Iran War Is Crushing Asia's Farmers, and Your Grocery Bill Is Next
Here's something that doesn't make the evening news: a 60-year-old rice farmer in Thailand's Chachoengsao province, a man named Suchart Piamsomboon, has decided to stop farming. Not because he wants to. Because the math has become impossible. Fertilizer that used to cost 800 baht a sack now costs over 1,100, if it arrives at all. He'll work as a day laborer now, scraping together 100 to 200 baht a day, just to survive.
Suchart is far from alone. Four thousand miles from the missile strikes and naval standoffs in the Middle East, a quiet catastrophe is unfolding across Asia's rice paddies and wheat fields. The Iran war, the one you might be tracking for oil prices, is also breaking the global food supply chain. And the consequences? They're headed for dinner tables everywhere, from Manila to Manchester, from Jakarta to Johannesburg.
Let me walk you through what's happening, in plain language, with the human stories behind the numbers.
1. A War 4,000 Miles Away Hits Home in Thailand's Rice Fields
When the United States and Israel struck Iran on 28 February 2026, the immediate headlines were about oil prices and military escalation. Fair enough. But something else happened almost instantly, and it's arguably more consequential for the 4 billion people across Asia.
The Strait of Hormuz, that narrow strip of water between Iran and Oman through which roughly one-third of the world's seaborne fertilizer and one-quarter of its seaborne oil normally pass, effectively shut down. Major shipping lines like Hapag-Lloyd and Maersk suspended all transits, rerouting vessels around Africa's Cape of Good Hope, a detour that adds thousands of miles and 10-15 days to each trip.
It sounds like a logistics problem. In reality, it's the pin that popped the global food bubble.
Within weeks, urea, the most widely used nitrogen fertilizer on the planet, jumped in price by more than 40%. Diesel, the lifeblood of irrigation pumps and tractors, surged alongside it. For farmers in Thailand, Vietnam, Cambodia, the Philippines, and India who were about to begin their planting seasons, the timing could not have been worse.
And then China, the world's biggest fertilizer producer, made everything much harder.
2. Why a Strip of Water Called Hormuz Matters More Than You Think
To understand why a waterway most people couldn't find on a map is causing hunger alerts, you need to grasp one uncomfortable truth: modern agriculture runs on fossil fuels. Since the Green Revolution, the high-yield crop varieties that feed billions require massive inputs of industrial fertilizer, particularly nitrogen fertilizers like urea, which are made from natural gas.
The Persian Gulf is not just an oil hub; it's a fertilizer superpower. Consider these numbers:
- The Middle East supplies nearly 30% of global ammonia exports , and ammonia goes into about 70% of all fertilizer produced worldwide.
- Just three countries, Saudi Arabia, Oman, and Qatar, supply over three-quarters of India's ammonia imports.
- Asia normally takes 35% of the Gulf's urea exports, 53% of its sulphur, and 64% of its ammonia.
- About 80% of the oil and oil products passing through Hormuz go to Asia, along with nearly 90% of the LNG.
Think of the Strait of Hormuz as the highway connecting the world's fertilizer factory to Asia's farmlands. When that highway closes, the factory can't deliver. And crops can't grow.
2a. The Fertilizer Gate Is Shut
When Hormuz closed, global fertilizer prices surged 26.2% in a single month (March 2026), while food prices rose 2.7%. The UN's Food and Agriculture Organization (FAO) warned that if the crisis persists, fertilizer prices could average 15% to 20% higher in the first half of 2026 than previously projected.
This isn't abstract. In Thailand, fertiliser that cost 850 baht per bag now runs 1,000 to 1,200 baht, a nearly 50% jump that forces farmers to halve their application rates. In the Philippines, where rice planting depends on imported inputs, farmers are staring at fields they can't afford to sow.
And then came the second punch.
2b. Then China Locked Its Own Doors
China produces roughly 25% of the world's fertilizer and exported more than $13 billion worth of it last year. In March 2026, Beijing banned exports of several crucial fertilizer types, including urea and diammonium phosphate (DAP), to prioritize domestic food security. Between half and 80% of China's fertilizer exports are now restricted, according to analysis of Chinese customs data.
The logic is understandable. The impact is devastating. A Chinese fertilizer exporter, speaking anonymously, described contracts signed and shipping dates confirmed "to at least five or six countries", Thailand, Indonesia, New Zealand among them, that now cannot be fulfilled. "The clients were waiting," he said. "But now we have been told not to ship."
As Joseph Glauber of the International Food Policy Research Institute put it: "The combined effect of China's export ban and the closure of the Strait of Hormuz will inevitably rattle the global fertiliser market and food security."
3. From Empty Shelves to Empty Plates: The Farmer's Impossible Math
Here's where the crisis becomes human.
3a. When Planting Becomes a Losing Bet
In Thailand's Chai Nat province, a 60-year-old farmer named Sripai Kaew-Eam has done what millions of others are doing: she's cutting her losses. Production costs have jumped from 4,500-5,000 baht per rai (0.4 acres) to about 6,000 baht, while the price she gets for unhusked rice hovers around 6,200 baht per ton. The margin has essentially vanished.
So she halved her fertilizer use. That means lower yields. That means less rice entering the global market. Multiply this decision across hundreds of thousands of smallholder farmers across Southeast Asia, and you begin to see the scale of what's coming.
"Farming only leads to financial losses," said Suchart Piamsomboon, the farmer from Chachoengsao who gave up entirely. "I'd rather work as a day labourer and earn 100 to 200 baht a day just to get by."
When farmers stop farming, everyone eats less. It really is that simple.
3b. India's DAP Crisis, And the Black Market That Followed
India tells a parallel but distinct story. When Israel and Iran clashed for 12 days in June 2025, a preview of the larger 2026 war, it disrupted shipments of rock phosphate and phosphoric acid, the raw materials for diammonium phosphate (DAP), the fertilizer Indian farmers rely on during the crucial Kharif sowing season.
Then, in June 2025, China stopped exporting DAP, partly to secure its own food supply, partly to redirect phosphates into electric vehicle battery manufacturing.
The result? Long queues outside fertilizer shops, empty shelves, and black-market premiums in rural Maharashtra. One Indian farmer, Dheeraj Pandey, wasn't watching war updates, he was watching his farm fail as the shelves stayed empty.
India's vulnerability underscores a structural reality: the country imports roughly 95% of its specialty fertilizers, including phosphates, primarily from China. When geopolitics disrupts supply, there is no quick fix.
4. The Shipping Nightmare No One Is Talking About
Beyond fertilizer, the physical movement of existing grain is under siege.
The Strait of Hormuz closure didn't just stop inputs from getting in. It stranded vital shipments of rice, wheat, and barley destined for the Gulf region and beyond. CMA CGM, one of the world's largest shipping carriers, suspended all passages through the Suez Canal, rerouting vessels around Africa, adding 10-15 days of transit time and massive cost increases for shipments from the Black Sea and Mediterranean to Asia.
A Singapore-based trader at a leading global rice merchant described the situation bluntly: "Logistics have become a nightmare, especially in Asia as there is a shortage of polypropylene bags, limited truck availability to move rice to ports and shipping itself has been disrupted."
And there are compounding crises: the Ukraine-Russia war continues to threaten Black Sea grain corridors. El Niño is expected to bring hotter, drier weather to Southeast Asia in the second half of 2026, further squeezing rice production.
It's what analysts are calling an "everything crisis", fuel, fertilizer, freight, and weather all hitting at once.
5. What Happens When Asia's Rice Bowl Runs Low
The projections are sobering.
The UN World Food Programme estimates that nearly 45 million more people could face acute food shortages if the Iran conflict continues into mid-2026 and oil prices remain above $100 per barrel. In Asia and the Pacific specifically, food insecurity is expected to rise by 24% , the largest relative increase of any region on earth.
Rice, the staple food for over half of humanity, sits at the center of this storm. The FAO had forecast a 2% increase in global rice production for 2025/26, reaching a record level. But those projections were made before the Hormuz closure. Farmers are now cutting planting acreage, reducing input use, and in many cases, abandoning fields entirely.
Maximo Torero, the FAO's chief economist, put it plainly: "Farmers have already started planting rice in some countries and are using fewer inputs because prices have gone up. We are going to see a tighter global supply situation in the second half of the year and early next year."
If this sounds familiar, it should. In 2008, export restrictions by major rice suppliers more than doubled prices to about $1,000 per metric ton, triggering food riots across multiple countries. More recently, India's 2022-2023 export restrictions, triggered by domestic supply concerns, lifted global prices and caused panic buying in import-dependent nations.
The difference this time? The supply shock isn't coming from just one country's policy choice. It's coming from a chokepoint 4,000 miles away that no Asian rice farmer can control.
6. Is There a Way Out? Solutions, Workarounds, and Hard Truths
If there's a glimmer of hope, it's that the world is not powerless here , but the window for meaningful action is narrowing.
In the short term, the FAO and other international bodies are urging:
- Development of alternative trade routes to bypass Hormuz, though this is far easier said than done given the geography.
- Financial support programs for farmers to help them afford inputs during the crisis.
- Targeted food aid for the most vulnerable import-dependent countries, particularly those in South Asia and East Africa.
In the medium term, boosting regional fertilizer production within Asia is the most obvious response. However, production plants in Pakistan, Bangladesh, and India are themselves scaling back or shutting down due to surging energy costs.
In the long term, the crisis has exposed a structural vulnerability that policymakers have acknowledged for decades but done little to address: Asia's profound dependence on Middle Eastern energy and fertilizer. Diversifying energy sources, particularly through renewables, and investing in domestic fertilizer production capacity (including biofertilizers) must become strategic priorities rather than afterthoughts.
Malaysia has expanded fuel subsidies to cushion its farmers. Some Southeast Asian nations are exploring alternative suppliers in Canada, Russia, and elsewhere, though Russia, too, is an unreliable partner given its own war and export restrictions.
The hard truth: most of these are bandaids, not solutions. The only real fix, reopening the Strait of Hormuz, depends on a diplomatic resolution that remains uncertain.
But awareness is the first step. This crisis has been called "quiet" and "hidden", because the farmers suffering most have the smallest voices. They deserve better.
