How to read the EIA oil inventory report

A headline about an oil inventory draw sounds simple: less oil in storage must mean higher prices. The useful question is what changed, why it changed, and whether other data supports the same explanation. This guide is a reading routine, not a prediction of the next market move.

Start with the original report

The U.S. Energy Information Administration publishes the Weekly Petroleum Status Report. Use its release schedule rather than assuming a holiday week follows the usual timetable. Note both the release date and the week the figures describe: publication day and measurement period are different.

• Open the EIA Weekly Petroleum Status Report, including the balance sheet and stocks tables.
• Record the units before comparing numbers. A stock level in barrels is different from a production or refinery flow in barrels per day.
• Separate commercial crude stocks from the Strategic Petroleum Reserve and from gasoline or distillate inventories.

Work through a hypothetical draw

Suppose commercial crude stocks fall from 430 million to 427 million barrels. The weekly change is minus 3 million barrels, about minus 0.70% of the starting stock. Those are invented figures for arithmetic practice, not the latest report. The calculation describes a change in a stock; it does not measure a percentage change in demand.

Now ask what could account for it. Did refinery inputs rise? Did crude imports fall or exports rise? Did production change? A shipping delay can affect a weekly observation without establishing a durable trend. Read the balance components together rather than choosing whichever one supports your first impression.

Check the products and the context

Refiners turn crude into products. A crude draw alongside a gasoline build tells a different story from draws across both. Product supplied is a useful consumption indicator, but a single week's observation is not a direct survey of every driver's purchases. Compare several weeks and read the report's notes before labeling a move a demand boom.

For your own notes, use four columns: observation, possible explanation, evidence needed, and uncertainty. For example: crude stocks fell; refinery runs may explain part of it; compare inputs and product stocks; shipping timing remains uncertain. This makes your reasoning easier to revisit next week.

Why a draw can coincide with a price fall

A market price responds to information relative to expectations, along with many other influences. Even an accurately read report cannot isolate all of them. Without a documented expectations source, avoid calling the release a surprise. A chart that moves after publication does not by itself establish that one table caused the move.
