Lecture Tip: The opportunity to exploit a triangle arbitrage may appear
to be an easy opportunity to make a quick profit. Point out that arbitrage
opportunities are rare and that the transaction costs for small investors
would likely outweigh any profit opportunity available.
Types of Transactions
Spot trade – exchange of currencies at immediate prices (spot rate)
Forward trade – contract for the exchange of currencies at a future date at
a price specified today (forward rate)
Premium – if the forward rate > spot rate (based on $ equivalent or direct
quotes), then the foreign currency is expected to appreciate and is selling
at a premium
Discount – if the forward rate < spot rate (based on $ equivalent or direct
quotes), then the foreign currency is expected to depreciate and is selling
at a discount
Slide 31.14 Types of Transactions
Lecture Tip: Well-known economist Milton Friedman provides a primer
on exchange rates in the November 2, 1998, issue of Forbes magazine. He
describes three types of exchange rate regimes.
Fixed rate or unified currency: “The clearest example is a common
currency: the dollar in the U.S.; the euro that will shortly reign in the
common market … the key feature of the currency board is that there is
only one central bank with the power to create money.”
Pegged exchange rate: “This prevailed in the East Asian countries
other than Japan. All had national central banks with the power to create
money and committed themselves to maintain the price of their domestic
currency in terms of the U.S. dollar at a fixed level, or within narrow
bounds – a policy they had been
encouraged to adopt by the IMF … In a world of free capital flows, such a
regime is a ticking time bomb. It is never easy to know whether a [current
account] deficit is transitory and will soon be reversed or is the precursor
to further deficits.”
Floating rates: “The third type of exchange rate regime is one under
which rates of exchange are determined in the market on the basis of
predominantly private transactions. In pure form, clean floating, the
central bank does not intervene in the market to affect the exchange rate,
though it or the government may engage in exchange transactions in the
course of its other activities. In practice, dirty floating is more common:
The central bank intervenes from time to time to affect the exchange rate
but does not announce in advance any specific value it will seek to
maintain. That is the regime currently followed by the U.S., Britain, Japan
and many other countries.
