The most important invention in history turns air into bread. Cheap money turned that miracle into a fragile oligopoly. The Iran war just kicked it. You’ll feel it at the checkout in about six months, and there’s nothing you can do about it now.
The Invention That Feeds Half the World
In 1909, a German chemist named Fritz Haber figured out how to turn air into ammonia. In 1914, Carl Bosch scaled it for industrial production. Two men, working in a decade that also produced the airplane and the assembly line, quietly pulled off something more consequential than either: they discovered how to feed a world that would otherwise have starved.
Before Haber-Bosch, nitrogen fertilizer came from guano mined in South America and nitrates scraped from the Atacama Desert. The supply was finite, expensive, and geographically constrained. The world’s population in 1900 was 1.6 billion. Today it is 8 billion…
That difference exists in large part because Fritz Haber discovered how to pull nitrogen from the air and convert it into something crops could eat.
Haber won the Nobel Prize in 1920. It was arguably the most consequential award in the prize’s history. Scientists now estimate that roughly half of the nitrogen in the human body came through the Haber-Bosch process. And that means, half the people alive today exist because of that reaction.
Which makes what’s happening to the fertilizer supply chain right now one of the most important stories that almost nobody in mainstream financial media is covering.
The fertilizer supercycle is back. And the grocery bill is a lagging indicator.
We’ve Been Here Before: The 1973 Template
There is a pattern to fertilizer crises, and it is as reliable as a metronome.
Energy shock → natural gas spike → fertilizer production costs explode → farmers cut applications → crop yields fall → food prices surge.
That’s because the whole chain takes six to twelve months to play out, because agriculture runs on planting cycles, not quarterly reports.
The first modern fertilizer crisis hit in 1973–74. The OPEC oil embargo sent energy prices skyward. Natural gas, which is both the feedstock and the energy source for Haber-Bosch ammonia production, accounting for 70–90% of nitrogen fertilizer’s variable cost, became ridiculously expensive. In real, inflation-adjusted terms, the fertilizer price spike of 1973–74 was actually larger than the one we saw in 2022. Food prices followed. The 1970s stagflation that haunts every central banker’s nightmares had fertilizer running underneath it the whole time.
The pattern repeated in 2007–08, when the China-driven commodity supercycle peaked. Fertilizer demand surged alongside everything else. Urea prices hit records. Food prices spiked globally. The World Food Programme reported riots in over 30 countries. The 2008 food crisis was as much a fertilizer crisis as it was a financial one, but the financial crisis got all the headlines.
It repeated again in 2021–22, when Russia’s invasion of Ukraine removed two of the world’s largest fertilizer exporters from global markets simultaneously. Russia supplies roughly 23% of global ammonia exports, 14% of urea, and 21% of potash. Belarus, closely allied with Russia, supplies another 20% of global potash. The sanctions that followed sent wholesale fertilizer prices up 60% in 2021 and an average of 132% higher in 2022 compared to 2020. Farmers across the developing world cut back. Yields fell. Food insecurity spread. The crisis is still not fully resolved.
Now a fourth shock has arrived, and it is hitting a system that never fully recovered from the third.
Urea Prices: Four Spikes, One Direction
The Oligopoly That Easy Money Built
Here is where the fiat money thesis enters, and where the current crisis gets structurally worse than its predecessors.
In the 1980s, the US nitrogen fertilizer industry had 59 production facilities. By the mid-2000s, it had 22. Over those two decades, cheap credit enabled a wave of mergers and acquisitions that consolidated the industry into a handful of dominant players. The same story played out globally.
Today, according to Farm Action’s Agriculture Consolidation Data Hub, the top four nitrogen producers control more than 80% of regional production capacity. Two firms control more than 90–95% of phosphate and potash capacity worldwide. The fertilizer market is not a free market. It is an oligopoly, and like all oligopolies, it behaves accordingly when a supply shock provides cover.
Farm Action, a farmer advocacy group, sent a letter to President Trump and federal antitrust regulators in March 2026 documenting exactly what happens when oligopolists control a market that farmers cannot avoid during a compressed seasonal planting window. Their letter is worth quoting at length. Not because it’s politically surprising, but because it comes from the ground level, from people who actually buy fertilizer.
“Just a few years ago, dominant fertilizer companies used global supply shocks as justification for dramatic price increases that far exceeded underlying cost pressures, generating record profits while farmers absorbed severe input cost spikes. With renewed geopolitical instability now impacting fertilizer shipments, there is a real risk of a repeat.”
— Farm Action letter to President Trump, March 11, 2026
Farm Action called on the administration to investigate anti-competitive conduct, review whether key fertilizer inputs should be designated as scarce resources under the Defense Production Act, and act before the planting season locked in this year’s decisions. Congress has responded with the Fertilizer Transparency Act of 2026 with bipartisan legislation requiring USDA to publish weekly fertilizer price data, and Senator Josh Hawley has demanded a DOJ investigation into possible price gouging. These are good impulses. They are also far too late for the 2026 growing season, which is already underway.
The corn growers’ associations put numbers to the squeeze:
DAP fertilizer at $851 per ton, up $108 from a year ago.
MAP fertilizer at $879 per ton, up $71.
Potash up $52 to $488.
Overall corn production costs are projected to increase an additional 4% this year, on top of three consecutive years of losses. American Farm Bureau Federation analysis shows farmers entering the 2026–27 crop year with accumulated losses exceeding $50 billion over the prior three years. When the Farm Action letter’s author asks Congress for help, the response has been bills. Bills take time. The planting window does not wait for bills.
The Iran War Kicks the System
And then the Iran war began.
On February 28, 2026, the US and Israel launched military operations against Iran. Within days, Iran moved to restrict passage through the Strait of Hormuz, the narrow maritime chokepoint through which 40% of the world’s nitrogen fertilizer exports flow.
The Persian Gulf is not just an oil highway. It is a fertilizer highway. Qatar, with its vast natural gas reserves, supplies roughly 15% of global urea and 50% of internationally traded urea. Iran itself is a major ammonia producer. Egypt, supplying 8% of global urea trade, depends on natural gas from Israel’s Leviathan and Karish fields; with those exports disrupted by the conflict, Egyptian plants including MOPCO and Abu Qir have gone into emergency shutdowns. On March 18, 2026, Iran struck Qatar’s Ras Laffan natural gas terminal, which produces 20% of the world’s LNG. State-owned QatarEnergy estimates repairs will take up to five years.
The market’s response has been immediate and severe. Granular urea prices hit $665 per ton as of March 31, up 37% in a single month. Ammonia is up 20% since the war began. Fertilizer plants in India, Algeria, Slovakia, and elsewhere have slowed or shut as natural gas costs make production uneconomic. China has restricted fertilizer exports, tightening the global supply further. Brazil, which imports the majority of its fertilizer and feeds a significant portion of the world’s soy and corn supply, is facing severe input cost inflation with no domestic alternative.
US farmers are responding the only rational way they can:
Switching crops.
Current projections show US corn acreage dropping to 93 million acres in 2026, down from 99 million in 2025, as farmers pivot to soybeans, which require far less nitrogen. Less corn means less supply. Less supply means higher prices. Those higher prices will arrive at your grocery store in the second half of this year, embedded in the cost of chicken, beef, pork, and every processed food that contains corn syrup, corn starch, or corn-fed protein.
The World Food Programme estimates the current fertilizer shortage could push an additional 45 million people into extreme hunger by late 2026.
Unlike oil, there is no global strategic nitrogen reserve….
There is no buffer. When the Strait closes, the price goes vertical, and the consequences are baked in on agricultural time (sowing and reaping cycles).
The Planting Window Doesn’t Wait
Let’s connect the dots the mainstream isn’t connecting.
The Haber-Bosch process requires natural gas. The Middle East has the cheapest natural gas in the world. So the Middle East became the world’s dominant fertilizer producer. Cheap money then enabled the consolidation of the remaining global production into a handful of oligopolists who, by Farm Action’s own documentation, have a demonstrated history of using supply shocks to extract maximum profit from farmers who cannot delay planting.
Now the Middle East is a war zone. The Strait of Hormuz is contested. Qatar’s LNG terminal has been bombed and won’t be repaired for five years. Urea is up 37% in a month. Farmers are making irreversible planting decisions right now based on the economics they face today. Those decisions will determine grocery store prices in October, November, December.
The 1973 oil shock produced the 1974–75 food crisis. The 2022 Russia-Ukraine war produced the 2022–23 food price surge. The lag is reliable. The 2026 Iran war will produce a food price crisis in late 2026 and into 2027, and it is already locked in. A ceasefire tomorrow would not undo the planting decisions already made, the applications already skipped, the acreage already shifted from corn to soybeans.
This is inflation that doesn’t show up in a CPI report until it’s too late to hedge…
This is the inflation that hits the people who can least absorb it, families who spend a significant portion of their income on food. This is what the monetary system produces when you let cheap credit consolidate essential industries into oligopolies, build global supply chains on a single chokepoint, and then blow up the chokepoint.

One thought on "The Fertilizer Supercycle Is Back: The Most Important Supply Chain You’ve Never Thought About"
Excellent article! Imo like helium, certain markets should be protected for the use of urea & ammonia. You would think many more reps other than Sen Hawley would be vocally supportive of their farmer constituents. This is a huge deal for the family farmers. And great, last thing the world needs is more soybean seed oil in our food chain! It’s inflammatory and an estrogen disruptor.
