Iran War Helps to Drive U.S. Diesel Prices to New High

Diesel fuel prices jumped to a record high on Friday in the United States, as the war in Iran continued to restrict the supply of energy worldwide, further squeezing businesses that rely on diesel to run their factories and equipment.

The national average price of a gallon of diesel reached $5.85 per gallon, according to the AAA motor club, up more than 55 percent since the war started. That surpassed the previous peak, set four years ago during the global energy crunch caused by Russia’s full-scale invasion of Ukraine.

Other refined petroleum products, like gasoline and jet fuel, have also soared. Gasoline cost $4.15 a gallon on Friday, on average, up nearly 40 percent since the war began, according to AAA.

Over the past six months, “global prices of all main refined products have increased more than crude prices,” analysts at Goldman Sachs wrote in a research note.
