When you invest in bonds and bond mutual funds, you face the risk that you might lose money, which can happen if the price falls and you sell for less than you paid to buy. Learn about the different types of risks inherent to bond investing.



Like other investments, when you invest in bonds and bond funds, you face investment the risk that you might lose money. In addition, the following risks, which can happen if the price falls and you sell for less than you paid. Just because you take investment risks doesn’t mean you can’t exert some control over what happens to the money you invest.



Remember the cardinal rule of bonds: When interest rates fall, bond prices rise, and when interest rates rise, bond prices fall.

Interest rate risk is the risk that changes in interest rates (in the U.S. or other world markets) may reduce (or increase) the market values of a bond you holds. Interest rate risk—also referred to as market risk—increases the longer you hold a bond.


Let’s look at the risks inherent in rising interest rates.


>> Example: Say you bought a 10-year, $1,000 bond today at a coupon rate of 4 percent, and interest rates rise to 6 percent.


If you need to sell your 4 percent bond prior to maturity you must compete with newer bonds carrying higher coupon rates. These higher coupon rate bonds decrease the appetite for older bonds that pay lower interest. This decreased demand depresses the price of older bonds in the secondary market, which would translate into you receiving a lower price for your bond if you need to sell it. In fact, you may have to sell your bond for less than you paid for it. This is why interest rate risk is also referred to as market risk.


Rising interest rates also make new bonds more attractive (because they earn a higher coupon rate). This results in what’s known as opportunity risk—the risk that a better opportunity will come around that you may be unable to act upon. The longer the term of your bond, the greater the chance that a more attractive investment opportunity will become available, or that any number of other factors may occur that negatively impact your investment. This also is referred to as holding-period risk—the risk that not only a better opportunity might be missed, but that something may happen during the time you hold a bond to negatively affect your investment.


Bond fund managers face the same risks as individual bondholders. When interest rates rise—especially when they go up sharply in a short period of time—the value of the fund’s existing bonds drops, which can put a drag on overall fund performance.




Similar to when a homeowner seeks to refinance a mortgage at a lower rate to save money when loan rates decline, a bond issuer often calls a bond when interest rates drop, allowing the issuer to sell new bonds paying lower interest rates—thus saving the issuer money. For this reason, a bond is often called following interest rate declines. The bond’s principal is repaid early, but the investor is left unable to find a similar bond with as attractive a yield. This is known as call risk.


With a callable bond, you might not receive the bond’s original coupon rate for the entire term of the bond, and it might be difficult or impossible to find an equivalent investment paying rates as high as the original rate. This is known as reinvestment risk.

Additionally, once the call date has been reached, the stream of a callable bond’s interest payments is uncertain, and any appreciation in the market value of the bond may not rise above the call price.




If you own bonds or have money in a bond fund, there is a number you should know. It is called duration. Although stated in years, duration is not simply a measure of time. Instead, duration signals how much the price of your bond investment is likely to fluctuate when there is an up or down movement in interest rates.

The higher the duration number, the more sensitive your bond investment will be to changes in interest rates.


Duration risk is the name economists give to the risk associated with the sensitivity of a bond’s price to a one percent change in interest rates.




A sinking fund provision, which often is a feature included in bonds issued by industrial and utility companies, requires a bond issuer to retire a certain number of bonds periodically. This can be accomplished in a variety of ways, including through purchases in the secondary market or forced purchases directly from bondholders at a predetermined price, referred to as refunding risk.


Holders of bonds subject to sinking funds should understand that they risk having their bonds retired prior to maturity, which raises reinvestment risk.




If you have ever loaned money to someone, chances are you gave some thought to the likelihood of being repaid. Some loans are riskier than others. The same is true when you invest in bonds. You are taking a risk that the issuer’s promise to repay principal and pay interest on the agreed upon dates and terms will be upheld.


While Treasury securities are generally deemed to be free of default risk, most bonds face a possibility of default.

This means that the bond obligor will either be late paying creditors (including you, as a bondholder), or pay a negotiated reduced amount or, in worst-case scenarios, be unable to pay at all.




The Securities and Exchange Commission (SEC) has designated 10 rating agencies as Nationally Recognized Statistical Rating Organizations (NRSROs).

These organizations review information about selected issuers, especially financial information, such as the issuer’s financial statements, and assign a rating to an issuer’s bonds—from AAA (or Aaa) to D (or no rating).

Each NRSRO uses its own ratings definitions and employs its own criteria for rating a given security. It is entirely possible for the same bond to receive a rating that differs, sometimes substantially, from one NRSRO to the next. While it is a good idea to compare a bond’s rating across the various NRSROs, not all bonds are rated by every agency, and some bonds are not rated at all. In such cases, you may find it difficult to assess the overall creditworthiness of the issuer of the bond.




Generally, bonds are lumped into two broad categories—investment grade and non-investment grade.

> Bonds that are rated BBB, bbb, Baa or higher are generally considered investment grade.

> Bonds that are rated BB, bb, Ba or lower are non-investment grade.

Non-investment grade bonds are also referred to as high-yield or junk bonds. Junk bonds typically offer a higher yield than investment-grade bonds, but the higher yield comes with increased risk—specifically, the risk that the bond’s issuer may default. Investors who decide which bonds to buy based solely on a bond’s yield are “reaching for yield,” one of the most common mistakes bond investors make.




Inflation risk is the risk that the yield on a bond will not keep pace with purchasing power (in fact, another name for inflation risk is purchasing power risk).

>>Example: If you buy a five-year bond in which you can realize a coupon rate of 5 percent, but the rate of inflation is 8 percent, the purchasing power of your bond interest has declined. All bonds but those that adjust for inflation, such as TIPS, expose you to some degree of inflation risk.


Liquidity risk is the risk that you will not be easily able to find a buyer for a bond you need to sell. A sign of liquidity, or lack of it, is the general level of trading activity: A bond that is traded frequently in a given trading day is considerably more liquid than one which only shows trading activity a few times a week.


Some bonds, like U.S. Treasury securities, are quite easy to sell because there are many people interested in buying and selling such securities at any given time. These securities are liquid. Others trade much less frequently. Some even turn out to be “no bid” bonds, with no buying interest at all. These securities are illiquid.




Mergers, acquisitions, leveraged buyouts and major corporate restructurings are all events that put corporate bonds at risk, thus the name event risk.


Other events can also trigger changes in a company’s financial health and prospects, which may trigger a change in a bond’s rating. These include a federal investigation of possible wrongdoing, the sudden death of a company’s chief executive officer or other key manager, or a product recall. Energy prices, foreign investor demand and world events also are triggers for event risk. Event risk is extremely hard to anticipate and may have a dramatic and negative impact on bondholders.
