End of the 'Exorbitant Privilage'? More than $5 trillion current account deficit and more than $50 trillion net debt by 2030 and the international reserve status of dollar

"...To a large extent, the US external deficit has an internal counterpart: the budget deficit. Higher budget deficits generally increase domestic demand for foreign goods and foreign capital and thus promote larger current account deficits. But the two deficits are not "twin" in any mechanistic sense, and they have moved in opposite directions at times, including at present. The latest projections by the Obama administration and the Congressional Budget Office (CBO) suggest that both in the short run, as a result of the crisis, and over the next decade or so, as baby boomers age, the US budget deficit will exceed all previous records by considerable margins. The Peterson Institute for International Economics projects that the international economic position of the United States is likely to deteriorate enormously as a result, with the current account deficit rising from a previous record of six percent of GDP to over 15 percent (more than $5 trillion annually) by 2030 and net debt climbing from $3.5 trillion today to $50 trillion (the equivalent of 140 percent of GDP and more than 700 percent of exports) by 2030. The United States would then be transferring a full seven percent ($2.5 trillion) of its entire economic output to foreigners every year in order to service its external debt.

This untenable scenario highlights a grave triple threat for the United States. If the rest of the world again finances the United States' large external deficits, the conditions that brought on the current crisis will be replicated and the risk of calamity renewed. At the same time, increasing US demands on foreign investors would probably become unsustainable and produce a severe drop in the value of the dollar well before 2030, possibly bringing on a hard landing. And even if the United States were lucky enough to avoid future crises, the steadily rising transfer of US income to the rest of the world to service foreign debt would seriously erode Americans' standards of living..."
