Fertilizer Shortages, the Strait of Hormuz, and Grain Markets: A 2026 Reality Check
The Thesis
One of the more interesting commodity theses to emerge in 2026 has been the idea that disruptions in the Strait of Hormuz could lead to fertilizer shortages, which in turn could reduce global grain production and drive corn and wheat prices higher.
The logic is straightforward. The Gulf region is a major exporter of nitrogen fertilizers, and a significant portion of global fertilizer trade normally passes through the Strait of Hormuz. When tensions in the region escalated and shipping was disrupted, fertilizer prices quickly moved higher and concerns about supply shortages spread throughout agricultural markets.
What We Found
After reviewing USDA reports, crop condition data, fertilizer market developments, and industry commentary, our conclusion is:
- There is currently limited evidence that fertilizer shortages have materially affected the 2026 U.S. corn crop.
- Poor winter wheat conditions appear to be primarily driven by drought rather than fertilizer availability.
- The strongest version of the fertilizer-shortage thesis may be a 2027 story rather than a 2026 story.
Corn: Little Evidence of Current Crop Stress
Most corn fertilizer is purchased and applied before planting. By the time fertilizer markets became a major concern, much of the 2026 U.S. corn crop had already been planted and fertilized.
Recent USDA Crop Progress reports have shown corn conditions remaining relatively stable, with no obvious signs of widespread nutrient stress. While fertilizer prices have increased and some producers have reported concerns about costs, current crop health data does not suggest a broad reduction in yields attributable to fertilizer shortages.
This does not mean fertilizer markets are unimportant. It simply means the expected effects have not yet appeared in the data.
Wheat: A Different Story, But Not the One We Expected
Winter wheat conditions have been poor across parts of the Great Plains. However, USDA reports and industry commentary consistently point to drought as the primary cause.
In its June crop updates, USDA reduced portions of the winter wheat outlook while analysts and industry observers continued to attribute much of the weakness to drought conditions across key wheat-producing regions. The hardest-hit areas overlap closely with regions experiencing significant moisture deficits, making drought a more compelling explanation than fertilizer shortages.
As a result, wheat has experienced genuine production concerns, but the evidence does not currently support the conclusion that fertilizer availability is the primary driver.
Why 2027 May Matter More Than 2026
The most interesting risk may lie ahead.
If fertilizer prices remain elevated or supply remains constrained through the second half of 2026, farmers could respond by:
- Reducing fertilizer application rates
- Shifting acreage away from fertilizer-intensive crops such as corn
- Altering planting decisions for the 2027 season
Those effects would likely appear first in fertilizer purchasing data, acreage intentions, and farmer surveys before showing up in actual yield numbers.
The reports worth watching are USDA's monthly World Agricultural Supply and Demand Estimates (WASDE), weekly Crop Progress reports, and the annual acreage and planting intention reports released by USDA.
In other words, markets could begin pricing the risk long before harvest confirms it.
Conclusion
At present, the evidence suggests that fertilizer disruptions are primarily a pricing and input-cost story rather than a crop-damage story.
The key question is whether elevated fertilizer costs persist long enough to influence planting decisions for the 2027 growing season.
For now, the thesis remains worth monitoring, but the strongest evidence may still lie ahead.
