Nat-gas prices retreated from a 1-week high on Wednesday and settled lower as a decline in European nat-gas prices to a 1-week low sparked long liquidation in US nat-gas futures. Nat-gas prices initially rose on Wednesday on the outlook for above-average US temperatures, which should boost nat-gas demand from electricity providers as air conditioning use is expected to increase. The Commodity Weather Group said Wednesday that above-average temperatures are expected across the South and Southeast through September 25.

Nat-gas prices also have support on expectations for a smaller-than-normal build in weekly storage levels. The consensus is that Thursday’s weekly EIA nat-gas inventories will increase by +48 bcf for the week ended September 11, well below the five-year average for the week of +74 bcf.

Monday’s rally in European gas prices to a 3.75-year high has provided carryover support to US gas prices. European nat-gas is soaring as sharply reduced supplies from the Middle East due to the closure of the Strait of Hormuz from the US-Iran war are keeping European nat-gas storage levels well below normal, a bullish factor ahead of winter, when demand typically surges.

In a bearish medium-term factor for nat-gas prices, the market is expecting a “Super El Niño” to bring warmer-than-normal temperatures to the Northern Hemisphere this fall and winter, reducing heating demand for nat-gas.

US (lower-48) dry gas production on Wednesday was 112.3 bcf/day (+4.0% y/y), according to BNEF. Lower-48 state gas demand on Wednesday was 76.3 bcf/day (+2.4% y/y), according to BNEF. Estimated LNG net flows to US LNG export terminals on Wednesday were 18.5 bcf/day (-4.7% w/w), according to BNEF.

As a positive factor for gas prices, the Edison Electric Institute reported Wednesday that US (lower-48) electricity output in the week ended September 12 rose +16.1% y/y to 94,427 GWh (gigawatt hours). Also, US electricity output in the 52 weeks ending September 12 rose +3.3% y/y to 4,405,549 GWh.

As a bearish factor, the US Energy Information Administration (EIA) on August 11 projected that US nat-gas storage levels will swell to 3,985 bcf at the end of October, the highest level in 10 years and 5% above the five-year average. Last Monday, the EIA raised its 2027 US dry natural gas production estimate to 116.0 bcf/day from 115.3 bcf/day projected in July.

Last Thursday's weekly EIA report was bearish for nat-gas prices, as it showed a +40 bcf increase in US nat-gas inventories for the week ended September 4, above expectations of +34 bcf, but below the 5-year weekly average of +52 bcf. As of September 4, nat-gas inventories were down -2.7% y/y and +4.8% above their 5-year seasonal average, signaling adequate nat-gas supplies. As of September 14, gas storage in Europe was 68% full, compared to the 5-year seasonal average of 85% full for this time of year.

Baker Hughes reported last Friday that the number of active US nat-gas drilling rigs in the week ended September 11 rose by +2 to 132 rigs, just below the 3-year high of 134 rigs set in February 2026.
