A bank investment is a financial product that is offered by a bank and involves the depositing of money into an account in exchange for interest payments. A LEVEE is a type of bank investment that involves depositing money into a savings account with a fixed rate of return. The money deposited into the account is then used to fund loans and other investments, and the investor receives interest payments from the bank. This type of investment is typically low-risk and provides a steady stream of income.
