"Average gasoline and diesel prices rose in nearly every state over the last week, as continued escalations between the U.S. and Iran, renewed Houthi attacks in the Red Sea, and fresh Ukrainian strikes on Russian oil refineries combined to keep upward pressure on both crude and refined product markets," said Patrick De Haan, head of petroleum analysis at GasBuddy.
"However, a weekend pullback in hostilities offered some relief, with oil prices opening sharply lower Sunday, suggesting the pace of increases at the pump may moderate in the days ahead. For now, motorists should expect prices to remain elevated, but the intensity of further gains will depend heavily on how the geopolitical situation develops in the coming week."
