Answer:
7.65%
Explanation:
It use asked to find the 2 year forward rate 4 years from now. In this regards, the formula should be:
(1 + %6year)^6 = (1 + %4year)^4 * (1 + %Fwd2year)^2
We have values for 6 and 4 year and we only need the Fwd2 year rate
(1 + 0.0715)^6 / ( 1 + 0.069) ^4 = ( 1 + Fwd2year) ^ 2
Fwd2year = 7.65%
