There are at least five different types of bonds. They each have different sellers, purposes, buyers and levels of risk versus return.  

  1. The most important are the U.S. Treasury bills, notes and bonds issued by the Treasury Department. They are used to set the rates for all other long-term, fixed-rate bonds. The Treasury sells them at auction to fund the operations of the federal government. They are also resold on the secondary market. They are the safest since they are guaranteed by the world's largest economy. That means they also offer the lowest return. However, they are owned by almost every institutional investor, corporation and sovereign wealth fund. The Treasury also sells Treasury Inflation Protected Securities that protect against inflation.
  1. Savings bonds are also issued by the Treasury Department. These are meant to be purchased by individual investors. That's why they are issued in low enough amounts to make them affordable for individuals. I bonds are like Savings bonds, except they are adjusted for inflation every six months.
  2. Quasi-governmental agencies, like Fannie MaeFreddie Mac or Ginnie Mae, sell bonds that are guaranteed by the federal government.
  3. Municipal bonds are issued by various cities. These are tax free but have slightly lower interest rates than corporate bonds. They are slightly more risky than bonds issued by the federal government. Cities occasionally do default.
  4. Corporate bonds are issued by all different types of companies. They are riskier than government-backed bonds so they offer a higher rate of return. They are sold by the representative bank. There are three types of corporate bonds: 
    • Junk bonds or high yield bonds are corporate bonds from companies that have a big chance of defaulting. They offer higher interest rates to compensate for the risk.
    • Preferred stocks are technically stocks but act like a bonds. Like bond payments, they pay you fixed dividend at regular intervals. They are slightly safer than stocks because holders get paid after bondholders but before common stockholders.
    • Certificates of Deposit are like bonds issued by your bank. You essentially loan the bank your money for a certain period of time for a guaranteed fixed rate of return.

    Types of Bond-based Securities

    You don't have to buy an actual bond to take advantage of its benefits. You can also buy securities that are based on bonds. They include bond mutual funds. These are collections of different types of bonds. Here's the difference between bonds and bond funds.

    Bond securities also include bond exchange-traded funds.

    They perform like mutual funds but they don't actually own the underlying bonds. Instead, ETFs track the performance of different classes of bonds. They pay out based on that performance. 

    Bond-based derivatives are complicated investments that get their value from the underlying bonds. They include:

    • Options give a buyer the right, but not the obligation, to trade a bond at a certain price on an agreed-upon future date. The right to buy a bond is called a call option and the right to sell it is called the put option. They are traded on a regulated exchange.
    • Futures contracts are like options except they obligate participants to execute the trade. They are traded on an exchange.
    • Forward contracts are like futures contracts, except they are not traded on an exchange. Instead, they are traded over-the-counter either directly between the two parties or through a bank. They are customized to the particular needs of the two parties. For example, mortgages to-be-announced are forward contracts for mortgage-backed securities sold at a future date.
    • Mortgage-backed securities are based on bundles of home loans. Like a bond, they offer a rate of return based on the value of the underlying assets.
    • Collateralized debt obligations are based on auto loans and credit card debt. These also include bundles of corporate bonds.
    • Asset-backed commercial paper are one-year corporate bond packages based on the value of underlying commercial assets such as real estate, corporate fleets or other business property.
    • Interest rate swaps are contracts that allow bondholders to swap their future interest rate payments. They occur between a holder of a fixed-interest bond and one holding a flexible-interest bond. They are traded over-the-counter.
    • Total return swaps are like interest rate swaps except the payments are based on bonds, a bond index, an equity index or a bundle of loans. (Source: “Introduction to Fixed Income Derivatives,” Ennis Knupp and Associates.  “Overview of Derivatives, “ Chicago Board Options Exchange.)
