Strait of Hormuz Blockade: 2026 Fertilizer Crisis Explained

The 2026 Strait of Hormuz blockade has triggered a global fertilizer crisis that directly threatens the Northern Hemisphere planting season. Since February 28, Iran's closure of the strategic waterway has trapped approximately 16 million tonnes of annual fertilizer capacity, removing 35% of global seaborne urea and phosphate from the market. Urea prices at the Port of New Orleans jumped 30% in early March to $520–550 per tonne, and the UN Food and Agriculture Organization (FAO) has recorded 585 emergency policy actions across 146 countries as governments scramble to secure supplies.

What Is the Strait of Hormuz Blockade?

The Strait of Hormuz, a narrow waterway between Iran and Oman, handles nearly a third of global seaborne fertilizer trade. Before the 2026 Iran War, it had never been closed for an extended period despite repeated Iranian threats. The current blockade began after 'Operation Epic Fury,' when Iran closed the strait to Western-aligned shipping. Tanker traffic collapsed by over 90%, effectively severing a critical artery for Middle Eastern fertilizer exports. Gulf economies supply 24.8% of global nitrogenous and 11.4% of phosphatic fertilizer exports, making this closure a structural shock to the global fertilizer market.

Why Fertilizer Prices Are Surging

The disruption has produced immediate price shocks. According to the World Bank, urea prices have risen to their highest level since 2022, with the fertilizer index up 12% in the first quarter of 2026. Middle Eastern granular urea rose nearly 20% within a week of the closure, and by April some benchmarks had doubled from $400 to over $850 per tonne before easing. DAP prices climbed from $580 to $770 per tonne. The urea price surge reflects panic buying and export restrictions by major producers. China extended urea export restrictions and halted sulfuric acid exports, while Russia extended quotas and suspended ammonium nitrate export licenses. These moves compound scarcity and fuel further price increases.

Global Policy Response: FAO Records 585 Actions

In March 2026 alone, the FAO's Food and Agriculture Policy Decision Analysis (FAPDA) recorded 585 policy actions across 146 countries and territories—an unprecedented wave of emergency measures. Importers are prioritizing stabilization: India exempted ammonium nitrate from import taxes, South Korea banned urea hoarding, and Bangladesh bypassed the Strait via UAE agreements. Exporters, meanwhile, are restricting shipments to protect domestic markets. These measures mirror the playbook of past food security crises, but the scale is historic.

Impact on Food Supply and Vulnerable Countries

FAO Director-General QU Dongyu has warned that the fertilizer scarcity 'will lead to lower yields and tightening food supplies in the latter half of 2026 and into 2027.' Wheat, rice, and maize yields in the Northern Hemisphere are directly at risk. The most vulnerable countries include India, which sources nearly two-thirds of its nitrogenous fertilizer imports from the region; Thailand, which relies on the Gulf for about half; and Brazil, which is 85% import-dependent. Eighteen economies—including Kenya, Malawi, Mozambique, Rwanda, South Africa, Tanzania, Uganda, Zimbabwe, Nepal, and Sri Lanka—face acute supply disruptions. The compounding effect on agricultural supply chains could trigger a secondary wave of global food inflation, pushing millions more into crisis-level hunger.

Expert Perspectives

The global fertilizer scarcity caused by disruptions in the Strait of Hormuz will lead to lower yields and tightening food supplies in the latter half of 2026 and into 2027. — QU Dongyu, FAO Director-General.

Market analysts warn that if the strait remains closed, the world could face a structural supply failure reminiscent of the 1970s. The outcome depends on how quickly the Strait of Hormuz crisis is resolved and whether alternative routes can be scaled.

FAQ: Strait of Hormuz Blockade and Fertilizer Crisis

What is the Strait of Hormuz blockade?

The Strait of Hormuz blockade is Iran's closure of the strategic waterway to Western-aligned shipping since February 28, 2026, which has cut off a major route for Middle Eastern fertilizer, oil, and LNG exports.

Why are fertilizer prices surging in 2026?

Fertilizer prices are surging because the blockade has removed about 35% of global seaborne urea and phosphate from the market, triggering panic buying, export restrictions, and record policy interventions.

Which countries are most affected by the fertilizer crisis?

India, Thailand, Brazil, Pakistan, and many African nations are most affected, with India sourcing nearly two-thirds of its nitrogenous fertilizer imports from the Gulf region.

How is the FAO responding to the crisis?

The FAO is tracking emergency policy actions, coordinating international responses, and warning of severe food supply impacts if the blockade persists into 2027.

Will global food prices rise further?

Yes, experts expect food prices to rise as reduced fertilizer use lowers crop yields, with the FAO warning of tightening food supplies in late 2026 and 2027.

Conclusion

The Strait of Hormuz blockade is no longer just a geopolitical flashpoint—it is an unfolding agricultural emergency. With the Northern Hemisphere planting season already disrupted and policy responses stretched thin, the risk of a prolonged global food inflation cycle is rising. Reopening the strait remains the single most important step to restore fertilizer flows and avert a deeper hunger crisis.
