Switzerland is the number one banking destination for international clients for several reasons:

• Political stability - Switzerland has not been at war with another country since 1505
• Safety - Swiss banks are extremely safe. There is only an extremely remote chance of losing money deposited in a Swiss bank.
• Stable currency backed by gold - the Swiss francs is probably the most stable currency in the world
• Excellent quality of banking services - internet banking, sophisticated investment services, multiple currency accounts and many other high-level services are available in Swiss banks.
• Privacy - if you are not a criminal, it is almost impossible for anybody to get any information about you out of a Swiss bank
