Global diesel prices hit record highs, further rises possible
War-related refinery damage, export bans and Red Sea disruptions have tightened supplies, with U.S. diesel averaging $6.505 a gallon, AAA said.
- On Monday, September 21, 2026, U.S. retail diesel prices reached a record average of $6.505 per gallon, surging past $6 in most states as geopolitical tensions strained global supply chains.
- Global diesel shortages stem from the ongoing U.S.-Iran war, which disrupted shipments through the Strait of Hormuz, combined with Ukrainian drone strikes damaging Russian refineries and Moscow extending export bans.
- Record fuel costs are severely squeezing profit margins for truckers and farmers, with long-haul drivers facing fill-up costs ranging from $1,200 to over $1,900 per trip, according to industry data.
- Higher diesel prices are cascading through supply chains, with retailers absorbing freight cost increases that could eventually raise prices for consumers on produce, dairy, and meat products this fall.
- Experts warn heating oil costs could rise by more than 30 percent this winter as the U.S. enters the season with distillate inventories 15 percent below the five-year average.
