World economy crisis

"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 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?

"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.

"Despite huge deficits, interest rates on 10-year Treasury bonds have hovered around 3.5%. In time of financial crisis, investors have sought the apparent sanctuary of government bonds. But the correct conclusion to draw is not that major governments (such as Japan and the United States) can easily borrow as much as they want. It is that they can easily borrow as much as they want until confidence that they can do so evaporates - and we don't know when, how or whether that may happen."
