WHO believes in a strong dollar? Robert Rubin, Bill Clinton’s treasury secretary, most certainly did. John Snow, his successor but two, says he does but nobody believes him—if only because he wants other countries’ currencies, in particular the Chinese yuan, to go up. Mr Snow’s boss, President George Bush, in one of his mercifully rare forays into economics last week, also said he wants a muscular currency: “My nation is committed to a strong dollar.” Again, it would be fair to say that this was not taken as a ringing endorsement. “Bush’s strong-dollar policy is, in practical terms, to maintain a pool of fools to buy it all the way down,” a fund manager was quoted by Bloomberg news agency as saying. It does not help when the chairman of your central bank, Alan Greenspan, whose utterances on the economy are taken rather more seriously than Mr Bush’s, has said the day before that the dollar seems likely to fall: “Given the size of the current-account deficit, a diminished appetite for adding to dollar balances must occur at some point,” were his exact words. The foreign-exchange market immediately decided that it was sated, and the dollar fell to another record low against the euro.
Mr Greenspan’s words were of huge moment, and not just because he spoke clearly, unusual though this was, nor because the Federal Reserve rarely comments on foreign-exchange movements. No, Mr Greenspan’s words were significant because he was tacitly admitting what right-thinking economists the world over have long believed: that the emperor has no clothes.
