Diesel prices have reached record levels in the US, significantly increasing the cost of keeping trucks that transport goods on the road.

Why it matters: The increase affects more than truckers and transportation companies. Higher distribution costs can be partially passed on through the prices of food and other products.

Diesel Prices in the US Hit Record: Truck Fill-Up Costs $641 More – Source: gasprices.aaa.com One day earlier, Patrick De Haan, head of petroleum analysis at GasBuddy, reported that the company’s live national average had reached $5.820 per gallon.

BREAKING: according to GasBuddy data, the live U.S. national average price of diesel has set a new record: $5.820/gal, surpassing the previous daily $5.819/gal all-time high that occurred June 17, 2022. (9/3/26 3:25pm ET)

That figure surpassed GasBuddy’s previous daily record of $5.819, set on June 17, 2022.

AAA reported an even higher average of $5.85 on September 4, compared with $5.7832 the previous day and $5.6105 one week earlier.

At last year’s price, the same amount of diesel would have cost approximately $1,113.63.

That represents a difference of approximately $641.37 per fill-up, although this is an illustrative calculation.

Not every trucker purchases 300 gallons at once or necessarily pays the average retail price. Some companies also negotiate fuel rates.

The pressure is even greater in California: AAA reports an average diesel price of $7.7094 per gallon, compared with $5.1381 last year.

The problem extends beyond transportation companies because trucks carry approximately 72.7% of domestic US freight tonnage, according to the American Trucking Associations (ATA).

Consequently, part of the increase can be incorporated into transportation costs and move through the distribution chain to businesses and consumers.

However, a 58% increase in diesel prices does not mean product prices will rise by the same percentage.

Fuel represents only one component of logistics costs, alongside wages, maintenance, insurance, and other expenses.

Nonetheless, the record strikes at the heart of the supply chain: The more expensive it becomes to transport goods, the greater the pressure on businesses and consumers.
