All of them within the $250k FDIC insured limit.

I know this is the case because this is how I would do it.

The banks 'go under', but through quick accounting, and "just in the nick of time" the regime here and abroad (israel) get their largest accounts out, or are made whole.

Regulators come in so it is "out of the banks hands", only after.
The bank then "bails-in" with those customers accounts.

FDIC kicks in, and restores those accounts.

Then they get to double-dip, and the american people get blamed.
