Hormuz Shock Forces Rethink Of Global Grain, Fertiliser And Shipping Routes

While headlines focus on oil and LNG, the near‑closure of the Strait of Hormuz is quietly creating a secondary crisis in global agriculture, fertiliser supply and food logistics that could push up prices far beyond the energy complex.

More than 80% of world trade moves by sea, and the Gulf’s key chokepoint is not only a conduit for hydrocarbons but also for shipping traffic that underpins global food systems. Al Jazeera notes that the Iranian attacks and de facto blockade have already forced Gulf producers to halt shipments amounting to up to 140 million barrels of oil – around 1.4 days of global consumption – and that rapidly filling storage has compelled some oilfields in Iraq and Kuwait to cut production, with the UAE expected to follow.​

Those production cuts, and the spike in bunker fuel and insurance costs, filter directly into the cost of moving grains, oilseeds, meat and fertiliser. Freight rates have surged to “unprecedented levels,” Reuters reports, as hundreds of tankers and carriers remain stuck near Hormuz and rerouted vessels face longer journeys and higher risk surcharges. For agricultural exporters in the Americas, Europe, Australia and the Black Sea, that means higher delivered prices; for import‑dependent regions in North Africa, the Middle East and parts of Asia, it means tighter margins and potential shortages.

Fertiliser is a particular concern. Natural gas is a key feedstock for nitrogen fertilisers, and disruptions in Gulf gas supply – especially from Qatar – are driving up input costs for fertiliser producers elsewhere. If high prices reduce application rates in the coming planting seasons, yields could suffer, amplifying the impact of shipping disruptions and weather volatility.

Governments and commodity houses are scrambling to adjust. Some Asian buyers are exploring alternative ports and longer routes that avoid Hormuz, though these add time and cost. Strategic food and fertiliser stockpiles are being reviewed, and emergency tenders may become more common if prices continue to rise into the second half of the year.

The World Bank and other institutions warn that extended disruption could reverse some of the progress made on global food‑price stability since the peaks of 2022. For lower‑income countries that spend a large share of export earnings on food and fuel, the combination of higher energy and shipping costs is particularly dangerous.​

Policymakers now face a series of uncomfortable trade‑offs: whether to subsidise domestic fuel and food to soften the blow, at the cost of higher deficits; whether to impose price controls or export restrictions that might destabilise markets further; and how to target limited support to the most vulnerable populations.

As with energy, the key unknown is duration. If naval escorts and diplomatic pressure can reopen Hormuz within weeks, the shock may show up mainly as a sharp but temporary spike. If, as intelligence sources cited by Reuters suggest, Iran can sustain drone and missile attacks for months, the agricultural fallout – via fertiliser, freight and insurance – could become one of the defining economic stories of 2026.
