Inside the global fertilizer crunch

The framing correction is the most useful thing in the episode, and both speakers arrive at it independently. A closed chokepoint looks like a textbook commodity shock: prices spike, shipping resumes, prices settle. Linville’s version is that the strait was a shot of adrenaline nobody needed on a market already tight on 1 January, for three reasons that have nothing to do with Iran. China, historically the world’s largest phosphate exporter by a wide margin and usually the second or third largest urea exporter, had halted exports. Europe has been running nitrogen production at roughly 75% of normal since gas prices blew out in the Russia-Ukraine sequence, which takes about 3.5 million tons of urea and a couple of million tons of UAN off the market every year. That second one is worse than it sounds, because European farmers do not stop fertilizing when European plants stop producing; the missing tons become European demand on the world market, so the same event subtracts supply and adds demand at once. And nothing cushions any of it. A strategic fertilizer reserve gets discussed but does not work, because fertilizer breaks down in storage far faster than oil and because nobody can answer who would get it, at what price, and how it would move.

Onto that, the closure removed about a third of the world’s tradable urea, along with a good chunk of the world’s anhydrous ammonia, since three of the biggest exporters of both sit behind the strait. The cascade is what makes it unusual. Those plants have had to slow or stop entirely, because covered storage fills up and there is nowhere to put finished product once it cannot sail. LNG is stuck behind the same waterway, and that LNG feeds India’s nitrogen plants, so India, which produces more than 30 million tons of urea a year, saw production fall to 50 or 60% of normal at the worst point. Phosphate gets squeezed through a third channel, the cost and scarcity of sulfur and anhydrous that go into making it. And there is no relief valve, because substitution only works inside a silo. A grower can switch between urea, UAN and anhydrous ammonia if the equipment and storage allow, since a unit of nitrogen is a unit of nitrogen, but nitrogen cannot stand in for phosphate or potash. They do different jobs. So a phosphate shortfall is simply a phosphate shortfall.

The reason this has not yet become a food story is partly timing and partly demand that happened to be absent. Northern Hemisphere spring application is finished, so whatever was in place is what got used, and summer is normally the quiet, cheap part of the year. Linville expects a stalemate instead: sellers with every reason to hold out for high prices, buyers looking at grain prices and refusing to engage. Two demand absences also cushioned things. Australia’s drought suppressed fertilizer buying, which he is careful not to call fortunate, and which reverses the moment rain arrives, since the product is not in position. India’s demand, by contrast, does not flex at all, because the government subsidizes the gap between the farmer’s price and the world price, so India simply pays whatever the tender costs. The odd consequence is that reopening the strait would be bearish. The 900,000 to a million tons sitting on vessels in the Persian Gulf were bought for spring delivery, and dumping them into the year’s weakest demand window would push prices down while replacing none of the tons that were never produced. Buyers would walk away from purchases they no longer need, and because urea degrades as humidity works into a ship’s hold over months, those particular cargoes may end up trading at a discount for quality risk. The other branch is blunter: if the strait is still closed when his son goes back to school in the autumn, allocation becomes an auction, and whoever bids highest gets the tons.

Supply cannot respond on a useful timescale, which is the part with the longest shadow. A world-scale nitrogen plant costs three to five billion dollars, takes years from decision to first ton, and offers no way to guarantee the margin investors would demand, so almost nobody outside the industry will build one. Worse, from Linville’s point of view, the new North American capacity that is being built is anhydrous ammonia, which North America already produces enough of, rather than urea, which is the one product it genuinely depends on imports for. He is explicit that he supports cleaner production and equally explicit that his worry is about food: much of that new capacity is green or blue ammonia, and he thinks the technology may not be as ready as the industry assumes. The other apparent escape, insulating North American prices by restricting exports the way China has, runs into its own trap. US prices track world prices because the export arbitrage exists, which is why nitrogen can be expensive while Henry Hub gas is cheap; but banning urea exports would discourage the imports the US relies on. Linville is a free-market partisan about this and says so plainly: the more governments step into these markets the worse it gets, however well intentioned they are.
