Without deposits they don’t have money to loan and they are no bank at all.
If what you said was true then a bank run would make a bank stronger instead of taking it out.
So I say Nonsense to what you said.
Banks don't loan deposits.
A BANK RUN == TAKING OUT THE DEPOSITS
If you knew a bit more about accounting and banking your advice would be worth zero. Loans are assets on a banks financial statement because they generate income. When there is a run on the bank and deposits leave they become insolvant because they cannot pay the later to leave unless they can borrow or raise equity. Stick to your day job.
