“Average gasoline prices surged for many Americans through the first half of last week before easing in some areas after oil prices slipped following President Trump’s announcement of a ceasefire,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “However, with a breakdown in talks and renewed escalation over the weekend, motorists should prepare for another round of price increases. The move toward a full blockade of the Strait of Hormuz is compounding global supply concerns and risks further disrupting flows, which pushed oil prices sharply higher in Sunday night trading. As a result, gasoline prices are likely to jump again this week, with diesel expected to follow, until there is a meaningful restoration of shipping through the Strait.”
