The Federal Act on Banks and Savings Banks is a Swiss federal law and act-of-parliament that operates as the supreme law governing banking in Switzerland. Although the federal law has only been amended seven times, it has been revised multiple times to limit and expand its banking secrecy provisions since its ratification. The banking secrecy provisions in the Federal Act are additionally enforced through multiple civil codes in the federal Swiss Civil Code and locally through cantonal law. In December 2017, the Swiss parliament launched a standing initiative and expressed an interest in formally embedding banking secrecy within the Swiss Federal Constitution rendering it a federally-protected constitutional right.
