Everyone's Watching Oil Prices. The Real Hormuz Crisis Is Fertilizer.

Brent crude is expected to jump 9% when markets open Monday morning. Goldman Sachs says $110 a barrel if the Strait of Hormuz stays closed. JPMorgan says $120 to $130.

Those are the numbers everyone's watching.

Here's the number almost nobody is: one-third of the world's nitrogen fertilizer exports pass through that same 21-mile-wide chokepoint.

Oil grabs headlines. Fertilizer feeds people.

The Strait of Hormuz carries 20% of global oil and 20% of seaborne natural gas. That's well documented. But the strait also handles a massive share of the world's fertilizer trade — chemicals that farmers from Iowa to India depend on to grow food.

Qatar alone is the world's largest exporter of urea, a critical nitrogen fertilizer. That urea ships through Hormuz. Saudi Arabia and Oman are also major fertilizer exporters. Their shipments go through the same strait that Iran's Revolutionary Guards told vessels they can't use.

"No ship is allowed to pass the Strait of Hormuz," the IRGC broadcast via VHF radio on Saturday, according to the EU naval mission Aspides.

Three tankers have already been attacked near the mouth of the Persian Gulf. Oil majors, trading houses, and shipping companies have suspended transit. The chokepoint isn't just threatened. It's functionally closed.

We've seen this before — and it wasn't pretty

When Russia invaded Ukraine in 2022, fertilizer prices tripled in months. Russia and Belarus together produce about 40% of the world's potash exports. When those shipments were disrupted, farmers across Africa and South Asia couldn't afford to fertilize their crops.

The result: lower yields, higher food prices, and a hunger crisis the World Food Programme called the worst in a generation.

Now imagine a similar disruption, but for nitrogen fertilizer — the most widely used type on Earth. Nitrogen-based fertilizers are responsible for feeding roughly half the world's population. Without them, global crop yields would collapse.

Qatar's urea alone feeds farms across South and Southeast Asia, Africa, and Latin America. Those shipments are now stopped.

The food price chain

Here's how it works.

Fertilizer prices rise because Hormuz is blocked. Farmers pay more for inputs or go without. Crops yield less. Food gets scarcer. Prices go up at markets from Lagos to Lima.

The people hit hardest aren't in countries that produce oil. They're in countries that import food — which is most of the developing world.

The UN already warned last week that the world has entered an era of "water bankruptcy," with four billion people facing severe scarcity. The WFP reported a 20% increase in acute food insecurity since 2020. Six countries are already at the worst level of food emergency: Sudan, Yemen, Nigeria, DRC, Palestine, and Haiti.

A fertilizer disruption doesn't create a new crisis. It pours accelerant on one that's already burning.

Asia is most exposed

Japan sources 75% of its oil imports through Hormuz. South Korea, 60%. India and China are the third and fourth most dependent nations. But it's not just their energy supply at risk — it's their food supply chain.

India is the world's second-largest consumer of fertilizer. It imports heavily from Gulf producers. If those shipments stop, India's next crop cycle faces a direct threat. With 1.4 billion people to feed, there's no margin for error.

China has been stockpiling commodities for months, anticipating disruption. India hasn't. South Korea and Japan have strategic petroleum reserves but no equivalent for fertilizer.

Strategic reserves won't help here

Countries can release oil from strategic reserves. The US Strategic Petroleum Reserve, depleted by pandemic-era drawdowns, can still provide a short-term buffer. China's reserves are substantial. OPEC+ has pledged modest output increases. Saudi Arabia and the UAE have bypass pipelines that can move some oil around Hormuz.

None of that applies to fertilizer.

There is no strategic fertilizer reserve. There's no bypass pipeline for urea. There's no OPEC equivalent that can ramp up production elsewhere overnight.

If Hormuz stays closed for weeks, not days, the fertilizer market has no shock absorber. Prices rise. Supplies tighten. Farmers in the Global South — the ones who spend the highest percentage of their income on food — absorb the blow first.

Two crises from one chokepoint

The Hormuz crisis is really two crises sharing one waterway.

The oil crisis is expensive and disruptive. It'll spike energy prices, hammer airline stocks, and dominate Monday's market open. Countries with reserves and alternatives will manage. It'll hurt, but it's survivable.

The fertilizer crisis is slower and quieter. It won't make Monday's headlines. But if shipping doesn't resume within weeks, it could reshape the next growing season across Asia, Africa, and Latin America. And unlike oil, there's no reserve to tap, no alternative route, and no quick fix.

Forbes reported Sunday that the fertilizer angle is the "more enduring story" from the Hormuz closure. The Independent confirmed that one-third of global fertilizer trade passes through the strait.

The world is watching oil prices. The more dangerous number is the one nobody's tracking yet.

What happens next

If the strait reopens within days, this stays a scare. Oil settles, fertilizer shipments resume, and the crisis becomes a footnote in a larger war.

If it stays closed for weeks, two things happen simultaneously: energy markets adjust (painfully but predictably), and fertilizer markets enter unknown territory. Countries that couldn't afford food at current prices face prices they've never seen.

The headlines will tell you about oil. Keep watching for the word "fertilizer." When it starts appearing in the same sentences as "Hormuz," the second crisis has arrived.
