alt Hacker NewsUS and Canadian production is largely irrelevant to the price. These are world comodities. If worldwide production drops, prices rise. As with oil/gas producers, domestic potash producers are under no obligation to sell locally. If prices are higher in europe/asia/africa, that domestic potash will be loaded onto ships until domestic prices rise to match.
much of canadian oil should be pretty insulated and thus also the US consumption of it.
its not particularly available to the rest of the globe because you need different refining.
i find it to be kinda funny that albertan oil prices jump with global markets when albertas major complaint is about a lack of access to global markets.
Canada also doesnt have the export capacity for selling potash directly. if its being redirected away from the US, its US importers deciding they can get a better price by re-exporting it
like a "in theory in ten years from now, these other customers could swap what oil theyre using, so were gonna charge you more now just in case"
