US national average diesel prices reached $6 per gallon for the first time in history on Thursday, GasBuddy said in a statement, as Middle East tensions and tightening global supplies continue to push fuel costs higher.
The American Automobile Association's national diesel average reached $5.9773/gal Thursday, nearing the $6/gal mark, according to the AAA website.
GasBuddy said its real-time data captured the $6/gal milestone first, adding that it comes less than a week after prices set a fresh all-time record of $5.85.
"It is a level diesel has never reached...," according to GasBuddy's statement.
Diesel prices are now up roughly $2.30/gal from a year earlier, when the national average stood near $3.70/gal, according to GasBuddy.
"Not every day are new all-time records set, and this will be a particularly painful one for the economy that may not even be immediately felt, but record diesel prices will impact every cargo, shipment, every delivery Americans are taking, and are likely to reignite inflation up and down the supply chain," said Patrick De Haan, head of petroleum analysis at GasBuddy.
He warned of a costlier holiday season, with diesel prices set to continue their rally as geopolitical tensions persist.
The milestone comes weeks after diesel futures first crossed the $5/gal threshold, as Strait of Hormuz product exports remained below pre-war levels and Russia's export ban tightened global supplies, according to a Bloomberg report earlier on Thursday.
