The wolf at the door

摘要

Most economists, newspaper, have been fretting about America's huge current-account deficit and predicting the dollar's sharp decline for years. The trouble with crying wolf too often is that people stop believing you. After slipping 14% in broad trade-weighted terms since 2002, the dollar had stabilised this year, even as the current-account deficit continued to grow. This has encouraged some economists to offer theories explaining why America's current-account deficit does not matter and why the dollar need not fall further. But the dollar has now started to slide again: this week it hit $1.28 against the euro, within a whisker of its all-time low of $1.29. Trust us, the wolf is real. The dollar's latest slide seems to have been triggered by uncertainty about the presidential election and a flurry of comments from Fed officials. Robert McTeer, the president of the Dallas Federal Reserve, mused (only "theoretically" of course) that when capital inflows into America dry up, "there will be a crisis that will result in rapidly rising interest rates and a rapidly depreciating dollar that will be very disruptive".
