Two U.S. government reports do more to move commodity prices week to week than any single headline: the Energy Information Administration’s crude oil inventory count and the Commodity Futures Trading Commission’s trader-positioning data. In the week ended December 5, 2025, EIA commercial crude stocks fell 1.8 million barrels to 425.7 million — routine by historical standards, yet still the kind of number that moves futures, because of how directly it feeds the tape.
Neither report is exotic. Both are published on fixed schedules, built from standardized surveys, and available free to anyone. What makes them load-bearing for commodity markets is less the data itself than the plumbing around it — who is required to report, how fast the numbers travel, and how thin the window is between collection and release. Understanding that plumbing explains more about a Wednesday-morning oil price swing than any single week’s barrel count does.
What Is the Weekly Petroleum Status Report, and Why Does the Market Wait for It?
The Weekly Petroleum Status Report is compiled and released by the U.S. Energy Information Administration, the statistical arm of the Department of Energy. Traders watch it because it is the only comprehensive, standardized, government-verified count of U.S. crude and product stocks published on a weekly cadence — everything else is estimate or survey.
The report itself is released in two stages: a partial version after 10:30 a.m. Eastern and a fuller version after 1:00 p.m., according to EIA’s own release page. It covers crude oil stocks broken out by Petroleum Administration for Defense (PAD) district, total motor gasoline and fuel ethanol inventories, refiner and blender production and inputs, and preliminary crude imports by country of origin, spread across fourteen numbered tables. It is issued in PDF, CSV, and Excel formats, and EIA’s own release calendar lists the following report — covering the week ended August 14, 2026 — for publication on August 26, 2026.
That predictability is the point. A market that knows exactly when a standardized federal count will land can build its entire short-term positioning around the release, which is precisely what happens in crude, gasoline, and distillate futures every week the report comes out on schedule.
Does the Report Cover Only Crude, or the Whole Barrel?
The Weekly Petroleum Status Report goes well beyond a single crude number, which is part of why it moves more than one futures contract at once. Alongside crude stocks by PAD district, EIA’s release covers total motor gasoline and fuel ethanol inventories, refiner and blender net production and inputs, and preliminary crude oil imports broken out by country of origin — all organized across fourteen numbered tables, per the agency’s own release page.
The same release also carries a separate petroleum balance sheet and spot-price tables for crude, gasoline, heating oil, diesel, jet fuel, and propane. That breadth is why a single Wednesday-morning release can move gasoline futures, heating-oil futures, and crude futures within minutes of each other — refiners, distributors, and utilities are each reading the table that maps to their own book, on the same clock.
The multi-product structure also explains why headline commentary that reduces the report to “the oil number” regularly misses the more consequential release. A crude build paired with a sharp gasoline draw ahead of a seasonal demand shift, for instance, tells a materially different story than either figure would tell in isolation — and the report is built precisely so both can be read side by side.
How Does a Number Like a 1.8-Million-Barrel Draw Actually Move a Futures Price?
A single week’s inventory change moves futures because it is compared, almost instantly, against two things: the prior week’s level and the same week a year earlier. EIA’s own summary of the week ended December 5, 2025 illustrates the mechanics — total crude stocks, including the Strategic Petroleum Reserve, stood at 837.6 million barrels, down 1.6 million barrels (0.2 percent) from the prior week.
Within that total, the split matters more than the headline. Commercial crude — the barrels actually available to refiners and traders, excluding the government-held Strategic Petroleum Reserve — fell 1.8 million barrels to 425.7 million, while the SPR itself rose 0.2 million barrels. A trader reading only the combined total would miss that the commercial draw was larger than the headline number suggests, since SPR movements reflect government policy, not market supply and demand.
Year-over-year framing adds another layer: EIA’s data put total crude stocks 23.1 million barrels, or 2.8 percent, above the same week in 2024. A single week’s draw read against a rising year-over-year base tells a different story than the same draw read in isolation — which is exactly why traders and desks parse both figures rather than the weekly change alone.
| Metric | Value | Change vs. prior week |
|---|---|---|
| Total crude stocks (incl. SPR) | 837.6 million barrels | −1.6 million (−0.2%) |
| Commercial crude (excl. SPR) | 425.7 million barrels | −1.8 million |
| Strategic Petroleum Reserve | 411.9 million barrels | +0.2 million |

What Is the CFTC’s Commitments of Traders Report, and What Does It Add?
Where EIA measures physical barrels, the Commodity Futures Trading Commission’s Commitments of Traders report measures who is betting on them. The CFTC publishes it weekly, ordinarily each Friday at 3:30 p.m. Eastern, and it reflects open interest as of the preceding Tuesday — a three-day gap between data collection and release that the agency describes as time spent correcting and verifying the data before publication.
The report breaks open interest down by trader classification: producers, merchants, processors, and end users on one side; swap dealers, managed money, and other reportable traders on the other. Reporting thresholds apply only to traders holding positions above CFTC-set levels, so the report captures large, identifiable participants rather than the full retail tail of the market. A position in the “producer/merchant/processor/user” category is counted whether it is a hedge or a speculative bet, the CFTC notes, which means the raw numbers require some interpretation before they say anything about sentiment.
Why Do the Two Reports Sometimes Tell Different Stories?
EIA’s inventory data describes the physical market as of last week; the CFTC’s positioning data describes financial bets as of the Tuesday before that, filtered through a Friday release. The two reports are not measuring the same thing on the same clock, and treating them as interchangeable is a common source of confused market commentary.
A commercial crude draw can coincide with managed-money traders adding net-long positions, in which case the two reports reinforce each other. It can also coincide with financial players trimming length even as physical barrels tighten — a split that says more about macro positioning (rate expectations, dollar moves, index rebalancing) than about the oil market itself. Reading the barrel count without the positioning context, or the reverse, misses half of what is actually driving that week’s price action.
What Are the Blind Spots in Each Report?
Neither report is a complete picture, and both carry limitations worth stating plainly. The Weekly Petroleum Status Report is a U.S.-only count; it says nothing directly about OPEC+ production decisions, non-U.S. inventories, or seaborne flows, all of which also move global crude prices. It is also a snapshot subject to weekly revision and to distortions around holidays, when EIA itself has historically shifted release timing.
The Commitments of Traders report has its own gap: the three-day lag between the Tuesday data cutoff and the Friday release means the market is always trading on positioning that is several days stale by the time it becomes public. Large, fast-moving shifts in speculative positioning between Tuesday and Friday are invisible until the following week’s report, if they show up in the aggregate data at all. Both reports are useful precisely because they are standardized and verifiable — not because either one, alone, is complete.
What This Means for Reading the Next Report
Neither the EIA nor the CFTC report exists to forecast prices, and nothing in either release predicts what crude, gasoline, or diesel futures will do next. What both offer is a verifiable starting point: an actual barrel count and an actual record of large-trader positioning, both built on standardized federal collection rather than anecdote. The volatility that shows up around each release is less about surprise and more about a market recalibrating two real, if partial and time-lagged, pictures of physical supply and financial positioning against each other — a process that repeats, on schedule, every week the reports come out.
