14. Assume the bid rate of a New Zealand dollar is $.33 while the ask rate is $.335 at Bank X. Assume the bid rate of the New Zealand dollar is $.32 while the ask rate is $.325 at Bank Y.Given this information, what would be your gain if you use $1,000,000 and execute locational arbitrage?

A) $15,385.

B) $15,625.

C) $22,136.

D) $31,250.

16. Assume the following information:

You have $1,000,000 to invest

Current spot rate of pound = $1.30

90-day forward rate of pound = $1.28

3-month deposit rate in U.S. = 3%

3-month deposit rate in Great Britain = 4%

If you use covered interest arbitrage for a 90-day investment, what will be the amount of U.S. dollars you will have after 90 days?

A) $1,024,000.

B) $1,030,000.

C) $1,040,000.

D) $1,034,000.

17. Assume that the U.S. interest rate is 10%, while the British interest rate is 15%. If interest rate parity exists, then:

18. Assume the following information:

U.S. investors have $1,000,000 to invest

1-year deposit rate offered on U.S. dollars = 12%

1-year deposit rate offered on Singapore dollars = 10%

1-year forward rate of Singapore dollars = $.412

Spot rate of Singapore dollar = $.400

Given this information:

A) interest rate parity exists and covered interest arbitrage by U.S. investors results in the same yield as investing domestically.

B) interest rate parity doesn't exist and covered interest arbitrage by U.S. investors results in a yield above what is possible domestically.

C) interest rate parity exists and covered interest arbitrage by U.S. investors results in a yield above what is possible domestically.

D) interest rate parity doesn't exist and covered interest arbitrage by U.S. investors results in a yield below what is possible domestically.

ANSWER: B

SOLUTION: $1,000,000/$.400 = S$2,500,000 x (1.1)

= S$2,750,000 x $.412 = $1,133,000

Yield = ($1,133,000 - $1,000,000)/$1,000,000 = 13.3%

This yield exceeds what is possible domestically.

19. Assume the following information:

Current spot rate of New Zealand dollar = $.41

Forecasted spot rate of New Zealand dollar 1 year from now = $.43

One-year forward rate of the New Zealand dollar = $.42

= NZ$1,317,073 x .42 = $553,171

Yield = ($553,171 - $500,000)/$500,000 = 10.63%
