International financial management would be no different than domestic
financial management were it not for the fact that at the international level problems are
introduced by two factors: the presence of different countries and the presence of
different currencies. This is an important distinction, because the domain over
which countries are defined (political divisions) is different from the domain over which
currencies are defined (currency areas, or areas within which exchange rates are fixed).
For example, different countries may use a common currency; Panama and the USA both use
the US dollar, and on a larger scale one of the ultimate aims of the European community is
to introduce a common currency for all of Europe. Similarly, it is possible to deal in
different currencies within a given country; term deposits denominated in various
currencies are commonplace in the major international financial centres.
A consequence of the existence of countries and currencies is the
need for international financial managers to assess and manage political and exchange rate
exposure and risk. As explained below, exposure represents the amount at
risk while risk relates to the dispersion of possible outcomes. Exposure and risk are
therefore conceptually and even dimensionally different. However, at the same time as
countries and currencies create special problems they also create special opportunities,
including higher returns and/or better diversification than is possible in any one country
or currency. If exposures and risks are to be properly managed, then it is necessary that
they be correctly measured. However, while measurement is in principle straightforward,
there are major problems in practice.
The key concepts are the balance of payments (the record of
transactions between domestic residents and residents of foreign countries over a period
of time) and the exchange rate; important issues include the relationship between exchange
rate policy and monetary policy, and the link between the balance of payments and the
exchange rate. The most prominent models of exchange rate determination are the
neoclassical or monetarist model and the Keynesian model, which distinguishes between
internal and external equilibrium and makes calculations assuming prices are fixed in the
short run. More recent models emphasize the role of international capital movements.
Current issues in international finance include the role of the International Monetary
Fund and the World Bank, the development of the European Monetary System and whether
efficient markets hypothesis can be applied to exchange rates.
