How the Conflict in Iran is Driving Global Fertilizer and Food Price Hikes

The ongoing conflict involving Iran and the disruption of the Strait of Hormuz have triggered a significant crisis in the global agricultural sector. Because approximately 20 percent of the world’s liquified natural gas transits through this critical waterway, the instability has caused global energy prices to surge. This volatility directly impacts the production of nitrogen-based fertilizers, such as urea, which rely heavily on natural gas both as a raw material and as a primary fuel source for the energy-intensive Haber-Bosch manufacturing process.

As fertilizer costs climb—with U.S. prices for urea rising significantly since the conflict began—farmers are facing a difficult economic reality. Synthetic nitrogen fertilizer is essential for modern agriculture, as it is estimated to support the food supply for roughly half of the global population. When farmers cannot afford these inputs, they are forced to reduce application rates, which inevitably leads to lower crop yields. This reduction in productivity threatens to tighten food supplies and drive up grocery prices for consumers worldwide.

The implications of this supply chain disruption are severe, with the United Nations World Food Program warning that rising costs could push an additional 45 million people into acute food insecurity. As farmers in the Northern Hemisphere navigate the current planting season, the combination of high operational costs and market uncertainty creates a precarious situation. Ultimately, the conflict highlights the fragile dependency of global food security on energy markets, suggesting that the instability in the Middle East will continue to be felt directly on dinner plates across the globe.
