How the Iran War Is Disrupting Global Fertilizer Supply

Summary

• The war in Iran and the resulting closure of the Strait of Hormuz has created a severe, unprecedented supply shock for nitrogen and phosphate fertilizers, distinct from prior crises.
• About one-third of the world's urea (the most common nitrogen product) flows through the Strait of Hormuz, with Iran, Qatar, and Saudi Arabia representing three of the top ten global urea exporters.
• The disruption has halted shipments and is now forcing production cuts in the Persian Gulf due to finite on-site storage, with the shockwave extending to major manufacturers like those in India who rely on Middle Eastern gas as an input.
• For U.S. farmers, the timing is critical: even if shipments resumed immediately, the logistics chain means fertilizer would not reach inland farms until mid-May, which is too late for the current planting season.
• Farmers face a "double whammy" of soaring fuel and fertilizer input costs (fertilizer is ~25% of costs) while dealing with weak crop commodity prices, severely squeezing margins.
• The immediate crisis is specific to nitrogen (urea) and phosphate; potash from Canada is presented as a more stable, geopolitically secure alternative but is not a perfect substitute.
• The fertilizer price spike is a direct conduit to higher global food prices, posing a significant risk of renewed inflation and disproportionate hardship for low-income populations.
• Market-based hedges (e.g., CME futures) exist but cannot solve the physical supply shortage in the truncated timeframe before planting.
• The speaker from StoneX emphasizes this is a unique event with no historical comparison in the fertilizer market over the last 24 years.
