US Gas Stocks Rise as Seasonal Surplus Widens
EIA reports an 80 Bcf build and a slightly wider seasonal surplus. South Central's remaining deficit keeps winter price risk in view.

US working natural gas inventories rose 80 billion cubic feet, according to the EIA's October 29, 2026 storage report. The build, for the week ended October 23, brought stocks to 3,724 Bcf and slightly widened the surplus over the five-year average as winter approaches.
The seasonal cushion increased to 38 Bcf from 35 Bcf a week earlier, reversing the narrowing we covered in US Gas Storage Cushion Shrinks Again. EIA's October 22 supplement confirms the earlier surplus. We now have a little more gas above the seasonal benchmark available to meet winter withdrawals. For your gas holdings, that weakens the argument that the national inventory cushion is steadily disappearing, although the improvement is small.
The regional balance still leaves a reason for caution. EIA's October 29 table puts South Central stocks 28 Bcf below their five-year average, with salt storage 36 Bcf below its benchmark, calculated from the table's reported levels. In its November 16, 2015 storage explanation, EIA says salt caverns provide high withdrawal rates relative to their capacity. That gives the remaining salt-storage shortfall a practical significance: inventories in facilities capable of releasing gas quickly are still below normal, even while the national total is above it.
Does the wider cushion make us bearish on gas producers? We would be slower to pay for an earnings forecast built on an increasingly tight national storage balance, because this week's comparison moved in the other direction. But the report measures stored gas, without showing what a producer will receive for its winter sales. Your exposure still depends on the selling price, the volume available to sell and the share already hedged. A small improvement in inventories gives us a reason to challenge a scarcity assumption, without supplying a replacement price forecast.
For your mining holdings, more gas in storage offers some protection against demand exceeding current supply during winter. Yet the national surplus cannot establish that fuel will be inexpensive at a particular operation. The South Central deficit is a reminder that inventories differ by region, while EIA's storage explanation distinguishes the amount stored from the rate it can be withdrawn. We would keep that distinction in any winter cost estimate: enough gas in aggregate and enough gas delivered when needed are separate conditions. This release establishes neither a winter price ceiling nor a shortage.
We will watch EIA's November 5 storage release for another widening of the cushion, then its November 10 outlook for revised production and demand forecasts.
