Securities Markets

When many people think of financial markets, they picture the equity markets. However, the bond markets are huge – the Securities Industry and Financial Markets Association (SIFMA) estimates that the global bond market is nearly $88 trillion. In the United States, companies and government entities sold about $2 billion in new bond issues in 2016. Average daily trading volume exceeded $760 billion, with U.S. Treasury securities accounting for more than 60 percent of the total.

Bonds can be bought and sold in the securities markets. However, the price of a bond changes over its life as market interest rates fluctuate. When the market interest rate drops below the fixed interest rate on a bond, it becomes more valuable, and the price rises. If interest rates rise, the bond's price will fall. Corporate bonds, as the name implies, are issued by corporations. They usually have a par value of $1,000. They may be secured or unsecured (called debentures), include special provisions for early retirement, or be convertible to common stock. Corporations can also issue mortgage bonds, bonds secured by property such as land, buildings, or equipment. Approximately $1.5 trillion in new corporate bonds were issued in 2016.

In addition to regular corporate debt issues, investors can buy high-yield, or junk, bonds – high-risk, high-return bonds often used by companies whose credit characteristics would not otherwise allow them access to the debt markets. They generally earn 3 percent or more above the returns on high-quality corporate bonds. Corporate bonds may also be issued with an option for the bondholder to convert them into common stock. These convertible bonds generally allow the bondholder to exchange each bond for a specified number of shares of common stock.

Elon Musk and his electric car company, Tesla, issued high-yield junk bonds in August 2017 and raised nearly $1.8 billion to help finance the production and launch of Tesla's new Model 3. Tesla has spent billions of dollars in its efforts to develop electric cars in the past few years. What are the risks and rewards of buying junk bonds?

U.S. Government Securities and Municipal Bonds

Both the federal government and local government agencies also issue bonds. The U.S. Treasury sells three major types of federal debt securities: Treasury bills, Treasury notes, and Treasury bonds. All three are viewed as default-risk-free because they are backed by the U.S. government. Treasury bills mature in less than a year and are issued with a minimum par value of $1,000. Treasury notes have maturities of 10 years or less, and Treasury bonds have maturities as long as 25 years or more. Both notes and bonds are sold in denominations of $1,000 and $5,000. The interest earned on government securities is subject to federal income tax but is free from state and local income taxes. According to SIFMA, a total of $1.7 trillion U.S. treasuries were issued in 2016, down 20 percent from 2015.

Municipal bonds are issued by states, cities, counties, and other state and local government agencies. Almost $445.8 billion in municipal bonds were issued in 2016.

These bonds typically have a par value of $5,000 and are either general obligation or revenue bonds. General obligation bonds are backed by the full faith and credit (and taxing power) of the issuing government. Revenue bonds, on the other hand, are repaid only from income generated by the specific project being financed. Examples of revenue bond projects include toll highways and bridges, power plants, and parking structures. Because the issuer of revenue bonds has no legal obligation to back the bonds if the project's revenues are inadequate, they are considered more risky and therefore have higher interest rates than general obligation bonds.

Municipal bonds are attractive to investors because interest earned on them is exempt from federal income tax. For the same reason, the coupon interest rate for a municipal bond is lower than for a similar-quality corporate bond. In addition, interest earned on municipal bonds issued by governments within the taxpayer's home state is exempt from state income tax as well. In contrast, all interest earned on corporate bonds is fully taxable.
