What is a bond?
Much like people, large organizations such as corporations, the federal government, and state and local governments all need to borrow money occasionally. Unlike you and me, it is awfully difficult for these organizations to get as much money as they need just with the promise to repay it the next day. Instead, they have to agree not only to pay back the amount they borrowed, but also to pay a little extra in the form of a fee (interest) for the privilege of borrowing the money.
The first time an ancient monarch borrowed a large sum of money from a rich neighbor, agreed to repay the money with interest, and wrote this up on a piece of papyrus, the bond was born. Deficit-laden governments across the world use bonds as a way to finance their operations. Cash-strapped companies sell debt in order to get the money they need to expand.
Bonds are a form of indebtedness that is sold to the public in set increments, normally in the neighborhood of $1,000. In return for loaning the debtor the money, the lender gets a piece of paper that stipulates how much was lent, the agreed-upon interest rate, how often interest will be paid, and the term of the loan.
If you're interested in investing in bonds, which type should you choose? The pros and cons of individual bonds depend on the lender.
Types of Bonds
Bonds are known as "fixed-income" securities because the amount of income the bond will generate each year is "fixed," or set, when the bond is sold. No matter what happens or who holds the bond, it will generate exactly the same amount of money.
There are four basic kinds of bonds, all defined by who is selling the debt.
- The federal government. U.S. government bonds are called Treasuries because they are sold by the Treasury Department. Treasuries come in a variety of different "maturities," or lengths of time until maturity, ranging from three months to 30 years. Various types of Treasuries include Treasury notes, Treasury bills, Treasury bonds, and inflation-indexed notes. These all vary based on maturity and amount of interest paid. The Treasury Department also sells savings bonds as well as other types of debt through the Bureau of the Public Debt . Treasuries are guaranteed by the U.S. government and are free of state and local taxes on the interest they pay.
- Other government agencies. Some government agencies and quasi-government agencies like the Federal National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage Corp . (Freddie Mac), and the Government National Mortgage Association (Ginnie Mae) sell bonds backed by the full faith and credit of the U.S. for specific purposes, such as funding home ownership.
- Corporate bonds. Companies sell debt through the public securities markets just as they sell stock. A company has a lot of flexibility as to how much debt it can issue and what interest rate it will pay, although it must make the bond attractive enough to interest investors or no one will buy them. Corporate bonds normally carry higher interest rates than government bonds because there is a risk that the company could go bankrupt and default on the bond, unlike the government, which can just print more money if it really needs it. High-yield bonds, also known as junk bonds, are corporate bonds issued by companies whose credit quality is below investment grade. Some corporate bonds are called convertible bonds because they can be converted into stock if certain provisions are met.
- State and local governments (munis). Because state and local governments can go bankrupt (ask the holders of Orange County, California, bonds if you don't believe that one), they have to offer competitive interest rates just like corporate bonds. Unlike corporations, though, the only way that a state can get more income is to raise taxes on its citizens, always an unpopular move. As a way around this problem, the federal government permits state and local governments to sell bonds that are free of federal income tax on the interest paid. State and local governments can also waive state and local income taxes on the bonds, so even though they pay lower rates of interest, for borrowers in high tax brackets the bonds can actually have a higher after-tax yield than other forms of fixed-income investments.
The type of lender will determine many of a bond's features. But there are other characteristics to consider besides the lender.
Characteristics of Bonds
There are three important things to know about any bond before you buy it: the par value, the coupon rate, and the maturity date. Knowing these three items (and a few other odds and ends depending on what kind of bond you are buying) allows you to analyze the bond and compare it to other potential investments.
- Par value is the amount of money the investor will receive once the bond matures, meaning that the entity that sold the bond will return to the investor the original amount that it was loaned, called the principal. As mentioned earlier, par value for corporate bonds is normally $1,000, although for government bonds it can be much higher.
- The coupon rate is the amount of interest that the bondholder will receive expressed as a percentage of the par value. Thus, if a bond has a par value of $1,000 and a coupon rate of 10%, the person holding the bond will receive $100 a year. The bond will also specify when the interest is to be paid, whether monthly, quarterly, semi-annually, or annually.
- The maturity date is the date when the bond issuer has to return the principal to the lender. After the debtor pays back the principal, it is no longer obligated to make interest payments. Sometimes a company will decide to "call" its bond, meaning that it is giving the lenders their money back before the maturity date of the bond. All corporate bonds specify whether they can be called and how soon they can be called. Federal government bonds are never called, although state and local government bonds can be called.
How to Calculate Bond Yields
The key piece of information to know about a bond in order to compare it with other potential investments is the yield. You can calculate the yield on a bond by dividing the amount of interest it will pay over the course of a year by the current price of the bond.
If a bond that cost $1,000 pays $75 a year in interest, then its current yield is $75 divided by $1,000, or 7.5%.
Why bond yields can differ from coupon rates?
Why not just look at the coupon rate to determine the bond's yield? Bond prices fluctuate as interest rates change, so a bond can trade above or below the par value based on what interest rates are. If you hold the bond to maturity, you are guaranteed to get your principal back. However, if you sell the bond before it matures, you will have to sell it at the going rate, which may be above or below par value.
Say you bought a $1,000 bond with a coupon rate of 10% that matures in 10 years. This bond would pay you $100 per year for a decade, at which time you will get back the $1,000 in principal.
Now say you still own that bond seven years later, when long-term interest rates touch 5%. Newly issued bonds, paying that interest rate, would only pay $50 a year, not $100. As a reflection of the fact that interest rates have dropped since the coupon rate was set on the bond, you would actually be able to sell your bond for more than the $1,000 par value. This is because an investor would be willing to pay a premium rate for a bond that paid 10%.
If you hold a bond to maturity, you won't lose your principal as long as the borrower doesn't default or go belly-up. If you buy and sell bonds before they mature, you can make or lose money on the bonds themselves completely separate from the interest rates. How much more you are going to get depends on the exact maturity date of the bond, where interest rates have moved, and the transaction costs involved.
Yield to Maturity
Because you can buy a bond above or below par value, bond investors often use another kind of yield called "yield to maturity." The yield to maturity includes not only the interest payments you will receive all the way to maturity, but it also assumes that you reinvest that interest payment at the same rate as the current yield on the bond and takes into account any difference between the current par value of the bond and the actual trading price of the bond at that time.
If you buy a bond at par value, then the yield to maturity will be very close to the current yield, which is exactly the same as the coupon rate. Yield to maturity is especially important when looking at zero-coupon bonds, a special type of bond that pays no interest until the maturity date, when you receive all of your principal back plus interest for the entire period the money was borrowed. Because zeros have no present yield, any yield you see associated with them is always a yield to maturity.
OK, you've decided that bonds have a place in your portfolio. How do you actually buy a bond?
Buying Bonds
Almost all investors who buy bonds buy them because they are generally safe investments. However, except for bonds from the federal government, bonds carry the potential risk of default, no matter how remote that risk might be. Whether it is a high-yield corporate bond or a bond sold by the sovereign commonwealth of Virginia, there is always a chance that the entity that borrowed the money will not be able to make the interest payment.
Bond ratings were developed as a way to indicate how financially stable the issuer of the bonds really is. Developed by third parties such as Standard and Poor's and Moody's, bond-rating services give bonds letter or mixed letter and number ratings based on the financial soundness of the bond issuer. To complicate things, the rating agencies use entirely different rating systems, making it very important that you check what the ratings mean before you make any assumptions. The higher the rating, the higher the quality of the bond, with Treasury bonds being rated the highest and "junk" bonds being those with the lowest ratings.
Depending on the bond, it can either trade very frequently at a low commission or it may be very difficult to find a buyer or seller and involve large transaction costs. "Liquidity" is the term used to describe how easy it is to sell something. Highly liquid bonds include U.S. Treasuries and debt issued by large, blue-chip corporations. Illiquid bonds would include the bonds of a company viewed as close to bankruptcy. Because it is no longer a safe investment, only those speculating that there will be a corporate turnaround are willing to buy those bonds, meaning they trade a lot less frequently. Liquidity has a direct effect on the commission you pay to trade a bond, which unlike stocks, rarely trade on a fixed commission schedule.
Use a brokerage. The most common way to buy bonds, much like stocks, is to use a brokerage account. You can either use a full-service (or full-price) broker or a discount broker to execute your trades. Bond commissions vary widely from brokerage to brokerage, so it does not hurt to shop around a little before making your decision. Through a brokerage, you can buy anything from a 10-year Treasury to a one-year junk bond issued by a corporation on the edge of bankruptcy. You can either participate in the direct offering of the bonds or pick them up in the secondary market, depending on your brokerage. Telesia can assist you in finding and buying the bond for you.
TreasuryDirect. In an effort to make it easier for citizens to buy U.S. government bonds, the Bureau of the Public Debt started the TreasuryDirect program. This program enables individuals to purchase bonds directly from the Treasury, completely avoiding a brokerage.
Mutual funds. One of the easiest ways to purchase bonds is through a mutual fund. You can invest small amounts (sometimes as little as $25 at a time), sign up for an automatic investment plan (which transfers money from your checking account to your investment account), and achieve instant diversification (since a mutual fund owns thousands of bonds from hundreds of issuers). In fact, for small amounts, bond funds are usually the best bet for investors. However, they do have drawbacks, such as ongoing expenses and a potential loss of principal.
