▾ assumptions
  • March 1st the Strait of Hormuz was closed due to the war with Iran.
  • ~32.5% of global urea production (~190M tonnes/year) transits the strait, primarily from Qatar, Saudi Arabia, UAE, and Iran.
  • ~20% of global phosphate production (~237M tonnes/year) originates from the region, driven by Saudi Arabia.
  • ~45% of the world's traded sulfur (~75M tonnes/year) passes through the strait, a key input for phosphate fertilizers.
