iran war will cause world shortages of food do to fertilizer Conflict in Iran is severely disrupting the global fertilizer supply, creating a high risk of worldwide food shortages and soaring prices. As of late March 2026, the blockade of the Strait of Hormuz has stalled shipments, as roughly one-third of the global seaborne fertilizer trade passes through this critical artery, threatening the spring planting season. WSJ Key impacts of the Iran war on the fertilizer and food supply include: Massive Shortages: The Strait of Hormuz is a major export route for Middle Eastern nitrogen fertilizers. Additionally, attacks on infrastructure, such as in Qatar, have reduced the production of urea, a critical fertilizer for global food production. Soaring Prices: Fertilizer prices have already surged by around 30% in some regions, with farmers experiencing severe difficulties securing supply ahead of the planting season. Global Impact: The shortage is not limited to the Middle East, with producers in India, Pakistan, and Brazil facing shutdowns due to lack of raw materials. The reduction in fertilizer availability is expected to lower crop yields and cause food shortages in the coming 6–12 months. Long-Term Consequences: The disruption of natural gas and ammonia production, which are essential for manufacturing, implies that the shortage of fertilizer could persist even if the immediate conflict ends quickly. NPR This disruption is compounded by higher energy costs, creating a "double-shock" of limited food supplies and higher production costs, leading to widespread concern over global food security Beloud
