What is a Bond?

A bond, also known as a fixed-income security, is a debt instrument created for the purpose of raising capital. They are essentially loan agreements between the bond issuer and an investor, in which the bond issuer is obligated to pay a specified amount of money at specified future dates.

There are four major bond types in the U.S. markets, which are represented by four major issuers:


How do Bonds work?

When an investor purchases a bond, they are "loaning" that money (called the principal) to the bond issuer, which is usually raising money for some project. When the bond matures, the issuer repays the principal to the investor. In most cases, the investor will receive regular interest payments from the issuer until the bond matures.

Different types of bonds offer investors different options. For example, there are bonds that can be redeemed prior to their specified maturity date, and bonds that can be exchanged for shares of a company. Other bonds have different levels of risk, which can be determined by its credit rating.

Bond rating agencies like Moody's and Standard & Poor's (S&P) provide a service to investors by grading fixed income securities based on current research. The rating system indicates the likelihood that the issuer will default either on interest or capital payments.

Why do Bonds matter?

Bonds and other fixed-income securities play a critical role in an investor's portfolio. Owning bonds helps to diversify a portfolio, as the bond market doesn't rise or fall alongside the stock market. More important, bonds are generally less volatile then stocks, and are usually viewed as a "safer" investment.
