here is the danger that the dollar's safe-haven status will be lost. Foreign investors—private and official alike—hold dollars not simply because they are liquid but because they are secure. The U.S. government has a history of honoring its obligations, and it has always had the fiscal capacity to do so.
But now, mainly as a result of the financial crisis, federal debt is approaching 75% of U.S. gross domestic product. Trillion-dollar deficits stretch as far as the eye can see. And as the burden of debt service grows heavier, questions will be asked about whether the U.S. intends to maintain the value of its debts or might resort to inflating them away. Foreign investors will be reluctant to put all their eggs in the dollar basket. At a minimum, the dollar will have to share its safe-haven status with other currencies.
My calculations suggest that the dollar will have to fall by roughly 20%. Because the prices of imported goods will rise in the U.S., living standards will be reduced by about 1.5% of GDP—$225 billion in today's dollars. That is the equivalent to a half-year of normal economic growth. While this is not an economic disaster, Americans will definitely feel it in the wallet.
