Banking law is defined as the set of rules governing banking operations and those who carry them out professionally by credit institutions. It is a subdivision of commercial law belonging to the branch of private law. Banking law lists all the rules relating to banking transactions on the one hand and the relations between the actors on the other.

In Switzerland, the rules are issued by the State and the Swiss Bankers Association. The main purpose of the banking framework is to protect consumers, in particular through the establishment of accounts, the authorisation to operate or the rules concerning own funds.
