That's what happened with Deutsche Bank, when as we reported two weeks ago, the quant fund pulled its cash from Deutsche Bank as a result of soaring counterparty risk, just days before the full - and to many, devastating - extent of the German lender's historic restructuring was disclosed, and would result in a bank that is radically different from what Deutsche Bank was previously (see "The Deutsche Bank As You Know It Is No More").

In any case, now that RenTec is long gone, and questions about the viability of Deutsche Bank are swirling - yes, it won't be insolvent overnight, but like the world's biggest melting ice cube, there is simply no equity value there any more - everyone else has decided to cut their counterparty risk with the bank with the €45 trillion in derivatives, and according to Bloomberg Deutsche Bank clients, mostly hedge funds, have started a "bank run" which has culminated with about $1 billion per day being pulled from the bank.

As a result of the modern version of this "bank run", where it's not depositors but counterparties that are pulling their liquid exposure from DB on fears another Lehman-style lock up could freeze their funds indefinitely, Deutsche Bank is considering how to transfer some €150 billion ($168 billion) of balances held in it prime-brokerage unit - along with technology and potentially hundreds of staff - to French banking giant BNP Paribas.
