The International Dollar Standard and the Sustainability of the U.S. Current Account Deficit

April 2001 For more than 20 years, the United States has run current-account deficits with the rest of the world—and is now the world’s largest international debtor. Because the world is on a dollar standard, the United States is unique in having a virtually unlimited international line of credit which is largely denominated in its own currency, i.e., dollars. In contrast, foreign debtor countries must learn to live with currency mismatches where their banks’ and other corporate international liabilities are dollar denominated but their assets are denominated in the domestic currency. As these mismatches cumulate, any foreign country is ultimately forced to repay its debts in order to avoid a run on its currency. But however precarious and over-leveraged the financing of individual American borrowers—including American banks, which intermediate such borrowing internationally—might be, they are invulnerable to dollar devaluation. In effect, America’s collective current-account deficits are sustainable indefinitely. Working Papers Index(This abstract was borrowed from another version of this item.)
