A bank is a business that provides financial services, usually for profit. Traditional banking services include receiving deposits of money, lending money and processing transactions. A commercial bank accepts deposits from customers and in turn makes loans based on those deposits. Some banks (called Banks of issue) issue banknotes as legal tender. Currently in most jurisdictions commercial banks are regulated and require permission to operate. Operational authority is granted by bank regulatory authorities and provide rights to conduct the most fundamental banking services such as accepting deposits and making loans.
