Suppose the Japanese yen exchange rate is ¥75 = $1, and the British pound exchange rate is £1 = $1.54.
a. What is the cross-rate in terms of yen per pound? (Round your answer to 2 decimal places, e.g., 32.16.)
Cross-rate ¥/£
b. Suppose the cross-rate is ¥120 = £1. What is the arbitrage profit per dollar used? (Do not round intermediate calculations and round your answer to 4 decimal places, e.g., 32.1616.)
Arbitrage profit $
a) | $1 = yen 75 | |||||||
1 pound = $ 1.54 | ||||||||
yen per pound | ||||||||
Cross rate = 75*1.54 | ||||||||
115.5 | ||||||||
1 pound = Yen 115.50 | ||||||||
b) | If the cross rate is 1 pound = Yen 120 | |||||||
than the arbitrage profit would be | ||||||||
The yen is quoted high relative to the pound. So,take out a loan for $1 and buy £0.6494(1/1.54) | ||||||||
Use the pounds to purchase yen at the cross-rate, which will give you: £0.6494(¥120/£1) = ¥77.928 | ||||||||
Use the pounds to buy back dollars and repay the loan. | ||||||||
The cost to repay the loan will be: ¥77.928($1/¥75) = $1.03904 | ||||||||
The arbitrage profit is $0.03904 per dollar used. |
