Natural Gas EIA Storage — October 9, 2026

EIA Weekly Natural Gas Storage Analysis: 2026-10-09

Executive Summary

For the week ending October 9, 2026, working gas in underground storage increased by 67 Bcf to reach 3,567 Bcf. Inventories sit 45 Bcf (+1.3%) above the five-year average, though they trail year-ago levels by 143 Bcf (-3.9%). The storage trajectory reflects steady shoulder-season injections driven predominantly by the Midwest and East, while persistent deficits in the South Central salt facilities continue to temper aggregate surplus expansion.

Storage Snapshot

  • Total Lower 48 Storage: 3,567 Bcf
  • Weekly Net Change / Implied Flow: +67 Bcf (compared to 3,500 Bcf in the prior week)
  • Historical Comparison: Working gas sits 143 Bcf below the year-ago level of 3,710 Bcf (-3.9%), but 45 Bcf above the 5-year average of 3,522 Bcf (+1.3%).
  • Regional Breakdown & Divergences:
    • Midwest: +27 Bcf build to 1,037 Bcf (+2.0% vs. 5-yr avg).
    • East: +22 Bcf build to 884 Bcf (+3.3% vs. 5-yr avg).
    • South Central: +21 Bcf total build to 1,097 Bcf (-3.1% vs. 5-yr avg), split between:
    • Salt: +9 Bcf to 236 Bcf (-15.4% vs. 5-yr avg; -21.9% vs. year-ago).
    • Nonsalt: +12 Bcf to 861 Bcf (+0.9% vs. 5-yr avg).
    • Mountain: +2 Bcf build to 255 Bcf (+5.4% vs. 5-yr avg).
    • Pacific: -5 Bcf net draw to 294 Bcf (+6.5% vs. 5-yr avg).

The Midwest and East accounted for nearly three-quarters of the total net injection. Conversely, the Pacific recorded an atypical early draw of 5 Bcf, while South Central salt inventories remain deeply depressed relative to historical norms.

Implications

The +67 Bcf implied build points to a balanced-to-loosening domestic physical market as the injection season approaches its final weeks. Total storage pacing slightly above the five-year norm maintains adequate inventory cushion heading into the winter heating season, keeping front-month natural gas (NG) pricing pressures range-bound.

However, the continued structural deficit in South Central salt storage (-15.4% versus the 5-year average) signals limited fast-cycling flexibility along the Gulf Coast. Any sudden early-winter demand spikes or liquefied natural gas (LNG) feedgas surges could quickly tighten prompt regional deliverability. No revisions or reclassifications were reported in this release.

Risks and Context

  • Shoulder-Season Transition: With approximately three to four weeks remaining in the traditional injection season, the trajectory toward peak storage remains sensitive to late-October weather demand and heating degree day (HDD) realization.
  • Regional Deliverability: The pronounced deficit in Gulf Coast salt caverns represents an asymmetric risk: while northern consuming regions (East and Midwest) are well-supplied entering winter, southern balancing flexibility is constrained, heightening vulnerability to localized volatility if early freezes impact production or spark heating load.
