A looming global food price surge is taking shape as fertiliser shortages, linked to disruptions from the Iran conflict, begin to ripple through agricultural supply chains, according to the Grosvenor Group.
The warning, issued by senior leadership within the firm owned by Hugh Grosvenor, points to a sharp rise in fertiliser costs, with prices reportedly increasing by between 50% and 70% since the escalation of tensions in the Middle East earlier this year.
Fertiliser is a critical input for modern agriculture, directly influencing crop yields and food production efficiency. When prices spike, farmers face higher operating costs, which are often passed on through the supply chain, ultimately affecting consumer food prices.
According to the company, the full impact of the war is likely to be felt next year, as planting cycles and production timelines mean current cost increases will translate into reduced output or higher prices in future harvests.
The effect is closely tied to disruptions in global energy markets, particularly involving the strategically vital Strait of Hormuz. The ongoing conflict involving Iran has affected the flow of oil and gas, key components in fertiliser production, especially nitrogen-based fertilisers which rely heavily on natural gas.
As energy prices rise, fertiliser manufacturers face increased production costs, leading to reduced supply and higher market prices. This creates a cascading effect across the global food system, from farm inputs to retail prices.
Industry analysts warn that the situation could disproportionately affect developing regions, including parts of Africa, where farmers are already grappling with limited access to inputs and financing. Higher fertiliser costs may force some farmers to reduce usage, potentially lowering yields and exacerbating food insecurity.
The warning from Grosvenor Group adds to growing concerns about the broader economic consequences of geopolitical instability. While much attention has focused on oil prices and energy markets, the secondary effects on agriculture and food systems are now becoming clearer.
Experts note that fertiliser markets are particularly sensitive to global shocks because production is concentrated in a few regions, and supply chains are tightly linked to energy availability. Any disruption can quickly lead to shortages and price volatility.
The situation also highlights the interconnected nature of global systems. A conflict in one region can trigger consequences far beyond its immediate geographic scope, affecting everything from energy costs to supermarket prices thousands of miles away.
For farmers, the challenge is immediate. Higher input costs squeeze profit margins and increase financial risk, particularly for smaller producers. Some may delay planting, switch crops, or reduce fertiliser application—all of which can impact overall food supply.
Consumers, meanwhile, are likely to feel the effects later, as higher production costs work their way through the supply chain. This could lead to increased prices for staple foods, adding pressure to household budgets already strained by inflation.
Policymakers are expected to monitor the situation closely, with potential interventions including subsidies, strategic reserves, or efforts to stabilise supply chains. However, the effectiveness of such measures will depend on how long the underlying geopolitical tensions persist.
The warning is clear: the impact of the Iran conflict is not confined to energy markets. It is beginning to reshape the economics of food production, with consequences that could be felt globally in the months ahead.
