Spot and volatility regime

Both daily and 4H closes stayed above 2,600, which keeps the short-term recovery intact. On the monthly ATR framework, ETH is still trading within the 2,275–2,659 band; spot is now right under the upper trigger, so the top of the range is becoming a real test, but not yet a confirmed breakout.

Across the recent one-week repair, ETH has steadily reclaimed the 2,600 area and pushed into the upper-edge zone. The market structure is still constructive, but not yet strong enough to reclassify the higher-timeframe regime as trend continuation.

IV term structure, skew & DVOL regime

Implied vol surface

The term structure still slopes higher in the front end versus the back end, but the main story today is the sharp lift in front-end ATM IV to about 39.7%, a very meaningful recovery from yesterday’s low base. Short-dated IV is being repriced across the curve rather than isolated to one Tenor bucket rollup.

Skew remains put-rich versus ATM, especially in the 5P/10P/15P area, which tells us downside protection is still expensive. The move is broader than a single wing bid; short and intermediate tenors both moved up, which looks like a front-end curve re-marking rather than a one-strike vol spike.

DVOL index

DVOL rose to 51.48, extending yesterday’s move higher and continuing to recover faster than spot. On the 1Y lookback, rank/percentile are still in the lower part of the historical range, though they are climbing; on the 3M lookback, the index is back near neutral. This is a recovery from depressed vol, not an extreme vol regime.

Options chain structure

The options chain remains concentrated in the front end, especially 25SEP26 as the largest Open Interest (OI) anchor, but the day’s incremental volume and Open Interest (OI) are spread across 0DTE (expires same calendar day), 1–7D, and some 8–30D maturities. That says the market is still running near-dated re-pricing rather than pushing all risk into the back end.

By strike, 2,600 is the clearest near-spot hub, with both call and put inventory thick around it. Call Open Interest (OI) remains stacked at 2,800 and 3,000, showing that upside tail participation is still intact. Lower strikes around 2,500/2,400/2,300 retain active put interest, so the chain continues to carry both upside chase and downside defense.

Net greeks and expiry × delta structure

Over the last 24 hours, net greeks show a shift toward long gamma and long vega in the front and intermediate tenors. 9OCT26, 25SEP26, 23SEP26, 24SEP26 and 22SEP26 all printed meaningful vega buying and gamma buying, while 25DEC26, 26MAR27 and 30OCT26 leaned toward vega selling and gamma selling.

At the strike level, the main accumulation zones are 2,800, 2,600, 2,700, 2,650 and 2,580, which confirms that risk is migrating closer to spot rather than abandoning the upper strikes. Meanwhile, 3,000, 4,000 and parts of the far upper tail still show notable seller pressure, so the far end is not uniformly repricing higher.

Overall, this is best read as near-dated vol buying with a mixed back end, not a uniform vol bid across the curve.

Block and combo block trade flow (24h)

Block and combo prints in the 24 hours through the report snapshot at 00:00 UTC on Sep 21 (rolling window, not the calendar report day) were dominated by put spreads, call spreads and iron condors, so the structure remains spread-heavy rather than naked directional. Even so, the more active near-dated and some mid-dated prints show higher vega/gamma buying, especially across 25SEP26, 21SEP26, 24SEP26 and 30OCT26-linked trades.

Net vega in Block/Combo compressed materially from a more one-sided vol-selling posture into something closer to neutral, though still slightly negative. That points to a meaningful easing of sell pressure and a more balanced internal mix. It aligns with the front-end lift in the IV surface, but it does not yet prove a full market-wide pivot into vol chasing.

2. What Changed vs Prior Session(s)

The clearest change is that spot pushed higher again and is now just under the monthly upper trigger, while front-end IV and near-dated gamma/vega buying rose in sync. In other words, price moved into the upper edge of the range and vol responded first.

Compared with yesterday, the front of the curve lifted more clearly, while downside put wings stayed rich. That means the market did not relax downside protection just because spot rallied. The back end, however, did not shift uniformly higher; it still carries more mixed vega/gamma selling traces.

On the flow side, yesterday’s more heavily sold-vol tone weakened. Block/Combo also moved from a more one-sided structure into a more mixed one, which is consistent with the 24h net-greek shift toward front-end vol buying.

3. Multi-Day Context

The weekly theme has not changed: ETH has been repairing back toward the top of its monthly range, first recovering the 2,500 area, then 2,600, and now pressing toward the 2,659 upper trigger. Today’s tape says the repair path is still intact and, if anything, has accelerated toward the range ceiling.

What has remained consistent over the past few days is that IV tends to respond before spot when price reaches a higher level. Today’s front-end IV lift, DVOL recovery and stronger near-dated gamma buying all show the market is paying for the possibility of an upper-edge break.

So today reinforces, rather than weakens, the dominant weekly theme: range repair plus upper-edge probing. The difference now is that near-term risk is increasingly concentrated into the front-end curve and the 2,600–2,659 band.

4. Key Levels and Risk Zones

• 2,659: monthly upper ATR trigger; the key breakout/failure line for the next test.
• 2,600: the most important near-spot anchor and structural pivot. As long as it holds, the repair remains viable.
• 2,500: secondary pivot. A loss here would make front-end vol and downside wings more dangerous.
• 2,275: monthly lower trigger; still far below, but a loss would materially damage the higher-timeframe structure.

From the options structure, 2,600 remains the densest Open Interest (OI) and flow center, so short-term pinning risk is still alive. Above that, 2,800/3,000 remain the main upside observation zone; below that, 2,500/2,400/2,300 are the key downside defense and acceleration zones.

5. Scenario Map for Next Session

Scenario 1: Continued grind higher toward 2,659

If spot holds above 2,600 and keeps grinding higher, front-end IV can stay firm and near-dated gamma/vega buying may remain sticky. In that case, the 2,600–2,659 zone becomes the main upper-edge digestion area.

Scenario 2: Rejection under 2,659 and rotation back toward 2,600

If price stalls again under 2,659, the front-end IV lift is more likely to behave as sticky high vol rather than a clean expansion. Then 2,600 reasserts itself as the magnet, and near-term structures are more likely to stay range-oriented.

Scenario 3: Loss of 2,600

If 2,600 fails, the rich downside wings and concentrated near-dated gamma could amplify the downside move, with a retest of 2,500 becoming more likely. At that point, front-end vol could remain bid even as spot softens.

What to monitor next session

• Whether spot continues to hold above 2,600 or slips back below it.
• Whether 2,659 gets tested cleanly or becomes another cap.
• Whether 25SEP26 / 0DTE (expires same calendar day) / 1–7D flow stays skewed toward gamma and vega buying.
• Whether 2,600 Open Interest (OI) keeps building or starts being actively unwound.
• Whether front-end IV remains elevated or fades quickly if spot stalls.

6. Trader Focus

1. Today is an upper-edge test, not a confirmed breakout.
2. 2,600 remains the most important structural center.
3. Front-end IV, DVOL and near-dated gamma/vega are all repricing higher together.
4. The back end remains mixed, so this is not yet a uniform long-vol regime.
5. For the next one to two sessions, the key is whether the 2,600–2,659 band continues to compress price while front-end vol stays bid.

Interpretation

Today pushes ETH further into the upper part of its monthly range, but not through the line. Spot is stronger, and volatility is leading the move, which tells us the market is not just reading direction — it is paying up for near-term risk.

More importantly, today’s move was not simply “spot up, vol up.” Spot, the implied vol surface and large-trade flow all improved together at the front end: IV lifted, gamma/vega buying increased, and risk was pushed toward shorter tenors. For an options desk, that means the next couple of sessions are about whether the upper edge can actually open up, and whether front-end vol can remain sticky.

Observations

• 2,600: the key pivot and magnet.
• 2,659: monthly upper trigger; the breakout/failure line.
• 25SEP26: the largest Open Interest (OI) anchor and front-end pricing hub.
• 0DTE (expires same calendar day) / 1–7D: the main battlefield for near-term vol repricing.
• DVOL at 51.48: still recovering, so the vol repair is not done yet.
