The ongoing closure of the Strait of Hormuz, now exceeding a 90-day duration, has triggered an escalating crisis in the global agricultural sector that threatens to destabilize food security for billions of people. While international attention has remained largely fixated on the volatility of crude oil and liquefied natural gas (LNG) prices, a more insidious economic threat is emerging in the form of a paralyzed fertilizer supply chain. The International Chamber of Commerce (ICC) and industry leaders, including Yara International, have warned that the inability to move nitrogen-based fertilizers through this primary maritime artery could lead to a catastrophic drop in global crop yields, particularly in the most vulnerable developing economies.
The Strategic Importance of the Strait of Hormuz to Global Agriculture
The Strait of Hormuz is widely recognized as the world’s most important oil transit chokepoint, with roughly 21 million barrels of oil passing through it daily. However, its role in the global food system is equally critical, yet far less publicized. The Middle East is a central hub for the production of urea, a nitrogen-rich fertilizer essential for large-scale agriculture. According to data provided by Yara International, approximately one-third of the world’s exported urea passes through the Strait of Hormuz.
Fertilizers are not merely another commodity in the global trade network; they are the fundamental building blocks of modern food production. Agricultural experts estimate that 50% of the world’s current food supply is a direct result of the use of mineral fertilizers. When crops are harvested, they remove essential nutrients—nitrogen, phosphorus, and potassium—from the soil. If these nutrients are not replenished through fertilization, the soil becomes degraded, leading to a precipitous decline in productivity. The 90-day blockade has effectively severed the link between major production facilities in the Persian Gulf and the global farming communities that rely on them.
Chronology of the Crisis: From Geopolitical Tension to Supply Chain Paralysis
The current crisis began to manifest in late February, following an escalation in regional conflict that led to the de facto closure of the Strait. The timeline of the disruption highlights the fragility of global "just-in-time" supply chains:
- Late February: Initial hostilities lead to the suspension of commercial shipping through the Strait of Hormuz. Fertilizer production plants in the region begin to report logistics bottlenecks as storage capacities reach their limits.
- March: Global fertilizer prices begin to decouple from historical norms. While energy prices see a sharp spike, the scarcity of physical fertilizer shipments begins to impact "prime application seasons" in the Northern Hemisphere.
- April: Major shipping companies officially reroute vessels, adding weeks of transit time and significant fuel surcharges to the cost of agricultural inputs. Reports emerge of production plants in the Middle East shutting down or reducing output due to an inability to export finished products or receive necessary precursors like ammonia and sulfur.
- May: The crisis reaches the 90-day mark. The ICC and various United Nations agencies begin formalizing proposals for a "humanitarian corridor" or specific mechanisms to allow for the movement of fertilizers and related agricultural inputs to prevent a total collapse of the next harvest cycle.
Economic Implications: The "Scissors Effect" on Global Farming
The disruption in the Strait of Hormuz has created a devastating economic environment for farmers, characterized by what economists call the "scissors effect." Farmers are facing a dual pressure: sharply rising input costs and stagnant or falling commodity prices for their crops.
On the input side, the cost of diesel for machinery, chemical pesticides, and fertilizers has surged. Because fertilizer production is an energy-intensive process—requiring natural gas to synthesize ammonia—the simultaneous spike in energy prices caused by the conflict has doubled the burden on manufacturers and, subsequently, on farmers.
Conversely, global crop prices have not risen in tandem with production costs. In many regions, crop prices have remained flat or have even seen recent decreases. This disparity has decimated farmer profitability. Many agricultural producers, particularly smallholders in developing nations, find themselves unable to afford the nutrients required to optimize their yields. This lack of affordability leads to "under-application," where farmers use less fertilizer than agronomically necessary, a decision that has long-term negative consequences for soil health and future food availability.
Regional Disparities and the Humanitarian Risk
The impact of the fertilizer shortage is not distributed evenly across the globe. Developed regions, such as Europe and North America, possess a degree of "soil resilience." In these areas, years of optimal fertilization have created a nutrient buffer in the soil. Farmers in these regions can reduce their fertilizer consumption for a single season with only a marginal impact on total yield. Furthermore, wealthier governments often have the fiscal capacity to provide subsidies or financial backstops to ensure their domestic food supplies remain secure.
In contrast, the developing world—particularly sub-Saharan Africa and parts of South Asia—faces a "steep yield curve." In these regions, many farmers are already under-applying nutrients due to historical poverty and infrastructure challenges. Any further reduction in fertilizer availability can lead to an immediate and dramatic drop in production. Studies indicated by industry leaders suggest that for certain nitrogen-dependent crops, the inability to apply fertilizer can result in a yield drop of as much as 50% in the very first harvest following the disruption.
The ICC warns that the current blockade is resulting in the loss of "billions of meals" every week as the compounding effect of the shortage takes hold. If the Strait remains closed, the world risks transitioning from a crisis of "affordability"—where food exists but is too expensive—to a crisis of "availability," where the physical supply of food is insufficient to meet global demand.
Official Responses and the Search for Diplomatic Solutions
In response to the escalating threat, the International Chamber of Commerce has been working closely with UN agencies to advocate for the reopening of the Strait specifically for agricultural trade. These discussions are centered on creating a mechanism that would allow the safe passage of vessels carrying urea, ammonia, and sulfur, even while broader geopolitical tensions remain unresolved.
Simultaneously, diplomatic efforts between the United States and Iran are being monitored closely by the global trade community. A phased reopening of the Strait or a de-escalation of hostilities is viewed as the only immediate solution to the supply chain paralysis. However, industry experts caution that even if the Strait were to reopen tomorrow, the market would not normalize instantly. The backlog of inventory, the damage to production facilities, and the loss of confidence among shipping insurers mean that the "tail" of this crisis will likely extend for months, if not years.
The Need for Structural Reform and the Fourth Agricultural Revolution
The repeated shocks to the global food system—ranging from the COVID-19 pandemic and the Russia-Ukraine war to the current Hormuz crisis—have prompted calls for fundamental structural reforms. There is a growing consensus that global supply chains are too geographically concentrated and lack the resilience needed for a century defined by geopolitical volatility.
Svein Tore Holsether, CEO of Yara International, argues that the world must embrace the "Fourth Agricultural Revolution" to mitigate these risks. This transition involves leveraging technology to move away from a volume-based approach to farming and toward a precision-based model. Key technological enablers include:
- AI and Big Data: Utilizing artificial intelligence to process hyperlocal weather patterns and soil data, allowing farmers to optimize every gram of fertilizer used.
- Satellite Imagery and Sensors: Using remote sensing technology to monitor crop health and nutrient levels in real-time, ensuring that nutrients are applied only where and when they are needed.
- Green Hydrogen and Decarbonization: Reducing the dependency of fertilizer production on volatile natural gas markets by transitioning to "green ammonia" produced with renewable energy.
Climate Goals Amidst Economic Turmoil
A significant concern emerging from the Strait of Hormuz conflict is the potential for a "climate rollback." As energy and fertilizer prices soar, some political figures and business groups in Europe and elsewhere have called for a dismantling of climate structures, such as the EU Emissions Trading System (ETS), to provide short-term economic relief.
However, global business leaders and the ICC maintain that dialing back on climate action would be a strategic error. They argue that the climate crisis and the food security crisis are inextricably linked. Farmers are among the most affected by climate change, facing increasing frequencies of droughts, floods, and heatwaves. Postponing the green transition would only push the current shocks further into the future, potentially reaching irreversible tipping points.
The business community is calling for an "enabling environment" where the green transition is made profitable for both manufacturers and farmers. This includes targeted subsidies that focus on soil health and nutrient efficiency rather than simple volume-based support.
Conclusion: A Call for Coordinated Global Action
The 90-day closure of the Strait of Hormuz has evolved into a global humanitarian and economic challenge that extends far beyond the energy markets. The disruption of the fertilizer trade threatens the very foundation of global food production, with the most severe consequences poised to strike the world’s most vulnerable populations.
As the ICC and international organizations continue to push for diplomatic and logistical solutions, the crisis serves as a stark reminder of the fragility of the global food system. The path forward requires a dual focus: immediate action to restore the flow of agricultural nutrients through the Strait of Hormuz and a long-term commitment to building a more resilient, technologically advanced, and sustainable global agricultural infrastructure. Without smart, focused, and effective policymaking, the "silent" fertilizer crisis could soon become a very loud and devastating global famine.
