End of the Dollar?

In this new monetary world, moreover, the U.S. government will not be able to finance its budget deficits so cheaply, since there will no longer be as big an appetite for U.S. Treasury securities on the part of foreign central banks.

Nor will the U.S. be able to run such large trade and current-account deficits, since financing them will become more expensive. Narrowing the current-account deficit will require exporting more, which will mean making U.S. goods more competitive on foreign markets. That in turn means that the dollar will have to fall on foreign-exchange markets – helping U.S. exporters and hurting those companies that export to the U.S.
