Bonds and Bond Markets

Bond Markets

The volume of capital traded in the bond markets is far greater than what is traded in the stock markets. All sorts of borrowers issue bonds: corporations; national, state and municipal governments; and government agencies. Even small towns issue bonds to finance capital expenditures such as schools, fire stations, and roads. Each kind of bond has its own market.

Private placement refers to bonds that are issued in a private sale rather than through the public markets. The investors in privately placed bonds are institutional investors such as insurance companies, endowments, and pension funds.

U.S. Treasury bonds are issued to the primary market through auctions. Participants, usually dealers or institutional investors, bid for the bonds, but no one participant is allowed to buy enough shares to monopolize the secondary market. Individuals can also buy Treasuries directly from the U.S. Treasury through its online service, called TreasuryDirect (http://www.treasurydirect.gov/).

Corporate bonds are traded in over-the-counter transactions through brokers and dealers. Because the details of each bond issue may vary - maturity, coupon rate, callability, convertibility, covenants, and so on - it is hard to directly compare bond values the way stock values are compared. As a result, the corporate bond markets are less transparent to the individual investor.

To provide guidance, rating agencies provide bond ratings; that is, they "grade" individual bond issues based on the likelihood of default and thus the risk to the investor. Rating agencies are independent agents that base their ratings on the financial stability of the company, its business strategy, competitive environment, outlook for the industry, and the economy - any factors that may affect the company's ability to meet coupon obligations and pay back debt at maturity.

Ratings agencies such as Fitch Ratings, A. M. Best, Moody's, and Standard & Poor's (S&P) are hired by large borrowers to analyze the company and rate its debt. Moody's also rates government debt. Ratings agencies use an alphabetical system to grade bonds (shown in Figure 16.3 "Bond Ratings") based on the highest-to-lowest rankings of two well-known agencies.

A plus sign (+) following a rating indicates that it is likely to be upgraded, while a minus sign (−) following a rating indicates that it is likely to be downgraded.

Bonds rated BBB or Baa and above are considered investment grade bonds, relatively low risk and "safe" for both individual and institutional investors. Bonds rated below BBB or Baa are speculative in that they carry some default risk. These are called speculative grade bonds, junk bonds, or high-yield bonds. Because they are riskier, speculative grade bonds need to offer investors a higher return or yield in order to be "priced to sell".

Although the term "junk bonds" sounds derogatory, not all speculative grade bonds are "worthless" or are issued by "bad" companies. Bonds may receive a speculative rating if their issuers are young companies, in a highly competitive market, or capital intensive, requiring lots of operating capital. Any of those features would make it harder for a company to meet its bond obligations and thus may consign its bonds to a speculative rating. In the 1980s, for example, companies such as CNN and MCI Communications Corporation issued high-yield bonds, which became lucrative investments as the companies grew into successful corporations.

Default risk is the risk that a company won't have enough cash to meet its interest payments and principal payment at maturity. That risk depends, in turn, on the company's ability to generate cash, profit, and grow to remain competitive. Bond-rating agencies analyze an issuer's default risk by studying its economic, industry, and firm-specific environments and estimate its current and future ability to satisfy its debts. The default risk analysis is similar to equity analysis, but bondholders are more concerned with cash flows - cash to pay back the bondholders - and profits rather than profits alone.

Bond ratings can determine the coupon rate the issuer must offer investors to compensate them for default risk. The higher the risk, the higher the coupon must be. Ratings agencies have been criticized recently for not being objective enough in their ratings of the corporations that hire them. Nevertheless, over the years bond ratings have proven to be a reliable guide for bond investors.
