Here’s a simple market story: something happens in a faraway place, and suddenly a bunch of stocks you might not think about every day go bananas. Right now, that something is a conflict involving Iran, and those stocks are fertilizer companies. Shares of CF Industries (CF), Nutrien (NTR), and Mosaic (MOS) have jumped between 5% and a whopping 35% since January, leaving the broader S&P 500 in the dust. The reason isn't just about farms; it's about a map and a very narrow, very important strip of water.
The Strait of Hormuz is that strip of water. If you follow oil markets, you know it's a big deal—a lot of crude passes through there. But it turns out roughly one-third of the entire world's fertilizer trade also sails through this pinch point. With U.S.-Israeli strikes on Iran throwing the region into disarray, that supply chain is now in jeopardy. And the timing couldn't be worse, with the Northern Hemisphere's spring planting season kicking off. This isn't just a trading floor drama; it's a story that could hit dinner tables.
"Fertilizer markets have already reacted quickly, with prices rising roughly 30% in less than two weeks since the conflict began," Hunter Swisher, CEO of agricultural technology company Phospholutions, told MarketDash. "That kind of move reflects how interconnected the fertilizer system is with global energy production, raw material inputs, and shipping routes."
A Chokepoint For More Than Just Oil
So, what exactly is moving through that strait? Gulf nations are fertilizer powerhouses. They account for about 30% of globally traded urea—the world's most popular nitrogen fertilizer—and roughly 20% of ammonia, which is what you make urea from. The conflict puts both the finished products and the natural gas needed to make them at risk.
"Volatility in natural gas prices is translated into urea via ammonia, as we have already seen. Both large fertilizer importers and food-importing regions are vulnerable to fertilizer costs and availability," said Dr. Maksim Sonin, a Stanford-affiliated energy expert.
And it's not just nitrogen. Nearly half of all the sulfur exported globally goes through the Strait of Hormuz, according to the Fertilizer Institute. Sulfur is a key ingredient for making phosphoric acid, which is the foundation for phosphate fertilizers. "When disruptions occur in that region, it doesn't just affect one product — it creates ripple effects across the entire fertilizer supply chain," Swisher added.
Markets Are Reacting, Fast
You can see the panic in the numbers. The price of urea at the important New Orleans import hub has rocketed from around $475 per metric ton before the conflict to as high as $683. That's a nearly 44% spike at its peak. The stock market is pricing in the chaos. CF Industries, the biggest U.S. ammonia producer and a pure-play on nitrogen, is the star of the show, up about 37% since January. Nutrien has gained around 20%, and Mosaic is up roughly 6%.
It's part of a broader commodity frenzy. Wheat futures are flirting with multi-year highs, and crude oil briefly topped $100 a barrel. When the world's breadbasket and gas tank get nervous, everything else does, too.
Why Spring Planting Is Suddenly a Race Against Time
This is where the story gets urgent. About half of the nitrogen used on U.S. corn crops is applied in the spring. A ship loading fertilizer in the Persian Gulf today takes roughly 30 days just to reach the U.S. coast. Then it needs another three to four weeks to get to the farms in the middle of the country. Do the math: product that's stuck now might simply not arrive before farmers have to make their final planting decisions.
"If those shipments are blocked during the spring planting season, it could affect fertilizer availability in markets such as India and Bangladesh, raising the risk of lower crop yields across South Asia and parts of Latin America and potentially feeding food price inflation into the global cost base in the second half of 2026," explained supply chain security expert David Fairnie.
The dominoes are already falling. QatarEnergy had to halt production at the world's largest single-site urea plant. Manufacturers in India have cut output, and Bangladesh has scaled back operations at several domestic fertilizer facilities because the flow of feedstocks from the Gulf has tightened up.
Could This Be Worse Than 2022?
You remember 2022. The Russia-Ukraine war sent grain markets into a tailspin. Analysts are now saying this situation is structurally different—and could be more severe.
"Instead of disrupting the grain supply directly, fertilizer disruptions affect the system upstream by making grain more expensive to produce and potentially reducing global output," Swisher said.
Think of it this way: in 2022, the problem was getting existing grain out of Ukraine. Now, the problem is making new grain anywhere more expensive to grow. European producers, who are still dealing with the high natural gas prices that followed Russia's invasion, don't have much spare capacity to help. Other suppliers outside the Gulf could theoretically ramp up, but building or restarting that capacity takes time—a luxury the spring planting calendar does not provide.
Is There a Way Out?
So, what fixes this? "Faster restoration of the usual route would be best. If that is not possible in the short to mid run, then increased production by capable non-Gulf suppliers, along with easing of export restrictions and re-routing, could help," Sonin suggested.
There's also talk of more direct protection. The Trump administration has promised naval escorts for fuel tankers moving through the strait. The American Farm Bureau Federation is pushing for those protections to explicitly cover fertilizer shipments, too.
"These supply chain shocks are expected to drive already record-high input prices even higher at a time when farm margins are already extremely tight, and many farmers are underwater," said AFBF President Zippy Duvall.
It's a classic geopolitical squeeze play. A conflict in one corner of the world pinches a vital shipping lane, which jacks up the price of a critical farm input, which threatens to make food more expensive for everyone. And for now, the market's hottest trade is betting that the squeeze is only going to get tighter.
