Frighteningly, like the rush into tech stocks, then the rush into real estate, and then the rush into commodities, the rush into U.S. government bonds has created a Treasury bubble. In a cruel twist of economic fate, passage of an aggressive Obama administration stimulus plan could further inflate that bubble - before popping it.

The United States of America is an expensive household to run. In order to pay the nation's bills, the U.S. government levies taxes. When expenditures exceed tax revenue, the government has to borrow money. The United States borrows money by ordering the Treasury Department to sell government IOUs to investors in the form of Treasury bills, notes and bonds, known as "Treasuries."

How much does the government owe? As of Friday, according to TreasuryDirect.gov, total U.S. public debt stood at $10,620,397,126,433.54 ($10.62 trillion) - and counting.
