The August 2026 Henry Hub Natural Gas futures contract (NGQ26) expires today, July 29, 2026, per the CME Group official calendar. NGQ26 settled at $2.662 per MMBtu on July 28, the session prior to expiry. The prompt-month picture is steeply negative: spot natural gas traded at $2.69/MMBtu on July 29, down 0.23% on the day and off 17.72% over the trailing month, according to Trading Economics data.

The one-day decline is modest. The one-month erosion is not. A 17.72% drawdown over roughly 20 trading sessions, without a single clear catalyst identified in the available data, places the prompt strip firmly in bearish territory heading into the August contract roll.

Attention now shifts to NGU26, the September 2026 contract, which becomes the prompt month. CME's calendar page, last updated July 28, lists NGU26 with a last price of 2.697, off $0.004 or 0.15%, on thin volume of 1,225 contracts. Discrepancies across CME's own pages are worth noting for traders tracking the transition: the Futures Quotes page shows NGU26 at 2.763, while the Futures Overview page prints 2.701, and the Options Quotes page shows 2.697 for the same contract. The calendar page figure of 2.697 is the most recently timestamped and carries the additional detail of volume and intraday change.

The forward curve tells a different story from the spot weakness. CME's Futures Quotes page lists the following strip: NGQ26 (August) at 2.742, NGU26 (September) at 2.763, NGV26 (October) at 2.799, NGX26 (November) at 3.014, and NGZ26 (December) at 3.731. The spread between the expiring August contract and December sits at roughly $0.99/MMBtu, a 36% premium for winter delivery. That contango steepens sharply past October: the November-to-December jump alone is $0.717, or about 24%.

The structure is consistent with seasonal storage concerns, where winter heating demand introduces a risk premium that summer and shoulder-month contracts do not carry. Whether that premium is justified depends on storage levels, LNG feedgas demand, and weather patterns heading into Q4 — none of which are captured in the available data. What the curve does show is that the market is pricing material uncertainty into the back end of the year even as it discounts near-month gas.

On the options side, the August 2026 American-style option (ONQ26) expired on July 28, one day ahead of the futures expiry, as is standard for the contract. CME's Options Quotes page showed NGU26 with a last price of 2.697, aligned with the calendar page's futures print for the same contract.

The remaining 2026 contract expirations, per CME's calendar, proceed on a roughly monthly cadence: NGU26 (September) expires August 27, NGV26 (October) expires September 28, and NGX26 (November) expires October 28. The prior July 2026 contract (NGN26) expired June 26.

Looking at what this means for market participants: the roll from NGQ26 to NGU26 occurs with the front of the curve in backwardation relative to spot settle (August settled at $2.662, September quotes at 2.697 on the calendar page) but the broader strip in deepening contango. Traders rolling long prompt positions into September face a modest roll cost given that positive spread. The larger question is whether the 17.72% monthly decline has run its course or whether mild-weather demand destruction continues to weigh on prompt gas. The forward curve's winter premium suggests the market distinguishes between soft summer balances and tighter winter fundamentals — but that is a structural expectation, not a directional call on near-term price action.

For producers hedging winter exposure, the NGZ26 print at 3.731 offers a markedly different hedging level than the sub-$2.70 prompt gas available today. For consumers and utilities, the same curve implies meaningful cost escalation risk between shoulder months and peak winter. Both sides are looking at a curve that is not flat, and the steeper the winter premium grows relative to spot, the more incentive exists for storage injection now — assuming the economics of injection hold against the prevailing spot price.
