Impact of Iran War on U.S. Gasoline Prices

Optimistic Predictions Versus Expert Warnings

President Donald Trump predicted that gasoline prices would significantly decline following the end of the conflict with Iran. Speaking from the Oval Office on May 11, he expressed confidence that prices would fall swiftly once the war concluded. At that time, the average nationwide price for regular gas stood at a high of $4.52 per gallon.

However, energy analysts present a less optimistic view. They caution that gas prices in the U.S. might not drop to pre-war levels within the current year. Even if the conflict were to end immediately, prices would likely remain elevated for some time. Data from before the escalation show that the national average was $2.98 per gallon.

Denton Cinquegrana, chief oil analyst at Oil Price Information Service, indicated that returning to those price levels could take until the second half of 2027.

Current Gas Price Trends

Gasoline prices in the U.S. were on a decreasing trend prior to the escalation of conflict on February 28, when joint strikes on Iran by the U.S. and Israel began. Prior to the war, there was optimism about reducing prices, and the Trump administration celebrated perceived economic benefits for American families. However, the continuation of the Iran war reversed these trends.

The Strait of Hormuz, a critical passage for oil transport, faced significant disruptions, causing global oil prices to rise. These disruptions have significantly impacted gas prices in the U.S.

Currently, the national average gas price is around $4.5 per gallon, a notable increase from pre-conflict levels. In California, prices have exceeded $6 per gallon, while in Mississippi, they remain just under $4 per gallon.

Factors Influencing Future Prices

Experts highlight that ending the war alone won’t sufficiently lower gas prices. A key factor is the restoration of regular oil shipments through the Strait of Hormuz.

Patrick De Haan, head of petroleum analysis at GasBuddy, emphasized the need to fully reopen the strait for oil shipments to see any potential price decreases. Even then, it could take a considerable time to normalize.

Cinquegrana noted that even with the reopening, the process of normalizing oil flow would depend on how much oil can pass through initially. It could take weeks for shipments to reach their destinations once the strait resumes operations.

If optimal conditions are met, normal oil flows might begin by early June, with market impacts potentially extending into July. Returning to prewar price levels could take more than a year.

Recent Developments and Analyst Outlook

Recently, there have been modest drops in gas prices, perhaps due to optimism regarding potential peace negotiations. Nonetheless, analysts remain cautious about the future.

Adam Turnquist, Chief Technical Strategist for LPL Financial, indicated that despite recent declines, concerns about supply persist. Current Brent futures remain significantly above preconflict prices, which maintains upward pressure on gasoline costs.

De Haan advises caution, noting that until there is a formal agreement and significant oil transit through the Strait, national average prices will likely remain high, well above the $4 per gallon mark.
