Quote from neutrino:
The problem with the fractional reserve banking is that you have the right to withdraw your money at any time. We know that we can't do that all at the same time, and we know that we take a risk of a bank run. But noone forces you to keep your money in an interest earing account. You can put it in a safe deposit box, pay the annual fee, and you can feel secure about your holdings.
Correct me if I am wrong, but you can't write checks against cash held in your safety deposit box. Hence it is illiquid.
I think most of you have no idea how a non-fractional reserve bank would operate. On-demand deposits are charged a fee and simply held for safekeeping. The money that the bank lends out is the money given to the bank by investors. For example, investors would give money to a bank and have it locked up, like a CD, for a certain return. The bank would then lend that money out for a higher return. Pretty much hard money lending.
