Currency risk arises from exposure to the consequences of a rise or fall in an
exchange rate. Here, the German company was exposed to the risk of a fall in the
value of the US dollar.
An exposure lasts for a period of time. Here, the exposure lasts from when the
goods were sold on credit until the time that the customer eventually pays.
Currency risk is a two-way risk, and exposure to risk can lead to either losses or
gain from movements in an exchange rate. In this example, the exchange rate
could have moved the other way. For example, if the exchange rate after three
months had been $1 = €1, the German company would have received €330,000,
which is €30,000 more than it would have expected at the time of the sale. There
would have been an ‘FX gain’ of €30,000.
1.4 Government measures to stabilise exchange rates
A government may try to stabilise the exchange rate for its currency. The purpose of
having an exchange rate policy would be to create stable economic conditions for
international trade. A stable exchange rate, with relatively little exchange rate
volatility, should help to promote growth in the country’s economy.
In the past, some governments were able to manage the exchange rate by dealing on
the foreign exchange markets, using their official reserves of foreign exchange to
either buy or sell domestic currency. By creating demand or supply for its currency
in the markets, the government would try to move the exchange rate up or down
against major currencies such as the dollar. However, the foreign exchange markets
are now so large that very few countries are in a position to manage the exchange
rate effectively in this way. (Countries such as China may be an exception.)
The most effective way for a government to manage its exchange rate today, if it
wished to do so, would be to increase or reduce domestic interest rates on its
currency. Raising or reducing interest rates should affect the demand for the
currency from investors. For example, raising the interest rate should attract more
investment into the currency, and by increasing demand for the currency, the
foreign exchange value of the currency should increase.
There are several exchange rate policies that a government might adopt. These
include:
free floating (‘benign neglect’ of the exchange rate)
managed floating of the currency
a fixed exchange rate policy, with the exchange rate fixed against a major
currency or a basket of world currencies
a fixed exchange rate backed by a currency board system.
Free floating
With a policy of free floating, the government does not have a policy about the
exchange rate. Instead, it allows the currency to find its own market value in the
foreign exchange markets.
