The gradual decline in the dollar and improvement in the current account deficit would provide the best outcome for the economy. When the dollar rises in value, U.S. exports become more expensive and import prices fall. Between 1995 and 2002, the dollar gained about 30% in value (see chart below). As a result, the U.S. trade deficit has grown from about 1.5% of GDP to 6.4% in the first quarter, far beyond sustainability. As a rough rule of thumb, international economists have estimated that the currency must depreciate by 10% to bring about a 1 percentage-point reduction in the current account as a share of GDP. In order to bring the deficit down to a sustainable level (less than 3% of GDP), the dollar must fall by at least 30% to 40% to reduce export prices and achieve the needed increase in export growth, relative to imports. A falling dollar will also raise import prices, slowing import growth and increasing demand for goods produced in the United States.
Only large inflows of foreign investment prevented larger declines in the dollar in the first quarter. Foreign central banks, led by Asian governments, financed more than one-third of the current account deficit in this period. The Asian central banks' decision to promote their export-led growth by propping up the dollar is the largest barrier to needed dollar adjustments. If governments fail to bring about the desired orderly depreciation, markets could burst the dollar bubble, with far-reaching negative consequences for the United States and global economies. |
