What is a certificate of deposit (CD) essentially considered as?

A certificate of deposit (CD) is essentially considered a loan to a bank. When an individual purchases a CD, they are essentially lending their money to the bank for a fixed period of time, ranging from a few months to several years. In return for this loan, the bank typically offers a higher interest rate than regular savings accounts as compensation for the individual locking their funds away for that specified duration.

The relationship between the depositor and the bank is that of a borrower and lender, where the depositor is offering their funds to the bank, which then utilizes these funds to lend to other customers or invest. The fixed term and interest make CDs a low-risk, predictable savings option, and the Federal Deposit Insurance Corporation (FDIC) often insures them, adding a layer of security for the depositor.

In contrast, the other options represent different financial instruments: investments in stocks involve equity ownership in a company, insurance policies provide protection against risks, and government bonds are debt securities issued by governments to raise funds. Each of these options serves different purposes and operates under distinct principles, making them unsuitable to define a CD.
