Rising Diesel Costs Hit Consumers: The Downstream Impact Explained

Rising diesel prices are increasing transportation costs across the supply chain, adding pressure to freight carriers, farmers, manufacturers, retailers and consumers. Industry analysts say elevated fuel expenses could continue even if crude oil prices ease, as limited inventories and refinery constraints keep pressure on diesel markets.

Diesel costs continue to climb

Diesel prices cited in recent market reports were nearly 75% higher than a year earlier, while regular gasoline prices were approximately 40% higher. In parts of the Great Lakes region, refinery disruptions contributed to sharp increases. Reported gasoline prices reached about $4.77 per gallon in Michigan and $4.37 in Ohio, while diesel prices in some areas reached approximately $6.32 per gallon.

Andy Dyer, CEO of AFS Logistics, said low inventories and refineries operating near capacity could keep transportation costs elevated for the foreseeable future. He noted that even a decline in crude oil prices may not immediately translate into lower diesel costs.

Freight and supply-chain impacts

Diesel is a primary fuel for long-haul trucking, regional freight operations and last-mile delivery. As fuel prices rise, carriers face higher operating expenses that are often reflected in fuel surcharges and freight rates.

Those additional costs can move through multiple stages of the supply chain before reaching consumers through higher prices for groceries and other goods. Rob Thummel, senior portfolio manager at Tortoise Capital, said diesel remains critical to the delivery of consumer products and that its price affects businesses and households across the economy.

Higher diesel costs also affect agriculture, mining, manufacturing and construction, industries that rely heavily on fuel-powered equipment and transportation. Farmers in the United States have reported increased expenses as diesel prices remain more than 70% above year-ago levels in some comparisons.

Consumers and businesses adjust

Businesses with limited alternatives to diesel-powered equipment must either absorb the added expense or pass it along through higher prices. Consumers who operate diesel-powered vehicles are also facing the increase directly at the pump.

Some motorists have reduced nonessential travel or turned to alternative transportation as gasoline prices rise. Analysts have warned that sustained fuel inflation could contribute to one of the most expensive holiday shopping and travel seasons on record, depending on how diesel and gasoline markets develop.

Ongoing refinery problems, supply-chain constraints, geopolitical instability and broader energy-market fluctuations are expected to remain important factors influencing fuel prices and transportation costs.
