Coupon rate and bond yield are two key phrases you will encounter when investing in bonds. They are not the same, yet they both assist you in understanding the potential return on a bond. Bond yield indicates the real return based on the bond's purchase price, whereas coupon rate indicates the fixed interest a bond pays. Assume you purchased a ₹1,000 bond at a discounted market price of ₹800 with a 5% coupon rate. Because that same ₹50 payment now makes up a greater share of your smaller ₹800 investment, your bond return rises to 6.25%. Comprehending the distinction between bond yield and coupon rate enables investors to make more educated and superior investing choices.
What is the Coupon Rate?
The set annual interest that a bond issuer pays to the bondholder is known as the coupon rate. It is computed as a percentage of the bond's face value and usually stays the same for the duration of the bond.
For instance, regardless of fluctuations in the bond's market price, an investor will receive ₹50 annually if the bond has a face value of ₹1,000 and a 5% coupon rate.
What is Bond Yield?
The real return an investor receives from a bond based on its current market price is referred to as bond yield. Bond yield varies over time as bond prices do, in contrast to the coupon rate.
For instance, let's say the same bond with a face value of ₹1,000 and an annual interest rate of ₹50 is purchased for ₹900 rather than ₹1,000. Since the investor is making ₹50 on a smaller investment, the yield in this scenario will be more than 5%. Conversely, the yield will be less than 5% if the bond is purchased at ₹1,100
Difference Between Coupon Rate and Bond Yield
The table below shows the difference between coupon rate and bond yield.
Basis | Coupon Rate | Bond Yield |
Meaning | The fixed interest rate paid by the bond issuer to the investor. | The actual return an investor earns from a bond based on its current market price. |
Calculation Basis | Calculated on the bond’s face value. | Calculated using the bond’s current market price. |
Change Over Time | Usually remains constant until the bond matures. | Changes when the bond price fluctuates in the market. |
Market Impact | Not affected by market price changes. | Directly affected by changes in interest rates and bond prices. |
Purpose | Shows the interest income promised by the bond issuer. | Helps investors measure the real return from buying a bond at its current price. |
Impact of Interest Rate Changes on Bond Prices and Yields
Interest rate and bond prices have an inverse relationship. When the interest rate changes on bond prices and yields, then the following conditions might take place:
- As the interest rates go up, the current bonds with low coupon rates become unappealing.
- This will lead to a fall in bond prices and an upward increase in yields.
- When interest rates are low, those bonds which have a higher coupon rate will be more appealing. This increases the prices of bonds and lowers the yields.
What Investors Should Keep in Mind
The following are the key points that investors should keep in mind before investing.
- It is important for them to first understand the difference between coupon and yield before making any investment decision.
- Determine the prevailing market value of the bond because it determines the realised return or yield.
- Take interest rate trends into account, since an increase or decrease in the interest rates may alter the bond price and yield.
- Assess the maturity rate of the bond to determine the length of time that the investment will be held.
- Evaluate the quality of credit by the issuer to minimise the credit risk.
- Compare multiple bonds to choose the option that offers a suitable balance between return and risk.
Conclusion
Knowing the difference between coupon rate and bond yield is significant for assessing bond investments. Coupon rate is the constant rate of interest charged on the face value of the bond, while bond yield is the actual rate of return in the current market price of the bond. Because the value of the bond varies with the interest rate trends, the yield might vary with the coupon rate in the long term. By comparing the values of the coupon rate and the yield, the investors are more likely to compare bonds, evaluate the potential of returns and make better decisions by investing in fixed-income investments.
FAQs on Difference Between Coupon Rate Vs Bond Yield
What is the difference between coupon rate and bond yield?
Bond yield fluctuates as bond prices vary in the market. The coupon rate is fixed, whilst the yield varies with the market price of the bond.
Why is bond yield different from the coupon rate?
Yes, the yield of the bond can be increased when the bond is bought at a lower price than its nominal value. The investors in this instance have a greater effective return.
