3. Citibank quotes NZ$1 = US$ 0.6624. Deutsche Bank quotes € 1 = US$1.1758. BNZ Bank quotes € 1 = NZ$1.7762.
a. If these quotes are simultaneously observed spot rates, can you make an arbitrage profit? If so, calculate what profit would you make if you started with N$ 1 million. Assume that there are no transaction costs.
b. What would be your arbitrage profit if you were to incur total transaction costs of 0.1% of the amount used for conversions?
Part A:
Cross rate NZ $ / EUro = [ NZ $ / USD ] * [ USD / Euro ]
Given USD / NZ$ = 0.6624
Indirect Quote = 1 / Direct Quote
= [ 1 / 0.6624 ] * [ 1.1758 ]
= 1.77506
Actual Rate NZ$ / Euro = 1.7762.
As these Rates are not equal, There is Arbitrage gain.
Step 1:
Convert NZ$ into USD = 1000000 * 0.6624
= USD 662400
Step2:
COnvert USD into Euro :
= 662400 / 1.1758
= 563361.12
Step 3:
Convert Euro Into NZ$
= 563361.12 * 1.7762
= 1000642.01
Book Profit = 1000642.01 - 1000000
= NZ$ 642.01
Part B:
Step 1:
Convert NZ$ into USD = 1000000 * 0.6624
= USD 662400
After adjusting Transaction cost = 662400 * (100% - 0.1% )
= 662400* 99.9%
= 661737.60
Step2:
COnvert USD into Euro :
= 661737.60 / 1.1758
= 562797.76
After adjusting Transaction cost = 562797.76 * (100% - 0.1% )
= 562797.76 * 99.9%
= 562234.96
Step 3:
Convert Euro Into NZ$
= 562234.96 * 1.7762
= 998641.73
After adjusting Transaction cost = 998641.73 * (100% - 0.1% )
= 998641.73 * 99.9%
= 997643.09
Book Profit = 997643.09 - 1000000
= - NZ$ 2356.91
If there is transaction cost of 0.1% for each conversion, Arbitrage profit is not possible.
