HW#3

Chapt 4 (Continuous Compounding) # 1,4,9
Chapt 4 (Interest Rate Markets - FRA) # 5,6,23

Some check answers:
Chapt 4
1.   Rc = 13.76%
4.   with monthly compouding is 9.57%
9.   Rc = 14.91%

5a.  f1,2 = 8.4%   5b. f2,3 8.8%
6. $893.56
12.  YTM is 6.407% c.c.
23.  
Value FRA = L(Rk - Rf)*(T2 - T1)*exp(-R2T2)      (recall payment structured as if in arrears!
                      = $1,000,000 * (0.06 - 0.0575)*0.5 * exp(-0.0494*2)  



5.  Here is a more detailed answer to #5:
Maturity (months) Spot Rate cc Forward Rate
3 8.0
6 8.2 8.4 exp(0.082*6/12) = exp(0.08*3/12)*exp(f1,2*3/12)
9 8.4 8.8
12 8.5 8.8
15 8.6 9.0
18 8.7 9.2

6.  From 12-15 months, forward rate is 9.0% c.c. or 9.102% quarterly, using  
Rm = m*(exp(Rc/m) - 1)  = 4*[exp(.09/4)-1) = 9.102%
    Value FRA = L(Rk - Rf)*(T2 - T1)*exp(-R2T2)      (recall payment structured as if in arrears!
                      = $1,000,000 * (0.095 - 0.09102)*0.25 * exp(-0.086*15/12)  
                       = 893.56
