Spot and volatility regime

ETH spot moved from about 2,445.6 yesterday to 2,611.5 today. Price has reclaimed 2,500 and moved back above 2,600, but it remains below the monthly upper ATR trigger at 2,659.1. On the monthly ATR frame, the current range uses about 38.6% of ATR, which still reads as mid-range repair rather than boundary breakthrough.

On the short horizon, both the 4h and 1d tails show price lifting cleanly out of the prior day’s lower range. Volume also expanded versus recent bars, which supports the view that this was a bona fide re-pricing move rather than an empty squeeze.

IV term structure, skew & DVOL regime

Implied vol surface

The surface still shows a clearly upward-sloping term structure. Near-term ATM IV is around 28.5%, while the far back end on 25JUN27 is in the 55%–57% area, so the curve remains steep from front to back. There is no sign of a flattened back end.

Skew remains rich on both sides. Put wings continue to trade well above ATM, with the short-dated 5P/10P/15P roughly in the 34.9% / 30.6% / 32.6% area. Call wings are also not cheap; the 5C wing is still around 55.8%. That combination says downside protection is still being paid for, while upside tail risk also retains premium.

DVOL index

DVOL is 49.92%, slightly below yesterday’s 50.13%. On a 1Y basis it remains in a depressed-to-low regime: roughly 9 IV Rank and 9 IV Percentile. On the 3M lens it is around Rank 30 and Percentile 27, which is higher, but still far from a stress extreme.

The key takeaway is that DVOL has not followed spot into a high-vol state. It has stabilized, not exploded, which keeps the move in the “spot-led repair” bucket.

Options chain structure

The chain’s center of gravity continues to migrate up into the 2,600–3,000 zone. Near-spot strikes and short-dated tenors are carrying the bulk of the action, especially 25SEP26, 30OCT26, and 25DEC26. The 2,600 strike is the clearest near-spot anchor, while 2,800 is the main upper extension zone and 3,000 remains a thick but somewhat unwound overhead layer.

The structure is not a one-way chase higher. There is still substantial put structure below spot around 2,500 and 2,300, and some of the 3,000 call complex gave back Open Interest (OI) today. That makes the upper area more layered than frictionless.

Net greeks and expiry × delta structure

Net greeks are split into a front-end absorption leg and a back-end supply leg.

By expiry:

• 25SEP26: turned into net delta / vega / gamma buying.
• 22SEP26: also showed net gamma and vega buying.
• 30OCT26, 25DEC26, 2OCT26, 26MAR27: predominantly net vega and gamma selling, with 25DEC26 and 30OCT26 the clearest sell-side expressions.

By strike:

• 2,800 and 2,700 stand out as buy gamma / buy vega zones.
• 2,600 is the most important concentration point and sits closest to spot.
• 3,000, 2,650, 2,580, and 2,550 skew more toward gamma / vega supply.

The read is straightforward: front-end hedging demand is still alive, while the back end is being used to sell vol into the rally.

Block and combo block trade flow (24h)

Block and combo prints in the 24 hours through the snapshot at 00:00 UTC on 19 Sep are net vega selling. The composition is still diverse — block-only is the largest bucket, with put spreads, call spreads, straddles, and calendars all appearing — but the net imprint is more defensive than yesterday.

Front-end structures still absorb some volatility, particularly in the 0–7d window, but the larger back-end tickets are leaning toward vega and gamma supply, mainly through 25DEC26 and 30OCT26 structures. Net delta is also less supportive than in the prior window, which reinforces the sense that real-money flow is more willing to fade the move after spot’s rally.

2. What Changed vs Prior Session(s)

• Spot: ETH rallied from roughly 2,445.6 to 2,611.5, a clear and forceful repair move back above 2,600.
• Vol: DVOL did not surge with spot; it edged lower, which argues for spot-led repricing rather than vol panic.
• Chain: Open Interest (OI) and activity continued to migrate upward. 2,600 is now the near-spot anchor, while 3,000 saw some give-back, so the shift is re-centering rather than pure chase.
• Greeks: 25SEP26 / 22SEP26 front-end buying is more visible; 25DEC26 / 30OCT26 back-end selling is heavier.
• Flow: Block/Combo sentiment flipped from net vega buying to net vega selling.

3. Multi-Day Context

Over the past week, the dominant theme has been “range digestion with a repair bias.” ETH spent most of the prior sessions rebuilding from the 2,400s, while the monthly upper trigger near 2,659 remained untouched.

Today’s move strengthens that weekly theme rather than replacing it:

• The chain has migrated higher, with 2,600 now the new near-spot center.
• 2,800 and 3,000 are more relevant now, but the monthly upper trigger has still not been tested.
• The broader structure is still range repair, just with a higher center of gravity and a more mature vol landscape.

So today reinforced the weekly theme of upward repair inside the monthly range, rather than marking a true trend breakout.

4. Key Levels and Risk Zones

• 2,611: current spot anchor.
• 2,600: the most important near-spot Gamma concentration and the primary pin risk.
• 2,659: monthly upper ATR trigger; first meaningful confirmation level for higher-range acceptance.
• 2,800: first upper Open Interest (OI) / activity / gamma extension zone.
• 3,000: second upper pressure zone; still thick structurally even after some Open Interest (OI) give-back.
• 2,500: nearest lower structural anchor, with substantial put support still in place.
• 2,275: monthly lower ATR trigger and the larger downside boundary.

5. Scenario Map for Next Session

Scenario 1: Continued push toward 2,659

If spot continues higher, the market will move into upper-trigger testing. Monitor:

• whether 2,600 continues to pin price,
• whether 2,800 extends further,
• whether 3,000 rebuilds call structure or continues to unwind.

Scenario 2: Range trade around 2,600

If spot consolidates around 2,600, intraday swings can widen because Gamma is concentrated there. Watch:

• whether 0DTE (expires same calendar day) / 1–7d activity stays elevated,
• whether put protection re-prices around 2,550 / 2,500,
• whether DVOL begins to lift alongside spot.

Scenario 3: Failed breakout and rollback

If the move fails and price slips back below 2,600, the new re-centered chain may partially unwind. Key checks:

• front-end Open Interest (OI) in 25SEP26,
• whether back-end vega supply in 30OCT26 / 25DEC26 persists,
• whether 2,500 regains status as the main spot-plus-put anchor.

6. Trader Focus

• The most important structural change today is that 2,600 has become the new near-spot anchor.
• DVOL did not track spot materially higher, so this remains a spot-led repair move rather than a vol-led expansion.
• Skew is still steep, and both put and call wings are expensive, which keeps outright directional chase from looking clean.
• Front-end buy gamma is still present, but back-end vega selling is heavier.
• The response around 2,659 will matter much more if spot keeps pressing higher.

Observation

Today did not change the dominant weekly theme: ETH is still repairing inside the monthly range, but the center of gravity has shifted materially higher. The market now has to decide whether 2,600 can hold and whether 2,659 can be tested next.
