Who Pays for High Diesel Prices? How Record-High Prices Could Affect Consumers
U.S. diesel prices have climbed to record highs, increasing costs for trucking companies, farmers, and other businesses that rely on the fuel.
For consumers, the impact may be less obvious. Most drivers do not fill their cars with diesel, but diesel powers much of the system that moves goods through the U.S. economy. Higher fuel costs can therefore show up indirectly in the prices consumers pay for groceries, packages, construction materials, and other everyday goods.
The national average price of diesel crossed $6 per gallon for the first time in September before climbing to about $6.31, according to reports from Bloomberg and CNBC. In California, prices moved above $8 per gallon.
Several factors are contributing to the increase. Fighting in the Middle East has disrupted refining and shipping through the Strait of Hormuz, a major route for global energy supplies. The U.S.-Iran conflict has also raised concerns that elevated energy prices could persist if the war continues.
At the same time, global diesel supplies have tightened because of disruptions in Russia. Ukrainian drone strikes have targeted Russian energy infrastructure, while Russia has also restricted diesel exports. Those supply pressures are colliding with higher seasonal demand heading into the fall.
The result is a sharp increase in the cost of moving goods. Diesel powers long-haul trucks, farm equipment, freight transportation and heavy machinery. A higher diesel price can therefore affect a product at several stages before it reaches a consumer.
Food is one example. Farmers may use diesel-powered equipment to grow and harvest crops. Agricultural products then have to be transported to processors, warehouses, and retailers. Each step can involve additional fuel costs.
The same is true for consumer products shipped by truck. Businesses may absorb some of those higher expenses, but sustained increases in transportation costs can also be passed along through higher prices.
Transportation companies are already reporting pressure.J.B. Hunt said it expected earnings to fall between 5% and 10% from the second quarter to the third quarter because of higher costs, according to CNBC. Independent truckers may be even more exposed because they have fewer resources to absorb a prolonged increase in fuel prices.
The Owner-Operator Independent Drivers Association has warned that persistently high diesel prices could force some drivers out of business. The Trump administration has attempted to provide relief by expanding the use of red-dyed diesel on highways and directing the Treasury Department to consider deferring the 24.4-cent federal diesel tax through the end of the year.
Trucking groups have questioned how much that will help. The American Trucking Associations has argued that the policy does not increase the overall supply of diesel or address the shortage that pushed prices higher. State restrictions on dyed diesel could also complicate its use for interstate carriers.
Cutting a tax can reduce the price paid at the pump, but it does not necessarily resolve the supply problems behind the increase. Diesel prices matter far beyond truck stops. Companies can absorb some higher costs, reduce spending elsewhere or improve efficiency rather than immediately raising prices. But the longer diesel remains elevated, the greater the pressure on businesses that depend heavily on transportation. Consumers may never see a separate diesel surcharge on a grocery receipt or online order. Instead, higher fuel costs can become one more expense built into the final price of the goods they buy.
