If there is de-dollarization I don’t see it. There was some chance under the Euro, but the Europeans violated the first principle of a reserve currency and violated the property rights of depositors and investors.
The USA doesn’t do that ever. It’s a core principle. And we have the debt capacity because of the size of our economy and strength of our military to do so.
A common reserve currency needs common interests. This is why the competition by hostile states is irrelevant. They can’t really do without the dollar. There is some hope that digital currency like bitcoin will sometime provide an alternative, but that system is still slow and fragile enough that governments are unwilling to try it at scale.
So for now, there are two currencies: the dollar, and oil. Everything else is a hedge (gold).
