You are confused. There is no such thing as a loanable funds market. The guy at the bank making the loan does not call the other guy at the bank to look in the safe and see if the funds exist to loan out. Doesn't work that way.

By and large, the only thing stopping a bank from 'creating money' or making a loan is the willing and able consumers.
