Exchange rate systems
An exchange rate system is an agreement between countries on how exchange rates should
be determined
Floating currency is a currency whose exchange rate is determined by demand for and supply
of the currency in foreign exchange markets
Managed float exchange rate system is the same as a floating currency, but with occasional
central bank or government intervention
Fixed exchange rate system is where two countries keep their exchange rates fixed
The current exchange rate system
Three important aspects
o Australia, Britain and the US allow their currencies to float against other currencies with
some intervention from central bank or government
o Most countries in Western Europe are in the euro zone and use the same currency
o Some developing countries aim to keep their exchange rate fixed with major currencies
like the USD
The floating dollar
o The Australian dollar was floated in December 1983
o Since then it has fluctuated widely against other major currencies
o The Trade Weighted Index (TWI) measures the value of the AUD against a 'basket' of the
currencies in Australia's main trading partners
What determines exchange rates in the long run?
o Purchasing power parity: This is the theory that in the long run, exchange rates move to
equalise the purchasing power of different countries
Things against purchasing power parity
Not all products can be traded internationally
Products and consumer preferences are different across countries
Countries impose barriers to trade
o Barriers to trade include tariffs and quotas
There are four determinants for exchange rates in the long run
o Relative price levels
o Relative rates of productivity growth
o Preferences for domestic and foreign goods
o Tariffs and quotas
The euro
o Economists disagree over whether a common currency helps economic growth
o A common currency makes trade easier and cheaper, thereby encouraging competition
o However countries can no longer operate an independent monetary policy, but can have
their own fiscal policies
o Also, a country in recession will not experience a currency depreciation, which would
revive exports
Pegging against the USD
o Pegging: the decision by a country to keep the exchange rate fixed between its currency
and another currency
o Pegging makes business planning easier, fixes foreign debt levels and payments and
reduces fluctuations in import prices
o However it can create problems
Can lead to persistent surpluses or shortages of currency
