“Average gasoline prices declined in 40 states over the last week as falling oil prices helped offset earlier price cycling in many markets, bringing relief to motorists after several states had already seen sharp increases,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Much of the decline came after renewed optimism surrounding a potential U.S.-Iran agreement pushed oil prices lower, easing geopolitical pressure on energy markets. In many states, that drop created breathing room after recent price cycles and allowed pump prices to fall again. While oil continued drifting lower over the weekend on hopes of a deal, new CENTCOM reports involving U.S. defensive strikes highlight how quickly the outlook could change. For now, motorists may continue to see some relief, but it remains too early to know how long the decline will last.”
