The Hidden Crisis

On the morning of 1 March 2026, for the first time in peacetime history, not a single oil tanker transited the Strait of Hormuz. The closure was instantaneous and complete. Within hours, oil prices began their climb toward $100 a barrel, then $120. Within days, every analyst in every major investment bank was running scenarios on energy markets, inflation, and interest rates.

Almost nobody was running the other scenario. The one that does not involve oil at all. The one that plays out not in the next quarter but in the next two years. The one measured not in dollars but in deaths.

It begins with a granule of white powder.

The Invisible Feedstock

Urea is the most widely used nitrogen fertiliser in the world. It is made from natural gas — converted under pressure with hydrogen into ammonia, then combined with carbon dioxide in a process discovered a century ago. It is unglamorous, bulk, and essential. Without nitrogen applied to soil, most of the world's staple crops cannot grow. This is not a metaphor. It is biochemistry.

The Gulf states — Qatar, Saudi Arabia, UAE, Kuwait, Bahrain, and Iran — collectively export roughly 22 million tonnes of urea per year. That is between 33 and 46 percent of all globally traded urea. They export a similar proportion of ammonia, and nearly half of all globally traded sulphur — itself a critical input in phosphate fertiliser production. All of it normally moves through the Strait of Hormuz.

Since 1 March, none of it has been moving. The price of urea has risen from roughly $482 per tonne on the eve of the war to approximately $700 per tonne by mid-March — a jump of nearly 50 percent in less than three weeks. That is faster than the price shock following Russia's invasion of Ukraine in 2022.

‘There's a lot of traded supply that is at risk,’ Dawid Heyl, a portfolio manager for global natural resources at Ninety One, told CNBC. ‘If farmers aren't able to get the urea that they need, crop yields will inevitably go lower.’ He estimates a 5 percent yield impact. Other analysts put the range at 5 to 15 percent. At 15 percent, with the existing humanitarian safety net stripped away, people starve.

The Clock That Is Already Running

The timing of this crisis is not random. It is catastrophically precise.

The Northern Hemisphere spring planting season runs from March through May. Wheat and corn go in the ground in those weeks. The window for applying nitrogen fertiliser is narrow — miss it, and you cannot recover the yield. Farmers across North Africa, South Asia, and the Middle East are attempting to purchase fertiliser that is either unavailable, unaffordable, or both.

Even if the Strait of Hormuz were to reopen tomorrow — which it will not — the planting season for hundreds of millions of acres is already compromised. Carnegie Endowment researchers warned in early March that restarting fertiliser production and transport could take weeks after any ceasefire: weeks that Northern Hemisphere farmers do not have.

318 Million People With Nowhere Left to Go

Before the first shot was fired, the World Food Programme estimated that 318 million people were already living at crisis-level hunger — IPC Phase 3, the threshold at which malnutrition becomes acute and death a routine statistical outcome. More than 40 countries were in this category.

These populations had no buffer. They were not households choosing between cuts of meat or managing rising costs. They were people already at subsistence, already dependent on aid organisations running on fumes, already in the shadow of famine.

Now add a 50 percent rise in urea prices. A 24 percent rise in ammonia. A sulphur market that was already structurally tight. And now remove the safety net.

The World Food Programme is funded at less than 35 percent of its requirements. UNCTAD reported that humanitarian aid shipments are now slower, more expensive, and less predictable as a direct consequence of the maritime shutdown. The system that caught people before they died is not there.

Where the Deaths Will Come

The geographic concentration of mortality risk is predictable. Sudan, Somalia, Ethiopia, the Democratic Republic of Congo, Niger, Mali, Yemen, Afghanistan, and Haiti face the highest absolute risk. Yemen is already in formal famine.

But the scale of exposure is not confined to the headline crisis zones. Bangladesh imports most of its nitrogen fertiliser. Pakistan's smallholder farmers depend on Gulf ammonia. Egypt — a country of 105 million people — imports more than 60 percent of its wheat and is heavily dependent on Gulf fertiliser. Egypt is not a country that appears on European lists of famine risk. It survived previous food crises partly because USAID was there to help buffer them.

The Market Has Not Priced This

Agricultural futures have moved. Oxford Economics has raised its forecast for global food price inflation in 2026 to roughly 2 percent. That is a market with some awareness of the problem. It is not a market that has priced in 33 to 46 percent of globally traded urea being off the market during the most critical agricultural window of the year. It is not a market that has modelled the 18-to-36-month mortality lag in 40-plus countries simultaneously.

Larry Fink, the chief executive of BlackRock, appeared on the BBC and described two extreme outcomes for this crisis. He did not mention the food chain. Almost nobody does.

A Slow Crisis in a Fast-Moving World

The Hormuz crisis has produced extraordinary images: burning tankers, grounded cruise ships, price boards flashing in red. Those images have concentrated minds in finance ministries. The food crisis has produced no images yet. It will. They will come from Sudan and Somalia and Yemen, and they will arrive 18 months from now when the diplomatic story has moved on and the news cycle has found other things to care about.

The fertiliser that was not shipped in March 2026 will not grow the crop that was not planted in April. The food that was not produced in 2026 will not feed the people who needed it in 2027. The deaths that come from that sequence of absences will come quietly, in the places that always absorb the world's failures quietly.
