K+S stock soars 36% in 2024—then faces new potash market threats
K+S, the German potash producer, has seen its share price climb by 36% since January. The rise came amid speculation about supply disruptions in the Strait of Hormuz. But recent shifts in geopolitics and market dynamics are now reshaping the outlook for the company.
The rally in K+S shares began earlier this year, fuelled by concerns over potential blockages in the Strait of Hormuz. Investors bet on tighter potash supplies, pushing the stock higher. Goldman Sachs also boosted its stake in the company, raising its holdings to 15.7% by March 12—up from 13.4%. Most of this increase came through derivatives like call warrants and swaps.
Yet, the geopolitical tensions that drove the price surge have since eased. A bigger challenge now looms: the possible return of Belarusian potash to global markets. In early 2026, US special envoy John Coale signalled that Belarus—once responsible for 20% of worldwide potash exports—could resume large-scale shipments. Since then, global potash prices have dropped by 15-20%.
Trading activity has spiked in key markets like Chicago and Vancouver. Spot prices fell from $350 per tonne to around $280 by mid-March, lowering fertiliser costs for major buyers in Brazil, India, and China. The re-entry of Belarusian supplies would further squeeze K+S's pricing power, adding pressure on its revenues.
K+S faces a shifting landscape as geopolitical risks recede and competition intensifies. With Belarusian potash poised to return, the company's producer prices are likely to face additional downward pressure. The coming months will show how these changes affect its market position and financial performance.
