Insured deposits only
I have stressed several times to ensure that any funds that you have in any bank be under the FDIC insurance limit.
It looks the bank closures are starting. This is what the press release for a closed bank looks like. This is what the notice telling you that you may not get amounts over $100k back looks like.
Better yet, if there are signs the bank you belong to is in trouble, move your money elsewhere and avoid the hassle.
