All reputable banks in the U.S. are insured by the FDIC (Federal Deposit Insurance Corporation), which both insures deposits and provides consumer information about banks.
The banking regulatory agency FDIC allows some banks that have more capital to offer interest rates about the national average.
Keep in mind that, depending on your investment choices, your funds may not be FDIC insured.
If an FDIC insured bank or savings association fails, depositor's account balances are protected up to specific limits based on the type of account.
The more you know about FDIC insurance protection, the better prepared you will be if your bank or savings association fails.
