The U.S. current-account deficit is the broadest measure of America's activity in international trade and global finance. It totaled $857 billion last year, the Commerce Department reported last week. For the fifth year in a row, the nation's current-account deficit set a record. As Federal Reserve Chairman Ben Bernanke testified last year before Congress: The immediate implication [of the nation's soaring current-account deficit] is that the U.S. economy is consuming more than it's producing, and the difference is being made up by imports from abroad, which in turn is being financed by borrowing from abroad." Last year's current-account deficit meant that Americans effectively borrowed $3.3 billion every single working day to fund the gap between their spending and their income. The accumulation of ever larger current-account deficits over the past quarter century has played an indispensable role in transforming the United States from the world's largest creditor nation into the planet's biggest debtor nation. Specifically, in 1982, America's net international investment position was a positive $236 billion. That meant that foreigners owed us nearly a quarter of a trillion dollars more than we owed them. At the end of 2005 (the latest year for which data are available), the net international investment position of the United States was a negative $2.55 trillion. In other words, we owed foreigners more than $2.5 trillion than they owed us. Since 1994 alone, America's net international investment position has deteriorated by more than $2.4 trillion.
