Well I did another look and found this link on DB, yes they have derivative exposure of between $55 and $75 Trillion. How is this possible?
Whatever the exposure it is bad and Citi along with Barclays are in trouble also. So if DB is not propped up it could take down the top 10 to 15 banks in the world. So my opinion is that DB will not be allowed to fail.
The key question is: Can DB be saved once the dominoes start falling? Germans still remember the horrible inflation of the Weimar Republic. To bail out DB, the Germans would have to create trillions of Euros via the ECB - leading to what could end up being another hyper-inflation....
