“Gas prices continued to rise nationwide over the last week as seasonal factors, combined with ongoing supply concerns tied to the continued disruption in the Strait of Hormuz, pushed both gasoline and diesel prices sharply higher,” said Patrick De Haan, head of petroleum analysis at GasBuddy.
“It now appears increasingly likely that the national average price of gasoline will reach the $4-per-gallon mark—potentially as early as this week—for the first time since 2022, while diesel prices are surging to multi-year highs, with some markets nearing record territory. There are few signs of stabilization so far, as global oil prices continue to climb and early indications suggest consumers may begin to pull back in response to the rapid pace of increases.”
