“In just a week, consumers have seen gasoline prices surge at one of the fastest rates in years after oil prices spiked following U.S. strikes on Iran and the effective closure of the Strait of Hormuz,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “With additional attacks across the Middle East over the weekend pushing oil above $100 per barrel for the first time in years, fuel markets are now rapidly recalibrating to the risk of prolonged disruption to global supply flows. As a result, gasoline prices in many states could climb another 20 to 50 cents per gallon this week.”
