Factors that Determine the Currency Exchange Rates Exchange rate is often referred to as the nominal exchange rate. It is defined as the rate at which one currency can be converted, or 'exchanged', into another currency. For example, the pound is currently worth about 1.824 US dollars. One pound can be converted into 1.824 dollars. This is the exchange rate between the pound and the dollar. There are four types of currencies can be operated, which are a floating, managed and fixed exchange rate. Lots of developed industrial nations like US (\$), UK (ï¿¡) and Japan (ï¿¥) operate floating exchange rates. A floating exchange rate is known as freely floating and should be self-regulating. It is often determined by the market demand and supply without any other government or official interference. As the exchange rate between pound and dollar for example, the price of pound in terms of dollar would decided by the demand for pounds from whom hold dollars and the supply of pounds from sterling holder who want to buy dollars. When people in the UK try to buy US goods and services they will supply pounds to US, however, when people from US try to by UK goods and services they will demand UK pounds. At this time, the price which keeps the demand and supply force in balance is the exchange rate between pound and dollar. As it shows in [IMAGE]Price of ï¿¡s in \$s S D \$1.5 (FIGURE 1.1) D S 0 Q Quantity ofï¿¡s figure1.1, when one pound equals one and a half dollars, the price is in equilibrium. Although floating exchange rate is mainly affect by market forces, actually sometimes a nation's central bank try to influence the exchange rate. They can use the way of adjusting the interest rate to influence the capital flow into or out of the country or directly buying or selling the currency. The reason central bank try to manage the exchange rate is to reduce the fluctuations around the equilibrium
