U.S. diesel prices have climbed back toward levels last seen during the early months of the war with Iran, adding fresh pressure to transportation and business costs as disruptions in the Middle East and Russia squeeze global fuel supplies.
The nationwide average retail price reached $5.688 a gallon on Wednesday, just below the April peak that was the highest since mid-2022, according to AAA data. Separate Energy Information Administration data showed the average U.S. on-highway diesel price at $5.599 for the week ended Aug. 31, up from $5.313 five weeks earlier.
