The conflict in Iran has paralyzed shipping through the Strait of Hormuz, a chokepoint for nearly a third of the world's seaborne fertilizer trade, leading to sharp price increases and raising alarms over global food security.
Disruption in the Strait of Hormuz
The Strait of Hormuz, along Iran's southern coast, is vital for international trade. According to the UN, approximately one-third of global seaborne fertilizer shipments transit this waterway. Since the U.S. and Israel initiated strikes on Iran on February 28, 2026, maritime traffic has effectively ceased, with several vessels targeted by projectiles in or near the strait.
Soaring Fertilizer Prices
Analysts report dramatic price hikes for key fertilizers:
- Urea (a nitrogen fertilizer) surged to around $700 per metric ton, up from $400-$490 pre-war.
- Ammonia prices increased by about 20%.
- Urea prices rose by approximately 50%.
- Other fertilizers, including potash and sulfur, have also seen price increases.
Oxford Economics' Alpine Macro noted these surges in a recent report.
Expert Warnings on Supply Chain Impact
Chris Lawson, VP at CRU, estimates that about 30% of exportable fertilizer supplies from Middle Eastern countries—including Saudi Arabia, Qatar, Bahrain, and Iran—are currently unavailable. Iran is a leading global exporter of nitrogen-based fertilizers.
Dawid Heyl, co-portfolio manager at Ninety One, emphasized the critical role of nitrogen: "You can't skip a season of nitrogen." He expressed greater concern than during the Russia-Ukraine war, citing the broader impact on agricultural yields.
Sarah Marlow of Argus highlighted that the region accounts for nearly 50% of global sulfur trade, around 33% of urea, and close to 25% of ammonia. She stated the crisis is "more significant" than the Ukraine conflict due to affecting multiple producers.
Food Security Concerns
Heyl noted that while buffer stocks of food commodities exist, prolonged supply issues could lead to food inflation. Emerging markets, such as India and nations in East Africa, are particularly vulnerable due to reliance on imports and limited ability to absorb price shocks. The U.S., though more self-sufficient in nitrogen fertilizer, is not entirely immune.
Additional Factors Exacerbating the Crisis
- QatarEnergy has halted downstream urea production following a suspension of liquefied natural gas operations.
- China has imposed export restrictions on fertilizers to safeguard its domestic supply, as reported by Reuters.
