Monthly averages are EIA's published figures. Brent − WTI is the average over dates with both prices published, so it can differ from the difference between the two monthly averages. Inflation-adjusted columns use CPI-U for each month, expressed in September 2026 dollars; “—” means CPI-U for that month is not available.
