*** The question now confronting us is how large a current account deficit in the United States can be financed before resistance to acquiring new claims against U.S. residents leads to adjustment. Even considering heavy purchases by central banks of U.S. Treasury and agency issues, we see only limited indications that the large U.S. current account deficit is meeting financing resistance.
Yet, net claims against residents of the United States cannot continue to increase forever in international portfolios at their recent pace. Net debt service cost, though currently still modest, would eventually become burdensome. At some point, diversification considerations will slow and possibly limit the desire of investors to add dollar claims to their portfolios.
