Quick Definition
Bond interest refers to the periodic payments made by the bond issuer to the bondholder as compensation for lending their capital. It represents the cost of borrowing for the issuer and the return on investment for the bondholder.
The interest rate, often called the coupon rate, is a key feature of a bond and is usually expressed as a percentage of the bond's face value, or par value. This rate determines the amount of each interest payment, which is typically paid semi-annually or annually.
Understanding bond interest is crucial for investors because it directly impacts the total return they receive from holding the bond. The higher the coupon rate, the more interest income the investor will earn over the life of the bond.
From the issuer's perspective, the bond interest rate is a significant factor in determining the overall cost of financing. A lower interest rate means lower borrowing costs, making it more attractive to issue bonds.
Bond interest payments are considered a fixed income, offering a predictable stream of cash flow for investors. This predictability makes bonds attractive to those seeking stable returns and less volatility compared to stocks.
The market price of a bond and its interest rate have an inverse relationship. When interest rates in the market rise, the price of existing bonds with lower coupon rates tends to fall, and vice versa.
Changes in bond interest rates can also reflect broader economic conditions. For instance, rising interest rates may indicate inflation or a tightening of monetary policy by central banks.
Bond interest is a fundamental concept in fixed-income investing and a vital tool for corporations and governments to raise capital. It provides a mechanism for borrowers and lenders to connect in the financial markets.
