3. Cost and Management Accounting: An Introduction, 7 th edition Colin Drury ISBN 978-1-40803-213-9 © 2011 Cengage Learning EMEA Measuring Exchange Rate Movements (1) An exchange rate measures the value of one currency in units of another currency. When a currency declines in value, it is said to depreciate. When it increases in value, it is said to appreciate. On the days when some currencies appreciate while others depreciate against a particular currency, that currency is said to be “mixed in trading.” International Financial Management, 2 nd edition Jeff Madura and Roland Fox ISBN 978-1-4080-3229-9 © 2011 Cengage Learning EMEA

4. Cost and Management Accounting: An Introduction, 7 th edition Colin Drury ISBN 978-1-40803-213-9 © 2011 Cengage Learning EMEA Foreign Exchange Rate Determination Exchange rate determination is complex. Some argue that there are three major schools of thought (parity conditions, balance of payments approach, asset market approach) These are not competing theories but rather complementary theories. Without the depth and breadth of the various approaches combined, our ability to capture the complexity of the global market for currencies is lost.

6. Cost and Management Accounting: An Introduction, 7 th edition Colin Drury ISBN 978-1-40803-213-9 © 2011 Cengage Learning EMEA Exchange Rate Determination: The Theoretical Thread The theory of purchasing power parity is a widely accepted theory of exchange rate determination: –PPP is the oldest and most widely followed of the exchange rate theories, and deals with exchange rates and inflation. Countries who suffer from high inflation, will se a deterioration in the value of their currency –Most exchange rate determination theories have PPP elements embedded within their frameworks. –We will look at PPP in more detail in chapter 8

7. Cost and Management Accounting: An Introduction, 7 th edition Colin Drury ISBN 978-1-40803-213-9 © 2011 Cengage Learning EMEA Exchange Rate Determination: The Theoretical Thread The balance of payments approach is also a widely utilized theoretical approach in exchange rate determination: –The basic approach argues that the equilibrium exchange rate is found currency flows match up vis a vis current and financial account activities. –If a country suffers from prolonged BOP deficits, the value of its currency will fall

8. Cost and Management Accounting: An Introduction, 7 th edition Colin Drury ISBN 978-1-40803-213-9 © 2011 Cengage Learning EMEA Exchange Rate Determination: The Theoretical Thread The asset market approach argues that exchange rates are determined by the supply and demand for a wide variety of financial assets: –Shifts in the supply and demand for financial assets alter exchange rates. –Changes in monetary and fiscal policy alter expected returns and perceived relative risks of financial assets, which in turn alter exchange rates.

A positive %  represents appreciation of the foreign currency, while a negative %  represents depreciation.

The potential returns from foreign currency speculation are high for banks that have large borrowing capacity. The simple strategy is to get out of the currency about to depreciate and into the currency that is going to appreciate against it. Then reverse the positions after the event to end up with more than you started with.
