How the Iran War's Impact on Fertilizer Supplies Affects Global Food Prices (2026)

The ongoing conflict in Iran has sparked concerns about the global supply of fertilizer, a critical component in agriculture. The Strait of Hormuz, a key shipping route for fertilizer, has been closed due to the war, causing a significant disruption in the market. This has led to a rise in fertilizer prices and a global shortage, affecting countries that heavily rely on imported fertilizer. The situation has particularly impacted U.S. farmers, who are now facing higher costs and limited availability of fertilizer just as they prepare for the growing season.

The impact on U.S. farmers is twofold. Firstly, about one-third of the fertilizer used by American farmers is imported, and a significant portion of this comes through the Strait of Hormuz. With the strait closed, the market dynamics have shifted, causing a ripple effect on global fertilizer prices. Secondly, the war has also led to a global shortage of natural gas, a crucial component in nitrogen fertilizer manufacturing, further exacerbating the issue.

The consequences for U.S. farmers are already evident. A survey conducted by the American Farm Bureau Federation revealed that 70% of respondents couldn't afford the necessary fertilizer for the current season. Producers of corn and wheat, which heavily rely on fertilizer, are particularly vulnerable. These farmers spend around a third of their operating costs on fertilizer, and many are now considering reducing the amount of fertilizer applied to their crops due to higher costs and limited availability.

However, the impact on U.S. grocery prices is expected to be relatively modest. Food inflation is generally driven by broader factors such as labor and fuel costs, rather than fertilizer prices. While higher fertilizer costs may lead to smaller harvests and modest retail price hikes, the overall effect on food prices is likely to be contained. The majority of the cost burden will be borne by farmers, who have limited bargaining power to negotiate higher crop prices.

The situation in Africa and Asia is more dire. Poorer countries in these regions heavily rely on fertilizer from the Persian Gulf, and the reduction in shipments through the Strait of Hormuz could have severe consequences. Countries like Sudan, Sri Lanka, Tanzania, and Somalia are particularly vulnerable to the disruption in fertilizer supply.

The fertilizer industry is gradually recovering, with prices starting to stabilize as the U.S. and Iran reached a deal to reopen the Strait of Hormuz. The Trump administration has also taken steps to lower fertilizer costs for American farmers by temporarily suspending countervailing duties on certain phosphate imports. However, it will take time for the industry to return to normal, and the recovery process may impact U.S. farmers' planting plans for the upcoming autumn season.

This crisis has prompted farmers to reevaluate their strategies. Many are now exploring alternative methods to replenish soil nutrients, such as using manure, compost, and cover crops, to reduce their reliance on fertilizer. This shift in mindset could have long-lasting effects on the agricultural industry, encouraging a more sustainable and resilient approach to farming.
