How secrecy could shield an account
A bank account is useful to a government only if it can be found and connected to its owner. In the 1930s, as Nazi Germany stripped Jews of rights and property, keeping assets outside German reach could matter—but so could keeping German authorities from learning where those assets were held.
Switzerland’s 1934 Banking Act made it a criminal offense for bank employees to disclose client information. That gave a Swiss bank a legal reason to refuse requests for account details, making it harder for a foreign government to identify and seize assets held in Switzerland. The bank itself still knew who its clients were: secrecy meant protection from disclosure, not an account with no owner.
Protection came with a tradeoff
For people facing persecution, concealment could help preserve savings beyond the persecuting state’s immediate control. But the same barrier to disclosure could also frustrate tax authorities and other investigations. The law did not guarantee that an account would remain untouched in every circumstance, nor was protecting Jewish assets its only political or economic context.
That tension is central to the legacy of Swiss secrecy: a rule that could serve people trying to shield property from a predatory government also made it harder for outsiders to see who held wealth—and why.
