Econbrowser, an economics blog co-edited by economists James Hamilton of the University of California, San Diego, and Menzie Chinn of the University of Wisconsin–Madison, published a brief post on August 25, 2026, titled "Gasoline, Diesel, Kerosene: Diesel Rises Again," citing data from the U.S. Energy Information Administration (EIA). The post consists of an EIA attribution and an accompanying chart tracking movements in gasoline, diesel, and kerosene prices. As its headline indicates, the post reports that diesel prices have risen again (original post).

The U.S. Energy Information Administration is the statistical and analytical agency within the U.S. Department of Energy. It collects and publishes regular data on petroleum product prices, including weekly U.S. retail prices for gasoline and on-highway diesel. Those weekly series are widely used benchmarks for monitoring fuel costs in the United States.

The three fuels covered in the post are the largest refined petroleum products by demand in the United States. Gasoline is the primary fuel for passenger vehicles, diesel powers freight trucking, rail, and other heavy transport as well as farm and construction equipment, and kerosene-type jet fuel is the standard fuel for commercial aviation. Diesel and kerosene-type jet fuel are both middle distillates, a closely related family of refined products, while gasoline is a lighter product. All three are refined from crude oil, and their prices are tracked closely as indicators of both transportation costs and broader consumer price trends. Because diesel underpins freight movement, its price is watched as a gauge of shipping and logistics costs, one component of the delivered cost of goods.

The Econbrowser post follows the site's practice of sharing EIA data updates with minimal commentary, letting the charts convey the latest price movements across these key fuels. Readers who want to follow how the trend develops can watch the EIA's subsequent weekly price releases, which will show whether the increase in diesel prices continues in the weeks ahead.
