U.S. gasoline prices surged sharply amid escalating tensions involving Iran, with the national average reaching $3.48 per gallon and crude oil briefly surpassing $100 per barrel due to disruptions in the Strait of Hormuz. Analysts warn that fuel costs may remain high through the summer because of ongoing supply uncertainties and increased demand, despite some recent price volatility. International markets reacted with significant fluctuations, and major industrialized nations are considering coordinated measures to stabilize energy supplies amid concerns over further production cuts and transit challenges.
