The bank uses the money people have deposited in invests in things, from giving out personal/business loans and mortgages to buying stocks and shares or even buying and selling debt. The profit they make doing this covers the bank's operating cost and interest on your account.

Essentially when you put your money in a bank you are in actuality loaning the bank your money.
