GasBuddy: Fuel Prices Remain Higher, Volatile Due to Geopolitical Conflicts07/27/2026Average gas and diesel prices rose over the last week. GasBuddy's Head of Petroleum Analysis Patrick De Haan explains:"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. 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."GasBuddy says the national average price of gasoline has risen 10.8 cents per gallon in the last week, averaging $4.06 per gallon Monday, July 27th.
