The average price for diesel in the US has surpassed $6 for the first time, according to the American Automobile Association and fuel price monitoring app GasBuddy.
GasBuddy said on Thursday that a $0.15 rise over one week from $5.85 pushed the price to a record level, while AAA data seen on Friday showed a price of $6.0556 per gallon.
The milestone will be unwelcome news for the US government on the approach to mid-term elections as the impact of higher diesel prices more easily seep into every corner of the economy versus gasoline whose use is focused on passenger car transport.
"While gasoline gets the headlines, diesel is the fuel that moves the economy, powering the freight trucks, trains, agricultural equipment, and construction machinery behind nearly everything Americans buy," GasBuddy said.
"That means its impact reaches far beyond the transportation sector. As diesel climbs, higher supply chain costs work their way into the price of groceries, household goods, deliveries, and countless other products families rely on every day, even for households that never fuel a diesel vehicle."
AAA data shows the average price of a gallon of gasoline in the US is now $4.295, up from $3.1949, months before the start of the US-Iran war that would shutter the Strait of Hormuz, the conduit for about one fifth of the world's hydrocarbons supplies.
