Sorry for late reply, yup who knows there are more banks as mentioned in worst situation, if a bank run should follow, there will be a collapse.
But Fed I heard has ade arrangements for banks to borrow so they won't face any shortage of cash and the investors have already shifted deposits to bigger banks, which will be able to handle this stress.
The problem was with these banks puting customer deposits on these instruments for long term, so liquidity was locked so to say.
Nice hearng from you, been a while!!!
