The Relation Between Time to Maturity & Bond Price Volatility | Finance - Zacks
market interest rates, bond prices, and yield to maturity of treasury bonds, below, can help you visualize the relationship between market interest rates and . This is because the market price or value of the bond can change over time based. The price or market value of an investment bond is based on the rate of interest the bond pays -- called the coupon rate -- compared to the current market yield. In essence, yield is the rate of return on your bond investment. the same amount of principal returned at maturity, the buyer's yield, or rate of There are many ways to measure yield, but two—current yield and yield to maturity—are of greatest The calculation of yield to call is based on the coupon rate, the length of time.Bonds - Confused between the rates: Spot, Forward, Coupon, Current Yield, IRR, YTM, BEY
As an investor, you need to be aware of the risks involved with different bond choices. One of those risks is the higher volatility of long-term bonds. Bond Price Function The price or market value of an investment bond is based on the rate of interest the bond pays -- called the coupon rate -- compared to the current market yield for similar bonds.
If a bond's coupon rate is higher than market rates, the value of the bond will be higher than the face amount to bring the yield an investor earns in line with current rates. This is called a premium bond.

A discount bond is priced below the face amount, because the bond's coupon rate is lower than current market rates. Bond prices move inversely to interest rate changes. Generally, bonds with long maturities and low coupons have the longest durations.
These bonds are more sensitive to a change in market interest rates and thus are more volatile in a changing rate environment. Conversely, bonds with shorter maturity dates or higher coupons will have shorter durations.
Bonds with shorter durations are less sensitive to changing rates and thus are less volatile in a changing rate environment. Why is this so?
Because bonds with shorter maturities return investors' principal more quickly than long-term bonds do. Therefore, they carry less long-term risk because the principal is returned, and can be reinvested, earlier.
This hypothetical example is an approximation that ignores the impact of convexity; we assume the duration for the 6-month bonds and year bonds in this example to be 0. Duration measures the percentage change in price with respect to a change in yield. FMRCo Of course, duration works both ways.
If interest rates were to fall, the value of a bond with a longer duration would rise more than a bond with a shorter duration. Using a bond's convexity to gauge interest rate risk Keep in mind that while duration may provide a good estimate of the potential price impact of small and sudden changes in interest rates, it may be less effective for assessing the impact of large changes in rates.
This is because the relationship between bond prices and bond yields is not linear but convex—it follows the line "Yield 2" in the diagram below. This differential between the linear duration measure and the actual price change is a measure of convexity—shown in the diagram as the space between the blue line Yield 1 and the red line Yield 2.
The Relationship Between Bonds and Interest Rates
Relationship between price and yield in a hypothetical bond The impact of convexity is also more pronounced in long-duration bonds with small coupons—something known as "positive convexity," meaning it will act to reinforce or magnify the price volatility measure indicated by duration as discussed earlier. Glossary Understanding Yields Yield is a critical concept in bond investing, because it is the tool you use to measure the return of one bond against another.
It enables you to make informed decisions about which bond to buy. In essence, yield is the rate of return on your bond investment.
It changes to reflect the price movements in a bond caused by fluctuating interest rates. Here is an example of how yield works: You buy a bond, hold it for a year while interest rates are rising, and then sell it.
