US Gas Price Map: States With the Biggest Hikes Since the Iran War Began

The Iran war may be unfolding thousands of miles away, yet its economic shock is hitting American drivers directly. Over the past month, petrol prices across the US have risen sharply, placing new pressure on households and businesses.

According to AAA data, the national average price of a gallon of petrol has jumped from $2.98 to about $4.02. That is a rise of roughly 35 per cent in just one month.

For millions of drivers, the impact is visible every time they pull into a petrol station. Filling a tank now costs far more than it did only weeks ago. The reason lies in global oil markets, where conflict in the Middle East has disrupted vital supply routes.

The Strait of Hormuz remains one of the most important shipping lanes for global oil. Reduced tanker traffic through the area has tightened supply and pushed prices higher worldwide.

While prices vary widely across the country, several states have seen particularly sharp increases.

States With the Biggest Gas Price Surges

Below are some of the states where drivers are feeling the most pain at the pump.

1. Utah: Utah has recorded the most dramatic increase in petrol prices. Over the past month, the average price has surged by more than 50 per cent. The state also saw the largest weekly jump, rising about 4.5 per cent.

2. Florida: Florida drivers have faced one of the steepest recent weekly increases. Prices there climbed around five per cent in just a week, reflecting the rapid spread of global oil price shocks.

3. Michigan: Michigan experienced the biggest weekly decline recently, falling more than 2 per cent. However, prices remain roughly 31 per cent higher than they were a month ago.

4. California: California continues to record the highest petrol prices in the country. Drivers there pay an average of $5.89 per gallon. That figure represents a monthly increase of nearly 27 per cent.

5. Washington: Washington also sits among the most expensive states, with average prices around $5.35 per gallon. Like California, local fuel standards and taxes contribute to the higher cost.

The Most Expensive States for Gas

While some states experienced the sharpest increases, others simply remain the most expensive places to buy petrol.

Here are the states currently charging the highest average prices.

1. California – about $5.89 per gallon
2. Hawaii – about $5.45
3. Washington – about $5.35
4. Oregon – about $4.93
5. Nevada – about $4.93

Western and Pacific states dominate this list. Higher environmental regulations and fuel taxes tend to push prices above the national average.

The Cheapest States for Drivers

Not every part of the US is paying the same price. Several states in the Midwest and Great Plains still enjoy relatively cheaper fuel.

Some of the lowest average petrol prices include:

1. Oklahoma – about $3.27 per gallon
2. Iowa – about $3.28
3. Kansas – about $3.29
4. Nebraska – about $3.37
5. South Dakota – about $3.40
6. Minnesota – about $3.42
7. North Dakota – about $3.43

Yet even in these states, prices remain significantly higher than they were just one month ago.

Political Debate Over Gas Taxes

Rising fuel costs have triggered a political response. Some state leaders are exploring ways to ease pressure on drivers.

Georgia has already suspended its state gas tax until mid-May. Governor Brian Kemp said the move aims to improve affordability during the price surge.

At the national level, lawmakers are also discussing relief measures. Senators Richard Blumenthal and Mark Kelly recently proposed suspending the federal petrol tax through October 2026.

Not all leaders believe the measure will have a major impact. Florida Governor Ron DeSantis has suggested that drivers may not notice much difference.

A Global Crisis Felt on Local Roads

The surge in petrol prices highlights how global conflicts can reshape everyday life. A war in the Middle East can quickly ripple through energy markets and reach drivers thousands of miles away.

For now, Americans continue to watch petrol station signs closely. As long as oil markets remain volatile, pressure on fuel prices is unlikely to ease.
