Strait of Hormuz conflict slashes fertilizer flows, raising risks of sharply higher wheat and feed costs. Traders brace for shifts in grain trade and volatility.
Global fertilizer trade has been hit hard by the ongoing Strait of Hormuz crisis linked to the Iran war, prompting the International Chamber of Commerce (ICC) to warn that, in a severe and prolonged disruption scenario, world cereal prices could climb by more than 80% above 2020 levels. While spot wheat quotations have not yet reflected such an extreme move, fertilizer shortages and surging logistics costs are already reshaping trade flows and risk premia along the agrifood supply chain.
The Strait of Hormuz remains effectively closed to most fertilizer and energy shipments more than six months into the conflict, curtailing a route that previously handled around one-third of global seaborne fertilizer trade and a significant share of nitrogen and phosphate exports.
Headline
Hormuz Fertilizer Shock Raises Risk of Sharp Grain Price Surge, ICC Models Show
Introduction
According to new modelling commissioned by the ICC, a sustained disruption to fertilizer and energy flows via the Strait of Hormuz could lift global cereal prices by as much as 81% compared with 2020, with the heaviest burden falling on low-income, net-importing countries. The analysis links the fertilizer shock directly to reduced application rates, lower yields and tighter exportable surpluses for key staples.
The Hormuz corridor is a critical conduit for both fertilizer and energy. Persian Gulf producers and shippers moving through the strait account for roughly 40% of global urea trade and substantial volumes of ammonia and phosphates, making current disruptions a structural risk to future grain and oilseed supplies rather than just a temporary freight issue.

Immediate Market Impact
With fertilizer cargoes out of the Persian Gulf region largely halted, nitrogen prices have risen sharply since the onset of the conflict, though they remain below the peaks seen during the 2022 Ukraine-related energy shock. Importing regions in Asia, Africa and Latin America are facing both higher input costs and difficulty securing volumes, especially for urea and ammonia.
On the grains side, futures for wheat, corn and soybeans have firmed in recent weeks on exchanges as traders price in tighter input availability and escalating geopolitical risk, with corn and soybean contracts showing particular sensitivity to fertilizer headlines. Physical wheat offers indicate moderate week-on-week moves rather than a spike, but the structure of the forward curve increasingly reflects a risk premium for 2027 crop years as concerns about reduced fertilizer use feed into yield expectations.
Supply Chain Disruptions
The closure of Hormuz has disrupted established fertilizer export channels from Iran, Qatar, Saudi Arabia and the UAE, forcing buyers in Asia and Africa to seek alternative origins, often at higher freight and insurance costs. War-risk premiums and rerouting via longer paths are inflating delivered prices and complicating shipment scheduling ahead of key planting windows.
Export restrictions by several producer countries, introduced to protect domestic availability, have further tightened the internationally tradable pool of nutrients. WTO analysis suggests that up to 15% of global fertilizer trade has at times been affected by export curbs since the Gulf conflict escalated, magnifying market stress. Developing countries with high import dependence, such as many in Sub-Saharan Africa and Southeast Asia, are particularly exposed to delivery delays and credit constraints for high-priced cargos.
Commodities Potentially Affected
- Wheat – Highly responsive to nitrogen application rates; sustained fertilizer shortages could depress yields in major exporters and import-dependent MENA and Asian markets, raising milling and feed wheat prices.
- Corn (maize) – One of the most fertilizer-intensive crops; current futures gains already reflect concern that farmers may cut application rates or acreage in the upcoming seasons.
- Soybeans – Less nitrogen-dependent than corn but still exposed via phosphate and potash availability, with Brazil in particular sensitive to imported fertilizers for its export-oriented oilseed sector.
- Rice – Heavy urea user in Asia; high nitrogen prices could lead to reduced fertilization, threatening yields in key exporters and further tightening global staple markets.
- Animal feed and livestock products – Higher grain and oilseed prices would raise feed costs, pressuring margins for poultry, pork and dairy producers and eventually lifting meat and dairy prices.
- Fertilizer-linked industrial crops (sugar, palm oil, cotton) – Input rationing may trim yields or shift cropping decisions, particularly in regions where farmers face tight credit and limited subsidy support.
Regional Trade Implications
FAO analysis highlights that the Middle East conflict has increased systemic risk across global agrifood systems, with low-income food-deficit countries most vulnerable to fertilizer-driven yield shocks. Import-dependent Asian markets such as the Philippines and parts of South Asia are scrambling to diversify fertilizer supply away from the Gulf, seeking additional volumes from China, North Africa and the former Soviet Union.
Grain trade flows are likely to tilt further toward exporters with secure fertilizer access and relatively stable energy costs, including North America, parts of Europe, and South America, although higher input prices may still weigh on margins. At the same time, tight global balances could reinforce the role of Black Sea and EU origins in supplying MENA buyers, even as separate security issues in the Black Sea add another layer of freight and insurance risk.
Market Outlook
In the near term, traders should expect elevated price volatility across fertilizer and grain markets as headlines shift between conflict dynamics, policy responses and any signs of reopening or partial de-escalation in Hormuz. The ICC’s 81% cereal price surge scenario represents a tail-risk outcome, but one that is gaining market attention as disruptions persist.
Key variables to monitor include the duration of the strait closure, the scope and length of fertilizer export restrictions, and the ability of alternative producers to ramp up output and logistics. Policy moves such as temporary tariff reductions, subsidy packages or coordinated international financing for fertilizer imports could moderate the shock, but structural risks to 2027 crop yields and global food security will remain elevated until normal trade through Hormuz resumes on a durable basis.
CMB Market Insight
The current Hormuz-driven fertilizer shock is less visible in today’s spot grain prices than in input markets, but it is fundamentally a forward supply story. For commercial hedgers and physical players in wheat and feed grains, the strategic challenge is to manage a multi-season risk in which reduced fertilizer use could compress global exportable surpluses just as demand for imports from MENA, Sub-Saharan Africa and parts of Asia remains inelastic.
Procurement and risk managers should reassess origin diversification, logistics flexibility and coverage horizons, with particular attention to 2027 and 2028 crops. Locking in fertilizer where possible, securing optionality across origins, and using structured hedging strategies around key planting and application windows may be critical to navigating a market in which input shocks, rather than current harvest volumes, increasingly set the tone for grain and oilseed pricing.
