What is a Junk Bond?

Brendan McGuigan

A junk bond is typically a high-interest loan with relatively unfavorable terms to compensate for a high risk of default. Junk bonds are a type of high-yield debt, and by far the most common.

By hiding much of their debt off-book, Enron received higher ratings than they would otherwise have earned.

Bonds are rated according to the credit rating of the borrower. In the US, the major rating agencies are Fitch, Standard and Poor's, and Moody's. The rating scheme in descending order of value is: AAA, AA, A, BBB, BB, B, CCC, CC, C, D. Anything rated BB or below is generally considered to be a junk bond because the credit risk is so great.

In the modern economy, bonds are traded like any commodity. Investment companies try to maximize their profit by balancing the safety of an investment with the cost of the bond on the market. Junk bonds are very attractive to some investment groups because of their low cost.

In some cases, an investor may be prohibited by the bylaws of the group they belong to, such as a company pension fund, from purchasing any bonds rated below A or BB. This limitation makes the junk bond market considerably more limited than the market for high-graded bonds, commonly referred to as investment-grade bonds.

The use of the junk bond is widespread throughout sectors that require significant amounts of capital to operate. The telecommunications and energy sectors are two industries which utilize the junk bond extensively. Recently it has come to light that a number of companies have manipulated the appearance of their debt to help them receive a higher rating on their bonds so they could more easily trade them on the market.

Enron is probably the best known example of a company distorting apparent debt to make their portfolio not consist primarily of junk bonds. By hiding much of their debt off-book, Enron received higher ratings than they would otherwise have earned. WorldCom, similarly, was initially not rated as a junk bond company because of illicit accounting practices.

The junk bond also plays an important role in the leveraged buyout and hostile takeover, allowing groups of investment bankers to raise large amounts of capital to use in acquiring a target corporation, paying off the junk bond interest with the newly acquired corporation's cash flow.

@Valencia - I see where you are coming from but I wouldn't be too suspicious. The penalties for this kind of behavior are quite serious, and I'm sure most high yield bond offers are genuine.

Overall there are as many benefits as there are worries. If you are nervous of them then try adding just a few to your portfolio and see what happens. My financial advisor convinced me to try this because they can actually be more stable against interest rates than regular stocks and bonds!


I can see that junk bonds aren't marketed as a particularly safe investment, but how can you trust them at all? With major companies manipulating their debts to fool investors, how can I be sure that there are not many more doing the same thing?


A few years ago I made the decision to divert 10% of my annual bond profits into a junk bond fund. This appeals to my reckless side but is slightly less risky than individual purchases would be.

I'm generally happy with my strategy, and so long as junk bond yields stay around 5% above the standard I won't be panicking.

You do need to be prepared to forget about the money for a while though, as many have strict rules re early cash outs.
