U.S. gasoline prices remain stubbornly high even as oil futures plunge 20% following news of a fragile cease-fire between the United States and Iran. The average cost of regular gasoline hit $4.16 per gallon on Wednesday, the highest level since August 2022 and up nearly 40% since the conflict began. AAA data shows prices have been climbing since Iran blockaded oil exports through the Strait of Hormuz.

Energy analysts note that gasoline prices typically follow oil's trajectory but with a significant delay. While crude oil prices can drop quickly, gasoline prices descend slowly due to the time required for oil transportation, refining, and distribution. Raymond James analyst Pavel Molchanov explains that the lag between falling oil prices and lower pump prices can stretch from 10 to 14 days, compared to just 3-5 days when prices rise.

Gas stations must first sell through their existing inventory purchased at higher costs before reflecting lower wholesale prices. Energy companies also have profit incentives to maintain elevated prices as long as possible. Despite Wednesday's oil price drop potentially lowering pump prices by 45 cents per gallon, gasoline will likely remain well above pre-war levels of $2.98 per gallon. The uncertain cease-fire and damaged regional production facilities mean prices may stay elevated even if the Strait of Hormuz reopens.
