| Driver | Impact |
|---|---|
| China phosphate export ban | China restricted phosphate exports through August 2026, removing ~30% of global trade volume — the single largest price driver. |
| Morocco and Saudi supply | Alternative suppliers (OCP, SABIC) run at capacity but cannot fully offset China volumes. |
| Ammonia input costs | DAP production requires ammonia; elevated natural gas costs raise the cost floor. |
| Spring demand surge | Concentrated spring application demand amplifies price spikes during March–May. |
