Fertilizer Shock, Organic Pivots, and the Looming Hunger Emergency

The Fertilizer Institute reported that nearly 50% of global urea exports and about 30% of the world's ammonia originate from countries west of the Strait . With those flows disrupted, buyers in exposed markets faced not just higher prices but physical shortages. Analysis from the International Food Policy Research Institute shows that the closure effectively blocked approximately 21 million metric tons of annual urea export capacity from the Gulf region .

Goldman Sachs Research warns that these fertilizer cost increases will likely feed into grain prices, given that fertilizer accounts for roughly 20% of grain production costs . The supply shock is not just about what ships cannot leave the Persian Gulf; it is also about second-order effects. Fertilizer producers in India, Bangladesh, and Pakistan, deprived of natural gas feedstock from Qatar, have been forced to suspend or cut production .

The Global Scramble for Organic and Natural Alternatives

As chemical fertilizers became unaffordable or physically unavailable, farmers across three continents began pivoting to what they could source locally. An Associated Press report from late May 2026 captured this shift in vivid terms, documenting how farmers in Senegal, Brazil, and India are turning to manure, compost, and microbial biofertilizers to keep crops alive .

In Senegal, farmer Mamadou Sow had already made the switch to organic compost eight years earlier. Now, he is rallying neighbors to buy manure from local herders and teaching them how to build rich compost piles, checking for wriggling worms as a sign of health. "It's risky to depend on chemical fertilizers," Sow told the AP . Senegal, which imports roughly 125,000 tons of fertilizer annually, is now seeing a grassroots push toward on-farm nutrient cycling and biofertilizer production .

Brazil, the world's largest agricultural exporter, faces a uniquely perilous situation. The country relies heavily on imported fertilizers, and with Gulf supplies cut off, farmers are pivoting to bio-inputs and organic alternatives at a scale the sector has never attempted before . This is not a niche experiment; it is a structural response to the collapse of a supply chain that the Brazilian agricultural economy has depended on for decades.

India's exposure is equally severe. A Spanish defense ministry analysis estimates that India faces a 20% to 25% reduction in its fertilizer supply chain, with the flagship producer IFFCO at risk of suspending operations due to a potential 40% cut in LNG feedstock . With the critical kharif planting season for rice and maize approaching in June-July, smallholder farmers already operating on thin margins are being forced to reduce synthetic fertilizer application and substitute cow dung, compost, and domestically produced biofertilizers . The Economic Times notes that India is spending ₹1.86 lakh crore ($22 billion) on fertilizer subsidies while allocating just ₹2,481 crore to its National Mission on Natural Farming, a mismatch that the crisis has exposed .

Beyond the three focal countries, the push toward alternatives is visible globally. A Los Angeles Times report from May 2026 documents French startup Toopi Organics converting human urine into bacterial feed for crops, a Malaysian dairy producer feeding livestock waste to worms for soil enrichment, and researchers exploring ground almond shells and microbial products as synthetic fertilizer replacements . "The war situation is, sadly, a good thing for us," Toopi Organics' François Gérard told the paper . The crisis is accelerating investment in technologies that were previously considered marginal.

The Record Hunger Crisis Warning

The most alarming dimension of the Hormuz disruption is its humanitarian fallout. The World Food Programme has issued its starkest warning since the Ukraine war: nearly 45 million additional people could fall into acute food insecurity—IPC Phase 3 or higher—if the conflict persists through mid-2026 . This would push total global acute hunger to record levels, compounding the 318 million people already affected .

The mechanism is not mysterious. Higher fertilizer costs reduce yields. Reduced yields tighten food supplies. Tighter supplies, coupled with elevated fuel and transport costs, push food prices beyond what the most vulnerable populations can afford. UNCTAD warned in March 2026 that the drop in regional fertilizer exports threatens "extremely serious consequences" for global food production, with timing especially critical as sub-Saharan Africa enters its planting season .

WFP has already been forced to cut food rations for people in famine conditions in Sudan. In Afghanistan, the agency can now support only one in four acutely malnourished children—in what is currently the world's worst malnutrition crisis . Humanitarian shipping costs have risen 18% since the start of the conflict, and approximately 70,000 metric tons of WFP food supplies have been directly impacted by the disruption .

A Mercy Corps report published in late May 2026 projects that food insecurity will worsen for six highly exposed countries—Somalia, Sudan, Pakistan, Ethiopia, and others—through the second half of 2026 and into 2027 . The analysis notes that even after the April 7 ceasefire, the Strait has not returned to normal commercial operation. It remains under an Iranian permission-based transit regime, with mine hazard warnings still in effect, meaning fertilizer and fuel flows remain severely constrained .

The FAO Director-General has framed the stakes in generational terms: "The decisions we make now will determine whether this remains a manageable shock, or evolves into a deeper global food security crisis in 2026 and 2027, and beyond" . Crop planting cycles do not wait for diplomacy. When a farmer misses the window for adequate fertilization, the harvest is compromised, and the hunger that follows is measured in months, not weeks.

What Happens Next

Analysts at the University of Illinois have modeled three scenarios. Even under the most optimistic "quick reopening" path, urea stays above $700 per short ton through mid-2026 and only eases gradually . Under a contested transit scenario, prices remain elevated into November. Under extended conflict, the peak is not only higher but arrives later, at nearly $1,000 per ton in October . The duration of disruption matters as much as the initial shock.

The Carnegie Endowment notes that food prices typically take six to nine months to fully reflect a fertilizer supply shock, meaning the worst effects on consumer food inflation are still ahead . Meanwhile, China, India, and Egypt are among the countries most exposed to the disruption's prolonged effects on agricultural production .

What is clear from the evidence is that the Hormuz crisis is not just a trade disruption. It is a stress test of the global food system's resilience—and of the speed with which farmers and governments can adapt when the chemical inputs that underpin modern agriculture suddenly disappear.
