Answer:
1.2904
Step-by-step explanation:
S + P = C + X/(1+r)^n
S = ?, P = Premium of put 0.02, C = Premium of call 0.06, X = Strike price (1.25), r = 4%, n = 1.25 (3/12)
S + 0.02 = 0.06 + 1.25/(1.04)^0.25
S = 0.06 + 1.2378 - 0.02
S = 1.2778
F = S(1+r)^n
F = 1.2778*(1.04)^(3/12)
F = 1.2778*1.009853
F = 1.2903901634
F = 1.2904
So, the 3 month ahead forward rate that is consistent with put call parity is 1.2904.
