Eh FWH, go back and check your facts. I think you've got the recipient information wrong. The deposits went back to the original holders of the deposits. Not to the FDIC.
Think about it, you have $1m in deposits with a bank. The FDIC's exposure is $250/500k if the bank fails. The rules change, and the bank decides that all deposits of $1m are too 'expensive' for them to maintain.
So they tell the depositor that their business, of a $1m account, isn't cost-effective and to please withdraw and move their monies elsewhere.
Nowhere does the bank just give the FDIC that $1m.
(a) It's not theirs to give.
(b) While the FDIC rules and subsequent regulations may be the cause, it's not that the FDIC got the monies.
