Expert forecasters of foreign exchange rates are extremely hard-working, detail-oriented, and dedicated individuals to seeking out the truth, analyzing it, and then providing information to providers and consumers. Billions of people all over the world depend on forecasting information for exchange rates, which is used for major financial and economic decisions to be made for countries and their currencies. In this article, we wanted to offer some insight into how to forecast exchange rates so you can see the amount of work that goes into this job.
Learning how to forecast exchange rates requires special education and training. For this, a computation of different values for a currency versus another currency is captured and analyzed over a certain amount of time. To accomplish this, a professional forecaster will choose from a long list of theories. However, regardless of the one chosen, limitations exist for each. In fact, to date no single model has been developed to create a monopoly within the process for how to forecast exchange rates.
Even so, there are two approaches that forecasters prefer, which are outlined below.
Fundamental Approach
The first approach regarding how to forecast exchange rates is designed so factors being considered work for long-term cycles. In this case, basic data specific to a country, as well as inflation rates, trade balance, unemployment rate and productivity indices are used. By using this particular approach, the forecaster is able to determine the true value or worth of the currency being worked in the future. For this reason, the Fundamental Approach is the best approach for long-term investments.
Technical Approach
This second approach associated with how to forecast exchange rates is more technical. With this, the concept is so investors would have the ability to determine any change in a particular exchange rate, which then allows predictions to be made by charting patterns. In this case, tools used include FX dealer to customer flow data, moving average trend-following trading rules, positioning surveys, and others. This approach is the preferred choice for patterns so informed decisions could be made specific to short-term investments.
In addition to approached playing a role in how to forecast exchange rates are models. Again, several models exist but the following are the ones that professional forecasters prefer.
• Uncovered Interest Rate Purity – Also referred to the UIP Model, this one forecasts movements of exchange rates in line with returns on investment using two different currencies. The benefit of this model is that it creates an arbitrage mechanism in which the exchange rate can equalize returns for both domestic and foreign assets.
• Purchasing Power Parity – This model is referred to the PPP Model that includes the study of exchange rate movements using each country’s price level change.
• Random Walk – The last Model specific to how to forecast exchange rates is this, which assumes that all available data regarding movement on exchange rates in the future would reflect the current exchange rate. Additionally, the assumption is that any future activity that would lead to change in exchange rates is simply random. Because of this, the Random Walk Model is the best option when forecasting a currency’s value based on current value. Of all models used, this one is by far the easiest.
