What type of financial institution does not offer federally insured deposit accounts?

Non-depository financial institutions are the correct choice because they do not take deposits from customers in the traditional sense and therefore do not offer accounts that are federally insured. Unlike commercial banks, credit unions, and investment banks, which may offer various deposit accounts, non-depository financial institutions provide services such as investments, insurance, and loans without holding traditional deposits.

Commercial banks and credit unions are specifically designed to offer deposit accounts and are backed by federal insurance to protect depositors. Investment banks, while also not focusing on deposit accounts, typically deal with securities and other investment products rather than direct deposits. This distinction helps clarify why non-depository financial institutions stand apart in the context of federally insured deposit accounts.
