When the Strait of Hormuz—a narrow waterway connecting the Persian Gulf to the Gulf of Oman—becomes a flashpoint in geopolitical tensions, the consequences ripple far beyond oil markets. Nearly one-third of the world’s fertilizer shipments pass through this critical choke point, and disruptions are now stalling millions of metric tons of supply each month. The result? A sharp rise in nitrogen prices that threatens to destabilize global food systems, particularly in vulnerable regions where staple crops like wheat, rice, and corn rely on synthetic fertilizers to meet demand.

This isn’t just an economic issue—it’s a public health crisis in the making. Fertilizers like urea, a nitrogen-rich compound derived from natural gas, are the backbone of modern agriculture. Without them, yields drop, food prices spike, and malnutrition rates climb. In countries already grappling with inflation and political instability—such as Bangladesh, India, and Kenya—the fallout could be severe. The question now is whether governments and international institutions can act fast enough to prevent a sustained food insecurity crisis.

Why Fertilizers Are the Hidden Vulnerability in the Strait of Hormuz Crisis

The Strait of Hormuz isn’t just a conduit for oil—it’s a lifeline for global agriculture. According to the International Fertilizer Development Center (IFDC), approximately 30% of the world’s urea fertilizer is transported through this narrow passage. Urea, produced via the energy-intensive Haber-Bosch process, is essential for boosting crop yields, particularly in regions where soil quality is poor or rainfall is unpredictable.

When shipping routes are disrupted—whether by conflict, blockades, or heightened insurance premiums—the cost of transporting urea skyrockets. Insurers now factor in war risk premiums, and cargo owners must weigh the financial and logistical risks of navigating the strait. Even if the waterway remains technically open, the perception of instability can paralyze trade. As The Financial Times reported earlier this month, a single incident—such as an attack on a vessel or the imposition of illegal tolls—can trigger a cascading withdrawal of shipping companies, further tightening supply.

“Urea is not just a commodity—it’s a building block of the Green Revolution. Disruptions here don’t just raise prices. they threaten the very foundation of food security for billions.”

The Domino Effect: How Fertilizer Shortages Threaten Global Food Systems

1. Price Shocks and Agricultural Strain

Fertilizer prices have already surged by over 50% in some markets since the escalation of tensions in the Strait of Hormuz, according to FAO’s latest market brief. For farmers in developing nations, where fertilizer costs can account for 20–30% of production expenses, this translates to a crippling financial burden. In India, for example, smallholder farmers—who produce nearly 60% of the country’s food—are already cutting back on urea applications, leading to predicted yield losses of 10–20% for key crops like rice and wheat.

2. Regional Inequality and Political Instability

Vulnerable nations are bearing the brunt of these disruptions. Countries reliant on imported fertilizers—such as Bangladesh, where over 90% of urea is imported—face immediate risks of food shortages. The World Bank warns that prolonged fertilizer shortages could push an additional 100 million people into acute food insecurity by the end of 2026, exacerbating existing malnutrition rates.

Politically, the stakes are high. Food price volatility has historically fueled unrest. In 2008, the global food price crisis contributed to protests in over 30 countries. Today, with inflation already elevated, even modest increases in staple food costs could trigger social unrest in already fragile regions.

3. The Hidden Cost: Malnutrition and Public Health

Beyond immediate food shortages, the long-term health consequences are alarming. Fertilizer shortages lead to reduced crop diversity and lower nutritional quality. Staple grains like wheat and rice, which are often fortified with synthetic nitrogen, become less nutrient-dense, increasing the risk of micronutrient deficiencies—particularly in children. The World Health Organization (WHO) estimates that nearly 2 billion people worldwide suffer from micronutrient deficiencies, with children under five bearing the highest burden.

What Can Be Done? Three Urgent Steps to Mitigate the Crisis

1. Diversify Fertilizer Supply Chains

Relying on a single chokepoint like the Strait of Hormuz is a gamble. Governments and agricultural cooperatives must invest in alternative shipping routes, such as the East Africa–Asia corridor, or expand domestic fertilizer production. The IFDC is already working with countries like Ethiopia and Nigeria to scale up local urea production, but these efforts require urgent funding and policy support.

2. Strengthen Global Fertilizer Reserves

Just as the world maintains strategic oil reserves, a similar system for fertilizers could act as a buffer during crises. The FAO’s Global Information and Early Warning System (GIEWS) has called for the establishment of an International Fertilizer Reserve to stabilize markets during disruptions. This would involve stockpiling urea and other critical nutrients in key hubs and releasing them during shortages.

3. Coordinate Diplomatic and Economic Pressure

While military escalation risks further destabilizing the strait, diplomatic efforts to de-escalate tensions remain critical. The United Nations and regional bodies like the Gulf Cooperation Council (GCC) must work together to ensure the strait remains open to commercial traffic. International financial institutions could offer low-interest loans to farmers in affected regions to help them weather the price shocks.

Key Takeaways: What You Need to Know

• The Strait of Hormuz is a critical artery for global fertilizer trade, transporting nearly 30% of the world’s urea.
• Disruptions have already caused nitrogen prices to surge by over 50% in some markets, threatening agricultural productivity.
• Vulnerable regions—particularly in South Asia and Sub-Saharan Africa—face the highest risk of food shortages and political instability.
• Long-term solutions include diversifying supply chains, establishing fertilizer reserves, and diplomatic efforts to stabilize the strait.
• The health impact of fertilizer shortages extends beyond hunger, increasing risks of malnutrition and child stunting.

Looking Ahead: Can the World Avoid a Fertilizer Crisis?

The current blockade of the Strait of Hormuz is a warning shot. Without coordinated action, the world could soon face a perfect storm of high fertilizer prices, reduced crop yields, and escalating food insecurity. The good news? History shows that when governments act decisively—whether through trade diversification, reserve systems, or diplomatic pressure—the worst outcomes can be averted.

For now, the focus must be on resilience. Farmers need support to adapt, policymakers must prioritize food security, and the international community must treat fertilizers as the strategic commodity they are. The alternative—a world where geopolitical tensions dictate food availability—is one no one should have to endure.
