Patrick De Haan, head of petroleum analysis at GasBuddy, said, “Average gasoline prices rose in virtually every state over the last week, with 45 states seeing increases of more than 3 cents per gallon, led by the Great Lakes region where refinery issues sent Michigan, Indiana, Illinois, Ohio, and Wisconsin all up more than 30 cents per gallon.” He added, “Diesel rose in every state, with five states seeing increases exceeding 50 cents per gallon, as continued strikes on Russian oil refineries tighten global diesel supply- a pressure further amplified in the Great Lakes by regional refinery issues. Any broader directional change will depend heavily on overseas developments, and with new Houthi attacks and fresh U.S.-Iran escalations, the outlook remains deeply uncertain.”
