Question 13

Suppose you observe the following 1-year interest rates, spot exchange rates and futures prices. Futures contracts are available on €10,000. How much risk-free arbitrage profit could you make on 1 contract at maturity from this mispricing?

B)$153.10
C)$439.42
D)None of the above The futures price of $1.48/€ is above the IRP futures price of $1.4641/€, so we want to sell . To hedge, we borrow $14,077.67 today at 4%, convert to euro at the spot rate of $1.45/€, invest at 3%. At maturity, our investment matures and pays €10,000, which we sell for $14,800, and then we repay our dollar borrowing with $14,640.78. Our risk-free profit = $159.22 = $14,800 - $14,640.78.

C)$3,294.12
D)$4,218.75

Question 75

Verify that the dollar value of your put option equals the dollar value of your call.
Your answer is worth zero points if it does not include currency symbols ($,€)!

Question 77

Find the value of a one-year call option on €10,000 with a strike price of $15,000. In one year the exchange rate (currently S₀($/€) = $1.50/€) can increase by 60% or decrease by 37.5% . The current one-year interest rate in the U.S. is i_$ = 4% and the current one-year interest rate in the euro zone is i_€ = 4%.

A)€1,525.52
B)$3,328.40
C)$4,992.60
D)€2,218.94
E)None of the above

Question 78

Question 79

Value a 1-year call option written on £10,000 with an exercise price of $2.00 = £1.00. The spot exchange rate is $2.00 = £1.00; The U.S. risk-free rate is 5% and the U.K. risk-free rate is also 5%. In the next year, the pound will either double in dollar terms or fall by half (i.e. u = 2 and d = ½). Hint: H = ⅔.

A)$6,349.21
B)
C)
D)None of the above

Question 80

The same call from the last question (a 1-period call option on €10,000 with a strike price of $12,500. could also be thought of as a 1-period at-the-money put option on $12,500 with a strike price of €10,000.
As before, the spot exchange rate is €1.00 = $1.25. In the next period, the euro can increase in dollar value to $2.00 or fall to $1.00. The interest rate in dollars is i_$ = 27.50%; the interest rate in euro is i_€ = 2%.
