Interpreting Bond Yields: Suppose You Buy A 7 Percent Coupon

1. Interpreting Bond Yields. Suppose you buy a 7 percent coupon, 20-year bond today when it’s first issued. If interest rates suddenly rise to 15 percent, what happens to the value of your bond? Why?
When interest rates increase to 15 percent, the value of your existing 7 percent coupon bond will decline. This is because newly issued bonds will offer a 15 percent yield, making your lower-yielding bond less attractive to investors. To compensate for the lower coupon rate compared to the new prevailing market rates, the price of your bond must decrease below its face value. Investors will only be willing to purchase your bond at a discount to match the higher yields available elsewhere in the market, indicating an inverse relationship between market interest rates and bond prices.

Understanding the Dynamics of Bond Prices and Yields
The relationship between bond prices and market interest rates is fundamental in fixed-income investing. When an investor purchases a bond, they are essentially lending money to the issuer in exchange for periodic interest payments—coupon payments—and the return of principal at maturity. The yield on a bond, primarily the yield to maturity (YTM), reflects the annualized return an investor expects if the bond is held until maturity, considering purchase price, coupon payments, and face value.
The first scenario deals with the impact of rising market interest rates on bond valuations. Initially, purchasing a 7 percent coupon, 20-year bond at issuance implies a fixed interest income of 7 percent annually based on face value. However, if market rates increase to 15 percent, newly issued bonds will provide higher coupon payments, making them more attractive. Consequently, the market value of existing bonds with lower coupons must decline to offer a comparable effective yield. This inverse relationship is central to bond pricing and is rooted in the fact that bonds are valued as the present value of their future cash flows discounted at current market rates.
The decline in bond price when interest rates rise is an important risk for bondholders. It reflects the market's adjustment to new conditions, and it explains why bondholders may face capital losses if they sell bonds when rates have increased. Conversely, if rates fall, existing bonds with higher coupons become more valuable, leading to capital appreciation. The sensitivity of bond prices to interest rate changes depends on several factors including time to maturity, coupon rate, and yield.
In practice, this inverse relationship underpins many strategies in fixed-income management, such as duration matching and immunization, designed to hedge against interest rate risk. Understanding these mechanics allows investors to better manage their portfolios and anticipate how market movements might impact bond investments.
