The national average diesel price dropped 16.5 cents this week to $6.127 per gallon, the largest weekly decline since the Iran war began. Brent crude fell 2.2% to $90.55 per barrel, its lowest level in three months.
Why it matters
Oil prices declined after President Donald Trump said the war in Iran is militarily effectively over. Lower crude costs are feeding through to fuel prices for trucking and businesses across the United States.
The national diesel average fell from $6.292 to $6.127 per gallon this week, with the Rocky Mountain Region dropping nearly 24 cents to $6.206 and the Midwest Region falling just over 20 cents to $6.201. The source does not indicate whether these regional declines will hold as crude prices shift.
The details
Diesel prices fell as oil prices began to drop, with Brent crude down 2.2% and the U.S. benchmark down 1.8% in the same period. The weekly decline was the largest national diesel drop since the Iran war began.
Timeline
One week before the price declines, American voters handed control of both chambers of Congress to Democrats in midterm elections.
This week, the national average diesel price fell 16.5 cents.
Market Landscape
This week's 16.5 cent weekly diesel drop is the largest since the Iran war began, a sharp break from the price pressure that accompanied the conflict. The decline tracks Brent crude's move to its lowest level in three months.
Lower diesel prices reduce fuel costs for truckers and businesses that rely on diesel for transport. Households may see the effect indirectly through freight and delivery costs over time.
The takeaway
Diesel price swings track crude oil closely, so fuel costs can change quickly when oil markets move. Businesses that depend on diesel may want to watch crude benchmarks for early signs of where pump prices are heading.
