GOP Urges Trump To Make Major Diesel Move
Sen. Chuck Grassley is calling on President Donald Trump to consider restricting U.S. diesel exports as soaring fuel prices create new financial pressure for American farmers, truckers and businesses.
The Iowa Republican raised the issue over the weekend as diesel prices climbed to record levels nationwide.
Grassley argued that keeping more diesel inside the United States could help domestic farmers and transportation companies struggling with dramatically higher operating costs.
His proposal comes as energy prices have become an increasingly important economic issue for rural America.
Diesel Prices Reach Record High
AAA reported that the national average price for diesel reached approximately $6.51 per gallon on September 20, 2026.
That compares with about $3.70 per gallon one year earlier.
Diesel prices have also risen rapidly in recent weeks. The national average stood near $6.20 one week earlier and approximately $5.55 one month earlier, according to AAA.
For farmers, trucking companies and other businesses that use large amounts of diesel every day, an increase of that size can translate into substantial additional expenses.
The situation is especially serious in Iowa.
AAA reported an average diesel price of roughly $6.29 per gallon in Iowa on September 20, compared with about $3.54 one year earlier.
AAA’s data showed that the September 20 price was the highest recorded statewide diesel average in Iowa.
Grassley Calls For Diesel Export Restrictions
Grassley questioned why the federal government could not temporarily restrict diesel exports in response to high domestic prices.
In a social media post Saturday, Grassley compared the idea with export restrictions used by previous administrations when domestic commodity prices became a major concern.
“High diesel prices ARE KILLING FARMERS INCOME,” Grassley wrote.
He returned to the issue Sunday, arguing that Washington should put American farmers and truckers in a stronger position during a period of international instability.
Grassley’s argument centers on a straightforward question: Should the United States continue exporting diesel at current levels while domestic consumers are paying historically high prices?
Any decision to restrict exports would involve trade-offs.
Supporters could argue that retaining additional fuel for domestic consumption may increase supply available to U.S. customers.
Opponents could argue that export restrictions could disrupt refining markets, international trade relationships and future energy investment.
Why Diesel Prices Matter To American Farmers
Diesel is one of the most important fuels in American agriculture.
Farmers rely on it to operate tractors, combines and other heavy equipment. Diesel also powers many of the trucks that move crops, livestock, fertilizer and agricultural supplies across the country.
That makes rising diesel prices particularly important for farm income.
A farmer using thousands of gallons of fuel during planting or harvest season can face sharply higher expenses when prices increase by several dollars per gallon.
Those expenses come on top of other costs involving seed, fertilizer, equipment, labor, insurance and transportation.
For family farms operating on narrow margins, fuel prices can therefore have an immediate effect on profitability.
Trucking Industry Also Faces Higher Costs
Farmers are not the only Americans affected.
The trucking industry depends heavily on diesel to transport consumer goods, food, construction materials and industrial products across the country.
Higher diesel prices increase the cost of moving those products.
Businesses may absorb some of those expenses, but transportation costs can also eventually affect prices throughout the supply chain.
That means diesel prices can have consequences for consumers who never personally purchase diesel fuel.
Global Oil Markets Add Pressure
International instability has contributed to volatility in energy markets.
AAA said earlier in September that continued uncertainty surrounding the Strait of Hormuz had pushed crude oil prices higher.
The Strait of Hormuz is one of the world’s most important oil-shipping routes, making disruptions in the region capable of influencing global crude prices.
Higher crude oil prices can eventually translate into higher prices for diesel, gasoline and other petroleum products.
Domestic refining capacity, inventories, transportation infrastructure and regional supply conditions can also influence what Americans ultimately pay at the pump.
Energy Costs Become A Bigger Economic Issue
The rapid increase in diesel prices is drawing attention because transportation and agriculture touch nearly every part of the U.S. economy.
Diesel does more than power trucks and farm machinery.
It is used in construction equipment, freight transportation, manufacturing operations and other industries responsible for moving goods throughout the country.
When fuel expenses rise substantially, those costs can spread through the economy.
For Americans living in rural communities, the consequences can be especially noticeable because driving distances are often longer and agriculture plays a larger role in the local economy.
Grassley Wants Washington To Act
Grassley’s proposed diesel export restriction would represent a significant change in federal energy policy.
His comments nevertheless reflect growing concern about the economic burden facing farmers and truckers as fuel prices remain near historic highs.
The Trump administration would have to determine whether restricting exports could meaningfully increase domestic diesel supplies while considering possible consequences for refiners, international markets and U.S. trading partners.
For farmers, however, the immediate concern is much simpler.
Every additional dollar spent on diesel is money that cannot be used elsewhere on the farm.
With the national diesel average above $6.50 per gallon and Iowa prices at record levels, pressure is building for policymakers to address the cost of keeping America’s farms, trucks and supply chains moving.
