The stability of the global agricultural sector is facing its most significant challenge in decades following the closure of the Strait of Hormuz on February 28, 2026. This critical maritime chokepoint, which serves as the primary artery for energy and chemical exports from the Persian Gulf, has been severed, leading to a profound "compound shock" that threatens to destabilize food systems across the planet. According to a new policy brief released by the International Chamber of Commerce (ICC), the disruption has not only spiked the costs of essential farming inputs but has also fundamentally altered the economics of agricultural production for the upcoming planting seasons.
Before the closure, the Strait of Hormuz was responsible for the passage of approximately 40% of the world’s urea trade—a nitrogen-based fertilizer essential for high-yield crop production. Furthermore, the route handled nearly 20% of the global oil supply and more than 20% of the global liquefied natural gas (LNG) trade. Because natural gas is the primary feedstock for nitrogenous fertilizers, the closure created a dual crisis: a direct shortage of finished fertilizer products and a massive surge in the energy costs required to manufacture them elsewhere. The ICC’s analysis highlights that the crisis is no longer just a localized geopolitical event but a systemic threat to international public health, labor productivity, and social stability.
Chronology of the Crisis: From Closure to Market Contraction
The timeline of the current crisis began in early 2026, following a period of escalating regional tensions that culminated in the total suspension of maritime traffic through the Strait on February 28. The immediate market reaction was swift and severe. Between February and April 2026, the World Bank’s global fertilizer-price index surged by 44%. The impact on urea—the most widely used nitrogen fertilizer—was even more pronounced, with the benchmark price increasing by 82% in just sixty days.
By mid-March 2026, the disruption had moved beyond the shipping lanes and into the production facilities of the Persian Gulf. Industry data suggest that at the height of the crisis, between 55% and 60% of Middle Eastern urea production was either halted or significantly curtailed. This was due to a combination of infrastructure damage at key ports, constrained storage capacity as inventories backed up, and the simple inability to export the product to international markets.
By the second quarter of 2026 (April through June), the market entered a phase of "demand destruction." Approximately 3.7 million tonnes of urea demand vanished during this period. This was not a sign of a cooling market, but rather a signal that farmers—particularly those in developing nations—were being priced out. Many chose to postpone purchases, reduce the volume of application, or abandon certain crops entirely. As of August 2026, while prices have retreated from their record peaks, the underlying supply chain remains fractured, and the long-term effects on harvest yields are only beginning to be understood.
The Energy-Fertilizer Nexus and Economic Cascades
To understand the depth of this crisis, it is necessary to examine the technical link between energy and food. Urea production relies on the Haber-Bosch process, which requires significant amounts of natural gas to synthesize ammonia. With more than one-fifth of the world’s LNG supply passing through the Strait of Hormuz, the closure triggered an immediate spike in energy costs for fertilizer plants in Europe, Asia, and North America.
The ICC report notes that the direct loss of Gulf supply was amplified by a cascade of secondary costs. Shipping companies were forced to reroute vessels around the Cape of Good Hope, adding weeks to transit times and significantly increasing fuel consumption. Simultaneously, marine insurance premiums for any vessels operating in the vicinity of the Middle East skyrocketed, while financing costs for commodity traders rose in tandem with the perceived risk.
The result was a market where fertilizer was not only more expensive to buy but also more expensive to manufacture, finance, and deliver. In many instances, the ICC found that certain trade routes became "commercially unviable," leaving landlocked or geographically isolated nations without any reliable access to the nutrients required for their soil.
The Illusion of Price Recovery
One of the most critical warnings in the ICC policy brief concerns the recent decline in international urea benchmarks. While some analysts have pointed to falling prices as a sign of recovery, the ICC argues this is a dangerous misinterpretation. Prices have eased not because the supply chain has been fully restored, but because of a massive drop in demand.
When farmers stop buying fertilizer because they cannot afford it, the price naturally falls. However, this "stability" comes at a catastrophic cost: lower future agricultural production. The ICC notes that the consequences of reduced fertilizer application are "lagged." Decisions made by farmers in the spring of 2026 will not be fully visible until the harvests of late 2026 and 2027. This delay creates a "political blind spot" where governments may feel the crisis has passed, even as a food supply shortfall is being baked into the system.
Furthermore, the recovery has been uneven. While some wealthier nations have provided public support and subsidies to help their agricultural sectors absorb the shock, farmers in low-income, food-deficit countries have been left to face the market volatility alone. This disparity is creating a widening gap in global food security.
Scientific Modelling and Human Impact
To quantify the potential fallout, the ICC commissioned a study from researchers at the University of Edinburgh, the University of Aberdeen, and Scotland’s Rural College. This early-stage, non-peer-reviewed research utilized scenario modelling to test the impact of prolonged elevated costs for fertilizer and energy.
The findings are stark. If fertilizer application remains below historical averages due to cost and availability issues, the study predicts a significant decline in the caloric and nutritional output of global agriculture. This would lead to higher food prices for consumers and a corresponding increase in undernourishment, particularly in regions that rely heavily on imported staples.
The modelling suggests that the shock could lead to a "dietary health crisis" in vulnerable populations. Beyond the direct health implications, the study warns of a "vicious cycle" where lower agricultural yields lead to reduced rural incomes, which in turn reduces labor productivity and can trigger social unrest. The researchers emphasize that the "test" for a successful recovery is not the price of urea on a screen in London or New York, but whether the physical product reaches the hands of smallholder farmers in time for their local planting windows.
Six Strategic Priorities for Global Action
In response to these findings, the ICC is calling for a coordinated international effort to mitigate the damage and protect future harvests. Alongside the obvious need for a cessation of hostilities and the reopening of the Strait of Hormuz, the ICC has outlined six policy priorities:
- Trade Corridor Protection: Governments must work together to ensure that agricultural inputs like fertilizer are treated as "essential goods," similar to medical supplies, and are given priority in shipping and logistics.
- Financial Liquidity for Importers: Multilateral institutions, such as the World Bank and IMF, should provide emergency credit lines to low-income countries to ensure they can afford to purchase fertilizers despite the high costs of insurance and transport.
- Transparency in Global Stocks: There is an urgent need for better data on fertilizer inventories. The ICC recommends the expansion of the Agricultural Market Information System (AMIS) to include more granular data on fertilizer stocks to prevent panic buying and hoarding.
- Support for Smallholder Farmers: National governments should prioritize direct support to small-scale farmers, who are the most likely to "demand destruct" when prices rise. This includes subsidies, micro-financing, and technical assistance in optimizing fertilizer use.
- Rejection of Export Bans: The ICC strongly discourages nations from implementing export restrictions on fertilizers or energy. Such "beggar-thy-neighbor" policies only serve to exacerbate global shortages and drive prices higher for everyone.
- Diversification of Supply Chains: Long-term resilience requires diversifying the sources of nitrogenous fertilizers. This includes investing in "green ammonia" projects that use renewable energy rather than natural gas, reducing the sector’s dependence on volatile energy chokepoints like the Strait of Hormuz.
The Path Forward: Monitoring the September Window
As the world moves toward the next major planting cycles starting in September 2026, the ICC warns that the window for action is closing. Fertilizer purchasing is expected to rise as farmers prepare for the next season, and without significant intervention, this could trigger a renewed price spike.
"Success should be measured not by the movement of a global price index, but by whether fertilizer reaches the farmers who need it, when they need it, to protect future harvests," the ICC stated in its conclusion. The organization is urging world leaders to remain focused on the agricultural sector, even if energy prices show signs of stabilization. The "lagged effect" of the Hormuz closure means that the true peak of the food crisis may still be months away.
The international community now faces a choice: act decisively to shore up agricultural value chains or wait for the harvest failures of 2027 to force their hand. With millions of lives and the stability of the global economy at stake, the ICC’s policy brief serves as a final warning that food security cannot be maintained if the inputs of production are treated as an afterthought in geopolitical strategy.
