GasBuddy: Potential U.S-Iran Deal Good News for Gas Prices06/15/2026A potential deal between the U.S. and Iran could soon bring prices at the pump lower. GasBuddy's Head of Petroleum Analysis Patrick De Haan explains:"Average gasoline prices fell in 47 states over the last week, with the national average dropping below $4 per gallon late Sunday for the first time since mid-April. The decline came as oil prices moved sharply lower in reaction to news of a potential deal between the United States and Iran, though it remains to be seen whether the agreement will hold. A handful of price-cycling states saw averages jump before joining the broader downward trend. The real test now shifts to the Strait of Hormuz, where any reopening and resumption of normal oil flows would be the clearest signal that this relief is durable. For now, the national average could continue falling, provided there isn't a drastic reversal and the U.S. and Iran continue moving in a positive direction." -Patrick De HaanIn Fort Wayne, average gasoline prices have fallen 14.5 cents per gallon over the last week, averaging $3.22 per gallon Monday. In Toledol, average gasoline prices have dropped 11 cents per gallon, averaging $3.91 per gallon Monday.
