compounded) yield of 5%? paying 470 p.a. 4 Swaps 1. The 22 July Overnight Interest Swap rates are: Maturity Rate Compounding frequency 1 week 0.37126% Weekly 1 month 0.25034% Monthly 3 months 0.22830% Quarterly 6 months 0.22249% Semi-annually 1 year 0.22000% Annually 2 years 0.22000% Quarterly 0.26000% Quarterly 5 years 0.37000% Quarterly 0.72000% Quarterly 3 years 10 years The contracts out to one year only make a single payment. 2 year and longer maturities make quarterly payments. (a) For the 3 month, 6 month, and 1 year contracts, convert the rate into continuous com- pounding. These are the zero rates for these maturities. (b) If you interpolate the 9 month zero rate as being the average of the 6 and 12 month zero rates, what is the 9 month rate (with continuous compounding)? (c) What are the discount factors for 3 months, 6 months, 9 months and 12 months? (d) Now suppose that the 15 month. 18 month, and 21 month swap rates are also 0.22000% Swap rates are par yields, so this means that you can think of these as coupon rates om bonds that have price 100. Bootstrap the 15 month, 18 month. 21 month, and 24 mont discount factors. The more kosher way to tackle this problem would be to suppose that the 15, 18. and 21 month rates are follows: r(1.25) 0.75r(1) +0.25r(2) (1.5) = 0.5r(1) +0.5r(2) r(1.75) 0.25r(1) +0.75r(2) The two year zero rate should satisfy: 100 0.055e - (0.25) 0.25 -0.055 - (0.5)0.5 +0.055e - (0.75)X0.75 +0.055e- (1)x1 +0.055 - (1.25)x1.25 +0.055e - (1.5)x1.5 +0.055e - (1.75)X1.75 + 100.055e - (2)X2.0 You'd then use excel to solve for the level r(2) that satisfies this equation. This is the two year zero rate. If you wa to try this, you may find Goalseek in excel helpful. It will vary the contents of one cell to set the value of another cu equal to a particular value. 2
