The files – obtained through an international collaboration of news outlets, including the Guardian, the French daily Le Monde, BBC Panorama and the Washington-based International Consortium of Investigative Journalists – reveal that HSBC’s Swiss private bank:
• Routinely allowed clients to withdraw bricks of cash, often in foreign currencies of little use in Switzerland.
• Aggressively marketed schemes likely to enable wealthy clients to avoid European taxes.
• Colluded with some clients to conceal undeclared “black” accounts from their domestic tax authorities.
• Provided accounts to international criminals, corrupt businessmen and other high-risk individuals.
The HSBC files, which cover the period 2005-2007, amount to the biggest banking leak in history, shedding light on some 30,000 accounts holding almost $120bn (£78bn) of assets.
