The sensitivity of a bond's price to changes in interest rates is measured by its duration, which is a function of the bond's maturity and coupon rate.
When a bond has a longer maturity, its duration is greater, meaning that its price is more sensitive to interest rate changes. This is because as interest rates rise, the future cash flows from the bond are discounted at a higher rate, resulting in a lower present value of the cash flows and a lower bond price. Similarly, when interest rates fall, the future cash flows are discounted at a lower rate, resulting in a higher present value of the cash flows and a higher bond price.
In addition, when a bond has a lower coupon, it means that the bond's future cash flows are further into the future. This makes the bond more sensitive to interest rate changes because the present value of future cash flows is more affected by changes in interest rates when those cash flows are further into the future.
Therefore, the combination of a longer maturity and a lower coupon results in a greater sensitivity of the bond's price to interest rate changes.
