One of the most popular bond types is corporate bond. Corporations issue corporate bonds in order to raise money. Corporations can issue different bond types with varying characteristics, maturities and terms. Some corporate bonds are callable and with higher interests but they may be more risky than those with lower interest rates. Bond ratings such as those by Moody’s Investors Services will help investors decide between different bond types.

Another type of bonds that are popular among investors is the type issued by the US government. These are called US Treasury bills or T-bills, T-bonds, and T-notes. These three different bond types issued by the government have different maturities. T-bills have the shortest maturity dates whereas T-bonds have the longest. In general, investors like Treasury issues because they are backed by the full faith and credit of the US government.

Agency bonds are also relatively safe. Agency bonds may not be as safe as the US government bonds since they are issued by agencies related to the government. Different bond types issued by agencies may or may not have the full backing of the US government. Some agency bonds are riskier than others. Examples of agency bonds are bonds issued by Fannie Mae and Freddie Mac.

Municipal bonds are also considered safe investments but they also usually do not pay as much interest as corporate bonds. However, municipal bonds or munis for short offer added tax advantages. Their interest payments are usually tax free. Municipal bonds are issued by municipalities such as schools, cities, towns, counties, and states. They can issue different bond types to finance different projects. The terms of different municipal bonds can vary significantly.

While most of the different bond types are classified according to the type of issuer that issue them, there are different bond types that are classified based on their characteristics.

When building your bond portfolio, you need to include many different bond types, of different characteristics, not simply just bonds issued by different types of issuers.
