The most profitable source of income for banks is non-interest bearing checking accounts. On an overnight basis, Fed Fund Rate is 0.25% and Overnight USD LIBOR is at 0.133%. However these checking accounts pay nothing to customers. So, whenever customers deposits any amount of money, banks easily earn at a minimum 13bps out of it.
That is free income for the bank.
Other lucrative source of income for banks are interest bearing checking account and savings account as they pay peanuts to customers compared to what they can lend out to the interbank market.
