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.

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.

The war 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 31.03% in the past month, according to data from AAA's Fuel Price Tracker.

In multiple states, gas prices are a full dollar higher than they were a month ago.
