"Average gasoline prices moved higher in the majority of states over the last week, with fewer than 10 states seeing declines, while diesel surged nearly 17 cents per gallon nationally, leaving it less than 25 cents away from an all-time record high," said Patrick De Haan, head of petroleum analysis at GasBuddy. "Gasoline, while not at all-time records, is at its highest level ever recorded this late in the calendar year, meaning Americans could for the first time ever see a national average price of gasoline above $4 per gallon on Labor Day — eclipsing the previous record of $3.83 per gallon set in 2012."
The national average price of gasoline has risen 2.9 cents per gallon in the last week, averaging $4.05/g today. The national average is down 5.0 cents per gallon from a month ago and stands 92.6 cents per gallon higher than a year ago, according to GasBuddy data compiled from more than 11 million weekly price reports covering over 150,000 gas stations across the country. The national average price of diesel has increased 16.6 cents compared to a week ago and stands at $5.584 per gallon.
"While some oil shipments are apparently getting through the Strait of Hormuz, the dominant force propping up both gasoline and diesel prices is increasingly the growing loss of Russian refinery capacity, as continued Ukrainian attacks knock more facilities offline and constrain the global supply of refined fuels," added De Haan. "Until that refining supply picture improves, both gasoline and diesel prices face continued upward pressure."
