A Money ‘Black Hole’: Rich Hide At Least $21 Trillion In Tax Havens, Study Shows

Thanks to lax international tax rules the world’s super rich have siphoned at least $21 trillion — more than 50 percent larger than the entire U.S. economy — into secretive tax-free havens, according to a study by UK campaign group Tax Justice Network.

The report by James Henry, a former chief economist at international consultancy McKinsey & Co., shows how with the help of private banks the money has flowed into countries such as Switzerland and the Cayman Islands.

“We’re basically talking about a black hole in the world economy,” Henry told NBCNews.com.

The figure of $21 trillion in off-shore funds is conservative and the true sum could be as high as $32 trillion, Henry said.
