I was wondering how it’s possible too. The article mentions this exchange:
https://www.ice.com/products/15/Coffee-C-Futures
My take:
Futures traders decided the price would go up 70%, and were very wrong. This led to the standard “C” contract (set by the ICE exchange) price being too high, tanking demand. If you want to participate in the futures market, you need to have a license you get from the exchange.
I’m sure some producers will try to bypass the exchange market that manages all that, but, ultimately, someone will have to lose a bunch of money. It’ll either be the traders (futures contracts end up being worthless) or the producers (coffee ends up rotting or being refused by the silo).
The article suggests it’s the latter, which makes me wonder how powerful the exchange is, and what happens if you just start freighting bags of coffee around.
