# Fertilizer prices surge amid Iran war, sparking food security warnings

> Fertiliser prices have surged as the Iran war constricts supply through the Strait of Hormuz, which carries about one-third of seaborne fertiliser trade. Ships have been hit and traffic has largely halted since the conflict began on February 28. Food insecurity warnings are growing ahead of Northern Hemisphere spring planting.

## Why it matters

Higher fertiliser costs during spring application raise grower input costs and may shift acreage away from nitrogen-intensive corn, influencing feed grain supply and prices.

| DAP | 2026-03-26 | 1 | +5.5% | 10.0 | Hormuz disruption since Feb 28 constrains about one-third of seaborne fertilizer trade, and the 2026-03-25 surge in fertilizer prices and food security warnings plausibly fed a sharp one-day DAP jump through supply and sentiment. |
