The banks have not been given money to safely tuck away. They have been given surety that's all. That alone improves confidence and hence means that the public feel safer and do not go and get their dosh out all at once which would be armeggeddon. It's like if you deposited your money with a friend and I said don't worry because if they abscond with your dosh I'll give it to you. Tada, armageddon prevented, for now at least, no actual cost. Geddit? In the case where actuall money has been used as in Northern Rock for example then the governenet has effectivell become the major share holder so they have something, they also have an incentive to make it work. Please try and look behind the headlines occasionally.
