A 5-year bond with face value $1,000 (paid at maturity) and
coupon rate 5%
(coupon paid in arrears annually) has yield-to-maturity 4.5%. What
is the
convexity of the bond?
Calculation of convexity of the bond:
Excel Formulas:
Therefore,
convexity = [1 / (P x (1+Y)2)] x Σ [(cash flows in the tth period / (1 + Y)t ) x (t+t2)]
= 1 / [1021.9499 x (1+4.5%)2] x 27011.96
= 27011.96 / [1021.9499 x (1.045)2]
= 27011.96 / (1021.9499 x 1.092025)
= 27011.96 / 1115.99484
= 24.204
convexity of the bond is 24.204
