U.S. gasoline prices fell below $4 per gallon for the first time since mid-April, reaching a national average of $3.997, according to GasBuddy data reported by HuffPost.

The price decline follows a preliminary agreement between the U.S. and Iran to end their conflict and reopen the Strait of Hormuz, a vital waterway for global oil supplies that had been virtually closed since February 28. President Trump signed the memorandum on Wednesday, with at least 10 commercial vessels traversing the strait by Thursday.

Brent crude fell 1.4% to $78.46 a barrel, while West Texas Intermediate dropped 2.2% to $75.10 a barrel. Patrick De Haan of GasBuddy noted that prices could continue falling if progress with Iran continues, potentially reaching below $3 per gallon by early 2027.

The price drop offers some relief to the Trump administration amid rising consumer costs and upcoming midterm elections. However, experts warn that lasting relief depends on clearing mines from the strait and stabilizing exports, a process that could take weeks or months.

Americans have spent about $46 billion more on gasoline since the war began in February. Despite recent declines, prices remain 90.8 cents higher than last year. The U.S. faces potential supply shortages due to high domestic demand and exports, with gasoline stocks at their lowest seasonal level in a decade.
