The article discusses America's current-account deficit and a prediction that the dollar will decline sharply. The dollar's latest slide seems to have been triggered by uncertainty about the presidential election and a flurry of comments from Fed officials. The dollar has fallen by over 30% against the euro since 2001, but its trade-weighted index has fallen by much less because of heavy intervention by Asian central banks, aimed at holding down their currencies against the dollar. Some economists argue that America can sustain its large current-account deficit for at least another decade, without a sharp fall in the dollar, because it will be happily financed by China and other Asian countries. In a series of papers Michael Dooley, David Folkerts-Landau and Peter Garber at Deutsche Bank have argued that the present arrangements resemble a revived Bretton Woods, the system of fixed exchange rates after the second world war. Currency intervention by Asian central banks helps to explain why America has so far been able to finance its deficit without higher American bond yields or a bigger fall in the dollar. George Magnus, an economist at UBS, argues that the parallels with Bretton Woods are superficial. One big difference is that in the 1960s the United States ran a current-account surplus and was a net creditor to the rest of the world. Today, America is the world's biggest debtor, which could undermine the dollar's role as an anchor currency. Another important difference is that, unlike under the Bretton Woods regime, most Asian countries have scrapped capital controls or where they still exist, as in China, they are leaky. Under Bretton Woods there was no real alternative to the dollar as a reserve currency. Today there is the euro, into which Asians could diversify.
