Fertilizer: The Invisible Crisis Nobody Is Pricing

"Food production was a prerequisite for the development of guns, germs, and steel."

– Jared Diamond, Guns, Germs, and Steel

Urea.

You've probably never thought about it. But it feeds half the planet's crops.

The price of urea (Middle East) — the nitrogen compound that keeps the world's fields productive — hit $730 per ton. Up 80% in a matter of days (chart 1).

Why?

The Strait of Hormuz doesn't just carry oil. It carries fertilizer. The Gulf and Middle East account for 34–50% of all globally traded urea and 25–35% of total nitrogen fertilizer trade. Iran alone exports 10–12% of global urea. Qatar's Ras Laffan — one of the largest nitrogen plants on Earth — declared force majeure on March 2.

That supply is now offline. And the ships that would carry it can't get insured — the same war-risk coverage pulled for oil tankers was pulled for fertilizer carriers.

The consequence is simple but devastating.

No insurance. No ships. No fertilizer. No nitrogen in the soil. No grain from the fields. Higher bread prices in Cairo, Lagos, Dhaka, and Jakarta.

Jared Diamond wrote 400 pages on exactly this mechanism in Guns, Germs, and Steel — the civilizations that controlled food production first controlled everything else. That was 13,000 years ago. The logic hasn't changed. We explore his Pulitzer Prize-winning blueprint in this week's arvy Book Club.

India imports over 40% of its urea from the Middle East. That supply has been cut — right as spring planting peaks in March and April. The window does not wait.

The World Bank estimates that every 1% rise in fertilizer prices transmits a 0.45% rise in food commodity prices. Urea is up 80% in a matter of days. Do the math.

The oil crisis is priced. Every trading desk on Earth has recalculated Brent. The fertilizer crisis is invisible. It moves slower. It hits harder.

As we wrote last week in our arvy's Weekly on Maersk: shipping is the fever thermometer of the global economy. Fertilizer is the fever itself.

Enter the four companies that control most of the world's crop nutrients.

CF Industries.

Nutrien.

Mosaic.

ICL.

The Big Four — Who Does What

Fertilizers come in three flavors: nitrogen (N), phosphate (P), and potash (K). Together, they form the NPK trinity — without which modern agriculture simply does not function (chart 2).

Let's explain each in a few words to keep our Friday morning brains, next to a coffee, working:

• Nitrogen (N) is the growth engine. It makes plants grow taller, greener, faster. Think of it as protein for crops — without it, leaves turn yellow and yields collapse. It's produced from natural gas, which is why the Hormuz crisis hits it hardest.
• Phosphate (P) is the root builder. It drives root development, flowering, and energy transfer within the plant. Think of it as the plant's skeleton — without it, crops stay weak and fail to mature. It's mined from phosphate rock, primarily in Morocco, China, and Florida.
• Potash (K) is the immune system. It regulates water, strengthens cell walls, and helps plants resist drought and disease. Think of it as the plant's shield — without it, crops are vulnerable to stress. It's mined from deep underground deposits, primarily in Canada, Russia, and Belarus.

Now to the market leaders. The four key players each own a piece of this puzzle.

• Nutrien (NTR) is the world's largest fertilizer company by capacity. Based in Canada, it leads in potash production — sitting on some of the richest geological reserves on the planet — and is fully integrated across nitrogen, phosphate, and agricultural retail distribution. Nearly 30% of its earnings comes from selling directly to farmers. Think of it as the Walmart of agriculture: mine it, make it, sell it.
• CF Industries (CF) is the dominant force in nitrogen. Over 90% of its production is fed by low-cost US natural gas, which gives it a structural cost advantage over European and Asian competitors paying multiples for the same feedstock. When urea prices spike — as they do right now — CF prints cash like few others can.
• Mosaic (MOS) is the powerhouse in phosphate and potash, with major mining operations in Florida and Canada and a vast distribution network in Brazil. It is the most directly exposed to agricultural demand cycles in both hemispheres.
• ICL Group (ICL) is the Israeli-based diversifier. Potash, phosphates, and specialty chemicals — from fertilizers to flame retardants to food additives. It's the most differentiated of the four, with roughly 70% of earnings coming from specialty-driven businesses.

All four are currently surging. Shares are up 10–30% since the Hormuz crisis began. Earnings estimates are being revised upward.

Sounds like a "Good Story"?

Not so fast.

Why Fertilizers Are Not a "Good Story" for Us

Last week, we explained why Maersk — despite its geopolitical relevance — doesn't belong in the arvy portfolio. The reasons were cyclicality, weak capital allocation, and no economic moat.

The fertilizer industry shares all three. But it amplifies them.

Here's what makes fertilizers uniquely hostile to long-term compounding.

1. The Farmer Budget Trap. Fertilizer demand follows farmer psychology. When crop prices are high, farmers splurge on inputs — demand surges, prices explode. When crops tank, they cut back brutally: defer applications, reduce acreage, switch to cheaper alternatives. Booms are sharp but short-lived, tied to narrow planting windows. Busts linger, because farmers remember the pain. Shipping is seasonal. But it doesn't have this "memory effect" from end-users who can literally skip a cycle.
2. Energy as the Killer Variable. Nitrogen is 70–80% natural gas by cost. Every nitrogen producer is a leveraged bet on energy prices — not a compounder. CF Industries thrives when US gas is cheap and global gas is expensive. But that's a spread trade, not a moat. And when Hormuz disrupts, it doesn't just delay ships — it cuts off the ammonia itself. You can reroute a container ship. You cannot reroute a chemical plant.
3. The Boom Cash, Bust Trap. In peak years, fertilizer companies generate massive free cash flow — and return it via buybacks and special dividends. Why? Because new capacity takes years and risks overcapacity. But unlike ships, which can be scrapped or idled, fertilizer plants are fixed and location-locked. Companies over-expand in booms, then bleed in busts. The textbook commodity curse.
4. The Cost Leadership Illusion. CF has cheap gas. Mosaic has potash reserves. Nutrien has retail. These sound like moats. They're not — eroded by export bans, government subsidies, and new low-cost supply entering the market. No patents. No switching costs. Just being the cheapest in a glut-prone market. Great in booms. Useless in busts.

And one more layer shipping doesn't face: regulation. Nitrogen runoff is an increasing environmental concern. Carbon taxes on ammonia production are coming. Green ammonia mandates are being discussed. These pressure margins long-term without clear reinvestment upside.

The result?

Immensely volatile net profit margins and, hence, a "Good Story" for a trade (chart 3). Not for a portfolio.

Time to check the "Good Chart".

Volatility Is the Name of the Game

If there is one chart that captures the fertilizer industry, it is this: fertilizer stocks rose over 800% from its lows into the Global Financial Crisis peak (chart 4). Then it collapsed. Then it rose again into 2022. Then it collapsed again.

This is what cyclical investing looks like. Violent upswings. Violent drawdowns. And the illusion that "this time it's different" during every boom.

The current spike — driven by Hormuz — fits the pattern perfectly. Shares are surging on supply disruptions. Earnings estimates are being revised upward. Momentum is strong.

But momentum in cyclicals is a dangerous friend. It arrives fast, stays briefly, and leaves without warning. The global order book tells the same story as always: new potash capacity from competitors and projects expanding phosphate at scale are just a matter of time and in process. Once geopolitical tensions ease, the supply wave arrives — and with it, the inevitable price compression.

We've seen this movie before. In 2008. In 2022. And we'll see it again.

Cyclical stocks can produce extraordinary returns — if you time them right. But timing is the operative word. And at arvy, we don't time. We compound.

So, we watch the fertilizer industry the same way we watch Maersk: with fascination, with respect for its complexity, and from a safe distance.

Because in the end, the best fertilizer for a portfolio isn't nitrogen, phosphate, or potash.

It's patience.
