“Average gasoline prices have jumped for a second straight week as oil prices have climbed back above the $60-per-barrel mark amid ongoing geopolitical tensions,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “New sanctions on Iran’s oil are making it more difficult for those barrels to reach the market, tightening supply, while the major winter storm that sent temperatures plunging is also likely to impact refineries, causing disruptions and reduced output. Diesel prices have jumped as colder weather boosts demand for heating oil, a combination that could keep both gasoline and diesel prices moving higher in the week ahead.”
