Will There Be a Dollar Crisis?

"Almost everyone believes that the US current account deficit must eventually end, and that this end will involve dollar depreciation. However, many believe that this depreciation will take place gradually. This paper shows that any process of gradual dollar decline fast enough to prevent the accumulation of implausible levels of US external debt would impose capital losses on investors much larger than they currently expect. As a result, there will at some point have to be a 'Wile E. Coyote moment'- a point at which expectations are revised, and the dollar drops sharply. It is much less clear, however, whether this 'crisis' will produce macroeconomic problems." Copyright (c) CEPR, CES, MSH, 2007.
