Strait of Hormuz Closure and Fertilizer Supply Risks for U.S. Agriculture
The early market response to the Hormuz disruption points to a concentrated rather than broad-based risk for U.S. agriculture. Energy markets reacted most sharply, but in fertilizer markets the strongest response has so far been concentrated in nitrogen products, especially urea, where prices rose by more than 28% within three weeks. Historical experience suggests the current effects may still be in an early phase. Fertilizer prices often continue to rise for several months after the initial disruption.

The closure of the Strait of Hormuz has triggered significant concerns about the potential impact on global fertilizer supply chains, with implications for U.S. agriculture. While energy markets have shown sharp reactions to the disruption, the fertilizer market has experienced a more concentrated risk, particularly in nitrogen-based products like urea. Prices for these fertilizers have risen by over 28% within just three weeks, highlighting the vulnerability of the agricultural sector to geopolitical tensions in key shipping routes.
The Strait of Hormuz, a narrow waterway between the Persian Gulf and the Gulf of Oman, is a critical chokepoint for global oil and gas transportation, accounting for about 30% of global marine oil exports. Its closure, even temporarily, can disrupt not only oil prices but also the supply of fertilizers that rely on these hydrocarbon-derived products. Fertilizers, particularly those containing nitrogen, are heavily dependent on ammonia, which is produced from natural gas. This linkage means that any disruption in the supply of natural gas or ammonia can quickly translate into higher fertilizer prices.
In the initial stages of the Hormuz disruption, energy markets reacted most sharply, with oil prices spiking significantly. However, the fertilizer market has shown a more targeted response, with nitrogen-based fertilizers, such as urea, experiencing the most dramatic price increases. Urea, a widely used fertilizer, has seen prices rise by more than 28% in just three weeks. This sharp rise is a direct result of concerns about the potential shortage of ammonia, the primary nitrogen source for urea production.
Historical data suggests that the current effects of the Hormuz disruption may still be in the early stages. Fertilizer prices often continue to rise for several months after an initial disruption, as markets adjust to the new supply dynamics and producers scramble to find alternative sources or increase production to meet the heightened demand. This prolonged period of price volatility could have significant implications for U.S. agriculture, particularly for farmers who rely on fertilizers to maintain crop yields.
The concentrated risk in the fertilizer market is a cause for concern for U.S. agriculture, as the sector heavily depends on fertilizers to support crop production. Rising fertilizer prices could lead to increased production costs for farmers, potentially reducing profit margins and limiting their ability to invest in new technologies or expand operations. Moreover, higher fertilizer costs could translate into higher food prices for consumers, further impacting the agricultural economy.
In addition to the direct impact on farmers, the Hormuz disruption could also have indirect effects on U.S. agriculture. For instance, increased fertilizer prices might lead to a decrease in agricultural exports, as foreign buyers face higher costs. This could reduce demand for U.S. agricultural products, affecting industries that rely on exports for a significant portion of their revenue.
As the situation in the Strait of Hormuz continues to evolve, it remains uncertain how long the disruption will last and what its full implications will be for global fertilizer markets. However, the early market response serves as a stark reminder of the interconnectedness of global supply chains and the potential for geopolitical events to have far-reaching effects on industries like agriculture.
In conclusion, the closure of the Strait of Hormuz has highlighted the vulnerability of the global fertilizer market, particularly for nitrogen-based products like urea. While energy markets have shown sharp reactions, the fertilizer market has experienced a more concentrated risk, with prices already rising significantly. Historical precedent suggests that this is likely just the beginning, with fertilizer prices likely to continue rising for several months. This development poses a considerable challenge for U.S. agriculture, as rising fertilizer costs could lead to increased production expenses for farmers, reduced agricultural exports, and higher food prices for consumers. As the situation unfolds, it will be crucial for policymakers and industry stakeholders to monitor the evolving landscape and explore potential strategies to mitigate the impacts on the agricultural sector.
