The UN's Food and Agriculture Organization warned Wednesday that a prolonged Hormuz closure could "turn into a global agrifood catastrophe" — the agency's sharpest language since the blockade began [1].

The warning centers on fertilizer, not oil. Roughly 30% of the world's traded fertilizer — urea, ammonia, potash — passes through the strait [1]. Fields that do not receive spring applications will yield less come autumn. That consequence cannot be reversed by a June ceasefire.

Fuel oil prices rose 30.7% in March alone, compressing margins for shipping lines already avoiding Persian Gulf routes [1]. Freight costs for vessels rerouting around the Cape of Good Hope have added $1 million or more per voyage on Asia-Europe lanes. Those costs reach farmers as input inflation before the season is out.

The FAO drew an explicit parallel to 2008, when fertilizer and oil spiked simultaneously and food riots erupted across 30 countries. The difference this time: the shock is supply-side, not price-driven. Fertilizer that cannot be shipped is not fertilizer that is merely expensive.

Sub-Saharan Africa and South Asia are most exposed. Both regions depend heavily on imported nitrogen fertilizers and have limited domestic buffer stocks. Yemen, Somalia, and Sudan — already in acute food emergency — have no contingency margin.

The agency called for immediate humanitarian exemptions to allow fertilizer shipments through disputed corridors. No such exemption has been agreed.
