UN warns Strait of Hormuz disruptions could trigger global food and fertiliser crisis
UN warns that disruptions in the Strait of Hormuz risk pushing up food and fertiliser prices, worsening global hunger and hitting vulnerable economies.
The United Nations has warned that sustained disruptions in the Strait of Hormuz could sharply raise food and fertiliser costs and push tens of millions into hunger. The UN said that if shipments of fertiliser are prevented from transiting the narrow waterway for only a few weeks, agricultural inputs would become scarce and prices could spike further. Food prices are already elevated, and aid organisations caution that prolonged interruptions to maritime traffic linked to the Iran conflict would deepen an emerging global crisis. Policymakers, shippers and relief agencies are urgently assessing the scale of the threat and possible measures to limit damage to food supplies.
UN issues urgent alert on shipping risks
The UN’s warning highlights the strategic role the Strait of Hormuz plays in global trade and the vulnerability of agricultural supply chains. Much of the world’s bulk fertiliser, as well as fuel and other commodities, passes through the strait on routes between producing regions and import-dependent countries. A disruption could create bottlenecks that ripple through supply chains, affecting planting cycles that are time-sensitive and leaving farmers with reduced access to critical nutrients. The UN cautioned that delays measured in weeks, not months, would be enough to undermine harvests in some regions.
Fertiliser shortages and agricultural consequences
Fertiliser markets reacted to the warning as traders weighed the prospect of reduced shipments and higher transport risks. Fertiliser prices have already risen steeply in recent months, driven by demand, energy costs and previous supply chain disruptions, and further increases would raise production costs for farmers worldwide. Reduced availability of nitrogen, phosphate and potassium fertilisers would likely lower crop yields, particularly in intensive systems that depend on chemical inputs for high productivity. The timing is critical: planting seasons in many countries are imminent or already under way, leaving little room to adjust if shipments are delayed.
Impact on food prices and markets
Global food prices, which are at multi-year highs, would likely climb further if the Strait of Hormuz remains intermittent to bulk shipping. Higher fertiliser costs usually translate into higher crop production costs, which then feed through to consumer food prices for staples such as wheat, maize and rice. Import-dependent and low-income countries face the greatest exposure because they cannot easily substitute domestic production at scale. Commodity markets are sensitive to supply-risk signals, and the mere expectation of sustained disruption can tighten inventories and amplify price volatility.
Humanitarian agencies warn of growing hunger
Aid organisations say that the most immediate human impact would be felt by vulnerable populations in countries already struggling with food insecurity. The UN and relief groups have flagged the potential for tens of millions more people to fall into hunger if food availability tightens and prices rise sharply. Emergency food assistance budgets would be stretched as donor countries and agencies contend with higher procurement costs and longer delivery times. The convergence of high debt burdens, currency weakness and import dependency in some states would undermine their ability to shield households from price shocks.
Economic and regional implications for Gulf economies
Gulf and regional economies are closely monitoring developments because disruptions in the Strait of Hormuz hit both trade flows and insurance and shipping costs in nearby waters. Ports, logistics hubs and maritime insurers could face higher operational burdens and premiums as risk assessments are updated. For countries in the Gulf and wider Middle East that are net importers of food or fertiliser-dependent, sharper price swings would affect domestic inflation and fiscal balances. Policymakers in the region may need to consider contingency measures, including stockpiling, alternative routing and support for vulnerable consumers.
Diplomatic and commercial mitigation options under consideration
Governments and commercial actors are exploring steps to reduce the risk of severe disruption to essential cargoes passing through the Strait of Hormuz. Options under discussion include diversifying shipping routes where possible, increasing regional transshipment capacity, accelerating port and rail alternatives, and negotiating temporary humanitarian corridors for agricultural inputs. Insurance firms and charterers are also studying risk-sharing mechanisms to keep shipments moving while protecting crew safety. Diplomacy aimed at de-escalation remains a central element in preventing a wider economic fallout.
Humanitarian and market responses will determine how quickly the immediate risk can be reduced, but the UN’s message underscores the narrow margin for error in global food systems. Rapid coordination between governments, international agencies, private shipping operators and manufacturers of agricultural inputs will be essential to prevent temporary maritime disruptions from becoming a prolonged food crisis.
