Bank-client confidentiality ( Art. 47 of the Banking Act, Art. 43 of the Stock Exchange Act) establishes professional confidentiality comparable to that of doctors, lawyers or priests. Its aim is always to protect personal privacy.
Discretion remains part of Swiss banks’ DNA to this day. This section explains the extent of privacy protection today and the limits that have been placed upon it.
Having one’s privacy protected is a human desire and citizens right. This protection is, however, not absolute. It ends where the law places limits on it. As a result, personal privacy enjoys constitutional protection in Switzerland, just as does, for example, personal freedom, freedom of religion and conscience, or freedom of speech.
