Gas prices have risen significantly across the United States following the onset of the Iran war, with the impact varying widely by region, according to an NBC News analysis of AAA data [1]. The most dramatic increase was observed in Kenton County, northern Kentucky, where the average price for a gallon of gas reached $4.92, nearly double its pre-war level and representing a $2.32 per gallon increase [1]. In contrast, Fisher County, Texas, experienced a comparatively modest rise of just 60 cents per gallon as of May 5, 2026 [1].
State-level data reveals further disparities. Georgia saw the smallest average increase at $1.16 per gallon, while Ohio experienced the largest state-level jump, with prices up $2.06 per gallon [1]. On a national scale, most counties reported an average increase of $1.47 per gallon since the start of the conflict [1]. However, about 100 counties—primarily in Indiana and Ohio—faced increases of $2 or more per gallon, whereas just over a dozen counties, mainly in Georgia and Nebraska, saw increases of less than $1 per gallon [1].
Specific localities such as Millersburg in Dauphin County, Pennsylvania, saw gas prices rise by $1.40, closely aligning with the national average increase since the war began [1]. The data underscores the uneven impact of the Iran war on American consumers, with some regions bearing a much heavier burden than others [1].
The map and data referenced are updated daily, reflecting ongoing volatility and uncertainty in gas prices as the situation evolves [1].
CONCLUSION
The Iran war has led to a sharp and uneven increase in gas prices across the United States, with some counties experiencing price hikes of over $2 per gallon. The market impact is high, and continued volatility is expected as the conflict persists.
