What happened
A fuel-price information service released data on September 4 showing that the national average retail diesel price on September 3 reached $5.848 per gallon, setting a new all-time high.
That price exceeded the previous record of $5.819 per gallon set on June 17, 2022. A year earlier, the national average was just $3.7 per gallon.
The company noted that diesel, which powers freight trucks, trains, agricultural equipment, and construction machinery, has a broader impact on inflation and business costs than gasoline. Higher diesel prices push up transportation expenses and often lead to increases in the cost of consumer goods and services.
Why it matters
Diesel fuels much of the economy that moves goods and performs essential work, so a record price means cost pressures are spreading well beyond the fuel pump.
According to the company's oil analysis director, higher diesel prices affect more than the transportation sector. Supply chain cost increases can push up prices for groceries, household items, and delivery services, squeezing consumers.
