Wheat markets face fresh supply worries as fertilizer costs soar.
Fertilizer shock tightens supply chains
Fertilizer prices have jumped sharply since strikes in the Middle East disrupted shipping through the Strait of Hormuz, traders and analysts say. Chris Lawson, vice-president of market intelligence and prices at CRU, told reporters that around 30% of exportable urea suppliers are effectively sidelined because the waterway is no longer functioning normally. The United Nations estimates roughly one-third of the world’s seaborne fertilizer trade transits the strait.
Those blockages are being felt in benchmark nitrogen markets. Chris Yearsley, chief executive officer and head of nitrogen at Profercy, tracked New Orleans nitrogen prices rising from about $350 a short ton in late December to roughly $600 by 10 March. FOB granular urea in Egypt — often treated as a barometer for global nitrogen supplies — has been seen near $700 per tonne, up from about $400–$490 before the conflict, according to market notes cited by Oxford Economics’ Alpine Macro.
Fertilizer plays a major role in crop production costs. The US Department of Agriculture says nitrogen fertiliser can account for roughly one-fifth of production costs for major crops such as corn. The American Farm Bureau calculates that the United States imports about a quarter of the fertiliser it uses, including roughly 18% of its nitrogen needs. And when a concentrated share of global production is cut off, prices and availability move fast.
Farmers feel the squeeze at planting
For growers the timing couldn't be worse. Rodney Bushmeyer, who runs Bushmeyer Farms in Illinois, said higher fertiliser bills have eaten into margins over the past five to six years and that the latest spike is piling on. "It's not sustainable in the long term," Mr Bushmeyer said. "We can do that for a few years, but eventually it'll put us out of business."
Matt Bennett, chief executive officer of AgMarket and a seventh-generation grain farmer, described the moment simply: "It's not a great time for the grower." Both men stressed that spring planting — when nitrogen demand for crops such as wheat becomes immediate — leaves producers little flexibility.
Dawid Heyl, co‑portfolio manager for global natural resources at Ninety One, warned that nitrogen is an input farmers can't defer. "You can't skip a season of nitrogen," he said, noting that inventories can be drawn down only so far before yields start to fall. That creates a narrow window in which shortages shift from being a cost problem to being a supply problem.
Why wheat is particularly exposed
Wheat is grown across far larger areas than many other crops and is a staple in global grain trade. In 2021 world wheat production was about 771 million tonnes and the crop covered roughly 220.7 million hectares, figures that underline how widely exposed global food systems are to disruptions in fertiliser supply. Much of the global trade in wheat moves in markets that are sensitive to changes in expected yields and input costs.
Nitrogen fertiliser is central to achieving typical wheat yields. If growers cut back on applications because of cost or supply difficulties, agronomists warn production could fall later in the season. Chris Lawrence at a market intelligence firm observed that when a big chunk of traded nitrogen is at risk, inventories can mask the impact only briefly; the real effects on yields and exports tend to arrive later in the crop cycle.
This delay is important for traders and processors. Markets tend to factor in risks that might affect future supply and demand. If analysts and farmers expect a poorer crop because of reduced fertiliser application, prices can move before the harvest. Shipping disruptions and rising nitrogen and urea prices have raised worries about wheat supplies in the coming months.
How weather compounds the problem
Weather is the other variable. In major wheat regions, timing matters: early-season moisture, spring temperatures and the timing of fertiliser application together determine crop establishment and eventual yields. This spring, planting decisions are being taken against a backdrop of constrained fertiliser supply, meaning farmers have to decide whether to press ahead with full nutrient programmes or to ration inputs and accept lower yield prospects.
Where weather reduces the effectiveness of later nutrient applications — for example, through heavy rains that wash away applied nitrogen or dry spells that limit uptake — the combination with reduced fertiliser use can push expected output lower than either factor would alone. That interaction is what traders worry about when they talk about upside risk for wheat prices.
Market and policy implications
Short-term, the most visible effect has been on fertiliser contracts and freight rates. In the medium term, the combination of high input costs and tight export capacity could alter planting decisions, change crop mixes and reshuffle global grain flows. Producers in importing countries may seek alternative sources, and some governments could move to restrict exports to protect domestic supplies — steps that would tighten global markets further.
Oxford Economics’ Alpine Macro noted that urea and ammonia prices have surged by approximately 50% and 20% respectively since the conflict began, underscoring how quickly cost pressures can build. Analysts at trade and pricing firms emphasise that fertiliser markets are less liquid than oil or metals markets, so price moves can be exaggerated and visibility into physical flows is worse.
Higher fertilizer costs squeeze margins for commodity companies and push up prices for flour millers and food makers. Consumers will feel the impact depending on crop yields and how much of the cost increase gets passed on.
Outlook for the season
Supply-chain constraints mean the next few months will be critical. Traders will watch rainfall and temperature across major wheat belts, and they will watch whether shipping through the Strait of Hormuz resumes at scale. If maritime trade flows normalise, some of the pressure on nitrogen prices could ease; if not, inventories held by distributors and farmers will be drawn down.
Market participants say there's a time lag between the disruption and crop outcomes. Chris Yearsley of Profercy warned that prices had already nearly doubled from late-December levels to early March in some nitrogen benchmarks, signalling a fast-moving cost shock. That shock will be monitored against field conditions as spring unfolds.
For now, growers like Mr Bushmeyer are making difficult calculations about inputs and cashflow, while analysts and traders try to price the likely effect on global wheat supplies and shipments. The season's end will show whether higher fertiliser costs and weather together pushed yields down or whether inventories and adaptive decisions kept markets on an even keel.
