In popular culture, there is nowhere safer to stash your cash than the vault of a Swiss bank. From thrillers to spy novels, Swiss bankers are depicted as discreet men in suits who know which questions not to ask.

Switzerland dismisses such stereotypes as lazy and outdated. But its reputation as one of the premier tax havens has not come out of nowhere.

Suisse secrets is a global journalistic investigation into a leak of data from the Swiss bank Credit Suisse. It comprises more than 18,000 bank accounts that were leaked to Süddeutsche Zeitung by a whistleblower who said Swiss banking secrecy laws were «immoral». The data, which is only a partial capture of the bank’s 1.5 million private banking clients, is linked to more than 30,000 Credit Suisse clients. The leak includes personal, shared and corporate bank accounts – holding, on average, 7.5m Swiss francs (CHF). Almost 200 accounts in the data are worth more than 100m CHF, and more than a dozen are valued in the billions. While some accounts in the data were open as far back as the 1940s, more than two-thirds were opened since 2000.
