Yield Measurement Consider an annual pay 20 year, $1,000 par value, with 6% coupon rate and a full price of $802.07. Calculate the annual pay YTM. Answer : The relation between price and annual pay YTM on this bond is : 802.07 = S20t=1. 60 . + . 1,000 . YTM = 8.019 % (1 + YTM)t (1 + YTM)20 Here we have separated the coupon cash flows and the principal repayment. The calculator solution is : PV = -802.07 FV = 1,000 N = 20 PMT = 60 CPT 1/Y = 8.019, 8.019% is the annual pay YTM.
Yield Measurement A 5 year Treasury strip is priced at $768. Calculate the semiannual pay YTM and annual pay YTM. Answer : The direct calculation method, based on the geometric mean covered in Quantitative method is : semiannual pay YTM or BEY =((1,000)1/10 – 1) x 2 = 5.35% 768 annual pay YTM or BEY =((1,000)1/5 – 1) x 2 = 5.42% 768 Using the TVM calculator function : PV = -768, FV = 1,000, N = 10, PMT = 0, CPT 1/Y = 2.675% x 2=5.35% for the semiannual pay YTM PV = -768, FV = 1,000, N = 5, PMT = 0, CPT 1/Y = 5.42% for the annual pay YTM The annual pay YTM of 5.42% means that $768 earning compound interest of 5.42% / year would grow to $1,000 in 5 years.
Bootstrapping Calculate the value of a 1.5 yr, 8% Treasury bond given the spot :0.5 years = 4% , 1 years = 5% , 1.5 years = 6% N1 N=1; FV=4; PMT=0; I/Y=2% Comp PV =-3.92 N2 N=2; FV=4; PMT=0; I/Y=2.5% Comp PV =-3.81 N3 N=3; FV=104; PMT=0; I/Y=3% Comp PV =-95.17 TOTAL = 3.92 + 3.81 + 95.17 = 102.9
Forward and Spot Rate Investors are willing to accept 4.0% on the 1-year bond today (when they could get 8.167% on the 2-year bond today) only because they expect to receive 12.501% on a 1-year bond 1 year from today. The expected rate is the forward rate. Forward rates can be computed given the Spot rates and vice versa. (1 + Z2)2 = (1+1f0) x (1+1f1) Z2 = [(1.04) (1.12501)]1/2 – 1 = 8.167%
