The War You'll Feel at the Grocery Store

The missile strikes made headlines. The fertilizer shortage will hit your wallet.

When the Strait of Hormuz closed in late February 2026, the world's attention snapped to oil prices. Understandably so—roughly 20% of global crude oil trade passes through that narrow chokepoint, along with a similar share of liquefied natural gas. But tucked alongside those tankers is another cargo that rarely makes the front page: nearly a third of all internationally traded fertilizer.

Fertilizer doesn't explode. It doesn't make for dramatic footage. But remove it from the equation, and the global food system starts to buckle in ways that play out slowly, stubbornly, and long after any ceasefire is signed.

Three Crops. Three Nutrients. One Chokepoint.

Corn, wheat, and rice together supply more than half of humanity's dietary calories. To maximize yields, all three depend on three core nutrients: nitrogen (which drives plant growth), phosphorus (critical for root development and seed formation), and potassium (which helps plants retain water and build protein).

The Hormuz closure hit all three at once.

Natural gas determines 70 to 90% of the cost of producing nitrogen fertilizer. The war has already cut natural gas production by 20% and driven prices up by as much as 70%. Russia, protecting its own reserves, suspended exports of ammonium nitrate—a key nitrogen source. China, the world's largest phosphate producer, blocked phosphate exports, erasing 25% of global supply overnight. And potash, the potassium-rich fertilizer component, was already scarce before the war, squeezed by years of sanctions on Belarus and Russia.

The result: in the U.S., some fertilizer prices surged more than 40% in a single month after fighting began.

Timing Is Everything—And the Clock Is Already Running

The deeper problem isn't just cost. It's timing.

Corn plants absorb the bulk of their nitrogen during early growth. Miss that window—or apply 10 to 15% less fertilizer, or delay by just two to four weeks—and yields fall by 10 to 25%. There's no making it up later in the season.

In mid-March 2026, U.S. fertilizer supply sat at roughly 75% of normal levels—precisely when Corn Belt farmers begin their first spring applications. Subsequent applications run from mid-April through mid-June. Government loan guarantees and aid packages can help farmers absorb higher costs, but they cannot conjure fertilizer that simply doesn't exist in time.

Faced with that reality, farmers are already making hard calls: plant less corn, switch to soybeans (which need less fertilizer), or reduce application and accept lower yields. Every option shrinks the corn supply.

From Farmgate to Your Fridge: The Lag Effect

Food price increases don't arrive all at once. They travel through the supply chain in waves, and understanding that rhythm matters.

When corn prices rise, feed costs for livestock follow. Higher feed costs push up the price of chicken, pork, and beef. In 2012, a Midwest drought cut U.S. corn yields by 13%—and poultry prices rose 20% as a result. When feed becomes truly unsustainable, farmers don't just cut production; they liquidate breeding stock. In 2022, a combination of drought and high costs forced U.S. producers to cull 13.3% of the national beef cow herd—the highest proportion ever recorded—shrinking the cattle inventory to its lowest level since 1962. That kind of structural damage takes years to reverse.

The USDA, using pre-war data, had already projected a 3.1% average food price increase for 2026. That number is almost certainly outdated now.

The timeline varies by product. Corn tortillas and minimally processed corn foods will reflect price changes within a few months. Poultry and cereals take a little longer. Beef—with more steps between feed purchase and store shelf—takes longest. Fuel surcharges on freight are already being added. Packaging costs will follow. Low-income households, who spend a larger share of their income on food, will feel each wave more sharply than others.

A Global Problem with Local Consequences

For Americans, this war hasn't meant gas lines or power outages. But the grocery bill is coming.

And for much of the rest of the world, the situation is more urgent. More than 300 million people already lack sufficient food. The U.N. World Food Programme warns that if the Middle East conflict continues into mid-2026, an additional 45 million people could join them. Crop yields in India and Brazil are already expected to fall below normal. East African farmers were struggling to afford fertilizer before the crisis; they'll have even less now.

Food markets are global. A smaller U.S. corn harvest, combined with rising demand from China and India, will push global corn prices higher—affecting consumers regardless of nationality or geography.
