1) Calculate the price of the bond from a 10 basis point decrease in yield
2) Using duration, estimate the price of the bond for a 10 basis point decrease in yield
Ans 1. Price of bond when 10 basis points decrease in yield
Annual Interest income from bond = 1000*9% = $90
Maturity is 5 years
Yield after decreasing 10basis points = 8% - .10% = 7.90%
Price of bond = Interest*(Present value annuity of 5 years @7.90%) + Matured value*[email protected]% of 5th year
Price of bond = $90*(4.003255) + $1000*(.683743) = $360.29 + $683.743 = $1044.035 approx.
Ans 2. Price of the bond using duration period
Price = Interest*(Present value annuity of 3.99 [email protected]%) + 1000*[email protected]% of 4th year
Price = 90*(3.319513) + 1000*.737758 = $298.75617 + $737.758 = $1036.514 approx
