A Bank Consent Letter is a critical document in Swiss banking operations, required whenever there is a need to share protected banking information with third parties while maintaining compliance with Switzerland's strict banking secrecy laws. This document becomes necessary in various scenarios, such as during audits, regulatory investigations, or when establishing relationships with other financial institutions. The letter must carefully balance the need for information sharing with the fundamental principles of Swiss banking secrecy, as established in Article 47 of the Swiss Federal Banking Act. It requires precise drafting to ensure it covers the specific scope of authorized disclosure while providing adequate protection for both the bank and the client under Swiss law. The document must also align with Swiss data protection regulations and financial market supervision requirements.
