European Gas Retrenchment Triggers US Futures Liquidation

US natural gas futures concluded the session with a 0.96% decline, retreating from a one-week high to settle lower. The price drop was driven by a synchronized retreat in European gas prices, which hit a one-week low and prompted significant long liquidation in US contracts. This movement reversed earlier gains seen during the day, which had been supported by forecasts for above-average temperatures in the southern and southeastern United States through September 25. These warmer conditions were expected to increase air conditioning usage, thereby boosting electricity generation demand for natural gas.

Market participants also found support in inventory expectations, with consensus estimates indicating a weekly build of 48 billion cubic feet (bcf) for the period ended September 11. This figure is substantially below the five-year average of 74 bcf, suggesting a tighter supply position than typical for this time of year. However, this bullish signal was overshadowed by the medium-term outlook, where market sentiment turned bearish on the prospect of a "Super El Niño" event. This weather pattern is expected to deliver warmer-than-normal temperatures to the Northern Hemisphere this fall and winter, which would structurally reduce heating demand for natural gas.

European Supply Shocks Drive Price Volatility

The volatility in US markets was closely tied to European dynamics, where gas prices had previously rallied to a 3.75-year high on Monday. This surge was fueled by sharply reduced supplies from the Middle East, a consequence of the Strait of Hormuz closure during the US-Iran conflict. These supply constraints have left European storage levels well below normal, creating a bullish environment ahead of winter. The subsequent retreat in European prices removed this carryover support, directly impacting US futures pricing and highlighting the interconnectedness of global gas markets.

According to GN auto stocks/utilities: gas storage data, US lower-48 dry gas production stood at 112.3 bcf/day on Wednesday, up 4.0% year-over-year. Demand in the same region was recorded at 76.3 bcf/day, a 2.4% increase from the prior year. Net LNG flows to US export terminals decreased by 4.7% week-over-week to 18.5 bcf/day. These operational figures, sourced from BNEF, indicate a robust domestic production environment despite the dip in export activity.

Production Growth Offsets Demand Concerns

The Edison Electric Institute reported that US lower-48 electricity output rose 16.1% year-over-year to 94,427 GWh in the week ended September 12. Over the trailing 52 weeks, output increased 3.3% to 4,405,549 GWh, reflecting sustained industrial and residential consumption. Despite this demand strength, the US Energy Information Administration projects that storage levels will reach 3,985 bcf by the end of October. This would mark the highest level in a decade and sit 5% above the five-year average, signaling a potential oversupply scenario.

The EIA also raised its 2027 US dry natural gas production estimate to 116.0 bcf/day, up from 115.3 bcf/day in July. This upward revision in long-term supply forecasts adds to the bearish medium-term narrative, as increased production capacity could outpace demand growth. The combination of record-high storage projections and expanding production creates a structural headwind for gas prices, even as short-term weather and inventory factors provide intermittent support.
