October Nymex natural gas (NGV26) on Wednesday closed up +0.052 (+1.79%).
Nat-gas prices settled higher on Wednesday as hotter US weather is expected to boost nat-gas demand from electricity providers as air-conditioning use increases. According to forecaster Vaisala, forecasts trended hotter across the Midwest and East for September 7-11 and shifted warmer in the Midwest for September 12-16.
Expectations for a smaller-than-average seasonal build in US nat-gas storage also lifted prices on Wednesday. The consensus is that Thursday’s weekly EIA report will show nat-gas inventories increased by +32 bcf for the week ended August 28, below the five-year average of +37 bcf.
Nat-gas prices also had carryover support from a rally in European nat-gas prices. Fears that the closure of the Strait of Hormuz will be prolonged due to escalation of the US-Iran war pushed European nat-gas prices to a 3.75-year high on Wednesday. Europe receives about 10% of its nat-gas supplies through the strait from Qatar.
US (lower-48) dry gas production on Wednesday was 113.2 bcf/day (+3.4% y/y), according to BNEF. Lower-48 state gas demand on Wednesday was 79.5 bcf/day (+7.6% y/y), according to BNEF. Estimated LNG net flows to US LNG export terminals on Wednesday were 18.8 bcf/day (unchanged 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 August 29 rose +12.56% y/y to 96,357 GWh (gigawatt hours). Also, US electricity output in the 52 weeks ending August 29 rose +2.63% y/y to 4,375,966 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. On 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.
A bearish medium-term factor for nat-gas prices is speculation that a powerful El Niño weather system will bring warmer-than-normal temperatures to the Northern Hemisphere this fall and winter, reducing nat-gas heating demand.
Last Thursday's weekly EIA report supported nat-gas prices, showing a +15 bcf increase in US nat-gas inventories for the week ended August 21, right on expectations but below the 5-year weekly average of +33 bcf. As of August 21, nat-gas inventories were down -1.0% y/y and +5.5% above their 5-year seasonal average, signaling adequate nat-gas supplies. As of August 30, gas storage in Europe was 65% full, compared to the 5-year seasonal average of 82% 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 August 28 rose by +5 to a 5-month high of 132 rigs, just below the 3-year high of 134 rigs set in February 2026.
