Most important take away

The Iran war and Strait of Hormuz closure is hitting fertilizer markets at the worst possible time — right before Northern Hemisphere spring planting season. The Urea-to-corn price ratio is about to set an all-time record, meaning fertilizer has never been more expensive relative to what farmers earn. With ~45% of the world’s tradable Urea coming from the Middle East, no strategic reserves, and China’s export ban still in effect, there is no good alternative supply source, and US corn yields are expected to drop from 186 to 182 bushels per acre this year.

Summary

Actionable Insights & Investment Advice:

• Fertilizer prices are spiking at the worst possible time. Urea prices have surged ~25% in the past week alone, reaching ~$600-700/metric ton. The Urea-to-corn price ratio hit 124 last week (all-time high is 143) and is expected to set a new record this week. This means fertilizer has never been more expensive relative to crop prices for farmers.

• US farmers are better positioned than international farmers, but still hurting. US has domestic natural gas and Urea production capacity. India and EU countries that depend on Middle Eastern natural gas for fertilizer production face far worse outcomes. Chapter 12 farm bankruptcies are already rising in 2025.

• Corn yields expected to fall. Bloomberg Intelligence expects US corn yields to drop from 186 to 182 bushels/acre due to reduced nitrogen application. This flows into food prices over a 1-2 year timeline as the harvest (September/October) moves through the food production system.

• No strategic Urea reserves exist. Unlike oil, there is no strategic reserve for fertilizer. Storage economics don’t favor long-term accumulation because warehouse owners maximize value by turning inventory, not holding it.

• Even if the Strait reopens tomorrow, it takes 2-3 weeks minimum for fertilizer plants to restart (2-3 days natural gas burn), load vessels, and ship. Oil will likely get priority over fertilizer for Strait passage.

• Three supply-side legs have been kicked out simultaneously: China’s export ban (since 2021), Russian supply sanctioned/difficult to acquire, and now the Strait of Hormuz closure cutting off 45% of tradable Urea.

• Watch food prices 12-24 months out. Lower yields from reduced fertilizer application won’t show up on dinner plates immediately — harvest happens September/October, then moves through milling, processing, and distribution over 1-2 years.

• Smaller farmers are more vulnerable. Large-scale operations have business relationships and scale to secure supply. Small farmers making individual purchasing decisions face the worst of the price pressure.

Stocks/Investments Mentioned:

• Corn futures — Lower yields expected; prices likely to rise
• Urea/fertilizer commodity prices — Egyptian granular Urea near $700/ton; New Orleans Urea at $570
• Morocco/phosphate — Morocco expanding phosphate production; phosphate is to Morocco’s economy what oil is to Saudi Arabia
• Nitrogen fertilizer producers — US-based producers advantaged due to low domestic natural gas prices
• Agricultural commodities broadly — Supply shock could drive prices higher across the complex

Chapter Summaries

Chapter 1: Why Timing Matters — The Spring Planting Season The US-Israeli war against Iran comes at the worst possible time for agriculture. Historically, wars avoided spring sowing and fall harvest seasons. Urea prices have spiked 25% in the past week as farmers prepare for spring planting.

Chapter 2: What is Urea and How is it Made Urea is the most common form of nitrogen fertilizer (46% nitrogen). It’s made from natural gas → ammonia → granular Urea. Plants are co-located with natural gas sources because gas is expensive to ship. Half the world’s population exists because of conventional fertilizer (Haber-Bosch process).

Chapter 3: The Supply Crisis — Three Legs of the Stool 45% of the world’s tradable Urea comes from the Middle East. China has had an export ban since 2021. Russian supply is sanctioned. This leaves only Egypt and the US as significant alternative sources — grossly insufficient to replace lost Middle Eastern supply.

Chapter 4: The Storage Problem Unlike oil, there are no strategic Urea reserves. Urea has strong seasonality (demand only 2 months/year), and warehouse economics favor inventory turnover over stockpiling. This means there’s no buffer to absorb the current shock.

Chapter 5: The 2022 Parallel and the Urea-to-Corn Ratio In 2022, Urea hit $1,100/ton after the Ukraine invasion. But the current crisis is arguably worse because the Urea-to-corn price ratio is setting all-time records. Farmers face the worst economics ever for buying fertilizer relative to what they earn from crops.

Chapter 6: Farmer Response Options Farmers can: reduce application rates, switch from corn to soybeans (less nitrogen needed), switch among nitrogen products, or not plant at all. US farmers are best positioned; Indian and EU farmers face far worse conditions. Senators in DC are already hearing from farmers requesting relief.

Chapter 7: Food Price Implications Lower yields won’t hit food prices immediately. Corn harvested in September/October moves through the food system over 1-2 years. But the risk of outright famine in some regions (not the US) is real when you shock global food production at this scale.
