The phosphate market should, by most measures, be correcting. Demand is weakening, buyers are stepping back, and market sentiment is clearly pointing lower. But five countries account for virtually all global supply, and the disruption to the Strait of Hormuz has done more than restrict export routes for finished product. It has also blocked anhydrous and sulfur, the two largest variable costs in phosphate production, from reaching manufacturers, creating a structural cost floor that price pressure alone cannot break.
Josh Linville serves as Vice President of Fertilizer at StoneX, where he oversees the global fertilizer department including the trade desk and covers supply, demand, and pricing dynamics across the major nutrient markets. His coverage spans the phosphate, urea, and specialty fertilizer supply chains that connect geopolitical disruption to farm-level input decisions across North America.
The Strait of Hormuz closure has affected the phosphate market well beyond the export routes for finished product. Anhydrous and sulfur, the two largest variable costs in phosphate production, travel through the same routes and have been equally disrupted, pressing manufacturers from both sides of the cost equation. That dynamic creates a structural floor rather than a temporary ceiling. "You drop the market back, I'm going to shut down my production, and I'm going to rebalance this because I can't produce it at a loss," Linville says, describing a producer response that constrains supply rather than reducing price. The practical outcome is a market that cannot clear through normal price discovery while input supply chains remain restricted.
Where most commodity markets have several layers of swing supply to absorb a disruption, phosphate does not. "Five countries control the phosphate market. It's China, it's Russia, it's Saudi Arabia, it's Morocco and the US," Linville notes, and the weight of that concentration becomes clear when one of the five steps back entirely. China has not exported phosphate and, in his assessment, is showing no near-term signs of resuming, with its own production difficulties compounding the supply picture. Saudi Arabia, meanwhile, has been unable to ship at its normal pace through the Strait of Hormuz; while some product has reached West Coast facilities, it falls well short of the volumes the market requires. The combined effect is that a significant share of global phosphate capacity is either absent or operating below potential, removing the swing supply the market would normally rely on to bring prices back toward demand.
With prices showing no sign of a meaningful correction, the signal from growers is unambiguous. Linville says that without a significant price move before the fall application season, the industry could face one of the weakest phosphate demand cycles it has ever recorded. Soil profiles that can support a delayed or reduced application give growers a credible alternative to buying at current levels, and many are treating it as one. "It doesn't even come close to making sense," is how he characterizes the reaction coming from buyers running the numbers. Under normal circumstances, demand destruction would be the mechanism that forces prices lower; with the cost floor in place, even a historic pullback in buying may not be enough to clear the market at pace. In Linville's view, "phosphate is going to take a little while to correct," and a Strait reopening, while constructive for the longer term, is unlikely to resolve the issue quickly.

When the Strait of Hormuz restricts the movement of anhydrous and sulfur, phosphate manufacturers face input costs that make lower prices commercially impossible. Josh Linville explains why the structural cost floor embedded in phosphate production is preventing the market correction that growers need.
As global fertilizer markets adjust to easing tensions in the Middle East, traders are shifting their focus away from political headlines and toward the physical movement of goods. Shipping access through critical trade corridors is once again becoming the dominant factor shaping supply expectations and fertilizer pricing. In June 2026, improving vessel traffic has coincided with falling urea prices and renewed confidence among exporters. The result is a rapid repricing of fertilizer markets as participants reassess supply availability rather than geopolitical risk.
Global fertilizer markets defied every supply warning this season, absorbing a Strait of Hormuz closure, halted Chinese exports, and reduced European production without a single reported shortage. The hidden buffer was not logistics or policy resilience but a quiet, widespread decision by farmers around the world to apply less nitrogen when prices pushed too high.
