Much of what is written about oil prices is built on a handful of regular public reports. Learning what those reports contain, and how to read them, lets you check commentary for yourself instead of relying on headlines alone.
This guide introduces three widely cited sources and offers some practical tips for interpreting them. It describes the reports in general terms; always check the publisher's own documentation for current definitions and release schedules.
The EIA Weekly Petroleum Status Report
The U.S. Energy Information Administration (EIA) is the statistical agency of the U.S. Department of Energy. Its Weekly Petroleum Status Report is one of the most closely followed releases in the oil market because it comes out frequently and covers the large U.S. market in detail.
The report includes estimates of U.S. commercial crude oil inventories, stocks of gasoline and distillates (which include diesel and heating oil), refinery inputs and utilisation, imports and exports, and implied product demand. It also reports stocks at Cushing, Oklahoma, the delivery point for the main U.S. crude futures contract.
Reading inventory changes
The headline figure most people notice is the weekly change in crude inventories. A build means stocks rose; a draw means they fell. On its own, a single week tells you little. It is more useful to compare the change with what is normal for that time of year, because inventories follow seasonal patterns linked to refinery maintenance and driving seasons.
It also helps to look at crude and products together. A crude draw combined with large gasoline builds might simply mean refineries processed more crude, not that demand rose.
The IEA Oil Market Report
The International Energy Agency (IEA) is an intergovernmental organisation based in Paris. Its monthly Oil Market Report provides a global view: estimates and forecasts of world oil demand and supply, refinery activity, inventories in developed economies and trade flows.
Because it covers the whole world, the IEA report is useful for understanding the bigger picture behind weekly U.S. data. Forecasts are revised as new information arrives, so it is worth paying attention to the direction of revisions as well as the numbers themselves.
The OPEC Monthly Oil Market Report
The Organization of the Petroleum Exporting Countries (OPEC) publishes its own Monthly Oil Market Report. It includes the organisation's view of world demand and non-OPEC supply, and it reports production estimates for member countries based on secondary sources as well as direct communication.
Comparing OPEC's demand outlook with the IEA's can be informative. The two organisations sometimes differ in their assumptions, and the gap between them is itself something analysts discuss.
Other useful sources
- Exchange data: futures exchanges publish settlement prices and open interest for their contracts.
- Positioning reports: in the United States, the Commodity Futures Trading Commission publishes weekly Commitments of Traders data showing how different groups of participants are positioned in futures markets.
- Rig counts: weekly counts of active drilling rigs, published by an oilfield services company, are often used as a rough indicator of future U.S. drilling activity.
Common pitfalls
Several mistakes come up again and again when people read oil data:
- Over-reading one data point. Weekly figures can be noisy and are sometimes revised. Trends over several weeks are more meaningful.
- Ignoring expectations. Markets often react to the difference between a figure and what was expected, not to the figure itself.
- Mixing up units and scope. Some figures are in barrels, others in barrels per day; some cover only commercial stocks, others include strategic reserves.
- Treating forecasts as facts. Demand and supply forecasts are estimates that change. They describe a view, not a certainty.
A simple reading routine
If you want to follow the market without becoming overwhelmed, a light routine works well. Read the summary of the weekly EIA release and note whether crude and product stocks moved more or less than usual for the season. Once a month, skim the summaries of the IEA and OPEC reports and note any change in demand forecasts. Over time, you will build an intuitive sense of what is normal and what is genuinely surprising.
Bottom line
Public reports from the EIA, IEA and OPEC are the raw material for most oil market analysis. Reading them directly, with attention to seasonality, expectations and revisions, is one of the best ways to understand why prices move.
