From Missiles to Meal Prices: How the Iran-Israel-US Conflict Is Driving Global Food Inflation
Food prices were already elevated going into 2026. Three years of supply chain disruption, two years of drought across the Sahel and the Horn of Africa, and the lingering effects of Russia's 2022 blockade of Ukrainian grain exports had left global food systems unusually vulnerable. The Strait of Hormuz closure has now delivered a compounding shock that is, in the assessment of several leading agricultural economists, potentially more damaging to food security than anything since the 2007–2008 food crisis.
The mechanism is not simple or direct — it is a chain of interconnected pressures that flows from a closed strait through fertiliser markets, diesel prices, and shipping costs, eventually arriving at the price of bread, maize flour, and cooking oil in markets across the developing world. Understanding that chain is essential to understanding the true stakes of the current crisis.
The Fertiliser Transmission Mechanism
The most immediate food-related impact of the Hormuz closure is on fertiliser supply and pricing. The Persian Gulf region is one of the world's largest producers and exporters of nitrogen-based fertilisers — particularly urea and ammonium nitrate — produced from the region's abundant natural gas. Qatar, Saudi Arabia, and the UAE together account for a significant share of global urea exports, and virtually all of their maritime exports pass through the Strait of Hormuz.
Urea prices at the New Orleans hub — the benchmark for North American agricultural markets — have risen from $475 per metric ton at the start of February to $680 as of mid-March, a 43% increase in six weeks. In Brazil, the world's largest importer of nitrogen fertilisers, urea has risen even more sharply in local currency terms as the real depreciates against the dollar under broader emerging-market pressure.
The timing could hardly be worse. March and April are the key application window for corn, soya, and spring wheat in the Northern Hemisphere. Farmers who cannot afford fertiliser at current prices, or who cannot source it in time, will either reduce planted acreage or under-apply, with direct consequences for yields. The USDA's initial estimate, published on March 14, suggests U.S. corn planted acreage could fall by 4–6% from 2025 levels if fertiliser prices remain elevated through April — a reduction that, in a world with limited grain reserves, is material to global food security.
The Diesel Effect
Every stage of the food production and distribution system runs on diesel. Tractors, combine harvesters, irrigation pumps, grain dryers, refrigerated trucks, and container ships all consume petroleum products. When crude oil prices rise by 40%, diesel prices follow — and every step in the food supply chain becomes more expensive simultaneously.
The FAO estimates that for every 10% increase in global energy prices, food production costs in developing nations rise by approximately 3–5%, with the pass-through to consumer prices typically occurring over a three-to-six month lag. The current energy price spike — oil up more than 40% from pre-crisis levels — implies a food production cost increase of between 12 and 20%, with consumer price effects landing in supermarkets and markets from June onwards.
Shipping and the Cold Chain
The closure of both the Strait of Hormuz and the Red Sea has forced global container shipping onto the Cape of Good Hope route, adding 10–14 days and enormous additional cost to voyages between Asia, the Middle East, and Europe. For temperature-sensitive agricultural products — fresh produce, frozen meat, dairy — those extra days in transit have direct quality and safety implications. Exporters of perishables from Southeast Asia and South America to Middle Eastern and European markets are facing a choice between absorbing massive additional freight costs and watching their products spoil in transit.
Who Bears the Cost
As with the energy shock more broadly, the food price impact is radically unequal. Wealthy nations will see food inflation — uncomfortable, politically significant, but manageable within existing social safety nets. Middle-income developing nations, many of which spend 20–40% of household income on food, will see a direct and painful reduction in living standards. The most vulnerable nations — those in sub-Saharan Africa and South Asia that are heavily import-dependent, have minimal foreign currency reserves, and lack functioning social safety net infrastructure — face the prospect of acute food insecurity affecting tens of millions of people.
The World Food Programme has issued an emergency appeal for additional funding, warning that its existing programmes — already stretched by multiple concurrent crises — are now insufficient to meet anticipated needs in the second and third quarters of 2026. The FAO's food price index, which had been declining gradually through 2025, is already back at levels last seen during the 2022 peak. If the Hormuz closure persists for more than two months, the index is projected to exceed that peak — which itself triggered food riots in more than thirty countries.
The Longer Shadow
The full food price impact of the current crisis will not be visible for months. Commodity markets are pricing future harvests now, and the signals they are sending — high fertiliser prices, elevated diesel costs, freight disruption during the planting season — point to lower yields and higher prices in the second half of 2026 and into 2027. The crisis that started with missiles and maritime closure is writing itself into next year's food prices, today.
