The Iran war is turning food inflation into a shipping problem, then into a farm-input problem, and farmers are already reacting. With the strait of Hormuz effectively shut, supplies of fuel and fertiliser are tightening and prices are jumping, pushing growers to hoard what they can and, in some cases, consider planting less. In India and Sri Lanka, that anxiety is showing up ahead of the crucial kharif rice season, when a missed fertiliser window can turn into a weaker harvest months later.
The early macro signal is visible in the data. The UN Food and Agriculture Organization’s food commodity gauge averaged 128.5 points in March, up from February, with higher energy and freight costs rippling through supply chains. The Guardian’s summary of the same report puts the rise at 2.4 percent in March, with vegetable oil up 5 percent and sugar up 7 percent. Even the relatively abstract notion of “freight costs” has teeth here: fertiliser, grain, and fuel are all bulky, transport-heavy inputs, so higher shipping and insurance bills land quickly in food prices.
On the ground, the constraint is less about headline grain supplies and more about the chemistry and energy that make high yields possible. India, the world’s second-largest fertiliser consumer, relies heavily on imports routed through Hormuz, and domestic urea production depends on natural gas that is now scarcer; one report notes gas supplies to fertiliser factories have been cut by 30 percent. Farmers and retailers describe panic-buying and price spikes, while officials insist buffer stocks are adequate and sourcing is being diversified. That leaves a stark near-term tradeoff: governments can try to cap prices and ration supply, but if fertiliser does not reach farms on time, the bill shows up later as lower output, tighter rice stocks, and a new round of consumer inflation.
