The one year interest rates in Australia and US are 3% and 1%, respectively. The current spot rate is $0.75/AUD. (Show calculation and steps)
a. What should the one year forward rate be (if IRP holds).
b. If the forward rate is $0.70/AUD is there an arbitrage? If so, how can an arbitrageur incorporate a cashless (i.e. not use any of her current cash) arbitrage? Hint: She will need to borrow in the US or Australia at the current rates. Assume that she will use an amount of 1,000,000 USD or AUD (you must choose the right one…)
Answer:
Interest rate of Australia is 3 %
Interest rate of US is 1 %
Spot rate is $ 0.75 / AUD
1 Year forward rate = Spot rate x (1 + Rate of US) / 1 + rate of Australia)
= $ 0.75 x (1+1 %) / (1 + 3%)
= $ 0.75 x 0.33
= 0.248
givef forward rate = $ 0..70 / AUD
Therefore there is an arbitrage opportunity
Borrowed USD 1,000,000
Interest to to be paid @ 1% 10,000
Total amount will be returned after 1 year 1010,000
Conversion of USD to AUD @ spot rate of 0.75 = 1,333,333.33
Invest in Australia @ 3% = 39, 999.99
Total amount after 1 year = 1,373,333.32
Conversion of USD @ give rate is 0.7 = 96133.32
Amount to be paid = 1010000
Arbitrage - 1106133.32
