Reading oil beyond the weekly inventory number

Separate headline from composition

A crude draw can coexist with weak products or falling refinery demand. Read crude, gasoline, distillates, Cushing and refinery utilisation together.

Use the curve as context

Backwardation can signal tighter prompt supply, while contango can indicate looser availability or storage incentives. Neither structure is a standalone timing signal.

Plan for discontinuous risk

Oil can gap on OPEC+ decisions, sanctions, conflict and shipping disruption. A technically tidy setup can be invalidated before normal liquidity returns.

Read the balance behind the headline

The EIA Weekly Petroleum Status Report provides US petroleum supply and disposition data. Start with its reporting period and release schedule, then separate commercial crude inventories from the Strategic Petroleum Reserve. They are different categories. Read refinery activity, imports, exports and product inventories alongside the crude change rather than assuming that one number describes the entire oil market.

The report is a US data source. It does not by itself establish the global supply-demand balance or explain every change in Brent. Use the report’s definitions and notes when comparing weeks, and record whether a figure is preliminary, estimated or revised.

An illustrative stock-flow check

Suppose, using invented numbers, imports fall by three units, refinery use rises by one unit and production and other flows are unchanged. These changes would reduce the amount left in storage by four units relative to the prior comparison. A stock draw in this example could therefore occur without a broad increase in final consumer demand.

This is a teaching balance, not an estimate of actual barrels or a forecast. A practical reading log should identify the components that changed, the missing components and any reconciliation item. Keep the observed inventory change separate from your explanation for it.

Compare contract months explicitly

A futures curve compares prices for different delivery months. In a simple two-contract example, a nearby price of 80 and a later price of 82 produces a nearby-minus-later spread of −2. Reversing the prices produces +2. The first is an upward-sloping comparison, commonly called contango; the second is a downward-sloping comparison, commonly called backwardation.

These invented prices illustrate subtraction only. Specify exchange, contract month, currency, units and observation time before comparing actual contracts. A continuous chart may roll between contracts and may be adjusted; it is not automatically an executable price for a specific delivery month.
