Banks are also a great source of capital for account holders or those who have a relationship with the bank by taking out loans for significant capital purchases like house mortgages, automobile loans, home equity loans, small business loans, and large commercial loans of corporations. Banks also manage the transactions of credit and debit cards. In short, banks provide for us the place to save money, the means to spend that money, and wholly new sources of money by way of loans, which provides the fuel of our economy.
