The global macro trends shaping commodity markets and the actual profitability of cash crops on the ground. Neither has been kind to the people growing the food.
Farming isn’t an easy business and most outsiders don’t fully appreciate how challenging it can be. It’s brutally capital-intensive with massive overhead, heavy capex, long payback periods, seasonal cash flows and thin margins and no pricing power. You take whatever the market gives you, the day it gives it to you and you hope it’s enough to cover seed, diesel, fertilizer, labour and debt.
For most farmers, it’s more than a business. It’s a calling. The reason they keep at it isn’t the return on capital or equity. It’s the fulfilment that comes from time spent in nature, working with it rather than against it.
Then came the war in the Middle East. Over the past two months, the razor-thin margins farmers were already running on have gotten dramatically worse.
Since the war began, both crude oil and nitrogen fertiliser prices have surged by more than 50%. Urea fertiliser is the most widely used nitrogen fertiliser on Earth and nitrogen fertilisers accounts for 60 to 65% of every pound of fertiliser that goes into the ground globally. It is, quite literally, what feeds the world. No nitrogen, no yield. Right now, the world’s supply of it is being choked from two directions at once.
The first choke point is the Strait of Hormuz, through which roughly 35% of all global nitrogen fertiliser flows. With shipping lanes disrupted, that supply has effectively been cut off. The second is China , they are a global swing producer of nitrogen fertiliser, responsible for around 15% of world supply. Within days of the conflict starting, Beijing quietly halted its nitrogen exports. Then they simultaneously stopped buying U.S. corn. Resulting in input costs exploding while corn and wheat prices have stayed essentially flat.
David Friedberg laid this out plainly on the All-In Podcast recently , explaining that China is using this moment to apply extraordinary leverage on American agriculture. They are taking advantage of a global supply shock to bankrupt the very farmers who feed the nation.
To make matters worse, the world's largest nitrogen-producing facility, based in Qatar, has been damaged in the war. A plant of this scale takes three to five years to repair. Building a new facility from scratch takes even longer and can take around seven years to complete. There is also basically no down time for these facilities still running, almost every existing plant in the world already runs 24 hours a day, 365 days a year, at full capacity. There is no spare production. There is no excess capacity. There is no relief valve.
Chart A: Urea price (USD/ton), trailing 12 months. Note the near-vertical spike from late February onward, coinciding with the start of the war and the closure of the Strait of Hormuz. - urea price chart via Trading Economics.
Chart B: SAFEX wheat price in ZAR (red line, 2026) versus the 2025 price and 5- and 10-year seasonal averages. South African wheat is currently trading at roughly 5,784 ZAR/ton — below historical benchmark and moving in the opposite direction of the seasonal trend. - SAFEX data via Cornelius Odendaal.
To put this in perspective for South African farmers, the macro picture is arguably worse than what their American counterparts are facing. Over the past 12 months, the Rand has strengthened by roughly 10% against the US dollar. For grain producers it cuts the wrong way. Global wheat is priced in US dollars and SAFEX prices ultimately track that international parity. So when the dollar weakens against the Rand, every dollar of underlying wheat value translates into fewer Rand of profit.
After analysing data provided by a local agricultural economist in the Southern Cape and applying the post-war cost shock to current input prices , nitrogen fertiliser up roughly 55% and diesel up 40% since the start of the conflict , I arrived at a set of concerning conclusions, illustrated below for each cash crop.
Table 1 — 2026 Grain Branch Analysis, Southern Cape (War-Adjusted)
Input cost data provided by André Anker Fourie , adjusted for the war-driven cost shock with nitrogen fertiliser up 55% and diesel up 40%. These figures represent the projected reality for Southern Cape grain producers in 2027 if current input prices hold from now until next planting season.
Barley
-
War-adjusted input cost: R15,883/ha
-
Profit margin: 6.9%
-
Break-even yield: 3.26 t/ha (expected: 3.5 t/ha)
Canola
-
War-adjusted input cost: R17,098/ha
-
Profit margin: 8.5%
-
Break-even yield: 1.92 t/ha (expected: 2.1 t/ha)
Wheat
-
War-adjusted input cost: R16,176/ha
-
Profit margin: −1.1% (loss)
-
Break-even yield: 3.34 t/ha (expected: 3.3 t/ha)
Chart 1 — Return on Equity on R100,000/ha Land Valuation (War-Adjusted)
Return on equity per crop after the war-driven cost — measured against an average Southern Cape dryland farmland valuation of R100,000/ha in 2025. Canola returns 1.59%, barley 1.18%, wheat −0.18%. All three sit far below the 8.5% money market rate.
Chart 2 — Net Profit Margin as % of Gross Income (War-Adjusted)
Net profit margin per crop after applying the war-driven cost shock - measured against April 2026 SAFEX prices. Wheat is now operating at a loss. Barley and canola hold mid-single-digit margins, but every crop sits well below the 10.25% prime lending rate.
The Light at the End of the Tunnel
Looking at the numbers, it is easy to feel completely discouraged. But there is a light at the end of this tunnel and surprisingly, it is coming from Wall Street.
For the first time since 2022, institutional money has flipped net long on wheat. They are no longer hedging the downside they are betting on a massive price appreciation.
Their thesis is simple but profound. While most U.S. farmers are insulated from the current nitrogen spike for the 2026 spring planting, the fall season is the true inflection point. If fertilizer stays at these punishing levels, American farmers will simply refuse to pay these elevated prices. They will pivot to soybeans a crop that fixes its own nitrogen from the atmosphere rather than draining it from the soil. In a high-input-cost world, the economic choice is obvious.
Wall Street is front-running the inevitable. They are positioning for a massive oversupply of soybeans and a critical undersupply of wheat and maize over the next 12 to 18 months. Combine this acreage shift with the severe drought already ravaging the U.S. and grain prices have nowhere to go but up.
For South African farmers, this is not an immediate rescue. But it is a clear signal that the tide is turning. The smartest money in the world is betting on it.
