CFA Program Curriculum Lvl II Book 1, Reading 14, Page 495, Example 2 - Calculating the Forward Premium (Discount)
It might just be because it’s very late, but I cannot figure out how the book has come to the answer -0.0254 via the calculations & formulae listed.
Crunching the numbers just does not come out with that answer!!
The spot (CAD/AUD) is 1.0145
270 day LIBOR (AUD) is 4.87%
270 day LIBOR (CAD) is 1.41%
Can anyone shed any light here? I keep coming out with -0.03347, which isn’t even on their answer list!! (Closest is -0.0346, but pretty sure that’s just there as a trick as it’s the difference between the 2 interest rates).
Thanks guys & girls.
