The impact of the war between America and Iran is being felt all over the world. America itself has not remained untouched by its consequences. According to the latest data for May 2026, gasoline prices in America have increased by 50 percent.
According to the American Automobile Association (AAA), the average price of regular gasoline in the US has increased from $4.48 to $4.51 per gallon. In the past week alone, prices have increased 31 cents per gallon. Before the outbreak of war in Iran in late February 2026, prices were around $2.96; Now they have increased by more than 53 percent.
Where are prices highest?
The average price in California has reached $6.17 per gallon.
Prices in Washington and Hawaii have reached $5.76 and $5.66 per gallon, respectively.
Where are prices lowest?
Prices remain comparatively low in states like Oklahoma, Kansas and Georgia. Prices here range from $3.70 to $3.89 per gallon.
Why are gasoline prices rising so fast in the US?
Global oil markets have been in turmoil since the war with Iran began on February 28. Iran’s blockade of the Strait of Hormuz has cut the world’s oil supply by 20 percent. As a result, crude oil prices in international markets have increased to a range of $100 to $112 per barrel. Since crude oil prices account for about 51 percent of the retail price of gasoline, prices at the pump are rising. As prices continue to rise, the budgets of low-income families in America are being strained. According to a report, many families are now spending about 10 percent of their income on fuel. The situation has reached such a stage that about 44 percent of people in America have reduced driving.
