With the loss of military and political supremacy goes the loss of dollar supremacy. From Patrick Barron at mises.org:
Since the Bretton Woods Agreement in 1944, the dollar has been the world’s preferred reserve currency—the major trading nations of the world were willing to hold dollars in vast amounts to satisfy their need for a readily accepted worldwide payment medium. Even when, in 1971, the United States violated its solemn promise to redeem its dollars for gold at thirty-five dollars per ounce, nations were still willing to hold dollars.
Germany Shies Away from Monetary Leadership
In the mid-2010s, I was certain that Germany would abandon the euro and reinstate the deutsche mark. It was clear, especially to some German central bankers, that Germany was being cheated by the European Central Bank. Germany’s TARGET2 surplus represented a vast excess of German exports to other European Union members, who were pledging near-worthless government and corporate bonds in exchange for newly printed euros from the European Central Bank. These bonds would never be redeemed for anything of real value; therefore, it would be simple rational self-interest for Germany to quit the charade.
I predicted that such an action would cause the eurozone to collapse, make Germany’s deutsche mark the preferred unit of trade in Europe, and possibly threaten the dollar for worldwide reserve dominance. Obviously, this never happened. Why?
Dollar hegemony is ending because of imbecilic American foreign policy and the mad policy of printing too much fiat currency.
