Let's start with credit unions, which are supervised by the National Credit Union Administration (NCUA). Created in 1970, the NCUA charters, supervises, regulates, and provides as much as $250,000 in deposit insurance to "millions of account holders in all federal credit unions and the overwhelming majority of state-chartered credit unions."
Next, FDIC insurance is only for cash deposits. Other financial instruments that are not cash -- like stocks, bonds, mutual funds, annuities, cryptocurrencies, and others -- are ineligible for insurance.
Lastly, there's that $250,000 limit, which means only $250,000 of an individual's deposits at a single institution are insured. Have more than $250,000 you want insured? One solution (if appropriate) is to hold deposits in joint accounts -- remember, it's per person.
Who pays for the FDIC?
While it is part of the federal government, the FDIC doesn't receive any appropriations from Congress, so it's not funded by taxes. Instead, it's funded by insurance premiums paid by member institutions.
