Banking secrecy is proverbial, especially in Switzerland, and has been the model for more recent off-shore banking services seeking depositors internationally. However, secret bank accounts can facilitate tax avoidance, tax fraud, the financing of organized crime and international terrorism, and embezzlements by reigning monarchs or despots of their governments funds.
Legends of secret fortunes in Swiss banks are connected with the SS and Adolf Hitler, with Shahs and Sheiks, with the Mafia, with the CIA, and with the Vatican, to name a few.
