Iran war: US gasoline prices surge as conflict escalates
The national average price of gasoline in the US has hit $4 a gallon for the first time since 2022 amid rising tensions in Iran.
Summary
As of March 31, 2026, the national average price of gasoline in the United States has surged to $4 per gallon, marking a significant increase attributed to geopolitical tensions in Iran.
The escalation of conflict in the region has implications for global oil supply chains, particularly with Iran's recent decision to implement fees for vessels transiting the Strait of Hormuz.
This development could affect shipping costs and overall throughput in oil transport, potentially leading to further fluctuations in gasoline prices across the US market.
