In the Insolvency and Bankruptcy Board of India’s exam for Registered Valuer for the Securities and Financial Asset class, Bond Duration is part of Valuation Application chapter from which around 2-3 MCQ are expected relating directly to Bond Duration concept or other concepts related to this. Therefore, for the purpose of Registered Valuer exam of IBBI, one need to understand this concept of Bond Duration including the practical or numerical problems on this properly so that MCQ in exams can be solved without any error.

Bond duration is a way of measuring how much bond prices are likely to change if and when interest rates move. In more technical terms, bond duration is measurement of interest rate risk. Understanding bond duration can help investors determine how bonds fit in to a broader investment portfolio.

It’s almost impossible to hear or read about the bond markets without coming across the word “duration.” But what does this term mean? And how does it affect your savings?

First, it’s important to understand how interest rates and bond prices are related. The key point to remember is that rates and prices move in opposite directions. When interest rates rise, prices of traditional bonds fall, and vice versa. So if you own a bond that is paying a 3% interest rate (in other words, yielding 3%) and rates rise, that 3% yield doesn’t look as attractive. It’s lost some appeal (and value) in the marketplace.

Duration is measured in years. Generally, the higher the duration of a bond or a bond fund (meaning the longer you need to wait for the payment of coupons and return of principal), the more its price will drop as interest rates rise.

So how does this actually work? As a general rule, for every 1% increase or decrease in interest rates, a bond’s price will change approximately 1% in the opposite direction for every year of duration.      

For example, if a bond has a duration of five years and interest rates increase by 1%, the bond’s price will decline by approximately 5%. Conversely, if a bond has a duration of five years and interest rates fall by 1%, the bond’s price will increase by approximately 5%.

Understanding duration is particularly important for those who are planning on selling their bonds prior to maturity. If you purchase a 10-year bond that yields 4% for $1,000, you will still receive $40 dollars each year and will get back your $1,000 principal after 10 years regardless of what happens with interest rates. If, however, you sell that bond before maturity (or if you are invested in a fund that buys and sells bonds while you own it) then the price of your bonds will be affected by changes in rates.

There is a common perception among many investors that bonds represent the safer part of a balanced portfolio and are less risky than stocks. While bonds have historically been less volatile than stocks over the long term, they are not without risk.

The most common and most easily understood risk associated with bonds is credit risk. Credit risk refers to the possibility that the company or government entity that issued a bond will default and be unable to pay back investors’ principal or make interest payments.

Bonds issued by the US government generally have low credit risk. However, Treasury bonds (as well as other types of fixed income investments) are sensitive to interest rate risk, which refers to the possibility that a rise in interest rates will cause the value of the bonds to decline. Bond prices and interest rates move in opposite directions, so when interest rates fall, the value of fixed income investments rises, and when interest rates go up, bond prices fall in value.

If rates rise and you sell your bond prior to its maturity date (the date on which your investment principal is scheduled to be returned to you), you could end up receiving less than what you paid for your bond. Similarly, if you own a bond fund or bond exchange-traded fund (ETF), its net asset value will decline if interest rates rise. The degree to which values will fluctuate depends on several factors, including the maturity date and coupon rate on the bond or the bonds held by the fund or ETF.

Using a bond’s duration to gauge interest rate risk

While no one can predict the future direction of interest rates, examining the “duration” of each bond, bond fund, or bond ETF you own provides a good estimate of how sensitive your fixed income holdings are to a potential change in interest rates. Investment professionals rely on duration because it rolls up several bond characteristics (such as maturity date, coupon payments, etc.) into a single number that gives a good indication of how sensitive a bond’s price is to interest rate changes. For example, if rates were to rise 1%, a bond or bond fund with a 5-year average duration would likely lose approximately 5% of its value.

Duration is expressed in terms of years, but it is not the same thing as a bond’s maturity date. That said, the maturity date of a bond is one of the key components in figuring duration, as is the bond’s coupon rate. In the case of a zero-coupon bond, the bond’s remaining time to its maturity date is equal to its duration. When a coupon is added to the bond, however, the bond’s duration number will always be less than the maturity date. The larger the coupon, the shorter the duration number becomes.

Generally, bonds with long maturities and low coupons have the longest durations. These bonds are more sensitive to a change in market interest rates and thus are more volatile in a changing rate environment. Conversely, bonds with shorter maturity dates or higher coupons will have shorter durations. Bonds with shorter durations are less sensitive to changing rates and thus are less volatile in a changing rate environment.

From this piece of information, you must have realised by now that how important this concept of Bond Duration is from the point of view of IBBI registered valuer Examination. Therefore, Student’s unfamiliarity with this concept, its application and rationale assuming that these areas are complex would not be appreciated and may cost the aspirant a lot. Therefore, I would like to urge you all to study this concept precisely and adequately. You can easily score those 1 to 3 marks in valuer examination that will make the difference between passing and failing.

What is eventually important for you is to study strategically and work on your weak areas with complete dedication so that you could pass the IBBI registered valuer examination. And for passing that examination with a minimum of 60% marks, these small and easy areas make a lot of difference.
