Rich individuals and their families have as much as $32 trillion of hidden financial assets in offshore tax havens, representing up to $280bn in lost income tax revenues, according to research published on Sunday.
The study estimating the extent of global private financial wealth held in offshore accounts - excluding non-financial assets such as real estate, gold, yachts and racehorses - puts the sum at between $21 and $32 trillion.
This amounts to roughly the US and Japanese GDP combined. Roughly 10 million people worldwide have offshore accounts, with 100,000 people owning half of those secreted assets.
“We’re talking about very big, well-known brands - HSBC, Citigroup, Bank of America, UBS, Credit Suisse - some of the world’s biggest banks are invovled…and they do it knowing fully well that their clients, more often than not, are evading and avoiding taxes.”
Much of this activity, Christensen added, was illegal."
