The required amount of the bank’s capitalization can be as low as US$ 500,000 (but that’s rare). Many offshore banks have capitalizations of 3 to 5 million dollars. If you would like to open a bank in a large country, you may have to bring US$ 25,000,000 or more. Besides, you have to take additional costs into account. You have to register the banking company, pay the license fee, hire qualified personnel, install expensive banking software, and so on.
