Urea, the world's most common nitrogen fertilizer, has fallen 36% from its April peak, erasing the war's risk premium even though the Strait of Hormuz is still shut.

Key takeaways

Urea fertilizer has fallen 36% from its April peak, erasing the price spike the Iran war caused — even though the Strait of Hormuz is still closed.
The fall is dragging corn, wheat and other crops down too, because the same fear that lifted both prices is now deflating.
The relief is uneven: fuel costs for farms are still high, the underlying risk isn't resolved, and Brazil's import-reliant farmers were already hurt by the spike.

The spike that’s deflating

The fertilizer price surge that hit farms when the US-Israeli war on Iran began is reversing fast. Prices for granular urea — the world’s most common nitrogen fertilizer — have plunged more than 30% since mid-April, wiping out the gains the conflict triggered [1]. In New Orleans, granular urea dropped to $453.50 per short ton this week, the lowest since February 6 and down 36% from the April peak, the highest level since 2022 [2].

When the war started, the effective closure of the Strait of Hormuz choked off about a third of globally traded urea supplies [1]. Nearly half of the world’s urea exports come from countries caught up in the conflict, according to the Fertilizer Institute, an industry body [2]. Prices soared, and farmers scrambled for alternatives.

Now the fear is fading. “The Iran war risk premium that swept through crop and fertilizer markets is rapidly evaporating as fears of prolonged supply disruptions fade,” Bloomberg reported [1]. The strait is still not reopened — the US and Iran are only trying to reach a deal to reopen it [2]. What changed is not the supply. What changed is the expectation.

Why the crops are falling too

The fertilizer drop is pulling food prices down with it. The Bloomberg Agriculture Spot Index, which tracks 10 of the world’s most-traded crops, fell to its lowest level since March 5 [1]. Corn, wheat and other farm products are sliding as the input-cost fear unwinds.

Here’s the mechanism. Urea is made largely from natural gas, and it feeds the corn, wheat and rice that feed most of the planet. When traders feared a long war would keep fertilizer scarce, they priced crops higher too — a poorer, costlier harvest seemed to be coming. As the fertilizer fear deflates, the crop fear deflates with it. The same anticipation that lifted both is now lowering both.

The timing helped. US farmers have largely finished applying fertilizer for the spring planting season, so demand for urea has dropped just as the panic eased [2]. Oversupply met weak demand. In some cases, US prices have fallen below those in import-reliant countries like Brazil, which could even push US fertilizer out as exports [2].

The bill that didn’t land evenly

The relief is real but uneven. Two cautions sit underneath it.

First, energy prices are still elevated [1]. Diesel and fuel costs for US farms have kept climbing even as fertilizer fell back — the war squeezed farm inputs through two channels at once, and only one of them has relaxed [3]. A farmer running tractors and grain dryers is still paying the war’s fuel premium even as the fertilizer premium drains away.

Second, fertilizer stays sensitive to any flare-up in Middle East tensions [1]. The premium evaporated because the feared future faded, not because the underlying risk was resolved. A single bad week of news could put it straight back.

And the spike already did lasting damage abroad. Brazil, which has spent this century roughly doubling its farmland to challenge US growers, relies heavily on imported fertilizer [1]. Its farmers cut back purchases when prices spiked, and many now sit on land producing thin returns or losses, accumulating debt [1]. “Profitability just isn’t there,” one farmer in Goias state told Reuters. “Expansion is something everyone is rethinking right now” [1]. Unlike US farmers, who can skip a year’s fertilizer on rich land and still get a decent harvest, few Brazilian growers have that cushion — or a government bailout to fall back on [1].

What it means at the till

For shoppers, the easing fertilizer price is a small loosening of one knot in food inflation — cheaper inputs eventually mean less upward pressure on grain-based food. But it’s slow, partial, and reversible. The crops that just got cheaper are wholesale crops; the loaf and the cereal box lag months behind, and the elevated fuel cost is still working its way through every truck that moves food. The headline says the war premium is gone. The fuller story is that one premium left, another stayed, and the thing everyone feared still hasn’t actually happened.

02 · Lesson · why it matters

The price of a disaster that never happens

Markets don't just price what's true now — they price what people fear is coming, and someone always pays for the fear whether or not the thing arrives.

A price that rose on nothing physical

In mid-April, the price of urea — the fertilizer that feeds most of the world’s grain — shot to its highest level in four years. By this week it had fallen 36%. Almost all the way back down.

Here’s the strange part. Nothing physical changed between the top and the bottom. The Strait of Hormuz, which carries a third of the world’s traded fertilizer, was closed when the price spiked. It is still closed now, with the price back near where it started. No new shipment got through. No mine reopened. No factory came online.

The price didn’t track the supply. It tracked the story about the supply.

Anticipation is a price

When the war started, traders did what markets always do: they looked at the future and bought it now. A long war meant scarce fertilizer, which meant poorer harvests, which meant dearer food. So the price of fertilizer jumped — and the price of corn and wheat jumped with it — not because any of that had happened, but because people believed it was about to.

That extra cost has a name: a risk premium. It is the amount you pay today to hold something whose future looks dangerous. It is real money, paid by real farmers, for a danger that has not yet occurred and might never.

Then the fear faded. A deal to reopen the strait started to look possible. The “prolonged supply disruptions” people had braced for stopped feeling certain. And the premium evaporated — fast, because a price built on a guess about the future falls the moment the guess loses its grip.

The whole round trip was a market pricing a disaster, then un-pricing it, while the disaster itself simply never showed up.

The same fear lifts and drops the whole chain

Watch how far the single fear reached. It didn’t stay in fertilizer.

Fertilizer feeds grain, so when fertilizer looked scarce, grain looked scarce too — the Bloomberg index of the world’s ten most-traded crops rose and then fell in step with the urea price. One anticipation moved a dozen markets at once, because they’re all links in the same chain: gas makes fertilizer, fertilizer grows grain, grain becomes bread.

The fear travels as far as the chain does. A trader’s guess about a strait in the Middle East lifted the cost of a sack of fertilizer in Iowa, which lifted the priced-in cost of a corn harvest not yet planted, which will eventually nudge a cereal box on a shelf an ocean away. None of those people fear the same thing, or even know each other. They are priced together anyway, by an expectation none of them set.

Some pay the premium and never get it back

Here’s where the cost stops being even. A premium that comes and goes looks harmless if you can wait it out. Many cannot.

Brazil’s farmers buy most of their fertilizer from abroad. When the spike hit, they couldn’t absorb it, so they cut back — and many now sit on land producing thin returns or losses, taking on debt. The premium has since drained away in the market. It has not drained away from their books. They paid for a feared future at the top, and the relief arrived too late to undo the choice the fear forced on them.

Meanwhile the relief itself is partial. Fertilizer fell back, but fuel for tractors and grain dryers stayed high — the war squeezed farms through two pipes, and only one loosened. The premium you most want gone is often not the one that leaves.

What the whole looks like from inside

It is tempting to read this as a clever fact about markets: prices anticipate, premiums unwind, watch the spread. That is the half that makes you sharp. The other half is harder.

You are not standing outside this. The premium for a feared future is folded quietly into the price of nearly everything you buy — the grocery bill that carries a war you’ll never see, the insurance that prices a flood that may not come, the cost of borrowing that bakes in a recession that might not arrive. You pay for anticipated disasters constantly, in small amounts, and you cannot itemize them. When the disaster doesn’t happen, you rarely get a refund; the price just drifts back, and you never learn what you paid for the fear.

No single seat sees the whole of it. The trader sees the spread, not the Brazilian farmer’s debt. The farmer sees the debt, not the cereal shelf. The shopper sees the shelf, not the strait. Each is pricing, and being priced by, a future that exists mostly as a shared guess — and the safest thing to carry out of that is not a trading rule, but a smaller confidence in any single read of what’s coming.
