If Banks debt > money+interest lent out At the same time then maybe the bank is insolvent However all debt typically isn't all due at the same time just like money lent out isn't paid back all at the same time. This stuff is spread and balanced out so that ideally the bank has little liquid assets it needs, it is then able to borrow and lend out the maximum amount of money it can. That is if it can lend money at a higher rate than it borrows it's making money. Otherwise it ain't.
