What The July 16 Report Shows
EIA reported a 41 Bcf net injection into Lower 48 storage for the week ending July 10, bringing total working gas to 3,024 Bcf. Stocks were 21 Bcf below the year-earlier level and 181 Bcf above the five-year average of 2,843 Bcf.
The injection was 20 Bcf smaller than the prior week's 61 Bcf build. The five-year surplus narrowed by 4 Bcf, while the year-over-year deficit widened by 6 Bcf. Commercial buyers should read all three comparisons together instead of treating the weekly injection alone as a price call.
| Region | Working Gas | Weekly Change | Vs 5-Yr Avg | Vs Year Ago |
|---|---|---|---|---|
| East | 614 Bcf | +14 Bcf | +1.7% | -1.9% |
| Midwest | 749 Bcf | +20 Bcf | +6.2% | +3.0% |
| Mountain | 240 Bcf | +4 Bcf | +21.2% | +2.6% |
| Pacific | 319 Bcf | 0 Bcf | +21.8% | +8.5% |
| South Central | 1,103 Bcf | +3 Bcf | +2.7% | -5.2% |
| South Central salt | 324 Bcf | -5 Bcf | +9.8% | -3.6% |
| South Central nonsalt | 779 Bcf | +8 Bcf | +0.1% | -5.9% |
Commercial Buyer Read
| Signal | Market Read | Buyer Move |
|---|---|---|
| 41 Bcf injection | The weekly build was 20 Bcf smaller than the July 9 report and lifted Lower 48 working gas above 3 Tcf. | Keep heat, LNG feedgas, production, and power-sector burn in the next procurement check instead of treating one smaller build as a standalone price call. |
| 181 Bcf above five-year average | The national cushion remained healthy at 6.4%, but narrowed by 4 Bcf from the prior report. | Use the surplus as constructive supply context, then test whether regional basis and contract pass-through terms tell the same story. |
| 21 Bcf below last year | The year-over-year deficit widened by 6 Bcf even as total inventories moved above 3,000 Bcf. | Avoid presenting the five-year surplus as proof that every inventory comparison is loose or that delivered rates must decline. |
| South Central salt withdrawal | Salt storage withdrew 5 Bcf while nonsalt stocks remained 5.9% below last year. | Keep Gulf Coast, LNG-linked, and basis-sensitive exposures separate from the Lower 48 headline. |
How To Use The Number
- Keep the dates attached: this is the July 16, 2026 report for the week ending July 10.
- Separate national inventory from regional basis: Pacific stocks were 21.8% above average, while South Central nonsalt was only 0.1% above average and remained 5.9% below last year.
- Connect gas and power carefully: storage can influence gas-indexed wholesale power risk, but delivery tariffs, capacity, transmission, load shape, and contract language decide the invoice.
What Not To Infer
- A 41 Bcf injection does not guarantee lower delivered natural gas or electricity rates.
- A national five-year surplus does not remove local basis or pipeline-constraint risk.
- Weekly storage data is not a supplier quote and should not be converted into one without the customer's tariff class, load shape, and contract terms.
