Umm.  My mom is really scared about what it means if the USD looses its place at the benchmark.  I think she expects we'll wind up in the position Germany was in between ww1 and 2

Unless the federal government severely mishandles the situation that is unlikely. You'll probably see some major devaluing if it does happen suddenly enough, but it's more likely for the USD value to slowly drop over a decade or two as currency reserves become available for sale instead of being kept in vaults as, well, a reserve.

And that's if the USD indeed loses its global currency reserve monopoly. I'm not so certain of that happening.
