So there really is a problem then?
You don't tell a guy on the brink of a heart attack that everything is fine with his heart as long as he doesn't exert himself, or frankly even move, and just lays in bed all day.
I think at this stage, nobody is going to believe that the authorities have it under control once a problem is actually identified.
The thing to realize is that bank solvency only matters if somebody shows up wanting his cash, and the cash isn't there - or if regulators force you to mark stuff to a cratering market. When it comes to TBTF institutions, the Fed will provide unlimited liquidity to mask any problems and things will get worked out behind the scenes.
If there was a problem so massive that it couldn't be concealed, the market would certainly have wind of it and we'd be talking about whatever the root cause is.
