Banks don't loan deposits.
Right. You don't own the deposited money, the banks own it and you have a share of the bank's value. When you deposit money, you get an IOU. If the bank runs into trouble, the FDIC may cover you to a certain extent but a promise is, just a promise until you're made whole.
Of course they DO-—but NOT all deposits.....
Where do you think they get $$$$$$$ to loan out???
