"The United Nations' crime and drug watchdog has indications that money made in illicit drug trade has been used to keep banks afloat in the global financial crisis . .

The United Nations Office on Drugs and Crime had found evidence that 'interbank loans were funded by money that originated from drug trade and other illegal activities. . ' "

But wait a minute, the US government said this years ago:

"The International Monetary Fund estimates that the amount of money laundering occurring on a yearly basis could range between 2 and 5 percent of the world's gross domestic product--or somewhere between $600 billion and $1.5 trillion. Estimates come from a variety of sources based upon both macroeconomic theories and on microeconomic approaches. The U.S. Department of the Treasury has suggested that $600 billion represents a conservative estimate of the amount of money laundered each year, and some U.S. law makers believe that, not only does the amount lie somewhere between $500 billion and $1 trillion, but that half is being laundered through U.S. banks."
