Diesel Tops $6.53 a Gallon; Distillate Stocks Fall

U.S. on-highway diesel rose to a nominal record of $6.529 a gallon on Sept. 21, the Energy Information Administration reported on Sept. 23. Distillate stocks fell to 107.431 million barrels in the week ended Sept. 18.

Retail diesel climbed 24.4 cents in the week to Sept. 21. The EIA attributed the price increase to tight global distillate supplies and higher crude prices.

Distillates, which include diesel, are a primary fuel for road and rail freight. Lower inventories and higher pump prices can increase shipping costs for carriers.

Federal data showed related upstream pressure before the retail record. The Bureau of Labor Statistics recorded a 24.1% month-over-month jump in diesel fuel producer prices in August and a 2.0% rise in the truck freight transportation price index for August.

How much of the higher fuel cost reaches consumers depends on contract terms, competition among carriers and how long the supply tightness lasts. Persistent increases across billing cycles are more likely to be passed on than a short-lived spike.

Policymakers and market participants will assess upcoming price data for signs of pass-through. The Labor Department will publish the September consumer price index on Oct. 14 and producer prices on Oct. 15. The Bureau of Economic Analysis will release September personal income and outlays, including the PCE price index, on Oct. 29. The most recent CPI reading covered August and showed a 0.4% increase from July.

The Federal Reserve raised its target range for the federal funds rate to 3.75%–4% on Sept. 16, citing elevated inflation. If fuel- and freight-driven inflation keeps price growth firm, market expectations about how long rates remain elevated could be affected, which influences assets sensitive to financing conditions.

EIA and BLS data through late September point to tighter distillate supplies and upstream price increases. The upcoming official reports will provide additional information on whether those pressures are appearing in broader consumer prices.
