There is a great deal of academic theory revolving around currencies. While often not applicable directly to day-to-day trading, it is helpful to understand the overarching ideas behind the academic research The main economic theories found in the foreign exchange deal with parity conditions. A parity condition is an economic explanation of the price at which two currencies enter be exchanged, based on factors such as inflation and interest rates. The economic theories suggest that when forex parity condition does not hold, an arbitrage opportunity exists for market participants. Appliances, arbitrage opportunities, as in many other markets, are quickly discovered and eliminated before even giving the individual investor enter opportunity to capitalize on them. Other theories are based on economic factors such as trade, capital flows and the way a country runs its operations.

The balance of payments theory looks at the current account, which is the account dealing with trade of tangible goods, to get an idea of exchange-rate directions. To bring the current account back into equilibrium, the exchange rate will need to adjust over time. If a appliances is running a large deficit more imports than exportsthe domestic currency will depreciate. On the other hand, a surplus would lead to currency appreciation.
