I work for CS in their Zurich HQ..They have trillions in assets but all this bad publicity is like a self fulfilling prophecy..Everyone is being spooked and pulling out their money, all at once this causes liquidity issues which then causes it to have to stop withdrawals, which then causes panic like a snowball effect, as they cannot sell assets (like real estate or another part of the company) as quick as Dave, George and Mildred want their nest eggs. The bank is too big to fail so won't be allowed too, but all these whispers are causing the problems.
