The Determinants of Exchange Rates in a Floating Exchange Rate system

To understand how a country’s currency might appreciate or depreciate, you must understand the variable that can affect demand or supply for the currency on the forex market. This lesson will introduce a useful acronym (TIPSY) for remembering the determinants of exchange rates, and evaluate the advantages and disadvantages of floating exchange rate systems.

Calculating Exchange Rates from Linear Equations

An exchange rate is simply an equilibrium price in a market for a currency, and like the prices of other goods, services and resources, a currency’s value can be calculated if the equations for supply and demand are known. This lesson will demonstrate how to calculate an equilibrium exchange rate from linear equations, and in part 2 demonstrate how an intervention by a central bank can lead to a change in demand or supply of a currency and thus trigger a change in its value.
