U.S. Gas Prices Surge Above $4 Amid Iran Conflict and Market Pressures
The national average price for a gallon of regular gasoline in the United States has risen to $4.0030 as of July 20, 2026, according to AAA data. This increase is attributed to higher oil costs and market pressures, exacerbated by renewed hostilities in the Middle East and the effective closure of the Strait of Hormuz. The average price has increased by approximately 13 cents over the past week. The conflict between the U.S. and Iran has led to significant disruptions in oil supply, particularly affecting the West Coast, which relies heavily on Middle Eastern imports. President Trump has urged gas retailers to lower their prices and has announced that the Department of Justice will investigate alleged price gouging by U.S. oil majors, although industry representatives deny these allegations.
