The U.S. diesel prices have surpassed $6 a gallon for the first time, adding pressure to households and businesses as the war with Iran pushes energy costs higher, according to CNN.
The national average reached $6.06, up eight cents in a week, according to AAA data cited in the report. Diesel prices have climbed more than 55% since the war began, outpacing gasoline.
Diesel is critical to trucking, freight rail, agriculture, construction and shipping. Higher fuel costs can therefore raise transportation expenses and ultimately increase prices for groceries and other consumer goods. Farmers could also face higher costs during harvest season.
Heating-oil users may see additional pain this winter. California diesel prices are already nearing $8 a gallon, while analysts warn the national average could approach $7.
CNN reported that higher diesel costs have already added more than $46 billion to U.S. expenses since the war began.
