Swimming in red ink

Can a government check bounce? Not such a crazy question. The U.S. government is borrowing so much money right now that these kind of questions are starting to be asked. Here, Robert Samuelson of Newsweek explores the possible implications of a government swimming in a sea of red ink, and the "precariousness and novelty of the current situation."

The idea that the government of a major advanced country would default on its debt -- that is, tell lenders that it won't repay them all they're owed -- was, until recently, a preposterous proposition. Argentina and Russia have stiffed their creditors, but surely the likes of the United States, Japan or Great Britain wouldn't. Well, it's still a very, very long shot, but it's no longer entirely unimaginable. Governments of rich countries are borrowing so much that it's conceivable that one day the twin assumptions underlying their burgeoning debt (that lenders will continue to lend and that governments will continue to pay) might collapse. What happens then?

The question is so unfamiliar that the past provides few clues to the future. Psychology is crucial. To take a parallel example: the dollar. The fear is that foreigners (and Americans, too) lose confidence in its value and dump it for yen, euros, gold or oil. If too many investors do that, a self-fulfilling stampede could trigger sell-offs in U.S. stocks and bonds. People have predicted such a crisis for decades. It hasn't happened yet. The currency's decline has been orderly, because the dollar retains a bedrock confidence based on America's political stability, openness, wealth and low inflation. But something could shatter that confidence -- tomorrow or 10 years from tomorrow.
