  • Oil and gas prices across the US have surged amid the ongoing US-Israeli war with Iran.
  • Gas prices have been spiking nationwide, with a gallon approaching or exceeding $4 in 30 states.
  • Utah has seen the largest rise in gas prices over the past month, up 52.4%.

Americans are feeling the effects of the ongoing war in Iran at the gas pump.

Since the conflict started at the end of February, gas prices have been rising across the US, with a gallon of gas surpassing $3 in all 50 states for the first time since 2023. A dozen states have surpassed $4, with 19 others closely approaching at $3.75 or above. In California, the most expensive state for gas right now, regular gas costs an average of $5.88 per gallon.

The war, which has been ongoing after the US and Israel launched a joint military operation against Iran on February 28, has sent global oil markets soaring. It has significantly disrupted passage through the Strait of Hormuz, a critical shipping artery through which roughly 20% of global oil and liquefied natural gas travel regularly.

On average, gas prices across all US states have risen by 33.38% over the past month, according to AAA's Fuel Price Tracker. In many states, gas prices are a full dollar higher than they were a month ago. (Gas prices typically vary between states due to factors such as local taxes, proximity to supply, and operating costs.)

We looked at the gas prices reported by AAA on March 30 and compared them with prices reported a month ago. We calculated the percentage increase for each state to determine where prices are rising the most.

In these 20 states, price increases are rapidly outpacing the national average.
