If you have a bank account, such as a savings account or a checking account, at a US bank, it is likely insured by the Federal Deposit Insurance Corporation, a federally-chartered organization that protects bank accounts in the event that the bank goes bankrupt or runs into other major issues. SIPC protects money that you may have in investment accounts. It doesn't protect you against the value of your accounts, such as stocks and mutual funds, from going up and down, but it does make sure that if the investment company goes bankrupt or runs into major issues, you can still redeem the money in your investment accounts.
