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 $16.99 on Jan 4, 1989, WTI climbed to $24.62 by Apr 20, 1989, a 45% gain. The steepest fall within the year ran from $24.62 on Apr 20, 1989 to $17.91 on Aug 1, 1989, a 27% drop. The price finished the year 26% above its first 1989 close of $17.38. The price moved by 5% or more in a single day 7 times.

The monthly average was lowest in February ($17.94) and highest in December ($21.10). In September 2026 dollars (CPI-U), the 1989 average is $53.37, lower than 2025's real average by $15.07 (22.0%).
