Comdoll is a nickname for “commodity dollars.”
Currencies like the Australian, Canadian, and New Zealand dollars are usually called comdolls because their respective economies are highly dependent on exporting commodities. Australia, for one, is the third largest gold producer in the world while Canada has the sixth spot in the world’s oil production.
Investors often need to get their hands on comdolls if they want to trade commodities. This is why the comdolls’ price action is usually correlated with commodity prices.
