Problem 4 (30 Points) The current Japanese yen/US dollar spot rate is 80 per dollar (that is, Ey/s = 80), and the current 3-month forward rate is 75 per dollar (that is, Fy/s = 75). 1. Is there a 3-month forward premium or discount on dollars? Compute the 3-month rate of the forward premium or discount. (5 pts) 2. Is there a 3-month forward premium or discount on yens? Compute the 3-month rate of the forward premium or discount. (5 pts) 3. If you forecast that the spot rate will be 72 per dollar in 3 months, what is the risk premium (or discount) on dollars? If you acted as a speculator, what currency transactions would need to be done so that you might earn a reward for taking such a speculative risk. Assume that you have the initial fund of $100. (10 pts) 4. Starting from your initial fund of $100, what will be your rate of return on your risk-taking transactions if the spot rate in 3 months turn out to be Y75 per dollar rather than your forecast of Y72? (5 pts) 5. Again, starting from your initial fund of $100, what will be your rate of return on your risk- taking transactions if the spot rate in 3 months turn out to be Y82 per dollar rather than your forecast of 72? (5 pts) This was all the information given to me
