Rich individuals and their families have as much as $32 trillion of hidden financial assets in offshore tax havens, representing up to $280 billion 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.
The research was carried out for pressure group Tax Justice Network, which campaigns against tax havens, by James Henry, former chief economist at consultants McKinsey & Co.
