Foreign Exchange Market
o definition – organizational setting within which
individuals, businesses, governments, and
banks buy and sell foreign currencies
o no single, central meeting place
o largest foreign exchange markets: London,
New York and Tokyo
o transactions between:
• commercial banks and their commercial
customers
• banks conducted by brokers
• trading banks and their overseas branches
Types of Transactions
o spot transaction - outright purchase & sale
of foreign currency with ‘immediate delivery’
meaning within two business days
o forward transaction – agreement for
purchase & sale at a specified rate at some
point in the future
• more than two business days
• months or even years in the future
o currency swap – conversion of one currency
to another at one point in time with agreement
to reconvert back at a specified future time
Interbank Trading
o most U.S. transactions conducted by a few
large banks
o retail transactions – bank to customers; less
than $1MM
o wholesale
transactions –
bank to bank
or bank to
corporate
customers;
more than
$1MM
Bank Profits on Transactions
o banks quote two rates on transactions:
•
•
bid rate – price bank is willing to pay for foreign
currency
offer rate – price at which bank is willing to sell
foreign currency
o spread – difference between the bid and offer
o other profits:
o anticipating appreciation => bank raises bid & offer
to buy more of that currency => resells later at high
price making a profit
o anticipating depreciation => bank lowers bid &
offer to sell more of that currency => buys back
later at lower price creating profits
Foreign Exchange Quotations
o 2nd and 3rd columns indicate number of dollars
needed to buy foreign currency
[0.03046 U.S. dollars for one Taiwan dollar]
o 4th and 5th columns indicate units of foreign
currency needed to buy dollar
[32.83 Taiwan dollars for one U.S. dollar]
Cross Exchange Rate
o most quotations expressed in terms of U.S. dollar
o cross exchange rate determines value of two
currencies in terms of a third
o example:
$ value of Taiwan dollar
= $.03046 = 27.9681
$ value of S. Korean won
$.0010891
Therefore, each Taiwan dollar buys approximately
28 South Korean won.
Forward Versus Futures Markets
Difference Associated with Futures Market:
o only at specific locations such as International
Monetary Market of Chicago Mercantile
Exchange and Tokyo International Financial
Futures Exchange
o only major currencies
o contracts limited to specific dates (3rd Wed.
March, June, September & December)
o fixed amounts
o profit/loss paid at close of trading as opposed
to the contract date
Foreign Currency Options
o definition – agreements between holder
(buyer) and writer (seller) giving the holder the
right to buy or sell a fixed amount of foreign
currency at a specified price within a specified
time period
o call option – provides right to buy
o put option – provides right to sell
o strike price – price at which the option can be
exercised
o holder not obligated to use contract; writer
obligated if holder proceeds with transaction
Exchange-Rate Determination
o demand for foreign currency corresponds to
balance of payments debits [U.S. imports; U.S.
foreign investment; foreign transfer payments]
o supply of foreign
currency equal to
balance of payment
credits [U.S.
exports; foreign
investment in U.S.;
transfer payments
to U.S.]
Appreciation of U.S. Dollar
Advantages:
1) U.S. consumers see lower prices on foreign
goods
2) lower prices on foreign goods limit U.S. inflation
3) U.S. consumers benefit during foreign travel
Disadvantages:
1) U.S. firms find it harder to compete in foreign
markets
2) U.S. firms find it harder to compete with imports
3) foreign tourists find it more expensive to vacation
in the U.S.
Depreciation of U.S. Dollar
Advantages:
1) U.S. firms find it easier to sell goods in foreign
markets
2) firms in the U.S. face less pressure to keep
prices low
3) more foreign tourists can afford to visit U.S.
Disadvantages:
1) U.S. consumers face higher prices on foreign
goods
2) higher foreign prices can lead to inflation in U.S.
3) U.S. consumers find foreign travel more costly
Nominal Exchange Rate
o exchange rate index – weighted average of
exchange rates between the domestic currency
and nation’s most important trading partners
o major currency index
– average exchange
rate for dollar versus
seven major U.S.
trading partners
o nominal index such
as this is not adjusted
for changes in U.S. or
foreign price levels
Real Exchange Rate
o accounting for changes in the price levels:
Real Exchange Rate = Nominal Exch. Rate × Foreign Country’s Price Level
Home Country’s Price Level
o better indication
of purchasing
power of dollar
o increase in real
exchange rate
will make it
more difficult for
U.S. firms to
compete
Arbitrage
o exchange arbitrage – simultaneous purchase
and sale of currency in different foreign
exchange markets in order to profit from
exchange rate differential in two locations
o two or three point arbitrage possible
assume: £1 = $1.50; £1 = 4 francs; 1 franc = $0.50
sell $1.5 million for £1 million
sell £1 million for 4 million francs
sell 4 million francs for $2 million
$500,000 profit
o such transactions shift supply & demand for
currencies eliminating opportunities for profits
and establishing consistent exchange rates
Forward Market
o currency worth more in forward market than spot
market => premium
o currency worth less in forward market than spot
market => discount
Forward Rate  Spot Rate

Spot Rate
Spot Rate No. Months Forward
Relationship Between Forward Rate
& Spot Rate
interest rate differentials - comparable securities
higher U.S. interest rates
o investors sell foreign currency for dollars
driving down spot price
o use dollars to purchase U.S. Treasury bills
o investors obtain forward contract allowing
foreign currency to be bought back with dollars
driving up forward price
o result: foreign currency at premium in forward
market
Relationship Between Forward Rate
& Spot Rate (cont.)
lower U.S. interest rates
o investors buy foreign currency with dollars
driving up spot price
o use foreign currency to purchase foreign
Treasury securities
o investors obtain forward contract allowing
dollars to be bought back with foreign currency
driving down forward price
o result: foreign currency at discount in forward
market
Managing Foreign Exchange Risk
o hedging – process of avoiding or covering a
foreign exchange risk
o U.S. importer hedging against depreciation
• must pay in foreign currency in the future
• contract to purchase foreign currency in the
forward market
• does not require importer to tie up funds
o exporter hedging against appreciation
• will receive foreign currency in the future
• contract to sell foreign currency in the
forward market
o both eliminate risks of fluctuating spot rates
Uncovered Interest Arbitrage
o moving funds
into foreign
currency to take
advantage of
higher rate of
return without
forward contract
o extra return:
UK
U.S.
Percentage
= Interest - Interest ± Appreciation/Depreciation
Rate
Rate
of Pound
Covered Interest Arbitrage
1) purchase foreign currency at spot rate and use it
to finance foreign investment
2) contract in the forward market to sell amount of
foreign currency that will be received
because of activity in the forward market such
investment opportunities quickly disappear
Foreign Exchange Market Speculation
o speculation – attempt to profit by trading on
expectations about prices in the future
o different from arbitrage where trader buys &
sells simultaneously; speculator buys at one
time and sells at a different time
o stabilizing speculation – goes against
market forces by moderating changes in
exchange rates
o destabilizing speculation – goes with market
forces by reinforcing fluctuations in exchange
rates
