Bond refers to a security issued by a company, financial institution or government which offers regular or fixed payment of interest in return for borrowed money for a certain period of time.
A bond is like a loan: the issuer is the borrower (debtor), the holder is the lender (creditor), and the coupon is the interest. Bonds provide the borrower with external funds to finance long-term investments, or, in the case of government bonds, to finance current expenditure. Certificates of deposit (CDs) or commercial paper are considered to be money market instruments and not bonds. Bonds must be repaid at fixed intervals over a period of time.
By purchasing a bond, an investor loans money for a fixed period of time at a predetermined interest rate. While the interest is paid to the bond holder at regular intervals, the principal amount is repaid at a later date, known as the maturity date.
