US Natural Gas Storage Rises Most Since July

US energy companies added 85 billion cubic feet of natural gas to storage on the week that ended October 2nd, 2026, the most since late June following a lower restocking period in the Spring and Summer. The figure was above the preliminary estimate of 79 bcf. The increase lifted outstanding inventory to 3.500 trillion cubic feet, 3.6% below the corresponding period of the previous year as higher capacity in export plants and lower global supply from the Middle East incentivized companies to sell LNG abroad.

US energy companies added 64 billion cubic feet of natural gas to storage during the week ending September 25, 2026, matching market expectations. The injection was above the 56 bcf added during the same week last year but below the five-year seasonal average of 80 bcf. Total inventories increased to 3.415 trillion cubic feet, leaving stocks 3.9% below year-ago levels but approximately 2.4% above the five-year average for the period. The latest build was also larger than the 53 bcf injection recorded in the previous week through September 18. Looking ahead, preliminary estimates point to a further 79 bcf increase in storage for the week ending October 2. That expected build would be slightly above the 77 bcf added during the comparable week in 2025, but remains below the five-year average injection of 96 bcf.

US natural gas storage increased by 44 billion cubic feet in the week ended September 11, 2026, slightly below market expectations of a 49 bcf injection. The build was significantly smaller than the 87 bcf increase recorded during the same week last year and the five-year average injection of 74 bcf for the period from 2021 to 2025. Total working gas in storage rose to 3.298 trillion cubic feet, leaving inventories around 3.6% below levels recorded in the corresponding week a year earlier but approximately 3.7% above the five-year average. The latest data followed a 40 bcf injection in the previous week ended September 4.
