2 Exchange Rates Exchange rate is the price of one currency in terms of another. Exchange rate is the price of one currency in terms of another. On October 18, 2002 at 15:48:14 GMT, 1USD was worth € or 1€ was worth $ On October 18, 2002 at 15:48:14 GMT, 1USD was worth € or 1€ was worth $ On Jan. 1, 1999, 1€=$1.1497; on March 5, 2001, 1€=$ On Jan. 1, 1999, 1€=$1.1497; on March 5, 2001, 1€=$ You can check the exchange rates at You can check the exchange rates at

3 Exchange Rates Changes in the exchange rates affect the prices of imports, exports, foreign assets purchased by locals and local assets purchased by foreigners. Changes in the exchange rates affect the prices of imports, exports, foreign assets purchased by locals and local assets purchased by foreigners. When the domestic currency becomes more valuable (appreciates, becomes stronger), foreign commodities and assets become cheaper. When the domestic currency becomes more valuable (appreciates, becomes stronger), foreign commodities and assets become cheaper.

4 Exchange Rates If €1=$ on 01/01/99 and €1=$ on 03/05/01, then euro depreciated and USD appreciated in this period. If €1=$ on 01/01/99 and €1=$ on 03/05/01, then euro depreciated and USD appreciated in this period. European goods and assets would be cheaper at the recent date. European goods and assets would be cheaper at the recent date. American goods and assets would be more expensive at the recent date. American goods and assets would be more expensive at the recent date. In this example exchange rates are given per euro. In this example exchange rates are given per euro.

5 Price Comparisons Suppose on 1/01/99 and 3/5/01 the price of a Ferrari remained €100,000. Suppose on 1/01/99 and 3/5/01 the price of a Ferrari remained €100,000. Likewise, the price of a server at those dates was $50,000. Likewise, the price of a server at those dates was $50,000. A Ferrari would have cost Americans $114,970 on 1/01/99 and $93,580 on 3/5/01. A Ferrari would have cost Americans $114,970 on 1/01/99 and $93,580 on 3/5/01. A server would have cost Europeans [($50,000)(€1/$1.1497)]=€43, on 1/01/99 and on 3/5/01 [($50,000)(€1/$0.9358)]=€53, A server would have cost Europeans [($50,000)(€1/$1.1497)]=€43, on 1/01/99 and on 3/5/01 [($50,000)(€1/$0.9358)]=€53,

6 Price Comparisons If the currency appreciates (as in the previous example for USD) imports become cheaper and exports more expensive. If the currency appreciates (as in the previous example for USD) imports become cheaper and exports more expensive. US can get more European goods for the same amount of exports: terms of trade improvement. US can get more European goods for the same amount of exports: terms of trade improvement. If the currency depreciates (€ in the example), Europe has to give up more exports for the same amount of imports: terms of trade deterioration. If the currency depreciates (€ in the example), Europe has to give up more exports for the same amount of imports: terms of trade deterioration.

An importer has to instruct her bank to pay the exporter in exporter’s currency. An importer has to instruct her bank to pay the exporter in exporter’s currency. The bank has to exchange the domestic currency for foreign currency and transfer the funds to the exporter’s bank. The bank has to exchange the domestic currency for foreign currency and transfer the funds to the exporter’s bank. Because they are involved with FX market, banks also buy and sell for their own accounts to reduce risk. Because they are involved with FX market, banks also buy and sell for their own accounts to reduce risk.

More and more nonbank financial institutions have been undertaking banking functions. More and more mutual funds, insurance companies have been involved in foreign businesses. More and more mutual funds, insurance companies have been involved in foreign businesses.

12 Central Banks Central banks keep international reserves to intervene in the FX market to keep the exchange rate at a target level. Central banks keep international reserves to intervene in the FX market to keep the exchange rate at a target level.

13 The Location of FX Market FX is traded 24/7 around the world. FX is traded 24/7 around the world. Sunday is a work day in Israel. Sunday is a work day in Israel. Buying and selling is done with computers, phone lines. Buying and selling is done with computers, phone lines. In short, FX market is truly global single market. In short, FX market is truly global single market. There should not be any price differentials from one place to another. There should not be any price differentials from one place to another.

14 Arbitrage Suppose $1=¥100 in New York but $1=¥101 in London. You work at the FX desk of Citibank. How would you make money for Citibank?

15 Arbitrage You buy USD in New York (sell ¥) and sell USD in London (buy ¥). You buy USD in New York (sell ¥) and sell USD in London (buy ¥). You borrow yen in New York, buy USD, exchange USD to yen in London and pay your yen debt. You borrow yen in New York, buy USD, exchange USD to yen in London and pay your yen debt. ¥100 million in New York will become ¥101 million in London. ¥100 million in New York will become ¥101 million in London.

16 Equilibrium FX Buying USD in New York will raise the price of $: $1 will be worth more than ¥100 or ¥100 will be worth less than $1. Buying USD in New York will raise the price of $: $1 will be worth more than ¥100 or ¥100 will be worth less than $1. Selling USD in London will lower the price of $: $1 will be less than ¥101 or ¥101 will be more than $1. Selling USD in London will lower the price of $: $1 will be less than ¥101 or ¥101 will be more than $1. Prices in New York and London will be $1=¥ Prices in New York and London will be $1=¥100.5.

17 Vehicle Currency If there are hardly any trade and asset purchases between two countries, they might not have inventories of each other’s currencies. If there are hardly any trade and asset purchases between two countries, they might not have inventories of each other’s currencies. Typically, USD is the international reserve currency that is used to exchange from one currency to another. Typically, USD is the international reserve currency that is used to exchange from one currency to another. USD acting as a vehicle currency allows to calculate cross rates. USD acting as a vehicle currency allows to calculate cross rates.

18 Cross Rates Suppose $1=¥100 and $1=SF0.75. Suppose $1=¥100 and $1=SF0.75. What is the cross rate between Yen and Swiss Franc? What is the cross rate between Yen and Swiss Franc? ¥1=$0.01 ¥1=$0.01 ¥1=$0.01(SF0.75/$) =SF ¥1=$0.01(SF0.75/$) =SF SF1=$1.33 SF1=$1.33 SF1=$1.33(¥100/$)=¥133 SF1=$1.33(¥100/$)=¥133

19 Spot and Forward Rates FX transaction that takes effect immediately (even if the funds cannot be cleared before two days) is a spot transaction. FX transaction that takes effect immediately (even if the funds cannot be cleared before two days) is a spot transaction. FX transaction that will take effect in the future (say one month or three months) is a forward transaction. FX transaction that will take effect in the future (say one month or three months) is a forward transaction. The difference between the spot and forward rates shows the interest rate differential between two currencies.

23 Spot and Forward You import VCRs from Japan. You have to pay ¥100 million in six months. Japanese funds pay 1% interest annually. You import VCRs from Japan. You have to pay ¥100 million in six months. Japanese funds pay 1% interest annually. You need ¥99,502, today to have the funds in six months: (1.005x=100,000,000). You need ¥99,502, today to have the funds in six months: (1.005x=100,000,000). You could exchange $795, today: [(¥99,502,487.56)/¥125.16/$]. You could exchange $795, today: [(¥99,502,487.56)/¥125.16/$]. You could keep your $795, and earn 2.8% interest so that you could exchange $806, at ¥ to pay ¥100 million. You could keep your $795, and earn 2.8% interest so that you could exchange $806, at ¥ to pay ¥100 million.

24 Spot and Forward If it doesn’t make any difference, i.e., it costs you the same amount today, why bother? If it doesn’t make any difference, i.e., it costs you the same amount today, why bother? Because in six months ¥/$ rate may be different. Because in six months ¥/$ rate may be different. If ¥/$ rate in six months turns out to be ¥120, you could only get ¥96,735, ($806,132.32)(¥120). If ¥/$ rate in six months turns out to be ¥120, you could only get ¥96,735, ($806,132.32)(¥120). By entering a forward contract with your bank you know exactly how much you are paying and can price your VCRs accordingly. By entering a forward contract with your bank you know exactly how much you are paying and can price your VCRs accordingly.

30 The Demand for an Asset The demand for an asset depends on the generated income (interest rate), capital gain (expected price), riskiness, liquidity. The demand for an asset depends on the generated income (interest rate), capital gain (expected price), riskiness, liquidity.

31 Rate of Return A $1000 bond that pays $50 provides an interest rate of 5%. A $1000 bond that pays $50 provides an interest rate of 5%. If you sell the bond for $1100, your rate of return is 15%. If you sell the bond for $1100, your rate of return is 15%. If you sell the bond for $900, your rate of return is -5%. If you sell the bond for $900, your rate of return is -5%. If inflation were 5%, your real rate of return would have been 10% and -10%, respectively. If inflation were 5%, your real rate of return would have been 10% and -10%, respectively.

32 Risk Risk is a measure of uncertainty of future returns. The higher the variations in returns, the higher is the risk. Risk is a measure of uncertainty of future returns. The higher the variations in returns, the higher is the risk. The higher the risk, the less desirable is the asset. The higher the risk, the less desirable is the asset.

33 Liquidity Liquidity is a measure of cost and speed to convert an asset into cash. The cheaper and speedier an asset can be converted to cash, the more liquid it is. Liquidity is a measure of cost and speed to convert an asset into cash. The cheaper and speedier an asset can be converted to cash, the more liquid it is. The more liquid an asset, the more desirable it is. The more liquid an asset, the more desirable it is.

35 Comparison of Returns Suppose the $/€ exchange rate is $0.93 per €. Suppose the $/€ exchange rate is $0.93 per €. What is the €/$ rate? What is the €/$ rate? It is the reciprocal, or 1/0.93 = €1.075

36 Comparison of Returns Suppose $ deposits pay 5% interest rate. Suppose $ deposits pay 5% interest rate. Suppose € deposits pay 8% interest rate. Suppose € deposits pay 8% interest rate. Which asset ($ or €) would you rather hold? Which asset ($ or €) would you rather hold? € of course.

37 Comparison of Returns Suppose you will need your $ a year from now. Today the exchange rate is $0.93/€. Suppose you will need your $ a year from now. Today the exchange rate is $0.93/€. You expect the $/€ rate to be $0.91. You expect the $/€ rate to be $0.91. Do you expect the $ to appreciate or depreciate? Do you expect the $ to appreciate or depreciate? Do you expect the € to appreciate or depreciate? Do you expect the € to appreciate or depreciate? Your expectation is for $ to appreciate and for € to depreciate.

38 Comparison of Returns The rate of appreciation of $ will increase the percentage return on USD. The rate of appreciation of $ will increase the percentage return on USD. The rate of depreciation of € will decrease the percentage return on €. The rate of depreciation of € will decrease the percentage return on €. If € is expected to move from $0.93 to $0.91, its rate of depreciation is ($0.91- $0.93)/$0.93 = or -2.15%. If € is expected to move from $0.93 to $0.91, its rate of depreciation is ($0.91- $0.93)/$0.93 = or -2.15%. The rate of appreciation for $ is (€ €1.075)/ €1.075= or 2.2%. The rate of appreciation for $ is (€ €1.075)/ €1.075= or 2.2%.

39 Comparison of Returns Since the appreciation/depreciation calculations are approximately equal, we will treat them to be equal for simplicity. Since the appreciation/depreciation calculations are approximately equal, we will treat them to be equal for simplicity. If we compare interest rate on $ (5%) with the returns on € (8% %), we are still better off keeping our wealth in €. If we compare interest rate on $ (5%) with the returns on € (8% %), we are still better off keeping our wealth in €. If we compare interest rate on € (8%) with the returns on $ (5% + 2.2%), again we are still better off keeping our wealth in €. If we compare interest rate on € (8%) with the returns on $ (5% + 2.2%), again we are still better off keeping our wealth in €.

40 Comparison of Returns R $ compared to R € + [($/€) e - ($/€)]/($/€) will show dollar returns in US versus dollar returns in Europe. R $ compared to R € + [($/€) e - ($/€)]/($/€) will show dollar returns in US versus dollar returns in Europe. R € compared to R $ + [(€/$) e - (€/$)]/(€/$) will show euro returns in Europe versus euro returns in the US. R € compared to R $ + [(€/$) e - (€/$)]/(€/$) will show euro returns in Europe versus euro returns in the US. If the exchange rate is always kept as ($/€), the euro returns comparison will be R $ - [($/€) e - ($/€)]/($/€) or appreciation of euro subtracted from R $. If the exchange rate is always kept as ($/€), the euro returns comparison will be R $ - [($/€) e - ($/€)]/($/€) or appreciation of euro subtracted from R $.

41 Comparison of Returns The difference between appreciation and depreciation is the result of simplifying the calculation. The difference between appreciation and depreciation is the result of simplifying the calculation. The correct calculation proceeds from exchanging a $ into €, earning interest on €, exchanging € back to $ and subtracting the principal ($1). The correct calculation proceeds from exchanging a $ into €, earning interest on €, exchanging € back to $ and subtracting the principal ($1). $1(€/$) [1+R € ] ($/€) e - $1 = [1+ R € ][($/€) e /($/€)] - [($/€)/($/€)] + R € [($/€)/($/€)] - R € [($/€)/($/€)] $1(€/$) [1+R € ] ($/€) e - $1 = [1+ R € ][($/€) e /($/€)] - [($/€)/($/€)] + R € [($/€)/($/€)] - R € [($/€)/($/€)]

42 Comparison of Returns Replace $/€ by E. Replace $/€ by E. =[1+ R][E e /E] - [E/E] + R [E/E] - R [E/E] =[1+ R][E e /E] - [E/E] + R [E/E] - R [E/E] = [RE e /E - RE/E] + R + [E e /E - E/E] = [RE e /E - RE/E] + R + [E e /E - E/E] = R[(E e -E)/E] + R + [(E e -E)/E] = R[(E e -E)/E] + R + [(E e -E)/E] When interest rate and appreciation/depreciation rate are small, the first term may be ignored. When interest rate and appreciation/depreciation rate are small, the first term may be ignored.

43 The Demand for Currency Deposits The difference in the rate of return on dollar deposits and euro deposits is The difference in the rate of return on dollar deposits and euro deposits is R $ - (R € + (E e $/€ - E $/€ )/E $/€ ) = R $ - (R € + (E e $/€ - E $/€ )/E $/€ ) = R $ - R € - (E e $/€ - E $/€ )/E $/€ expected rate of return = interest rate on dollar deposits interest rate on euro deposits expected rate of return on euro deposits expected exchange rate current exchange rate expected rate of appreciation of the euro

44 The Demand for Currency Assets

45 Applications $ interest rate is 10%; € interest rate is 8%. $ interest rate is 10%; € interest rate is 8%. Spot ($/€) rate is $0.93 per euro. Spot ($/€) rate is $0.93 per euro. If ($/€) e were (a) $0.95; (b) $0.91; (c) $0.97 where would you park your deposits? If ($/€) e were (a) $0.95; (b) $0.91; (c) $0.97 where would you park your deposits? (a) € appreciates by ( )/.93 = 2.15% 10% < 8% %. (b) € depreciates by ( )/.93 = % 10% > 8% %. (c) € appreciates by ( )/.93 = 4.3% 10% < 8% + 4.3%.

46 Equilibrium When returns from $ are the same as returns from euro, there will be no adjustments: the foreign exchange market between USD and euro is in equilibrium. When returns from $ are the same as returns from euro, there will be no adjustments: the foreign exchange market between USD and euro is in equilibrium. The returns are equal when the USD interest rate is exactly equal to euro interest rate plus the rate of appreciation of euro. The returns are equal when the USD interest rate is exactly equal to euro interest rate plus the rate of appreciation of euro. Alternatively, the returns are equal when the euro interest rate is equal to $ interest rate minus the depreciation of euro. Alternatively, the returns are equal when the euro interest rate is equal to $ interest rate minus the depreciation of euro.

47 Equilibrium Equilibrium in the foreign exchange market will take place when the interest parity condition holds. Equilibrium in the foreign exchange market will take place when the interest parity condition holds. R $ = R € + [($/€) e - ($/€)]/($/€) R $ = R € + [($/€) e - ($/€)]/($/€) If R $ > R € + [($/€) e - ($/€)]/($/€), there will be an excess demand for USD (excess supply of €) in the foreign exchange market. If R $ > R € + [($/€) e - ($/€)]/($/€), there will be an excess demand for USD (excess supply of €) in the foreign exchange market. If R $ < R € + [($/€) e - ($/€)]/($/€), there will be an excess demand for euro and an excess supply of USD. If R $ < R € + [($/€) e - ($/€)]/($/€), there will be an excess demand for euro and an excess supply of USD.

48 Current FX and Returns If the current FX goes up, e.g., euro appreciates today but the expected FX remains the same, the dollar return on euro deposits will decrease. If the current FX goes up, e.g., euro appreciates today but the expected FX remains the same, the dollar return on euro deposits will decrease. R € + [($/€) e - ($/€)]/($/€) will be lower if ($/€) rises. R € + [($/€) e - ($/€)]/($/€) will be lower if ($/€) rises. R $ - [($/€) e - ($/€)]/($/€) will be higher if ($/€) rises.
