Forgive my subject ignorance, but is the CAD also just backed by "Faith in government" as seen here in the US? I know the petrodollar is more or less what really keeps the USD going so I'm curious what keeps Canada's supply "stable."
So the US dollar isn't really backed by oil because the ratio of oil you get for the dollar isn't fixed. Back when the dollar was backed by gold you could use it to get a specific amount of gold. Now you can still use it to get gold, on the market, but the ratio fluctuates.
The US dollar is backed by taxation. If you want to have an income, which we all do, you now have to pay taxes. That requires to to obtain or already have some USD to be able to give it in order to not go to jail. Because nearly everyone is in the same situation everyone values USD and therefore you can reliably give it as a form of payment, and the recipient is even more willing to accept it knowing it is a broadly accepted form of payment. This is why people in the US exchange USD and people in Canada exchange CAD. If both have value and both can be used as money why wouldn't one just win out as a currency? Because US citizens are taxed in a different currency than Canadians.
So CAD is backed by the threat of going to jail.
