One Monday in March last year, an announcement by the US justice department caught the attention of a former employee of the Swiss bank BSI. BSI’s bosses had agreed to violate the first rule of Swiss banking. To escape prosecution for abetting tax evasion, the bank would disclose the names of its clients and reveal the tricks it had used to hide their wealth.
The former BSI employee, who asks to be referred to only as Andrea, had worked in the bank’s UK office on Cheapside in the heart of the City of London. In 2008, Andrea was among the industry insiders who were starting to worry about London’s role as a global hub for illicit finance. That September, Andrea had warned the UK’s financial watchdogs that BSI bankers were using secretive techniques that could allow clients to conceal assets, potentially facilitating tax evasion and money laundering. The regulators took no public action against the bank and, as far as Andrea knew, no private action either.
Andrea had been spurred to contact the City’s regulators by a US Senate inquiry into tax evasion. Drawing on the testimony of a whistleblower from UBS, the biggest Swiss bank, the inquiry had exposed some of the chicanery that Swiss bankers used to help their clients hide money. A criminal investigation followed and in 2009 UBS paid a $780m fine to avoid prosecution for complicity in tax evasion.
From there, the prosecutors’ campaign widened dramatically. Credit Suisse, UBS’s main rival, pleaded guilty to conspiring to help Americans evade tax and paid a $2.6bn fine. The onslaught brought down Wegelin, the oldest Swiss bank, which closed its doors in 2013 after 272 years in business. Its final act was to plead guilty to US charges of tax fraud.
