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 $13.89 on Feb 16, 1994, WTI climbed to $20.72 by Jun 17, 1994, a 49% gain. It was below $20 on 240 days. Although the annual average fell, prices ended the year higher than they started: $14.52 on Jan 3, 1994 against $17.77 on Dec 30, 1994. The steepest fall within the year ran from $20.72 on Jun 17, 1994 to $16.60 on Dec 15, 1994, a 20% drop.
Brent traded below WTI throughout 1994: its monthly average was lower in every month, and on the 247 matched dates it averaged $1.36 less. Brent averaged $15.86, down $1.15 (6.8%) from 1993.
The monthly average was lowest in March ($14.68) and highest in July ($19.66). In September 2026 dollars (CPI-U), the 1994 average is $39.11, lower than 2025's real average by $29.33 (42.9%). The 1990s as a whole averaged $19.70, so 1994 ran below its decade. Of 40 complete years with an EIA annual average, 1994 ranks 4th lowest.
