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.
From $18.02 on Jan 18, 2002, WTI climbed to $32.68 by Dec 27, 2002, an 81% gain. The price finished the year 48% above its first 2002 close of $21.13. The steepest fall within the year ran from $30.85 on Sep 23, 2002 to $25.28 on Nov 13, 2002, an 18% drop. Second-half prices averaged $28.31, up from $24.03 in the first half.

The monthly average was lowest in January ($19.72) and highest in September ($29.66). In September 2026 dollars (CPI-U), the 2002 average is $49.03, lower than 2025's real average by $19.40 (28.4%).
