Three Common Methods for Predicting Currency Exchange Rates

A foreign exchange rate prediction can assist brokers and businesses in making educated decisions that reduce risk and increase profits. There are several approaches for anticipating currency exchange rates. We’ll look at a number of the more prevalent methodologies, including purchasing power parity, relative economic strength, and econometric models, in this section.

Purchasing power parity (PPP)

Due to its indoctrination in most economic textbooks, purchasing power parity (PPP) is likely the most popular technique. The theory of one pricing, which asserts that equivalent items in different nations should have equal pricing, underpins the PPP forecasting technique. After taking into account the currency rate and deducting transaction and shipping charges, a pencil in Canada should cost the same as a pencil in the United States, according to purchasing power parity. To put it another way, there should be no arbitrage potential for someone to buy cheap pencils in one nation and profitably sell them in another.

Based on this core concept, the PPP methodology predicts that the exchange rate will vary to counteract price fluctuations due to inflation. Consider the following scenario: pencil prices in the United States are predicted to grow by 4% over the next year, whereas prices in Canada are predicted to grow by only 2%. This indicates that pencil costs in the United States are projected to climb quicker than in Canada. In this case, the buying power parity technique predicts that the US currency will have to drop by around 2% in order for pencil costs in both nations to remain substantially identical.



Relative Economic Strength

The relative economic strength methodology, as the name implies, considers the strength of economic growth in various nations in order to estimate exchange rate direction. This is very valid information for everyone who is involved in the forex market and especially, brokers who have to provide their clients with the information. Generally, the most frequently asked questions include the forex brokerage companies, which of them can be trusted, which of them provides better service, etc. one of the most efficient ways to decide on the company and choose for your trading process is to thoroughly analyze the reviews of popular Forex brokers and in general, the reviews include all the detailed information about the technical matters or comments from the former clients. To get back to the relative economic strength, the logic behind this strategy is that a robust economic environment with the potential for significant growth is more likely to attract foreign investment. Furthermore, in order to acquire investments in the target nation, an investor must first acquire the nation’s currency, resulting in higher demand for the currency, which should drive it to appreciate.

This method looks at more than simply the relative economic strength of countries. It examines all investment flows from a broader perspective. Interest rates, for example, are another element that might attract investors to a country. High-interest rates will attract investors searching for the maximum return on their investments, prompting demand for the currency to rise, resulting in a currency appreciation.

Unlike the PPP technique, the relative economic strength technique does not anticipate what the exchange rate should be. Rather, this method provides an investor with an overall idea of whether a currency will gain or depreciate, as well as the strength of the movement. To obtain a thorough result, it is usually used in conjunction with other forecasting approaches.

Economic Models

Another typical strategy for forecasting exchange rates is to collect elements that may influence currency movements and build a model that connects these variables to the exchange rate. The elements in econometric models are usually based on economic theory, although any variable can be included if it is thought to have a substantial impact on the exchange rate.

Consider the case of a forecaster for a Canadian corporation entrusted with predicting the USD/CAD exchange rate for the coming year. They feel that using an econometric model would be a useful way, and they have investigated aspects that they believe influence the exchange rate. The interest rate differential between the US and Canada (INT), the difference in GDP growth rates (GDP), and the income growth rate (IGR) variances between the two nations are the most relevant elements, according to their research and analysis.

The variables INT, GDP, and IGR can be inserted into the model after it has been established to generate a prediction. The coefficients a, b, and c will indicate how much and in which direction a given factor influences the exchange rate. This is the most complicated and time-consuming way, but once the model is in place, fresh data can be readily gathered and fed in to provide speedy forecasts.

Forecasting exchange rates is extremely difficult, which is why many businesses and investors just hedge their currency risk. Those who recognize the benefit of projecting exchange rates and wish to learn more about the elements that influence their movements might start their studies with these methods.
