US diesel prices reach record $6 per gallon
On September 11, 2026, US diesel prices hit a new all-time high of $6.05 per gallon, according to AAA data. This sharp increase follows global energy market disruptions caused by ongoing conflicts in the Middle East and other regions affecting oil supply chains. The war between the US, Israel, and Iran since late February has significantly impacted crude oil prices, with Brent (BZ=F) and WTI (CL=F) benchmarks rising over 20% in a month. Diesel demand remains high due to its critical role in transportation and heating systems across industries. Despite partial recovery of Gulf exports, refining capacity is constrained globally by strikes on infrastructure from Iran, Houthi militants, and Ukrainian drone attacks. Refineries worldwide are operating at near full capacity, limiting the ability to convert crude oil into usable products like diesel. Additional geopolitical tensions in Saudi Arabia’s Red Sea region and Black Sea export disruptions have further strained energy markets, raising concerns about inflationary pressures globally.
