Do you have some reliable source about it?
(NOT a "look at it logically" or "here's how my health insurance works, why would the FDIC be different", or "do your own research" or anything else that's some random internet comment - I'm looking for real meat about this claim).
Any losses to the Deposit Insurance Fund to support uninsured depositors will be recovered by a special assessment on banks, as required by law.
In other words, if the FDIC's current funds can't cover the bill, an extra fee will be levied on banks to make up for it.
The problem, as it were, isn't some lurking or hidden loss, it's arguably that these answers aren't currently available and we don't have the slightest idea in the public what will happen if profits result from the bailout venture. This shouldn't be a "heads-I-win-tails-you-lose" redux.
The FDIC's current funds were $128.2 billion on December 31 2022
SVD had ~$200 billion of deposits December 31 2022 - but obviously had significant withdrawals prior to being taken over. Likely < 100 billion remained.
Beyond the special assessment, they almost certainly need to raise a new assessment to cover $250k+ deposits. Full insurance can't be on a discretionary basis.
