest eligible forward proxy, 25SEP26, rose 0.20% to $2,757.46 in Derivasys data.
Ether one-month RR25 rose 1.22 volatility points to 2.03% over the observation window, making call-side volatility relatively richer than put-side volatility. Derivasys data show the one-week ATM IV increase was more routine: one-week ATM IV rose 2.65 volatility points to 51.27%. The 24SEP26 Ether forward-proxy price rose 4.36% to $2,750.27, while long-end ATM IV changed only modestly.
Ether one-week RR25 fell 1.99 volatility points to 0.82% at the 16:30 UTC cutoff, sharply narrowing call-side volatility’s premium over put-side volatility without reversing it. Ether two-week ATM IV fell 0.56 points to 47.36%, and Ether’s 24-hour spot-index return was -1.03%. Derivasys data show Ether one-week ATM IV at 48.08%, 4.32 points below seven-day realised volatility of 52.40%.
Ether one-week BF25 rose 0.52 volatility points to 2.85%, the notable daily adjustment in the options surface. Ether one-week ATM IV rose 2.11 points to 48.21%, yet remained 2.89 points below Ether seven-day realised volatility at the cutoff. Ether’s 24-hour spot-index return was 2.04%, while long-dated ATM IV was unchanged.
