Hormuz Closure Raises Fears of Global Grain Disruptions

The potential closure of the Strait of Hormuz amid escalating conflict involving Iran is raising concerns over a possible disruption in global grain supplies, with analysts warning that prolonged instability could trigger higher food prices and renewed inflationary pressure worldwide.

The strategic waterway, best known as a vital route for global oil shipments, also plays a significant role in international grain trade. If maritime traffic remains restricted, supply chains for wheat, corn, and animal feed could face serious disruptions, according to market analysts and shipping data.

Among regional economies, Iran appears to be the most vulnerable to the disruption. The country relies heavily on grain imports to meet domestic demand, particularly for corn used in animal feed.

Data from maritime analytics firm Kpler indicates that a large share of Iran’s grain imports typically arrives through shipping routes that pass the Strait of Hormuz. Any prolonged interruption in traffic could therefore create significant food supply pressures and rising inflation within the country.

Iran currently imports roughly 30% of its wheat consumption, while nearly all of its corn supply is imported, mainly from Brazil. Analysts warn that shortages in animal feed and rising food prices were already pressing issues before the conflict escalated, and could worsen in the coming weeks if supply disruptions persist.

Although Iran imports some grain from Russia, the majority of those shipments still rely on maritime routes connected to the Gulf. One potential alternative could be imports through northern ports on the Caspian Sea, which may serve as a limited lifeline if southern routes remain blocked.

The timing of the conflict also coincides with Iran’s agricultural cycle. Harvesting of barley and wheat is expected to begin within weeks, followed by the corn harvest around July, which could temporarily help ease domestic supply pressures.

In contrast, Saudi Arabia and the United Arab Emirates may face logistical challenges but are less exposed to severe supply disruptions due to alternative port access outside the Gulf.

Saudi Arabia can continue importing grains through Red Sea ports, including Jeddah Islamic Port and King Abdullah Port, bypassing the Strait of Hormuz entirely. According to shipping data, the kingdom also holds wheat reserves sufficient for at least six months of domestic consumption.

The UAE, meanwhile, has the option of importing grains through Fujairah Port, which lies outside the Strait of Hormuz, while also drawing on national grain reserves if the conflict continues.

Although both countries could still experience slower trade flows and higher shipping costs, analysts say they remain better integrated into global supply networks than Iran, reducing the risk of severe shortages.

Beyond the region, economists warn that the conflict could have broader consequences for global food markets.

Research from S&P Global Commodity Insights suggests that escalating tensions in the Middle East could increase the risk of food inflation by driving up fuel, fertilizer, and shipping costs, three critical inputs for global agricultural supply chains.

Similarly, analysts at ING Global Markets say the conflict could trigger a wider supply shock if it persists, citing rising energy prices, logistical disruptions, and increasing geopolitical risk premiums across commodity markets.

“The geopolitical risk premium is now deeply embedded in the relationship between food, energy, and shipping,” ING analysts noted, warning that food price inflation could intensify throughout 2026, particularly in import-dependent and economically vulnerable countries.

With roughly one-fifth of global energy flows and significant volumes of maritime trade passing through the Strait of Hormuz, any prolonged disruption threatens to ripple across global markets, from energy and shipping to food security and consumer prices.
