Suppose that the one-year interest rate is 4.58 percent in the United States and 2.66 percent in Germany, and that the spot exchange rate is $1.1321/€ and the one-year forward exchange rate, is $1.2449/€. Assume that an arbitrageur can borrow up to $1,000,000. Calculate his arbitrage profit. If there is no arbitrage opportunities enter zero as your answer.
Particulars | Amount |
Spot Rate | $ 1.1321 |
Hi | 4.5800% |
Fi | 2.6600% |
Home Country | US |
Foreign Country | Germany |
Forward rate after ( in Years) | 1 |
Actual Fwd Rate | $ 1.2449 |
Fwd rate after ( In Months) | 12 |
Amount Borrowed | $ 1,000,000.00 |
According to Int Rate parity Theorm,
Fwd rate After 1 Years = Spot rate * [ ( 1 + Hi ) ^ n ] / [ ( 1 +
Fi ) ^ n ]
= $ 1.1321 * [ ( 1 + 0.0458) ^ 1 ] / [ ( 1 + 0.0266 ) ^ 1 ]
= $ 1.1321 * [ ( 1.0458) ^ 1 ] / [ ( 1.0266 ) ^ 1 ]
= $ 1.1321 * [ 1.0458 ] / [ 1.0266 ]
= $ 1.1321 * [ 1.0187 ]
= $ 1.1533
As Actual Fwd rate is not equal to IRPT Fwd rate, Covered Interest arbitrage exists.
Foreign Currency Premium or Discount:
= [ [ Fwd rate - Spot Rate ] / Spot Rate ] * 100
= [ [ $ 1.2449 - $ 1.1321 ] / $ 1.1321 ] * 100
= [ [ $ 0.1128 / $ 1.1321 ] * 100
= [ 0.0996 ] * 100
= 9.9638 %
Annualized % = Premium or Discounted / No. of Years
= 9.9638 % / 1
= 9.96 %
Effective Rate in Home Country
Effective Rate in Foreign Country
Effective Rate in Foreign currency = Int rate + Fwd Premium
%
= 2.66 % + 9.96 %
= 12.62 %
Strategy:
Step | Activity | |
1 | Borrow in Home Country | |
2 | Convert Into Foreign currency using spot rate | |
3 | Invest in foreign currency for specified period | |
4 | Realize the Maturity Value in Foreign Currency | |
5 | Convert foreign currency proceedings into Home Currency using Actual Fwd Rate | |
6 | Maturity of Loan in Home country | |
7 | Repay the loan along with Int and book profit |
Step 1:
Amount Borrowed $1,000,000.00
Step 2:
Amount in Foreign Currency 883,314.19
Step 3:
Invest in foreign currency for specified period 1
Years
Step 4:
Realize the Maturity Value in Foreign Currency
Maturity Value = Amount Deposited * ( 1 +r ) ^ n
r = Int Rate per anum
n - Time period in Years
= 883314.19 * ( 1 + 0.0266 ) ^ 1
= 883314.19 * ( 1.0266 ) ^ 1
= 883314.19 * ( 1.0266 )
= 906810.35
Step 5:
Convert foreign currency proceedings into Home Currency using
Actual Fwd Rate
= 906810.35 * 1.2449
= 1128888.20
Step 6:
Maturity of Loan in Home country
= 1000000 * ( 1 + 0.0458 ) ^ 1
= 1000000 * ( 1.0458 ) ^ 1
= 1000000 * ( 1.0458 )
= 1045800
Step 7
Profit = Amount realized from Inv - maturity Value of
Loan
= 1128888.20 - 1045800
= 83088.20
Book Profit of 83088.20 after 1 year.
