Potash (MOP)

Potash is the potassium nutrient, and the dominant product is MOP (muriate of potash), which is potassium chloride mined from ancient evaporite seams left by dried-up seas. Unlike nitrogen and phosphate, there is essentially no chemistry: ore is mined, crushed, and purified into a finished fertilizer, so potash economics turn on ore grade, mine depth, and freight rather than on gas or sulphur. World MOP production is roughly 70 to 75 million tonnes a year, and supply is strikingly concentrated. Canada, above all the Saskatchewan basin worked by Nutrien and Mosaic, is the largest source; Russia (Uralkali) and Belarus (Belaruskali) are the other low-cost giants; with smaller output from China, Germany (K+S), and the Dead Sea producers of Israel and Jordan.

The market's defining event was the 2021-2022 sanctions shock. Belarus, a landlocked exporter that shipped through Lithuania, was sanctioned after 2020, and then Russia was sanctioned after its 2022 invasion of Ukraine. Together the two had supplied roughly 40 percent of the world's potash, and removing them sent MOP above 1,200 dollars a tonne in 2022, a record. The trade rerouted rather than vanished: Belarusian tonnes found their way out through Russian ports and rail to China, Russian exports recovered, and prices normalized toward a 300 to 400 dollar range by 2024 and 2025. By 2026 Belarusian capacity was expanding again, with the Nezhinsky project commissioning, even as the market stayed relatively tight on strong demand.

Demand is led by the big agricultural importers: Brazil, China, India, the United States, and Southeast Asia, with Brazil the single largest buyer. The Canadian producers sell their export tonnes jointly through Canpotex, a marketing consortium that negotiates the large annual contracts with China and India that effectively set a global price floor. Those contract settlements, alongside Brazilian spot demand, are the events the whole market watches.
