2026 US-Israel-Iran War Disrupts Global Grain and Food Supply Chains
Executive Summary
US-Israel airstrikes on Iran that began 28 February 2026 have escalated into open conflict, triggering Iranian disruption of the Strait of Hormuz. The chokepoint, which handles ~25% of global seaborne oil trade and 20-30% of fertilizer/ammonia/urea flows, now sees sharply reduced transit. This drives immediate energy and agricultural input shocks, with new analysis warning of tens of millions pushed into poverty in import-dependent Middle East, Africa, and Asia regions. Russia calls for BRICS food reserves while Ukraine ramps grain exports to Africa via Ghana.
First-order impacts: Crude oil (WTI/Brent) and natural gas spike on ~20-38% seaborne supply risk; fertilizer prices surge as Gulf sources (~30-49% of traded urea/ammonia) face scarcity. Energy and Materials sectors gain (magnitudes 4 and 3); Consumer Staples and Industrials weaken (magnitudes 3 and 2).
Second- and third-order effects: Higher input costs squeeze global grain planting and yields, elevating wheat prices and food inflation. North American processors face margin compression from elevated grain/feed costs, while alternative fertilizer routes strain logistics. Gold and safe-haven flows intensify amid broader risk-off sentiment; USD strengthens vs. EM currencies.
Relevant analogues include the 2019 Aramco Abqaiq attack (oil +15-20% intraday on 5% supply hit, quick recovery) and 2020 Soleimani strike (oil +3%, limited duration). This event breaks prior patterns through sustained Hormuz disruption and direct fertilizer linkage, amplifying food security transmission versus pure energy shocks.
Key uncertainties center on conflict duration, naval de-escalation success, and alternative shipping/fertilizer rerouting efficacy. Prolonged closure or expanded acreage shifts would intensify downside food impacts.
Key Risks
- Sustained Hormuz blockade drives oil above prior Aramco spike levels, triggering global stagflation and demand destruction in energy-intensive sectors.
- Fertilizer shortages reduce 2026/27 crop yields in Asia and Africa, spiking wheat and food prices with secondary poverty and migration shocks.
- Margin compression hits grain processors (ADM, BG down mag=3) and protein producers (TSN) from elevated feed costs and reduced farmer demand.
- Broader risk-off triggers EM currency weakness and equity selloffs in import-dependent regions.
- MOS margin squeeze from sulfur cost spikes (~44% Gulf seaborne exposure) despite phosphate gains.
Key Opportunities
- North American nitrogen and potash producers (CF mag=4, NTR mag=3, UAN mag=3) capture market share as Gulf alternatives amid ~30% urea/ammonia trade exposure.
- Major oil majors (XOM, CVX mag=3) benefit from structurally higher crude pricing on Hormuz risk.
- Alternative grain exporters and logistics hubs gain volume as Ukraine expands Africa routes and BRICS builds reserves.
- Gold and defensive commodities see safe-haven inflows.
Confidence
High confidence on first-order energy and fertilizer price transmission given confirmed Hormuz disruption and sector/ticker magnitudes; moderate on second-order food yield impacts due to planting season variability.
Event Background
The ongoing US-Israel-Iran war, which began with airstrikes on 28 February 2026, has disrupted the Strait of Hormuz, a critical chokepoint for global oil, gas, and fertilizer trade. This has triggered indirect shocks to grain exports, agricultural input costs, and food security, particularly in import-dependent regions in the Middle East, Africa, and Asia, with new research highlighting risks of pushing tens of millions into poverty. Responses include Russia's call for BRICS joint food reserves and Ukraine's expansion of grain exports to Africa via a new hub in Ghana.

Scenarios
| Name | Probability | Description | Key Trigger | Timeline Weeks |
|---|---|---|---|---|
| Prolonged Blockade and Escalation | 0.30 | The US-Iran naval confrontation intensifies with mutual attacks on shipping and energy infrastructure, keeping the Strait of Hormuz largely closed for months. Iran mines key areas and targets Gulf facilities while the US maintains a blockade of Iranian ports. Fertilizer and energy exports remain severely restricted, amplifying the causal chain of higher input costs, reduced global yields, and acute food shortages in import-dependent regions. | Renewed direct naval clashes or confirmed mining operations in the Strait of Hormuz with no immediate ceasefire talks. | 8 |
| Negotiated Ceasefire and Partial Reopening | 0.35 | Diplomatic efforts, potentially mediated by China or via backchannel US-Iran talks, lead to a limited ceasefire allowing selective safe passage for fertilizer and humanitarian shipments through the Strait. Energy flows resume partially while military tensions simmer. This eases some fertilizer export disruptions from Gulf producers but lingering energy price volatility constrains full agricultural recovery. | Public announcements of a temporary truce or UN-brokered safe-passage agreement for commercial vessels, especially fertilizer carriers. | 6 |
| Status Quo Muddling Through | 0.25 | Neither side achieves decisive control over the Strait; sporadic low-level incidents continue alongside selective toll-based or allied shipping. Russia expands grain exports and BRICS coordinates limited food reserves while alternative routes and stockpiles partially offset disruptions. Fertilizer prices remain elevated but farmers adapt through reduced application and acreage shifts without full crisis escalation. | Continued low-volume selective transits through the Strait without major new attacks or breakthroughs in talks, alongside rising BRICS/Russian food cooperation announcements. | 12 |
| Rapid De-escalation and Strait Reopening | 0.10 | A swift US-brokered or multilateral deal, possibly tied to Iranian regime stabilization post-leadership losses, results in full reopening of the Strait within weeks. Military operations wind down quickly. Gulf fertilizer and energy exports normalize, reversing much of the input cost surge and yield outlook deterioration. | Formal multi-party ceasefire agreement including explicit commitments to unrestricted commercial navigation in the Strait of Hormuz. | 4 |
