EIA Crude Oil Inventories
The weekly US crude oil supply report from the Energy Information Administration — the highest-impact scheduled event for crude oil futures (CL, MCL).
What is EIA Crude Oil Inventories?
The EIA Weekly Petroleum Status Report is the US Energy Information Administration’s weekly supply data release for crude oil, gasoline, distillates, and refinery utilization. It releases every Wednesday at 10:30 AM Eastern Time (delayed to Thursday when Monday is a federal holiday). The headline number is the week-over-week change in commercial crude oil inventories, measured in millions of barrels.
For crude oil futures traders, EIA is the single highest-impact scheduled event of the week. WTI crude futures (CL on CME, MCL for the micro contract) routinely move 50-150 cents within 60 seconds of the 10:30 AM release on a meaningful inventory surprise. The report also moves Brent crude, RBOB gasoline futures, and natural gas-correlated trades.
The Tuesday afternoon API report (American Petroleum Institute) is a private-sector predecessor that often previews the direction of the EIA print. Crude oil futures move on the API release as well, though with smaller and less reliable reactions than the official EIA data.
How EIA Crude Oil Inventories works
EIA mechanics for futures traders:
1. Release schedule. Weekly on Wednesday at 10:30 AM Eastern Time. If Monday is a federal holiday, the release shifts to Thursday at 11:00 AM ET.
2. Three numbers move markets. Crude oil inventory change (headline), gasoline inventory change, distillate inventory change. Refinery utilization rate is a secondary input. Markets react to all four versus consensus.
3. The build/draw direction matters. A larger-than-expected draw (inventory decrease, bullish for crude) lifts CL. A larger-than-expected build (inventory increase, bearish for crude) drops CL. Consensus is published Tuesday afternoon by major energy desks.
4. Gasoline and distillates can override. A crude build with a large gasoline draw often produces a bullish CL move — markets interpret the gasoline draw as strong demand pulling crude through refineries.
5. Volatility profile. CL typically moves 50-150 cents in the first 60 seconds on a meaningful surprise. MCL (micro WTI) is proportional. RBOB gasoline futures (RB) often move sympathetically. Brent (also affected) trades on ICE, not CME.
6. Prop firm rules. EIA is on most futures prop firms’ news-restriction lists for funded accounts trading crude. The 10:30 AM ET release timing means cash equity is already trading, so liquidity is good — but the move size makes flat-into-EIA mandatory for funded accounts.
Worked example
Concrete EIA example — March 25, 2026:
Consensus: -1.5 million barrel crude draw (slight bullish bias). CL trading at $73.40 going into 10:30 AM ET.
The release: -5.8 million barrel draw (much larger draw than expected, very bullish), gasoline -2.1MB (also bullish), distillates -1.4MB (bullish). Across-the-board bullish surprise.
10:30:01 AM: CL spiked from $73.40 to $74.65 in 18 seconds — a 125-cent move. By 10:35 AM, CL had pulled back to $74.20, then continued higher to $74.85 by 11:00 AM. The full move from pre-release to one-hour peak was ~145 cents.
A trader holding 1 MCL contract short going in would have seen -100 cents ($100 per contract) within 60 seconds, with continued pain through 11:00 AM. Flat into EIA is the universal pro practice.
Why traders fail EIA Crude Oil Inventories
Holding CL or MCL through 10:30 AM Wednesday on a funded account. EIA is on every major prop firm’s news-restriction list for crude oil futures. The 100-150 cent moves in 60 seconds will breach drawdown on any aggressive position.
Trading the initial spike. The first 30 seconds after 10:30 AM is dominated by algos. Slippage of 10-20 cents on market orders is normal. Wait for the dust to settle until 10:35-10:40 AM before entering discretionary positions.
Ignoring gasoline and distillates. A crude build (bearish) with a large gasoline draw (bullish) often produces a bullish CL move because the gasoline draw signals strong demand. Read all three numbers.
Treating Tuesday API as equivalent to Wednesday EIA. API often previews EIA direction but with smaller reactions and frequent divergences. Don’t size for EIA based on API; the two are correlated but not identical.
Frequently asked questions about EIA Crude Oil Inventories
When is EIA released?
Every Wednesday at 10:30 AM Eastern Time. If Monday is a federal holiday, the release shifts to Thursday at 11:00 AM ET.
What does EIA measure?
Weekly changes in US commercial crude oil inventories, gasoline stocks, distillate stocks, and refinery utilization rates. The crude inventory change is the headline number futures traders watch most closely.
How much does EIA move crude oil futures?
Typically 50-150 cents on WTI crude (CL) in the first 60 seconds on a meaningful surprise. The micro contract (MCL) sees proportional moves. RBOB gasoline futures (RB) often move sympathetically.
Should I trade through EIA on a prop firm account?
Most futures prop firms prohibit holding crude oil positions through the 10:30 AM EIA release on funded accounts. Even on personal accounts, the 100+ cent moves in 60 seconds will sweep narrow stops.
What is the API report and how does it relate to EIA?
The American Petroleum Institute publishes a private-sector inventory estimate Tuesday afternoon, previewing the direction of Wednesday's EIA report. API moves crude futures but with smaller reactions than EIA. Frequent divergences between API and EIA mean traders can't rely on Tuesday's data to fully predict Wednesday's move.
