“Average gasoline and diesel prices rose in nearly every state for the second straight week, with the national average price of gasoline likely to reach $4 per gallon within the next 48 hours and diesel already back above $5 per gallon nationally,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “While the ongoing U.S.-Iran situation continues to weigh on markets, the story is increasingly less about crude oil and more about global refining capacity — the Strait of Hormuz remains closed while continued Ukrainian attacks on Russian refineries further squeeze an already strained supply picture. With WTI crude approaching $85 per barrel in Sunday night trading, price-cycling markets are likely to see another jolt higher in the coming days, and motorists should brace for a rougher stretch ahead.”
