191.3 million pounds of food every single day, and 70 percent moves through the Strait
At the narrow passage where the Persian Gulf meets the open sea, a geopolitical confrontation is quietly becoming a threat to something older and more urgent than energy markets: the daily bread of hundreds of millions of people. The Strait of Hormuz, long understood as an artery for oil, is equally a lifeline for food, water, and the fertilizers that sustain modern agriculture across continents. As Iran lays sea mines and the prospect of a sustained blockade grows less hypothetical, history reminds us that scarcity at the table has a way of reordering the political world — and that the most vulnerable always feel it first.
- Iran's mining of the Strait of Hormuz has transformed a theoretical risk into an active emergency, with only a handful of vessels now passing through a waterway that once carried 70% of the Gulf's food supply.
- A prolonged closure would demand a humanitarian airlift more than twelve times the entire daily capacity of the UN World Food Programme — a logistical feat the international community has never come close to achieving.
- The crisis would not stop at the Gulf's borders: disruptions to fertilizer and fuel flowing through the Strait would suppress crop yields from South Asia to Sub-Saharan Africa, driving up grocery bills in households far removed from the conflict.
- Attacks on desalination plants in Bahrain and Iran have introduced a second, faster-moving catastrophe — one that could leave millions without drinking water within days, with few technical alternatives and no margin for delay.
- Policymakers are being urged to treat this moment as a structural warning: the global food system, already strained by climate shocks and pandemic aftereffects, cannot absorb another cascading disruption without triggering widespread hunger and political unrest.
The Strait of Hormuz has long been understood as the world's most consequential oil chokepoint. But as Iran begins laying sea mines and the possibility of a sustained blockade moves from speculation to operational reality, the more immediate danger may not register in energy markets at all — it will arrive at dinner tables.
The six Gulf states — Bahrain, Kuwait, Qatar, the UAE, Saudi Arabia, and Iraq — are home to roughly 100 million people who depend on imports for nearly all of their food. About 70 percent of that food, some 191.3 million pounds per day, moves through the Strait. Replacing it by air would require more than twelve times the daily delivery capacity of the entire UN World Food Programme, routed through contested airspace. No precedent exists for an operation of that scale.
Iran would not escape the damage it risks inflicting. Already, bread and rent consume wages that no longer stretch far enough for many Iranians, and the mass protests earlier this year were partly born from that pressure. A blockade would tighten the squeeze on both sides of the waterway.
History is unambiguous about what food scarcity produces. The price spikes of 2008 triggered food riots across dozens of countries. The Russian drought of 2011 helped ignite the Arab Spring. Russia's invasion of Ukraine in 2022 sent grain and fertilizer prices surging again. The global food system is already under strain — it does not need another blow.
The consequences would extend well beyond the region. Between 30 and 40 percent of the world's traded nitrogen fertilizers pass through the Strait. When fertilizer and fuel grow expensive, farmers plant less and yields fall, and the cost travels the entire supply chain until it reaches households everywhere.
A separate, faster catastrophe is also taking shape. Attacks on desalination plants — already reported in both Bahrain and Iran — could deprive millions of drinking water within days. Unlike some infrastructure, desalination systems are complex, slow to repair, and have no ready substitutes. The margin for error is nonexistent.
For decades, international security in the Middle East has focused on preventing weapons of mass destruction. Yet a Strait closure could inflict civilian harm on a comparable scale by collapsing food, energy, and water systems simultaneously. All parties must act to prevent it — and policymakers everywhere must use this moment to address the deeper fragility of a global food system that is already far too close to the edge.
The Strait of Hormuz has become a chokepoint for something far more essential than oil. Where a hundred vessels once moved through daily, only a handful now slip past. Iran has begun laying sea mines in the narrow waterway, and the prospect of a sustained blockade—lasting weeks or months—is no longer theoretical. The immediate danger, though, will not show up in energy markets first. It will arrive at dinner tables across the world.
The Gulf region depends almost entirely on imported food. Bahrain, Kuwait, Qatar, the United Arab Emirates, Saudi Arabia, and Iraq together consume roughly 191.3 million pounds of food every single day, and about 70 percent of it moves through the Strait. These six countries have a combined population of roughly 100 million people. A prolonged closure would require an unprecedented humanitarian airlift to keep them fed—one that would dwarf anything the international community has managed before. The United Nations World Food Programme delivered an average of 15 million pounds of food per day to 81 million people across 71 countries in 2024. Meeting the Gulf's daily needs would require more than twelve times that capacity, and it would have to move through contested airspace.
The blockade would wound Iran as severely as its neighbors. The country would lose energy export revenue while watching the price of imported wheat, rice, animal feed, and cooking oil climb beyond reach. For many Iranians, basic necessities have already become unaffordable. Bread and rent consume wages that no longer stretch far enough. The mass protests that swept the country earlier this year were born partly from this squeeze. A blockade would tighten it further.
History offers a clear warning about what happens when food becomes scarce and expensive. In 2008, rising energy and fertilizer costs, combined with bad weather and policy failures, nearly doubled the price of staple crops. Food riots erupted in dozens of countries. Three years later, a severe drought and heatwave in Russia devastated grain harvests and pushed global food prices to record levels. The Arab Spring followed. When Russia invaded Ukraine in 2022, grain, fertilizer, and fuel prices spiked again, driving food insecurity upward across the world. The global food system is already under strain from climate shocks and pandemic aftereffects. It does not need another blow.
The consequences would ripple far beyond the Gulf. Farmers in South Asia, Sub-Saharan Africa, Europe, and the United States all depend on stable supplies of fertilizer and fuel. Natural gas is a key ingredient in nitrogen fertilizer, which has been central to modern agriculture and the historic crop yields we now take for granted. Between 30 and 40 percent of the world's traded nitrogen fertilizers pass through the Strait. When fertilizer and fuel become expensive, farmers respond by using less fertilizer or planting fewer acres. Yields fall. The cost gets passed along the supply chain—from farmers to truckers to food processors—until it reaches grocery bills in households everywhere.
There is another threat that could materialize within days rather than weeks. If the conflict contaminates the Gulf's waters or damages desalination plants, the consequences would be catastrophic. Last week, both Bahrain and Iran reported attacks on desalination facilities. If deliberate, such strikes would constitute war crimes under international law, as they would immediately threaten millions of lives. Unlike some critical infrastructure, desalination systems are highly complex and have few quick alternatives. Ukraine has shown that some systems can be repaired under fire, but the margin for error here is nonexistent.
For decades, international security efforts in the Middle East have centered on preventing weapons of mass destruction. Yet a closure of the Strait of Hormuz—whether through sea mines or sustained military conflict—could inflict civilian harm on a comparable scale by collapsing global food and energy systems and triggering a regional water crisis. All parties to the conflict and the broader international community must act to prevent this outcome. At the same time, this moment should serve as a wake-up call: the global food system is dangerously fragile. Policymakers must strengthen it now, before the next shock pushes millions more people toward the edge.

La Conversación del Hearth Otra perspectiva de la historia
Why does a blockade of an oil chokepoint matter so much for food? Isn't that mostly a fuel problem?
Oil is part of it, but the Strait moves far more than tankers. Wheat, corn, rice, soybeans, sugar, animal feed—all of it flows through there to the Gulf. And fertilizer and fuel flow out. You disrupt that, and you disrupt agriculture everywhere.
The Gulf countries have been preparing for this, though, right? Building reserves, investing in domestic production?
They have, and it's helped. But 70 percent of what they eat still comes through the Strait. You can't replace 191 million pounds of food a day through alternative routes. The math just doesn't work, especially if you're trying to move it by air.
What about the rest of the world? Why would farmers in Africa or the American Midwest care?
Because they depend on the same fertilizers and fuel that flow through the Strait. When those become scarce and expensive, farmers use less of them. Yields drop. That ripples through every supply chain until it hits your grocery bill.
You mentioned desalination plants being attacked. How immediate is that threat?
Immediate. If those plants go down, millions of people lose access to fresh water within days. Unlike some infrastructure, desalination systems are complex and can't be quickly replaced. It's a different kind of crisis than food, but it could be just as deadly.
Is there historical precedent for this kind of cascade?
Yes. Food price spikes have triggered political instability repeatedly—2008, 2010, 2011, 2022. When people can't afford bread, governments fall. The difference now is that the global food system is already strained from climate shocks and the pandemic. We're more fragile than we were.
