How does interest rates affect bond prices

Bond investors, like all investors, typically try to get the best return possible. To achieve this goal, they generally need to keep tabs on the fluctuating costs of borrowing. An easy way to grasp why bond prices move in the opposite direction of interest rates is to consider zero-coupon bonds , which don't pay regular interest and instead derive all of their value from the difference between the purchase price and the par value paid at maturity.

Zero-coupon bonds are issued at a discount to par value, with their yields a function of the purchase price, the par value, and the time remaining until maturity. This satisfaction, of course, depends on what else is happening in the bond market. Who wants a 5. To attract demand, the price of the pre-existing zero-coupon bond would have to decrease enough to match the same return yielded by prevailing interest rates.

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. You should seek advice from a financial adviser.

Those cash payments are usually made in the form of periodic interest payments and the return of principal when the bond matures. In the absence of credit risk the risk of default , the value of that stream of future cash payments is simply a function of your required return based on your inflation expectations.

If that sounds a little confusing and technical, don't worry, this article will break down bond pricing, define the term " bond yield ," and demonstrate how inflation expectations and interest rates determine the value of a bond.

There are two primary risks that must be assessed when investing in bonds: interest rate risk and credit risk. Though our focus is on how interest rates affect bond pricing otherwise known as interest rate risk , a bond investor must also be aware of credit risk. The U.

Changes in short-term versus long-term interest rates can affect various bonds in different ways, which we'll discuss below. Credit risk, meanwhile, is the risk that the issuer of a bond will not make scheduled interest or principal payments. The probability of a negative credit event or default affects a bond's price — the higher the risk of a negative credit event occurring, the higher the interest rate investors will demand in exchange for assuming that risk.

Bonds issued by the U. Department of the Treasury to fund the operation of the U. Treasury bonds. Depending on the time until maturity, they are called bills, notes or bonds. Investors consider U. Treasury bonds to be free of default risk.

For the remainder of this article, we will use U. Treasury bonds in our examples, thereby eliminating credit risk from the discussion. To understand how interest rates affect a bond's price, you must understand the concept of yield. While there are several different types of yield calculations, for the purposes of this article, we will use the yield to maturity YTM calculation.

A bond's YTM is simply the discount rate that can be used to make the present value of all of a bond's cash flows equal to its price. In other words, a bond's price is the sum of the present value of each cash flow, wherein the present value of each cash flow is calculated using the same discount factor.

This discount factor is the yield.
