"Average gasoline prices fell in nearly every state over the last week, with diesel declining in all 50, pushing the national average to approximately $3.74 per gallon this July 4 — the third most expensive Independence Day on record, but well off the peak of $4.57 per gallon seen in May," said Patrick De Haan, head of petroleum analysis at GasBuddy. "GasBuddy is now tracking 41 states with average gasoline prices below $4 per gallon, while 37 states are seeing average diesel prices below $5. However, continued Ukrainian attacks on Russian refinery infrastructure have forced Russia to shift from fuel exporter to importer, tightening global supplies and putting upward pressure on crack spreads — explaining why pump prices haven't fallen as sharply as oil prices might suggest. Until the refining supply picture improves, significant further drops at the pump may be limited."
