US Gas Stocks Rise 77 Bcf as Surplus Widens
EIA's latest build takes gas storage to 3,801 Bcf and widens the seasonal cushion, weakening the scarcity case for winter producer earnings.

US working natural gas inventories rose 77 billion cubic feet to 3,801 Bcf, according to the EIA's November 5 storage report. The release covers the week ended October 30, 2026. The seasonal surplus widened again, giving gas producers a larger inventory cushion to contend with as they head into winter.
The surplus over the five-year average reached 54 Bcf, compared with 38 Bcf a week earlier, verified in EIA's October 29 supplement. In US Gas Stocks Rise as Seasonal Surplus Widens, we described a small improvement in that cushion. The latest reporting week extends the improvement: inventories rose faster than their seasonal benchmark. For your gas holdings, an earnings case that relies on the national surplus steadily disappearing now faces another week of evidence running against it.
The regional gaps remain. Calculated from EIA's November 5 table, South Central stocks are 13 Bcf below their five-year average, while the region's salt facilities are 26 Bcf below theirs. EIA's November 16, 2015 storage explanation says salt caverns provide very high withdrawal rates relative to their working gas capacity. Those facilities can release gas quickly, so their remaining deficit deserves attention even with national inventories above average. The amount stored and the speed at which it can reach the market are different constraints.
Does the bigger cushion mean you should sell gas producers? We would first test the winter selling price built into your earnings estimate. More stored gas weakens the argument for paying a premium based solely on scarcity, especially for production exposed to market prices. EIA's October 6 outlook already forecast that production increases would offset rising LNG exports and keep inventories above average. This storage report is consistent with the inventory direction in that forecast, although it cannot establish whether production, weather or export demand drove this week's build.
For your mining holdings, more gas in storage offers a larger buffer if winter consumption exceeds incoming supply. That can soften one source of fuel cost risk, but the national total cannot establish an operation's delivered bill. Your mine's supply region, purchasing contract and delivery arrangements determine how wholesale price changes reach its costs. We would want those details before raising a margin forecast on the strength of a storage build. Nor does the salt-storage deficit alone establish a shortage: the report measures inventories, without proving that withdrawal capacity or deliveries will fall short of demand.
We will watch EIA's November 10 outlook for revised production and LNG forecasts, then its November 13 storage release for whether the seasonal cushion widens again.
