Risks in International Investing: Foreign ExchangeRisks in International Investing: Foreign Exchange
Exchange rate: The rate at which domestic currency can be converted into foreign currencyExchange Rate Risk
Variation in return related to changes in the relative value of the domestic and foreign currency
Total Return = Investment return plus return on foreign exchange
Not possible to completely hedge a foreign investment

Example 1-Exchange rate riskExample 1-Exchange rate risk
Consider an investment in risk-free government bill paying 10% annual interest in British pounds. Suppose the current exchange rate is $ 2 per pound, and the US investor starts with $20,000.
What happens if the dollar-pound exchange rate varies over the year?

Solution 1-Exchange rate riskSolution 1-Exchange rate risk
The amount can be exchanged for £10,000 and invested at a riskless 10% rate in the UK to provide £11,000 in one year. The depreciation of pound to dollar is 1.80.
10000(10%)=1000 total; £11000
11000(1.80)=£19800
$ 200 relative to $20000
200/20000=0.01 or 1%.

Example 2-Exchange rate riskExample 2-Exchange rate risk
Using the figures in example 1, calculate the rate of return in dollars to a US investor holding the British bill if the year-end exchange rate is;
A) E1=$2.00/£
B) E1=$2.20/£

Solution 2-Exchange rate riskSolution 2-Exchange rate risk
The following formula can be applied:
(1 + rUS) = [1 + rUK]E1 /Eo
A) (1 + rUS) = [1 + 0.1]2 /2
rUS=1.1-1.0=0.1 or 10%
B) (1 + rUS) = [1 + 0.1]2.20 /2
rUS=1.21-1.0=0.21 or 21%

Example 3-Hedging Exchange rate riskExample 3-Hedging Exchange rate risk
Suppose the future exchange rate was $1.93/£ when the investment was made. The US investor could have assured a riskless dollar-denominated return by locking in the year-end exchange rate at $ 1.93/£. Referring to example 1 and
A) Calculate the riskless US return B) Calculate total amount of end-year proceeds in
dollar.

Return in US is a function of two factors
1. Return in the foreign market
2.Return on the foreign exchange

Returns with FXReturns with FX
(1 + rUS) = (1 + rFM) (1 + rFX)
rUS = return on the foreign investment in US Dollars
rFM = return on the foreign market in local currency
rFX = return on the foreign exchange

Constructing benchmark portfolio of Constructing benchmark portfolio of foreign assetsforeign assets
Active or passive international investing requires a benchmark portfolio. One widely used index of non-US stock is European, Australian, Far East (EAFE) index. This index is constructed or computed by Morgan and Stanley.

Currency SelectionCurrency Selection
This measures the contribution to total portfolio performance attributable to exchange rate fluctuations relative to the investor’s benchmark currency, which we will take to be the US dollar. We might use a benchmark like the EAFE index to compare a portfolio’s currency selection for a particular period to a passive benchmark.

Country SelectionCountry Selection
This measures the contribution to performance attributable to investing in better-performing stock markets of the world. It can be measured as weighted average of equity index returns of each country using as weights the share of the manager’s portfolio in each country
