US Gasoline Prices Rebound Above $4 Per Gallon Amid Escalating Iran Conflict
REL_TIME: 21 Jul 2026 04:57Z · LANG: EN
The national average price for regular unleaded gasoline in the United States has climbed back above the $4 per gallon threshold as of Monday, July 20, 2026. This 13-cent weekly increase follows a period of relative stabilization and is directly attributed to renewed military hostilities between the U.S. and Iran. The conflict has disrupted global oil supply chains, particularly in the Strait of Hormuz, causing Brent crude prices to surge between $86 and $91 per barrel. The administration faces political pressure as rising fuel costs threaten to impact the upcoming November midterm elections.
// Background
The U.S.-Iran conflict, which escalated in late February 2026, has created a global energy crisis by threatening the Strait of Hormuz, a critical maritime chokepoint for approximately 20% of the world's oil supply. An interim peace agreement reached last month briefly lowered prices, but the collapse of this deal and renewed military engagement have reignited market fears and supply chain instability.
// Key Developments
- National average for regular gasoline reached $4.003 per gallon on Monday.
- Diesel prices have also risen, averaging approximately $5.11 per gallon.
- Brent crude oil prices have spiked from roughly $72 at the start of July to a range of $86-$91.
- The U.S. has engaged in 10 consecutive nights of airstrikes against Iran, leading to retaliatory attacks on U.S. allies.
- S&P Global Energy reports a 50% drop in vessel crossings through the Strait of Hormuz compared to the previous week.
