US natural gas futures, benchmarked at Henry Hub, traded in a narrow range near $2.80–$2.91 per MMBtu during the week of September 14, 2026, supported by above-normal cooling demand from persistent southern heat that produced below-average storage injections. The EIA reported a 44 Bcf build for the week ended September 11, narrower than seasonal norms and tightening the inventory surplus to roughly 3.7% above the five-year average. Strong LNG feedgas flows near 19 Bcf per day and lower domestic output provided additional lift, while record-high production levels limited broader gains. Global LNG prices rose on Middle East supply concerns, indirectly aiding US export economics. Traders are monitoring the next EIA storage release and late-September temperature forecasts for shifts in shoulder-season demand.
