U.S. diesel prices have surged dramatically, sparking fears that escalating costs will ripple through the economy — affecting groceries, shipping and construction — as the war in Iran stretches into its third week.
On Monday, the average price of a gallon of diesel reached $5 a gallon, marking the highest rate since December 2022 — the only other time it surpassed this worrying milestone, according to GasBuddy. On Tuesday, the average cost for a gallon of diesel stood at $5.04, up from $3.65 the previous month, according to AAA.
