Corn Belt cost surge crisis

Highlights

Fertilizer 11-52-0 now costs over $900 per ton, up from $470 a decade ago, deepening Corn Belt farmers' financial distress as Iran conflict drives up input costs.
Farmers growing nine principal crops face projected losses of $31 billion in 2024 and $32 billion in 2027, with corn losses at $131 per acre this year.
U.S. diesel prices surge to $5.45 per gallon from $3.81 pre-war, raising production costs, while December corn futures jump 10 percent to $5.15 a bushel amid weather and supply concerns.

Rising fuel and fertilizer costs squeeze farm budgets

As reported by Financial Times, farmers across the Corn Belt say the spike in diesel and crop nutrient prices since the U.S. attack on Iran in February is worsening an already fragile financial position for grain producers.

Matt Bailey, who grows corn and soybeans in eastern Nebraska, says key planting fertilizer 11-52-0 now costs more than $900 a ton, up from $470 a ton 10 years ago. John Hansen, president of Nebraska Farmers Union, calls it the worst financial downturn in the sector since the 1980s.

A recent study by the American Farm Bureau Federation finds that, without government assistance, farmers growing nine principal crops, including corn, lose $31 billion this year and $32 billion in 2027. Faith Parum, an economist with the group, says corn producers face losses of $131 per acre this year, rising to $167 in 2027, while soybean losses stand at $80 per acre this year and $138 next year. She says 2027 marks the sixth year of negative returns for most major U.S. row crops.

Farm groups say the administration’s proposed $11 billion aid package does not fully offset the damage. Many producers also argue that earlier trade policies, especially tariffs that hurt soybean exports to China, have added to years of weak prices and falling incomes.

Drought and inflation risks widen the impact

Farmers and economists say the conflict’s effect extends beyond direct input costs. Slower traffic through the Strait of Hormuz pushes up diesel prices and disrupts global fertilizer supply, while drought and heat across the Corn Belt add another layer of risk to yields and revenue.

The average nationwide diesel price rises to $5.45 a gallon from $3.81 before the war, according to the U.S. Energy Information Administration. Brad Lubben, an agricultural economics professor at the University of Nebraska-Lincoln, says interest payments, labor costs and machinery prices also climb substantially across production budgets.

Pam Johnson, a farmer in northern Iowa and former president of the National Corn Growers Association, says the war creates severe uncertainty for farm businesses. John Dittrich, who farms near Meadow Grove, Nebraska, says extreme weather and rising costs make risks to his operation higher than at any point in his 44-year career.

Weather stress is also affecting markets. December U.S. corn futures rise 10 per cent this month to $5.15 a bushel, the highest level since 2023, as traders cut expectations for the 2026 harvest. With soybeans and wheat also rallying, analysts warn that food inflation could intensify while consumer finances remain under pressure ahead of the midterms.

Nebraska is among the hardest-hit states, receiving 11.86 inches of precipitation from January to July, about 3.1 inches below normal, making it the 18th-driest such period since records began in 1895. Recent rainfall brings limited relief, but farmers say much of the crop damage has already been done.

Our earlier article on expanded U.S. sanctions on Iran explained how Washington targeted dozens of entities, individuals, and vessels tied to military procurement, cyber activity, and petroleum and petrochemical trading. We noted that the measures freeze U.S.-controlled assets, restrict transactions by U.S. persons, and heighten compliance risks for banks, shippers, and commodity-market intermediaries with Iran-linked exposure.
