Why Natural Gas Prices Dipped Just Before a Contract Expired
US natural gas futures fell ahead of the November contract's expiration, as a milder outlook for weather-driven demand weighed on the market, according to a Wall Street Journal report dated 1 October 2026.
A futures contract is an agreement to buy or sell something at a set price on a set future date. The contract in question is the Henry Hub benchmark, which is quoted in dollars per million British thermal units, or mmBtu. A British thermal unit is a measure of heat energy, so the price is for a fixed amount of gas.
Why should someone who never trades care? Henry Hub prices feed into what utilities pay for gas, and, with a lag, into the gas part of retail bills. That is why people well outside the trading floor watch the nearest contract closely. When forecasts call for less cold weather, expected demand drops, and the extra price that cold-weather worry adds to near-term contracts tends to shrink. That is the mechanism the Journal's report describes.
The most recent price in CME Group data comes from the evening of 26 October 2026. At 8:27 p.m. Central time, CME listed Henry Hub futures at 3.035, up 0.013 (+0.43%), on volume of 2,172 contracts. Volume is the number of contracts that changed hands.
CME's settlement page gives more detail for the two nearest months. November 2026 is listed at 2.787, 2.792, 2.620 and 2.626. December 2026 is listed at 3.152, 3.162, 3.026 and 3.047. December is higher than November in every column, by roughly 37 to 42 cents. When later months cost more than earlier ones, traders call it contango. Think of it like paying more for a holiday hotel room than for a quiet week in spring. Here, the market is pricing winter gas above milder-season gas.
Whether that premium turns out to be justified depends on temperatures that have not happened yet. The price curve shows what buyers and sellers agree on today. It is not a forecast, and nobody should treat it as one.
Positions offer a second angle. An NGI analysis published 25 August 2026 found that Henry Hub futures positions, meaning bets that traders hold open, had increased by the equivalent of 29,326 contracts in the latest reporting week. A build like that can magnify price moves when weather forecasts shift, in either direction.
Dates matter for anyone holding contracts into expiry. CME's options calendar lists the November 2026 option (ONX26) for 27 October 2026, and the December 2026 option (ONZ26) for 24 November 2026. The futures calendar carries a settlement entry dated 25 November 2026. CME also says Micro Henry Hub futures, a smaller-sized version, stop trading one business day before the matching Henry Hub contract expires. That means smaller accounts face an earlier deadline. For trades on the price gap between two months, called calendar spreads, CME says Natural Gas TAS spreads (NGT) can be built from any combination of the first 12 consecutive monthly contracts on NYMEX.
The broader context here is a market trying to price one question: how cold the coming winter turns out. A milder outlook pushes the nearest months' prices lower, yet the December premium suggests traders are not assuming a mild winter.
In my view, the more useful number to watch is the gap between November and December, not the headline price. The gap captures expectations for winter that a single price cannot. A single weather model run can move the headline price in a day. The gap has to be argued out over several runs, which makes it a steadier signal.
Prices in expiry week are often noisy. Trading is thin, and traders moving positions into the next month, a step called rolling, can distort the picture. Anyone reading the November move should separate those mechanical effects from real changes in the demand outlook. The Journal attributes the decline to the outlook, not to the roll itself.
