The term structure is flat at 6%. A bond has 10 years to maturity and coupon rate 8%. Coupon payments are semiannual, par values are 100, and interest rates are expressed as semiannual APRs. (a) Compute the bonds convexity. (b) Suppose the term structure moves up to 7% (still staying flat). What is the bonds new price? (c) Compute the approximate price change using duration, and compare it to the actual price change. (d) Compute the approximate price change using duration and convexity. Comment on the accuracy of the approximation.
