Fixed-income securities, such as bonds, are essentially IOUs issued by governments and corporations. When you invest in a bond, you’re lending money to the issuer in exchange for regular interest payments and the return of your principal at maturity. The interest payment is known as the coupon, and the coupon rate is the fixed annual interest rate paid on the bond’s face value (par value).
How Coupon Rates Work
- Example: If you buy a bond with a face value of ₹1,000 and a coupon rate of 8%, you’ll receive ₹80 in annual interest payments.
Key Points About Coupon Rates
- Fixed vs. Yield: The coupon rate remains constant, but the bond’s yield fluctuates based on its market price.
- Higher Coupon = Higher Income: Bonds with higher coupon rates provide greater annual interest.
- Beyond Coupon Rates: Investors should also consider credit ratings, maturity dates, and call provisions before investing.
Historical Context: The Origin of “Coupon” Rates
The term “coupon” dates back to the 19th century when bonds were issued as physical certificates with detachable coupons. Investors would clip these coupons and present them to the issuer to receive their interest payments. This practice gave rise to the term “coupon rate.”
