The next nail in the coffin of the US dollar is going to be when the rest of the world decides to dump the dollar as the reserve currency.
The Bretton Woods arrangement gave the dollar a serious edge- commodities and other global trade was all exchanged in dollars. Oil was expressed in dollars. Foreign nations had to keep dollars just to trade with each other .
Then we closed the “gold window” so we could print money like it was going out of style.
These countries are still holding trillions of our dollars and other debt instruments we created in order to spend more than we actually produced.
If Russia, China, and India team up economically (it’d be a more natural arrangement than what we have) and dump all their dollar holdings during a realignment, what happens?
What happens is our already inflated domestic currency is joined by the trillions of overseas dollars rushing back home. Hyperinflation.
