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 $15.43 on Jun 20, 1990, WTI climbed to $41.07 by Oct 11, 1990, a 166% gain. The price moved by 5% or more in a single day 38 times. Second-half prices averaged $29.15, up from $19.79 in the first half. The steepest fall within the year ran from $41.07 on Oct 11, 1990 to $25.30 on Dec 12, 1990, a 38% drop.
The Brent–WTI spread changed sign during 1990: Brent's monthly average was below WTI's in 9 of 12 months and above it in the rest, for an average of −$0.79 on 256 matched dates. Brent averaged $23.76, up $5.53 (30.3%) from 1989.
The monthly average was lowest in June ($16.70) and highest in October ($36.04). In September 2026 dollars (CPI-U), the 1990 average is $63.24, lower than 2025's real average by $5.20 (7.6%). The 1990s as a whole averaged $19.70, so 1990 ran above its decade. Of 40 complete years with an EIA annual average, 1990 ranks 14th lowest.
