Fertilizer stocks decline after US President Donald Trump signals that the United States is working on a deal to buy potash from Belarus. Multiple outlets report that Trump posted on Truth Social that the US is “working on a massive” arrangement, with pricing described as substantially lower than current prices.

Market reaction is concentrated among fertilizer producers and related suppliers, with shares of Intrepid Potash, CF Industries, and Mosaic dropping toward session lows on the news. The move follows earlier US actions on tariffs involving Canada, after the US and Canada failed to reach a late trade agreement; the tariffs reportedly include exemptions for key imports such as oil, gas, and potash.

Some coverage also ties the announcement to competing claims about supply capacity. One outlet cites reporting from Interfax that Belarus President Alexander Lukashenko says Belarus lacks the capacity to supply potash to Western markets, creating uncertainty about whether the proposed US-Belarus arrangement can be executed on the stated terms.
