The rhythmic, mechanical hum of the Port of Mombasa, usually a heartbeat of East African commerce, masks a deepening, invisible anxiety among the country’s agricultural sector as the Middle East conflict paralyzes the world’s most critical maritime chokepoints.

As the conflict between the United States, Israel, and Iran enters its third week, the impact has migrated far beyond the immediate theater of war, striking at the foundational inputs of global food production. For Kenyan smallholders preparing for the long rains, this is not merely a geopolitical headline—it is a direct threat to their upcoming harvest, the cost of their fertilizer, and the eventual price of the maize that stocks the nation’s shelves.

The Chokepoint Effect: A Global Supply Chain in Paralysis

The Strait of Hormuz, a narrow waterway separating the Persian Gulf from the Gulf of Oman, has effectively ground to a halt following weeks of military escalation. This corridor is more than a geographic feature it is the jugular vein of the global energy and agricultural chemical trade. According to market data from the International Food Policy Research Institute (IFPRI), roughly 27 percent of global oil exports and up to 30 percent of global fertilizer exports—including urea, ammonia, and phosphates—transit through this strait.

Shipping traffic through the corridor has plunged by more than 70 percent since late February, as insurance premiums for commercial vessels skyrocket and shipping lines divert to safer, albeit far longer, routes. The delay is immediate and cascading. For nations heavily dependent on imports, such as Kenya, the disruption creates a double-bind: escalating shipping costs and a shrinking availability of essential inputs that simply are not reaching their destination on time.

• Shipping Vulnerability: Over 70 percent drop in maritime traffic through the Strait of Hormuz since the conflict escalation.
• Fertilizer Dependency: Approximately 20–30 percent of global nitrogen, phosphate, and potash fertilizer exports transit the impacted region.
• Feedstock Crisis: Natural gas, the primary feedstock for nitrogen-based fertilizers, has seen prices surge by over 50 percent in major trading hubs.
• Regional Impact: Kenya’s fertilizer imports are currently facing logistical delays of 3–5 weeks as carriers reroute, coinciding with the crucial March planting season.

The Energy-Fertilizer Nexus

The economic mechanism linking the conflict in the Middle East to the dinner table in Nairobi is rooted in the Haber-Bosch process, the industrial backbone of modern agriculture. Nitrogen fertilizers, such as urea, are synthesized from ammonia, which requires massive quantities of natural gas. When the conflict limits the production and transit of natural gas from the Gulf, the feedstock costs for fertilizer manufacturing spike with algorithmic precision.

Economists at the Central Bank of Kenya warn that this inflationary pressure is likely to be sustained. While global food prices had begun a tentative stabilization following the volatility of the mid-2020s, the current energy shock risks reversing those gains. The linkage is unforgiving: as fuel prices for tractors and logistics rise, and as fertilizer prices climb—some markets reporting surges of up to 19 percent in a single week—the farmer’s margin is eroded. When the farmer cannot afford the fertilizer, crop yields suffer. When yields fall, food supply tightens, and the consumer pays the final, heavy price.

Voices From the Frontline of Agriculture

In Uasin Gishu County, the breadbasket of Kenya, the mood is one of cautious desperation. Farmers who rely on the onset of the long rains to apply nitrogen-based inputs are finding themselves in a bind. Retail prices for key fertilizers have already begun to creep upward as local distributors grapple with the uncertainty of future supply chains. Experts from local agricultural institutes suggest that if farmers decide to reduce their application rates to save costs, the harvest output could contract significantly, creating a secondary food security crisis by the third quarter of 2026.

This scenario is not isolated to Kenya. Agricultural analysts note that the vulnerability is global. Farmers across the Northern Hemisphere are facing identical choices, with some pivoting away from high-input crops like maize toward less nutrient-intensive varieties. However, for a country that remains a net importer of staple cereals and critical farm inputs, this pivot is a luxury the national market cannot afford. The dependence on globalized trade means that a drone strike in the Gulf has a measurable, immediate impact on the price of a bag of fertilizer in Nakuru.

The Path Forward: Resilience or Risk

History, from the 1973 oil crisis to the 2022 disruption of Black Sea grain corridors, demonstrates that reliance on fragile chokepoints is a systemic vulnerability. The question currently posed to policymakers is one of long-term structural adjustment. While the current diplomatic efforts to de-escalate the situation remain the priority, the realization is setting in that the current food system is too brittle to withstand such concentrated geopolitical shocks.

As the international community watches the unfolding situation in the Middle East, the quiet, persistent work of food production continues. Yet, for millions of smallholders and consumers alike, the shadow of the conflict is now the most influential factor in their economic reality. Whether this crisis accelerates a shift toward more decentralized, localized agricultural inputs or leaves the global food system exposed to the next inevitable shock remains the defining uncertainty of the year.
