In reality what a shrinkage of the deposits with that size means when you are using fractional reserve banking is that the ability to finance other things have gone down 90-95 times as much depending on what sorts of credits you are talking about. With the ways the banks have been faking numbers it could in reality be 200 times as much. So if customers pull one billion in deposits it means that people looking for financing gets a much harder time to find it. 90-95 billions less. Imagine how this affects the way investments are made. This will raise interest rates extremly if it’s not kept down artificially by the eurozone by pumping new money into the system.
