Not A Good Sign

FRANKFURT Finance ministers and central bankers have long fretted that at some point, the rest of the world would lose its willingness to finance the United States' proclivity to consume far more than it produces - and that a potentially disastrous free-fall in the dollar's value would result.

But for longer than most economists would have been willing to predict a decade ago, the world has been a willing partner in American excess - until a new and home-grown financial crisis this summer rattled confidence in the country, the world's largest economy.

On Thursday, the dollar briefly fell to another low against the euro of $1.3927, as a slow decline that has been under way for months picked up steam this past week.

"This is all pointing to a greatly increased risk of a fast unwinding of the U.S. current account deficit and a serious decline of the dollar," said Kenneth Rogoff, a former chief economist at the International Monetary Fund and an expert on exchange rates. "We could finally see the big kahuna hit."
