US gasoline prices hit their highest level in four years on Tuesday, averaging $4.17–$4.23 per gallon, driven by the ongoing Iran war and stalled negotiations over reopening the Strait of Hormuz. The price surge is directly tied to global oil market disruption — the same geopolitical tensions freezing peace talks are keeping crude supplies tight and prices elevated. The broader economic impact is significant: a family spending $60 per week on gas is paying roughly $3,000 more annually compared to pre-war prices.
