Swiss banks are the most popular source of cash and wealth for the world's richest people. This is not a one bank. According to Switzerland's banking policy, about 250 banks and financial institutions operating under the Swiss Federal Banking Commission are collectively known as Swiss Bank. The Swiss bank is famous for storing tax evaded illicit assets of unscrupulous corrupt rich people in different parts of the world. Banks in Switzerland have been conducting these activities for over 300 years. The main feature of Swiss Bank is the minimum risk of capital and the highest confidentiality of the customer. Customers are guaranteed this privacy under a Swiss law of 1934. Their customer relationship with Swiss Bank is much like that of lawyers and their clients. A minimum of 100,000 USD is required to open a Swiss bank account.
