A Bank is a business that provides banking services for profit. Traditional banking services include receiving deposits of money, lending money and processing transactions. Some banks (called Banks of issue) issue banknotes as legal tender. Many banks offer ancillary financial services to make additional profit; for example: selling insurance products, investment products or stock broking.
Banks require permission to trade: authorization to trade is granted by bank regulatory authorities and provide rights to conduct the most fundamental banking services such as accepting deposits and making loans. There are also financial institutions that provide banking services without meeting the legal definition of a bank (see banking institutions). Traditionally, a bank generates profits from transaction fees on financial services and from the interest it charges for lending. In recent history, with historically low interest rates limiting banks' ability to earn money by lending deposited funds, much of a bank's income is provided by overdraft fees and riskier investments.
