What Causes Bonds To Lose Value In Certain Market Environments?

Bonds are often revered as a safe investment compared to stocks but make no mistake, bonds like other investments are not risk-free, and there are certain market environments where they can lose value. As I write this article in May 2022, the Aggregate Bond Index is currently down 8% year to date. While this is definitely a more extreme year for the bond market, there are other years in the past where bonds have lost value.

How do bonds work?

Bonds in their most basic form are essentially loans paid with interest. Companies, government entities, and countries issue bonds to raise money to fund their operations. When you buy a bond you are essentially lending money to these organizations in return for interest payments and potentially appreciation on the value of the bond. Similar to traditional loans, bonds can default, interest can be fixed or variable, and bonds are issued for varying durations.  But unlike loans, the value of your original investment can fluctuate over the life of the bond.

Bond example

Before we get into all of the variables associated with bonds, let’s first look at a basic example. The US government is issuing a 10-year treasury bond with a 3% interest rate. You buy $10,000 worth of bonds so essentially you are lending the US government $10,000 for a duration of 10 years and during that 10 years, the US government will pay you 3% interest every single year, then after 10 years, the bond matures, the US government hands you back your $10,000.

Credit worthiness

Similar to someone asking to borrow money from you, all bond issuers are not created equal. You have to assess the credit worthiness of the company or organization that is issuing the bonds to make sure that they are going to be able to make their interest payments and return your principal at the maturity date. “Maturity date” is just bond lingo for when the bond issuer has to repay you the amount that you lent to them. When the US government issues bonds, they are considered by the market to be some of the safest bonds in the world because they are backed by the credit worthiness of the United States government. It would be a historic event if the US government were to default on its debt because the government can always print more money or raise taxes to make the debt payments. Compare this to a risky company, that is trying to emerge from bankruptcy, and is issuing bonds to raise capital to turn the company around. This could be viewed as a much riskier investment because if you lend that company $10,000, you may never see it again if the company is unable to emerge from bankruptcy successfully. For this reason, you have to be selective as to who is issuing you the bond.  

Bond rating agencies

Thankfully there are bond rating agencies that help investors assess the credit worthiness of the bond issuer. The two main credit rating agencies are Standard & Poors and Moody’s. Both have grades that they assign to each bond issuer that can range from AAA for the highest quality issuers all the way down to D. It’s important to look at both rating agencies because they may assign different credit scores or in the bond world called “quality ratings” to a bond issuer. But as we learned during the 2008 and 2009 recession, even the bond rating agencies sometimes make the wrong call, so you should complete your own due diligence in assessing the credit worthiness of a particular bond issuer.

Bond defaults

When a company or government agency defaults on its debt it’s ugly. All of the creditors of the company including the bondholders line up to split up whatever’s left, if there is anything left. There could be a number of creditors that have priority over bondholders of a company even though bondholders have priority over stockholders in a company. If you bought a $10,000 bond from a company that goes bankrupt, you have to wait for the bankruptcy process to play out to find out how much, if any, of your original $10,000 investment will be returned to you.

Bond coupon rate

A bond coupon is the interest rate that is paid to the bondholder each year. If a bond has a 5% coupon that means it pays the bondholder 5% in interest each year over the life of that bond. While there are many factors that determine the interest rate of a bond, two of the primary factors are the credit worthiness of the organization issuing the bonds and the bond’s duration.

 The credit worthiness of the bond issuer probably has the greatest weight. If a high-risk company is issuing bonds, investors will most likely demand a high coupon rate compared to a more financial stable company to compensate them for the increased level of risk.  If a 10 year US government bond is being issued for a 3% coupon rate, a high-risk corporate bond may be issued at a coupon rate of 7% or more. Higher risk bonds are sometimes referred to as high yield bonds or junk bonds. On the flipside, organizations with higher credit ratings, normally have the luxury of issuing their bonds at lower interest rates because the market views them as safer.

 The coupon payments, or interest payments, can be made to the bondholder in different durations during the year depending on the terms of the bond. Some bonds issue interest payments quarterly, semi-annually, once a year, and some bonds don’t issue any interest payments until the bonds matures.

 It’s because of this fixed interest-rate structure that high quality bonds are often viewed as a safer investment than stocks because the value of a stock varies every day based on what the value of the company is perceived to be. Whereas bonds just make fixed interest payments and then re-pay you the face value of the bond at a future date. “Face value” is bond lingo for the dollar amount the bond was issued for and the amount that is returned to the bondholder at maturity.

Fixed interest versus variable interest

While most bonds are issued with a fixed interest rate, some bonds have a variable interest rate. If it’s a fixed interest rate, the bond pays the holder a set interest payment over the life of the bond. If it’s a variable interest rate, the interest rate paid to the bond holder can vary throughout the life of the bond. Some of the more common types of bonds that have variable interest rates are floating rate bonds. The interest rate that these bonds pay is typically tied to the variable rate associated with a short term bond benchmark like the LIBOR or the fed funds rate. As the interest of those benchmarks moves up and down, so do the corresponding interest rate paid by the bond.

Duration of a bond

The next big factor that influences the interest rate on a bond is the duration of the bond. “Duration” is bond lingo for the length from time between when the bond is first issued and when the bond matures. Typically, the longer the duration of the bond, the higher the interest rate which makes sense. If a company wants to borrow $10,000 from you for 1 year versus 10 years, as the person lending them the money, you will most likely want a higher interest rate for a 10 year loan versus a 1 year loan because they are holding onto your money for a longer period of time which represents a greater risk to you as the bondholder.   

Interest rate risk

Bonds also have something called interest rate risk. Typically, when interest rates rise, the value of a bond falls, and vice versa if interest rates fall, the value of a bond rises. Up until this point, we have really just talked about coupon payments or interest payments made to a bondholder but the bond itself can change in value over the life of the bond. Let’s say a company is issuing bonds at $1,000 face value each, you buy a bond for $1,000 and at maturity you would expect to receive $1,000 back, but from the time that bond is issued and when it matures, you can normally trade that bond in the open market, and the value of that bond could sell for more or less than your original $1,000 investment.  

 If you buy a bond from a company that is a 10 year bond with a 5% interest rate but then interest rates across the economy begin to fall, and a year from now investors have difficulty finding bonds that are being issued with a 5% interest rate, another investor may pay you more than $1,000 to buy your bond and collect the 5% interest payment for the rest of that bonds life. So instead of just receiving $1,000 for the bond you may receive $1,500. The value paid over and above the bonds face value is considered appreciation which adds to your total return so the total return on a bond investment includes both dividends received and any appreciation if you sell it prior to maturity.

 But that is a two way street, using that same example above, let’s say a company issues you a bond for $1,000 paying a 5% coupon, but now interest rates have moved higher over the next year, and that same company is now issuing bonds at a 7% interest rate, no one wants your 5% bond because they can get a higher interest-rate by buying the new bonds today. If you were to try and sell your bond in the open market you may only receive $900 from another investor because again, they can just pay $1,000 by purchasing the new bonds with the higher interest rate.  

Holding to maturity

If you hold bonds to their maturity,  which means you don’t trade them while you’re waiting for the bond to mature, it eliminates a lot of this interest-rate risk because then it’s just a pure loan. You lent a company $1,000,  they pay you interest over the life of the loan, and then they hand you back your $1,000 at maturity. Interest rates do not impact the face value of a bond in most cases.

 However, when we talk about bond mutual funds, those bond funds can hold hundreds or thousands of bonds, and those mutual funds are priced by “marking to market” each day, meaning they total up all of the value of the bonds in that portfolio as if they were all being sold at 4pm each day.  It’s similar with bond ETFs but they trade intraday. Thus, if you own bonds via mutual funds or ETFs, interest-rate fluctuations will have a greater influence on the total return of your bond investment because there’s no option to just hold it to maturity. Depending on the interest rate environment this could either work for you or against you. The reason why many high-quality bond funds have lost value in 2022 is because interest rates have risen rapidly this year which has caused the value of those bonds to fall.

Duration Matters

There is a correlation between the time to maturity and the impact of interest rates on the price of a bond.   The longer the duration of the bond, the more that can happen to interest rates between the time a bond is issued and the time the bond matures.   For this reason, when interest rates move, it typically has a greater price impact on longer term bonds versus short-term bond.  

Simple example, your own a bond paying 4% that is maturing in 1 year and another bond paying 4% that matures in 20 years, interest rates are moving higher, and the equivalent bonds are now being issued at a 5% coupon rate. Both of your bonds would most likely drop in value but the bond that is maturing in one year will most likely drop by less because they will return your investment sooner, and you can reinvest that money at the new higher rate compared to the 20 year bond that is locked in at the lower interest rate for the next 20 years.

Why would you own a bond mutual fund?

After reading this, I’ll have investors ask, “why would you own a bond mutual fund versus individual bonds if you have this interest rate risk?” For most investors, the answer is diversification. If you have $100,000 to allocate to bonds, purchasing a few different bond funds may be a more efficient and cost-effective way to obtain a diversified bond portfolio compared to purchasing individual bonds. As mentioned earlier, these bond mutual funds may have thousands of bonds within this single investment which have been selected by a professional bond manager that understands all of the intricacies of the fixed income markets. Compare this to an individual investor that now has to go out and select each bond, do their own analysis on a variety of different bond issuer‘s to create diversification of credit, duration, and coupon payments to create their own diversified portfolio.  Also, since we’ve been in historically low interest rate environments, many fixing income investors have been reluctant to lock into a bond ladder which is a popular strategy for individual bond investors.

 Creating a diversified bond portfolio

Similar to stocks, when investing in bonds, it’s important to create a diversified portfolio to help safeguard bondholders against risk. Within a diversified bond portfolio, you may have bonds with varying credit ratings to help achieve a higher level of interest overall with the safer bond issuer‘s offsetting some of the more risky ones that are paying a higher interest rate. You may have bonds that are varying in duration from short-term, intermediate term, all the way to long-term bonds which may also allow a bond investor to achieve higher rates of return over the long term but maintain the necessary amount of liquidity because the short-term bonds are always maturing and are less sensitive to interest rate risks.
