If your bank is having liquidity issues then it’s long past time to get your needed money out. FDIC insurance paybacks can take months or more to happen.
But! The FDIC is not just insurance. It’s also a framework for risk management including liquidity risk. Banks have pretty detailed playbooks on how to manage liquidity risk that are routinely audited. It is therefore pretty rare for any US bank to have such issues and when they do it’s because they were cooking the books.
Reading through those I couldn’t actually find any banks that had evidence of liquidity issues. And the longest I saw for the fdic to get depositors access to their funds was the weekend.
Most of them don’t even tap FDIC insurance they just hand the depositors over to a different bank.
