Diesel did it again.
The national average price of diesel set yet another weekly record for the week of September 21, reaching $6.529 a gallon — the fourth record-setting week in a single month, according to the trade outlet Logistics Management, which tracks the Energy Information Administration's weekly benchmark. The outlet reported the new high topped the prior week's $6.285 and the early-September reading.
The numbers converge across independent trackers. The EIA's own analysis reported the retail diesel average at $6.29 as of Monday, September 14 — the highest price since 2022 on an inflation-adjusted basis. AAA's daily average, cited by NPR on September 21, had climbed above $6.51, breaking the previous record of about $5.85. FreightWaves, reporting the same DOE/EIA series, called it the highest in that series' history and noted AAA's daily average had also set a new all-time high.
This is a breaking story in the sense that matters: fuel is the connective tissue of the American economy. Diesel prices flow directly into the cost of moving groceries, building materials, farm harvests, and packages — which means a record diesel price is a preview of a record grocery receipt.
What we're still watching: whether refiners and export flows bring relief, and whether the export restrictions reportedly under consideration change the math. We'll update this story as the weekly benchmark moves.
