“Average gasoline prices fell in 46 states over the last week, with diesel declining in 49, pushing the national average to its lowest level since mid-March,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “The declines came despite a turbulent week, as fresh attacks were traded between the U.S. and Iran before both sides agreed to halt hostilities just in time Sunday, preventing what could have been a significant spike in oil prices. For now, GasBuddy anticipates the national average will continue drifting lower this week, though the situation remains anything but predictable. A handful of price-cycling states could see prices jump ahead of the July 4 holiday, while many states that already cycled higher last week should see prices fall back down. Motorists in non-cycling states are likely to see continued relief, but the fragile nature of the U.S.-Iran situation means the outlook could shift quickly.”
