Overview
Updated 1 hour agoUS diesel prices hit a record $5.85 a gallon on September 4, topping the previous peak of $5.81 set in June 2022. The national average has climbed about 55 percent since the US and Israel launched their war against Iran on February 28, when diesel cost $3.76.
Two conflicts are cutting global supply. Iranian attacks on tankers slow traffic through the Strait of Hormuz, and Ukrainian drone strikes on Russian refineries pushed Moscow to ban diesel exports through September 30. Together the disruptions have removed about 8 percent of world diesel supply, according to analyst Andy Lipow.
Why it matters
Every dollar per gallon of diesel shows up as higher food and shipping costs for households.

Historical Context
3 moments from history that rhyme with this story — and how they unfolded.
1973 OPEC oil embargo
Arab members of OPEC cut oil exports to the US and allies in response to US support for Israel in the Yom Kippur War. Oil prices roughly quadrupled, US gas stations ran short, and long lines formed at pumps.
The embargo ended in March 1974 after diplomatic efforts. Prices stayed high for years.
Triggered lasting policy shifts: fuel economy standards, the Strategic Petroleum Reserve, and the 55 mph speed limit.
The clearest historical example of Middle East conflict driving US fuel prices and broader inflation.
2008 oil price spike
Crude futures climbed to $147 a barrel in July 2008 as global demand outpaced supply. US gasoline topped $4 a gallon nationally for the first time. Consumers cut back on driving and discretionary spending.
Prices collapsed as the financial crisis triggered a deep recession later that year.
Demonstrated how sustained high fuel costs act as a drag on consumer spending and can help tip the economy into downturn.
Shows the path from sustained high diesel prices to a broader economic slowdown, a risk analysts now flag.
Russia's invasion of Ukraine and the June 2022 diesel record
Russia invaded Ukraine in February 2022, disrupting energy markets. Crude spiked and diesel hit $5.81 a gallon in June 2022, the record at the time. Refiners struggled to replace Russian diesel exports while Europe scrambled for alternative supplies.
Prices eased by late 2022 as recession fears cut demand and Russia kept exporting at a discount.
Set the benchmark that this event just broke, and showed how quickly war-driven supply shocks move fuel prices.
The current record breaks the 2022 peak under similar conditions: war cutting crude supply and refining capacity.
