Gas crosses $4 a gallon in U.S. for the first time in 3 years

The ongoing war with Iran has driven gas prices above $4 per gallon for the first time since 2022, impacting American affordability and driving habits.

The price of a gallon of gasoline surged beyond $4 on Tuesday, crossing a significant psychological threshold for many Americans and highlighting the financial impact of the ongoing conflict with Iran.

As drivers face approximately a dollar increase per gallon compared to late February—when the U.S. and Israel initiated their military actions against Iran—the price of crude oil has experienced considerable volatility, fluctuating with varying sentiments regarding the war's duration.

Gasoline prices have spiked since the start of the war with Iran
Price per gallon, national average (as of March 31):

  • Regular unleaded: $4.02
  • Diesel: $3.76

Recent developments in the oil markets indicate growing anxiety that the Strait of Hormuz, a crucial global oil trading route, remains closed.

In a notable incident, Iran launched an attack that resulted in a substantial Kuwaiti oil tanker being set ablaze off the coast of Dubai. Reports of drone strikes in various Middle Eastern countries, including the United Arab Emirates and Saudi Arabia, further escalated tensions. As a result, crude oil was priced at approximately $102 per barrel on Monday, a stark increase from about $67 prior to the onset of the conflict.

The last instance of gasoline prices exceeding $4 per gallon occurred during the summer of 2022, prompted by Russia's invasion of Ukraine.

For many Americans, the reality of higher gas prices is unavoidable. Over the past weekend, Ron Purdin filled his car's tank after attending church, expressing his support for the current military action in Iran. Purdin made a stop at a Buc-ee's in Leeds, Alabama, where gas was roughly 50 cents below the national average but still exceeded typical prices in the Deep South. He experienced a bill of $43.09 to fill his vehicle, a $10 increase from a few weeks prior.

While he feels he can manage with these gas prices for approximately two months before experiencing significant strain, he hopes for a timely reduction. "I'm ready for it to go back down," Purdin stated. "When you're on a fixed income like I am, it makes it tough."

Despite the elevated prices, Americans nationwide continue to take to the roads. Data from Allstate Corporation's mobility analytics platform, Arity, shows that in mid-March, drivers logged increased mileage compared to the previous month.

Younger demographics, particularly Gen Z and millennial households, are particularly impacted by rising fuel costs, as they allocate a larger portion of their discretionary budgets toward gasoline, according to findings from the Bank of America Institute.
