The NCUSIF does not insure the money individuals invest in stocks, bonds, municipal bonds, or other securities such as mutual funds (including money market mutual funds, and mutual funds that invest in stocks, bonds and other securities); annuities (which are contracts underwritten by insurance companies that guarantee income in exchange for a lump sum or periodic payment); or insurance products such as automobile and life insurance. The above applies even if these products were purchased at a federally-insured credit union or through an affiliated broker/dealer/insurance agent that is offering these products on behalf of a federally-insured credit union.

The NCUSIF does not insure U.S. Treasury bills, bonds, or notes. These are backed by the full faith and credit of the U.S. Government.

The NCUSIF does not insure valuables in safe deposit boxes. These contents, however, may be covered by a box holder's personal homeowner's insurance
