Determinants of Forex Trading Rates

In the world of foreign exchange trading (forex), the rates could not be determined or decided just as how the traders would like. Instead, the rates fluctuation in foreign exchange may vary.

One of the determinants that can be used to understand the fluctuation rates is the international parity conditions. This determinant includes the parity of purchasing power as well as good parity of interest rate, International Fisher Effect and Domestic Fisher Effect. These are the theories that offer logical explanation about fluctuations in the rates of foreign exchange. However, these theories are based on assumptions that can still be challenged because they seldom happen in the foreign exchange market in the real life. These include free goods flow as well as services and capital.

The other factor that is also of great importance is how well balanced the payment model is. The payment model puts a significant focus on services as well as goods that are eligible for trade. However, the payment model does not care about the global flows of the capital which has an ever-increasing role. The payment model failed as well in terms of providing proper explanation for the appreciation trends of dollar that has been lasting continuously since the year 1980. The payment model did not succeed either in explaining the deficit that to the account of the United States that took place in the 1990s.

Another determinant factor that needs to be taken into consideration while attempting to determine the foreign exchange rates is the model of the asset market.

In this kind of model, currencies are viewed and considered to be asset class that is of some certain levels of importance in order to be able to construct the portfolios for investments.

Most of the prices of the assets that are available are affected by how willing people are to hold their existing assets quantities that they have already had in possession. But before people make up their mind to keep their existing assets, they will want to think over at first how much the assets they already possess will be worth at the future.

This model of asset market as the determination factor of the foreign exchange rates mentions that the rate of exchange that exists in between two different currencies represents price balancing relative supplies of as well as demand for the assets available that are denominated in the currencies.

However, there has not been any model yet that can smoothly explain the levels of the foreign exchange rates as well as long term volatility.
