Now that we have an idea of how a bond's price moves in relation to interest rate changes, it's easy to see why a bond's price would increase if prevailing interest rates were to drop. Given this increase in price, you can see why bondholders, the investors selling their bonds, benefit from a decrease in prevailing interest rates. These examples also show how a bond's coupon rate and, consequently, its market price is directly affected by national interest rates. To have a shot at attracting investors, newly issued bonds tend to have coupon rates that match or exceed the current national interest rate.
This is the rate of interest charged on the inter-bank transfer of funds held by the Federal Reserve Fed and is widely used as a benchmark for interest rates on all kinds of investments and debt securities. Fed policy initiatives have a huge effect on the price of bonds. For example, when the Fed increased interest rates in March by a quarter percentage point, the bond market fell.
The yield on year Treasury bonds T-bonds dropped to 3. The Fed raised interest rates four times in After the last raise of the year announced on Dec. Treasuries , which has resulted in yields plummeting to all-time lows. As of May 24, , the year T-note was yielding 0. Zero-coupon bonds tend to be more volatile , as they do not pay any periodic interest during the life of the bond. Upon maturity, a zero-coupon bondholder receives the face value of the bond.
Thus, the value of these debt securities increases the closer they get to expiring. Zero-coupon bonds have unique tax implications, too, that investors should understand before investing in them. Even though no periodic interest payment is made on a zero-coupon bond, the annual accumulated return is considered to be income , which is taxed as interest. The bond is assumed to gain value as it approaches maturity, and this gain in value is not viewed as capital gains, which would be taxed at the capital gains rate , but rather as income.
In other words, taxes must be paid on these bonds annually, even though the investor does not receive any money until the bond maturity date. This may be burdensome for some investors. However, there are some ways to limit these tax consequences. Federal Reserve. Department of the Treasury. Fixed Income Essentials. Corporate Bonds.

In order to fully understand why that is the value of the bond, you need to understand a little more about how the time value of money is used in bond pricing, which is discussed later in this article. If interest rates were to fall in value, the bond's price would rise because its coupon payment is more attractive. For example, if interest rates fell to 7. The further rates fall, the higher the bond's price will rise, and the same is true in reverse when interest rates rise.
In either scenario, the coupon rate no longer has any meaning for a new investor. However, if the annual coupon payment is divided by the bond's price, the investor can calculate the current yield and get a rough estimate of the bond's true yield.
The current yield and the coupon rate are incomplete calculations for a bond's yield because they do not account for the time value of money, maturity value, or payment frequency.
More complex calculations are needed to see the full picture of a bond's yield. A bond's yield to maturity YTM is equal to the interest rate that makes the present value of all a bond's future cash flows equal to its current price. These cash flows include all the coupon payments and its maturity value. Solving for YTM is a trial and error process that can be done on a financial calculator, but the formula is as follows:.
Bond yields are normally quoted as a bond equivalent yield BEY , which makes an adjustment for the fact that most bonds pay their annual coupon in two semi-annual payments.
However, if the coupon payments were made every six months, the semi-annual YTM would be 5. Investors can find a more precise annual yield once they know the BEY for a bond if they account for the time value of money in the calculation. In the case of a semi-annual coupon payment, the effective annual yield EAY would be calculated as follows:. If an investor knows that the semi-annual YTM was 5. There are a few factors that can make finding a bond's yield more complicated.
For instance, in the previous examples, it was assumed that the bond had exactly five years left to maturity when it was sold, which would rarely be the case. When calculating a bond's yield, the fractional periods can be dealt with simply; the accrued interest is more difficult. For example, imagine a bond that has four years and eight months left to maturity. The exponent in the yield calculations can be turned into a decimal to adjust for the partial year. However, this means that four months in the current coupon period have elapsed and there are two more to go, which requires an adjustment for accrued interest.
A new bond buyer will be paid the full coupon, so the bond's price will be inflated slightly to compensate the seller for the four months in the current coupon period that have elapsed. Bonds can be quoted with a " clean price " that excludes the accrued interest or the " dirty price " that includes the amount owed to reconcile the accrued interest. When bonds are quoted in a system like a Bloomberg or Reuters terminal, the clean price is used.
A bond's yield is the return to an investor from the bond's coupon interest payments. It can be calculated as a simple coupon yield, which ignores the time value of money and any changes in the bond's price or using a more complex method like yield to maturity.
Higher yields mean that bond investors are owed larger interest payments, but may also be a sign of greater risk. The riskier a borrower is, the more yield investors demand to hold their debts.
Higher yields are also associated with longer maturity bonds. Like any investment, it depends on one's individual circumstances, goals, and risk tolerance. Low-yield bonds may be better for investors who want a virtually risk-free asset, or one who is hedging a mixed portfolio by keeping a portion of it in a low-risk asset.
High-yield bonds may instead be better-suited for investors who are willing to accept a degree of risk in return for a higher return. The risk is that the company or government issuing the bond will default on its debts. Diversification can help lower portfolio risk while boosting expected returns. The yield to maturity YTM is the total return anticipated on a bond if the bond is held until it matures.
Yield to maturity is considered a long-term bond yield but is expressed as an annual rate. YTM is usually quoted as a bond equivalent yield BEY , which makes bonds with coupon payment periods less than a year easy to compare.
The annual percentage yield APY is the real rate of return earned on a savings deposit or investment taking into account the effect of compounding interest. The following examples can help you gain a sense of the relationship between prices and yields on bonds. Prevailing interest rates rise during the next 12 months, and one year later, the same company issues a new bond, called Bond B, but this one has a yield of 4.
Nobody would do that, so the original price of Bond A now needs to adjust downward to attract buyers. But how far does its price fall? Over the course of the following year, the yield on Bond A has moved to 4. You won't find the relationship this exact in real life, but this simplified example helps provide an illustration of how the process works. In this example, the opposite scenario occurs. One year later, the company can issue new bond debt at 3.
What happens to the first issue? In this case, the price of Bond A needs to adjust upward as its yield falls in line with the newer issue. The following year, the yield on Bond A has moved to 3. Bonds that already have been issued and that continue to trade in the secondary market must continually readjust their prices and yields to stay in line with current interest rates. A decline in prevailing yields means that an investor can benefit from capital appreciation in addition to the yield.
Conversely, rising rates can lead to loss of principal, hurting the value of bonds and bond funds. Investors can find various ways to protect against rising rates in their bond portfolios, such as hedging their investment by also investing in an inverse bond fund.
A bond's value is based on its time to maturity, coupon payment, and interest rate—in other words, how much the investor will receive for it over a certain period of time.
To calculate the price, you'll need to compare today's rates the discount rate on similar bonds, the present value of remaining payments, and the face value of the bond. Walk through a sample calculation to learn how to do this. Generally speaking, it's wise to invest in more bonds the closer you get to retirement, since bonds are a less risky investment and provide a steadier—but smaller—return than stocks.
It's always good to have bonds in your portfolio to protect against periods of stock market volatility. When interest rates are expected to go up, it's better to avoid investing in long-term bonds, which may see their value erode over time.
