Before you add bonds to your portfolio, you should understand how they work and what variations exist among them. Just as importantly, you need to identify the risks that come with owning bonds and how you can protect yourself from them.
Bond Basics
Bonds are essentially IOUs, issued by federal, state, and municipal governments as well as by corporations and governmental agencies. They are intended to raise revenue for a wide variety of activities. For example, governments issue bonds to finance the construction of infrastructure projects, such as roads, bridges, airports, public housing, and schools. Corporations may use the proceeds of bonds to pay for the construction of new manufacturing facilities, research and development, or to expand into new markets.
Bond investors essentially loan money to the bond’s issuer. In return, they receive interest payments at specified intervals plus a promise that the issuer will return the bond principal to investors when the bond’s term ends on its maturity date.1
Interest Rate Risk
Bonds are not a risk-free investment. Rising interest rates may reduce the desirability of the bonds you own because there is an inverse relationship between bond prices and yield. If you opt to sell a bond before it matures because interest rates on newly issued bonds have gone up, you will most likely have to accept a lower price than you paid for it.
The Importance of Credit Quality
Credit risk — or the risk that a bond issuer will fail to make promised interest and principal payments — is another important consideration. Bonds issued by companies or entities that are financially healthy are not as risky as bonds from issuers that are less financially sound. Bonds with low credit ratings offer higher yields to compensate for added risk to your portfolio.
Rating Agencies
Rating services assess municipal bonds, all types of corporate bonds, and international bonds. U.S. Treasury bonds are not rated. Before rating a bond, analysts assess various factors that could affect the issuer’s willingness and ability to meet its obligations to bondholders. For example, they examine other debt the company carries and how fast the company’s revenues and profits are growing. They take a holistic approach in that they also review the state of the economy and the financial health of other companies in the same business. In the case of municipal bond issuers, they examine and compare municipalities of a similar size and similar budget.
Credit ratings influence the interest rate an issuer must pay in order to sell its bonds. However, credit ratings are opinions about credit risk. Even though credit ratings are forward looking in that they assess the impact of foreseeable future events and can be useful to investors, they are not a guarantee that an investment will pay out or that an issuer will not default. While investors may use credit ratings in making investment decisions, they are not indicators of investment worth nor are they buy, sell, or hold recommendations. You can learn more about the rating systems of the two major services, Standard & Poor’s and Moody’s, on their websites.
