⚠️ Direct Access Status¶
A direct web_fetch of https://www.eia.gov/petroleum/supply/weekly/ on 2026-09-29 returned the landing-page table list (tables 1–14 + appendices) but no embedded weekly data values. The product-supplied page https://www.eia.gov/dnav/pet/pet_cons_wpsup_k_w.htm returned only the methodology footer ("Finished motor gasoline production and product supplied includes a weekly adjustment applied only to the U.S. total…").
The quantitative claims below are triangulated from the discovery report at discovery-2026-09-29, which read the WPSR series directly on 2026-09-29 before the KB ingest began. Any reader relying on the precise series values should re-fetch the underlying CSVs/XLSXs from the table links listed below rather than rely on this article.
Quantitative Claims (Triangulated)¶
| Metric | Value | Period | Source |
|---|---|---|---|
| Finished motor gasoline product supplied (4-week avg) | 8.779 mb/d | 4 weeks ending 2026-09-18 | discovery-2026-09-29 |
| 4-week YoY change | −69 kb/d (−0.78%) | vs same 4-week window 2025 | discovery report (calculated from EIA Table 1) |
| Baseline 4-week avg (2025) | 8.848 mb/d | same 4-week window 2025 | discovery report (calculated from EIA Table 1) |
| Single-week product supplied | 8.847 mb/d | week ending 2026-09-18 | discovery report |
| Prior-week product supplied | 8.798 mb/d | week ending 2026-09-11 | discovery report |
Underlying Tables (Source-of-Record Links)¶
The WPSR landing page lists these weekly tables; each is published as CSV, XLS, and PDF:
- Table 1 — U.S. Petroleum Balance Sheet CSV XLS PDF — product-supplied for gasoline (and distillate, jet, residual)
- Table 2 — U.S. Inputs and Production by PAD District
- Table 3 — Refiner and Blender Net Production
- Table 4 — Stocks of Crude Oil by PAD District, and Stocks of Petroleum Products, U.S. Totals
- Table 5 — Stocks of Total Motor Gasoline and Fuel Ethanol by PAD District
- Table 5A — Stocks of Total Motor Gasoline and Fuel Ethanol by PAD District (with Total Gasoline by Sub-PADD)
- Table 6 — Stocks of Distillate, Kerosene-Type Jet Fuel, Residual Fuel Oil, and Propane/Propylene by PAD District — distillate inventory series
- Table 7 — Imports and Exports of Crude Oil and Products
- Table 8 — Preliminary Crude Imports by Country of Origin
- Table 9 — U.S. and PAD District Weekly Estimates
- Table 11 — Spot Prices of Crude Oil, Motor Gasoline, and Heating Oil
- Table 12 — Spot Prices of Ultra-Low Sulfur Diesel Fuel, Kerosene-Type Jet Fuel, and Propane
- Table 14 — U.S. Retail Motor Gasoline and On-Highway Diesel Fuel Prices — retail diesel series
Why This Source Matters¶
The WPSR is the cleanest, fastest-updating, decision-relevant product signal in the US data ecosystem. Within the KB's existing q2-price-impact and refined-products-as-shock-center frameworks:
- Weekly gasoline product-supplied is the only high-frequency US proxy for "what consumers are actually taking delivery of" (vs. EIA STEO monthly averages). The −0.78% YoY is small enough to be inside seasonal noise, but the 4-week rolling structure smooths volatility.
- Weekly distillate inventory (Table 6) is the only high-frequency US proxy for the inventory operational floor; cross-references the 2026-09-09-eia-steo-september-2026-petroleum-products monthly forecast of <100 mb.
- Weekly US retail diesel (Table 14) is the cleanest US proxy for retail-price pass-through; cross-references the 2026-09-09-eia-steo-september-2026-prices monthly forecast.
The discovery report flagged this WPSR as Candidate 1 indicator data for the proposed Distillate Inventory Operational Floor monitoring question — "Where are US, European, and Asian distillate inventories relative to operational minimums?"
Caveats¶
- EIA "product supplied" is a proxy for consumption (implied deliveries to wholesale + retail), not real-time pump draw. It captures implied demand, not cash transactions.
- −0.78% YoY 4-week is small enough to be inside seasonal noise. Do not over-interpret as a structural break.
- YoY base effect: 2025 H2 included some post-pandemic normalization recovery, which widens the 2026 H2 YoY gap for non-structural reasons.
- Direct fetch limitation: this article's quantitative claims are triangulated from the discovery report. Re-fetch Tables 1, 6, and 14 directly for any downstream citation requiring precise figures.

Concepts¶
- demand-destruction-dual-risk — dual-risk framework; the 8.779 mb/d 4-wk avg gasoline product supplied (with −69 kb/d YoY) is the cleanest US price-elastic-demand signal in the new source batch
- refined-products-as-shock-center — products-as-binding-constraint; the gasoline product-supplied series complements the distillate inventory story
- oecd-inventory-operational-floor — OECD inventory floor; the WPSR Table 1/4/6/14 series are the weekly inventory operational-floor tracking mechanism
