"The future of the U.S. current account--and thus of the U.S. dollar--depend on whether foreign investors will continue to add U.S. assets to their investment portfolios. However, even under optimistic scenarios, the U.S. current account deficit is likely to go through a significant reversal at some point in time. This adjustment may be as large of 4% to 5% of GDP. In order to have an idea of the possible consequences of this type of adjustment, I have analyzed the international evidence on current account reversals using both non-parametric techniques as well as panel regressions. The results from this empirical investigation indicate that major current account reversals have tended to result in large declines in GDP growth. I also analyze the large U.S. current account adjustment of 1987-1991"--National Bureau of Economic Research web site.
