Some of the money that people deposit into a bank eventually becomes an injection into the economy when the bank makes loans. 
In the Banks . there are some people who deposit money and there are some people who borrow money.
The bank will use the money that people deposit to give a loan to the one that want to borrow the money. so technically, people who deposit money are the one who make an injection within the economy.

Hope this helps! Have a good day!
