The price of diesel has shot up across the country amid a supply crunch which is raising concerns among analysts that a severe, continued shortage might cripple the U.S. economy this winter and send already high inflation soaring.
According to data from the American Automobile Association (AAA), diesel prices reached a national average of $5.309 per gallon as of today, compared to $3.634 a year ago. Prices are now higher than a month ago, when diesel cost $4.876, but lower than a week ago when they shot up to $5.326.
Diesel reached a record-high average price of $5.703 a gallon in June this year, and even as prices have cooled a little since then, the decrease hasn't been nearly as significant as the drop in gas prices. Where gas prices have dropped by 24 percent since June, diesel prices have gone down by only 8 percent.

Patrick De Haan, GasBuddy's head of petroleum analysis, previously told Newsweek that diesel prices remain high "due to inventories at very low levels and limited ability to quickly improve supply," at the same time as demand is at an all-time high in the aftermath of the pandemic.
These are the 10 states where diesel prices have jumped the most on a year-on-year, month-on-month, and week-on-week basis, according to AAA data.
