How to Interpret Crude Oil Inventories Changes

• Revisions: Prior-period revisions can change the interpretation of a release even when the current period is in line with expectations.
• Context: The same numeric change can have different implications depending on the current phase of the economic cycle and the policy environment.
• Related indicators: Confirmation from related indicators strengthens any signal from Crude Oil Inventories alone.
