The Buck Stopped Then

It was the very lack of gold-standard inhibition that permitted the buildup of titanic dollar balances overseas. At the end of 2007, no less than $9.4 trillion in dollar-denominated securities were sitting in the vaults of foreign investors. Not a few of these trillions were the property of Asian central banks. So, although the United States has run heavy and persistent current account deficits — $6.7 trillion in total since 1982 — they have been “deficits without tears,” to quote the French economist Jacques Rueff. The dollars American debtors sent abroad America’s creditors sent right back in the shape of investments in American stocks, bonds and factories.

Under the Bretton Woods system, worried foreign creditors would long ago have cleaned out Fort Knox. But, conveniently, the dollar is uncollateralized and unconvertible. America’s overseas creditors hold it for many reasons. Some — notably Asian central banks — acquire dollars simply to help make their exports grow. But even the governments that scoop up dollars for no better reason than to manipulate their own currency’s value presumably put some store in the integrity of American finance.

As never before, that trust is being put to the test. In the best of times, the Treasury and the Federal Reserve pretended as if the dollar were America’s currency alone. Now, in some of the worst of times, Washington is treating its vital overseas dollar constituency as if it weren’t even there.
