Understand the intricate relationship between bond prices and interest rates, including how bond yields are impacted and examples with calculations. Learn to master bond investment strategies in varying interest rate environments.
Understanding the relationship between bond prices and interest rates is crucial for investors and finance professionals, especially those preparing for the Canadian Securities Course (CSC) exam. This chapter delves into the fundamental inverse relationship that exists between bond prices and bond yields, which fluctuate with prevailing interest rates.
The cornerstone of bond pricing is the inverse relationship between bond prices and bond yields. When interest rates rise, bond yields also increase, leading to a decrease in bond prices. Conversely, when interest rates fall, bond yields decline, leading to an increase in bond prices. This inverse relationship can often be succinctly described using the following formula:
Let’s take a closer look at the impact of interest rate changes on the price of a bond with examples.
The following table aims to provide clarity on how changes in interest rates affect the bond pricing process:
| % Yield | % Change Yield | Price | Price Change | % Price Change |
|---|---|---|---|---|
| 3% | 0 | 100.00 | 0 | 0 |
| 4% (1% Increase) | +33.33* | 95.51 | –4.49 | –4.49 |
| 2% (1% Decrease) | –33.33 | 104.74 | +4.74 | +4.74 |
defined as \(Change in Yield\): \( \frac{\text{Ending Value} - \text{Beginning Value}}{\text{Beginning Value}} \times 100; (0.04-0.03)/(0.03) \times 100 = 33.33%\)
The coupon rate of a bond remains constant over its lifetime regardless of price movements. However, when interest rates change, the bond’s yield must adjust accordingly. For yield to increase beyond the coupon rate when interest rates rise, the price of the bond must fall. Conversely, for yield to decrease below the coupon rate when interest rates fall, the price of the bond must rise.
If a bond’s coupon rate remains constant, when interest rates rise, the bond price must decrease, prompting a rise in bond yields. Conversely, if interest rates fall, the bond price will need to increase to accommodate the fallen yield until bond maturity.
Q1: What happens to bond prices when interest rates rise? A1: When interest rates increase, bond prices generally decrease which in turn increases the yield.
Q2: Why is there an inverse relationship between bond prices and yields? A2: This inverse relationship happens because the bond’s fixed coupon payments become more or less attractive compared to the new interest rates environment, forcing prices to adjust.
Coupon Rate: The annual interest rate paid by the bond’s issuer to the bondholder.
Yield to Maturity (YTM): The total return anticipated on a bond if held until it matures.
