# Fertilizer Prices Have ‘Significant’ Rise After Attack on Iran

> The US-Israel military conflict with Iran has closed the Strait of Hormuz, which normally carries about 20% of global oil demand and roughly a quarter of traded nitrogen fertilizer. Diesel futures hit a two-year high, and New Orleans urea barges traded $520-550/ton, up from $475. Phosphate prices also rose about $30/ton.

## Why it matters

Strait closure disrupts fertilizer and energy flows, raising farm fuel and nitrogen costs and supporting feed grain prices through higher input costs and tighter supply.

| UREA | 2026-04-01 | 1 | +8.4% | 3.0 | Dated on the move day, it reports the Strait of Hormuz closure, which cuts a quarter of traded nitrogen fertilizer supply and sent New Orleans urea barges up from $475 to $520-550/ton, directly explaining the 8.43% jump. |
| DAP | 2026-04-06 | 1 | +3.2% | 3.5 | Hormuz closure from the Iran conflict lifted fertilizer and energy prices, with phosphate up about $30/ton, a supply and input-cost shock that plausibly drove DAP higher. |
