The deep river of private money that helped knit together the global economy has abruptly dried up, new government figures show. As the global financial crisis grew more severe this summer, foreigners sold almost $90 billion of U.S. securities - the greatest quarterly fire sale by overseas investors since the government began keeping track in 1960. U.S. investors also are retrenching; they unloaded about $85 billion worth of foreign holdings in the quarter, says the Commerce Department's Bureau of Economic Analysis. We've had a global panic. Everyone is pulling their money home," says economist Adam Posen of the Peterson Institute in Washington, D.C. That's bad for economic growth in the U.S. because it threatens to starve capital-hungry companies and entrepreneurs. But it's especially serious for emerging-market countries that rely heavily on outside financing. Capital flows into countries such as South Korea, Turkey and Brazil were evaporating even before the mid-September Lehman Bros. bankruptcy made things worse. The reversal of private capital flows signals an abrupt end to a nearly two-decades-long era of financial globalization, says economist Brad Setser of the Council on Foreign Relations. Private flows into and out of the U.S. for purchases of stocks, corporate bonds and federal agency bonds have dropped from around 18% of economic output to near zero "in a remarkably short period of time," Setser says.
