“What I don’t understand is why the US buck is still high relative to other currencies.”
Because, sadly enough, despite the 99% decrease in value of the dollar since 1913, the dollar is still the most stable and valuable of the world’s major currencies.
However, the main thing propping up the dollar right now (aside from the short-term effects of massive Fed money manufacturing) is the fact that the U.S. dollar functions as a world currency. If enough of these various de-dollarization schemes succeed, the dollar collapse will be greatly accelerated from just the effects of Fed money printing alone.
