Iran conflict turns fertiliser chokepoint into Africa food security crisis

The Iran conflict has weaponised the Strait of Hormuz as a global food chokepoint, creating a systemic fertiliser supply shock that threatens catastrophic yield collapse across Africa just as critical planting seasons begin. Urea prices surged from $450-500 per tonne pre-conflict to over $700 by late April 2026, while the blockade halted 22 million tonnes of annual urea exports from the Persian Gulf—one-third of global seaborne trade, according to Anadolu Agency.

Sub-Saharan Africa imports 80% of its Fertiliser, creating acute vulnerability as the Persian Gulf supplies 49% of global urea exports and 30% of ammonia, per Alcott Global. The timing compounds the crisis: northern hemisphere planting seasons run April through May, precisely when stockpiles face maximum depletion. “The planting season is now. The fertilizer isn’t there,” said Raj Patel, food systems economist at the University of Texas, in an interview with PBS NewsHour.

Stockpile depletion timeline accelerates

Ethiopia derives over 90% of nitrogen fertiliser from Gulf suppliers routed through Djibouti, experiencing significant disruption even before the 28 February conflict outbreak. Bangladesh’s fertiliser reserves stood at 1.68 million metric tonnes as of late April, expected to last only until May-June 2026, with a 40,000-tonne DAP shipment from Saudi Arabia delayed by transit disruptions, according to the IFDC Fertilizer Crisis Response Bulletin.

FOB granular urea prices reached $800-900 per metric tonne by mid-April, up from $493 pre-conflict, with further upward pressure expected. Fitch Ratings raised 2026 ammonia and urea price expectations by approximately 25% due to conflict uncertainties, according to Anadolu Agency.

Yield collapse mechanics and food inflation cascade

The Food and Agriculture Organization estimates a 10% reduction in fertiliser availability could trigger up to 25% yield losses for maize, rice, and wheat across sub-Saharan Africa, potentially driving food inflation of 8% across the continent, per the African Development Bank. The shock hits hardest at smallholder farmers who produce nearly 70% of the region’s food but lack cash reserves to secure early supply or absorb price spikes.

Fertiliser accounts for up to 25% of agricultural commodity production costs, with a six-to-nine-month lag before price shocks reach FMCG and retail supply chains, according to Council on Foreign Relations. This creates a delayed compression wave: planting season shortfalls in May 2026 will materialise as food price spikes between November 2026 and February 2027, well beyond the current conflict timeline.

Oxford Economics raised Q2 2026 fertiliser price forecasts by 20% within days of the Hormuz closure. Wolfe Research estimates the disruption could raise US food-at-home inflation by approximately two percentage points, suggesting comparable or greater impacts across import-dependent African markets.

Corporate hedging signals persistent disruption

Major fertiliser producers are positioning for extended disruption. Yara International boosted shipments in Q1 2026 as conflict halted Hormuz transit, while Nutrien’s CEO sold shares worth approximately $5 million in March 2026 following the Iran conflict outbreak, according to Bloomberg. The executive share sales suggest industry leaders expect elevated prices to persist but are hedging personal exposure—a signal that confidence in sustained margins remains fragile despite near-term profit surges.

The fragile two-week ceasefire announced 12 April following talks in Islamabad offers limited relief. Supply chain restoration requires weeks of logistics coordination even if the Strait fully reopens, while producers prioritise higher-margin markets. Nigeria produces fertiliser domestically but exports the majority to Latin America rather than African markets, while Morocco controls over 50% of Africa’s phosphate supply but lacks sufficient nitrogen capacity to offset Gulf disruptions, per Rocky Mountain Institute.

Policy responses lag structural exposure

The African Development Bank’s Emergency Food Production Facility, launched in 2022 with $1.5 billion, has delivered 3.5 million metric tonnes of fertiliser to date, supporting 16 million smallholder farmers across 35 countries. While significant, this represents a fraction of total import volumes and cannot substitute for disrupted Gulf supply at scale. Regional governments face a narrow window to secure alternative supply before planting windows close, with limited fiscal capacity to subsidise price spikes or stockpile strategically.

What to watch

Monitor ceasefire durability beyond the initial two-week window and any signs of Hormuz transit resumption. Track Bangladesh and East African stockpile replenishment arrivals through May-June as the critical test of supply chain restoration speed. Watch for African government emergency procurement announcements and subsidy programmes, particularly in Ethiopia, Kenya, and Tanzania where planting season timing leaves minimal buffer. Corporate earnings calls from Nutrien, Yara, and CF Industries in May will reveal whether Q2 guidance reflects expectations of sustained disruption or near-term resolution. Food price indices for maize and wheat in sub-Saharan markets will provide early warning of the delayed inflation cascade beginning Q4 2026.
