Iran War Disrupts Global Fertilizer Supplies and Drives Food Prices Higher

The closure of the Strait of Hormuz threatens global fertilizer supplies, which could lead to increased food prices and supply chain disruptions worldwide.

• On February 28, 2026, U.S. and Israeli airstrikes initiated the 2026 Iran War, prompting Iran to close the Strait of Hormuz.
• Fertilizer prices surged, with urea prices rising by $80 per metric ton globally and Middle East ammonia prices increasing by 92% year-over-year.
• Commercial shipping is halted, idling hundreds of tankers and disrupting vital supply routes for agricultural inputs.

• The Strait of Hormuz is a critical chokepoint for global trade, handling one-fifth of the world's oil and one-third of fertilizer ingredients.
• Pre-existing market vulnerabilities from previous disruptions, such as Russian gas shortages and Chinese export restrictions, have intensified the impact of this conflict.
• Regional fertilizer producers account for nearly half of global urea exports and a significant portion of ammonia exports, making their operational status crucial for global supply.

The 2026 Iran War has triggered a complex chain of events that disrupts not only regional stability but also global agricultural supply chains. The U.S. and Israeli airstrikes targeted Iranian military infrastructure, which Iran retaliated against by closing the Strait of Hormuz. This strategic waterway is vital for the transit of goods, especially fertilizers, which are essential for crop production.

With Iran's blockade, shipping through the Strait has come to a standstill, leading to a backlog of vessels and a significant increase in shipping costs. Insurance premiums for vessels operating in the region have skyrocketed due to the heightened risk, further complicating logistics for fertilizer suppliers. As a result, many fertilizer plants, including Qatar's QAFCO, have had to shut down operations, exacerbating the supply crunch.

The immediate effect has been a sharp rise in fertilizer prices. Urea, a key ingredient for nitrogen fertilizers, saw a price increase of $80 per metric ton, reaching $683 at U.S. import hubs. Similarly, ammonia prices surged by 92% year-over-year as of March 10, 2026. These price hikes are not just an isolated phenomenon; they reflect a broader trend of escalating agricultural input costs that could ripple through to consumer prices for food.

Farmers globally are facing procurement delays and yield concerns as they prepare for planting seasons. The U.S. Agriculture Secretary has indicated that measures are being considered to mitigate these rising costs, but the effectiveness of such interventions remains to be seen. Economists are warning that these disruptions could lead to a significant impact on global food supply chains, with grain futures already reflecting surges as producers rush to secure sales amid uncertainty.

• Farmers: Facing higher input costs and potential supply shortages, impacting crop yields and profitability.
• Agricultural suppliers: Experiencing procurement delays and rising prices for essential inputs.
• Consumers: Likely to see increased food prices as agricultural costs rise, affecting household budgets.
• Shipping companies: Struggling with halted operations and increased insurance costs, impacting their profitability.
• Investors in agricultural commodities: Experiencing volatility in grain and fertilizer markets, affecting investment strategies.

• Fertilizer price trends: Monitoring price fluctuations will be crucial as they directly impact agricultural production costs and food prices.
• U.S. government interventions: Any announcements regarding cost mitigation measures for farmers could influence market dynamics and consumer prices.
• Geopolitical developments: Changes in the conflict status or negotiations could either ease or exacerbate supply chain disruptions.
