When Farm States and Oil States Collide: What a Diesel Export Ban Really Costs

What Happened

Senate Republicans are divided over a proposal from Sen. Chuck Grassley of Iowa and other farm-state senators: an embargo on diesel exports intended to increase domestic supply and lower prices at the pump. Senate Majority Leader John Thune of South Dakota has said he's open to considering it, though backing from oil-state Republicans remains uncertain, according to The Hill.

The proposal echoes the 1970s energy crisis, when the U.S. last imposed such an embargo. That history matters because export bans carry consequences that extend well beyond their stated purpose.

What It Means for You

The pitch sounds straightforward: farmers pay high diesel prices, exports get banned, more diesel stays home, prices fall, farm costs drop.

Trade doesn't work that way.

When the U.S. bans exports, trading partners typically retaliate by restricting American imports. For farm states, the impact is severe. American agricultural exports reached $177 billion in 2024, making farming one of the nation's largest export sectors. Farmers rely on global markets, wheat to Asia, beef to South Korea, corn products worldwide. A diesel embargo would give foreign governments reason to block those sales in response.

This is significant because American agriculture already operates under strain. The U.S. produces more food than it consumes on more arable land than any other country, yet 47.9 million Americans live in food-insecure households. That's a policy outcome, not an accident. When export markets close, farms lose the revenue that keeps them operating, which eventually means fewer farms, higher food prices domestically, and more pressure on food security.

Oil-state Republicans raise a real point: an export ban affects energy markets well beyond U.S. borders. Europe depends heavily on refined petroleum products. If the U.S. cuts exports, other countries search for supply elsewhere, often at higher cost. That instability eventually affects global energy prices, including what Americans pay.

The Bigger Picture

Trade has generated $2.6 trillion in economic gains for America while displacing 2.4 million jobs in communities that never rebuilt. That fact shapes every trade conversation, and rightfully so. The solution, though, isn't to swing from free trade to protectionism. It's to establish fair rules and enforce them, rather than erect barriers that damage the people you're trying to help.

The 1970s offer a cautionary example. When the Nixon administration banned soybean exports in 1973 to control domestic prices, farmers initially saw their prices rise. But the move damaged trust with trading partners and triggered retaliatory restrictions that hurt U.S. agricultural exports for years afterward. The real culprit, inflation from oil shocks and monetary policy, remained untouched.

A diesel export ban would treat the symptom. Diesel prices are high because global demand is strong, refining capacity is constrained, and geopolitical disruption roils energy markets. A ban might modestly reduce domestic prices but won't address the global forces driving energy costs. It will, however, invite retaliation against American exports, agriculture, manufacturing, technology. The damage spreads across workers and communities broadly.

The underlying issue is affordability. Productivity has risen 92.4% since 1979 while wages rose only 33.6%. Diesel crushes farmers not because they lack competitiveness, but because their income hasn't kept pace with costs. Truck drivers, construction workers, and small businesses running on fuel face the same squeeze. An export ban says, "We'll protect your market by closing it," instead of addressing the wage-to-cost gap that's the actual problem.

Where This Goes

The Common Good Party's stance on trade is straightforward: trade can serve working people, but only under rules that are genuinely fair and enforced. That means confronting monopolies that restrict competition, holding companies accountable when they export jobs without consequence, and ensuring trade agreements include real labor and environmental standards.

A diesel embargo doesn't accomplish any of this. It's a quick fix dressed as protection for one group that creates problems for another. It won't sustain lower prices. It will provoke retaliation. And it will worsen the affordability crisis for the communities it claims to aid.

The actual path forward requires more effort: bringing farm income into line with farm costs through fair commodity pricing and supply management; investing in refining capacity and clean energy to diversify fuel supply; and writing trade rules that don't just protect existing players but give workers and small businesses real power. That's not ideological. That's empirical. And it's the only approach that doesn't sacrifice one group's future for another's temporary relief.
