International currency exchange rates show how much it is possible to exchange one unit of a currency for another currency. Currency exchange rates may float, in which case they are constantly changing on the basis of a variety of factors, or they may be pegged (or fixed) to another currency, in which case they are still floating, but they are moving in tandem with the currency they are pegged to.
It helps investors to analyse assets priced in foreign dollars by knowing the value of a home currency in relation to various foreign currencies. For example, knowing the dollar to euro exchange rate is valuable for a U.S. investor when choosing European investments. Just as an increasing U.S. dollar value could hurt the value of your foreign investments, a decreasing U.S. dollar could increase the value of foreign investments.
Floating rate vs Fixed Rate
You can determine currency prices in two main ways: a floating rate or a fixed rate. Through supply and demand on global currency markets, a floating rate is determined by the open market. Therefore, the value will increase if the demand for the currency is high. If demand is low, this will drive down the price of that currency. Certain technical and fundamental factors will, of course, determine what people perceive to be a fair exchange rate and change their supply and demand accordingly.
The government, through its central bank, determines a fixed or pegged rate. The rate (such as the U.S. dollar, euro, or yen) is set against another major world currency. The government will buy and sell its own currency against the currency it is pegged to in order to maintain its exchange rate.
China and Saudi Arabia include some countries that choose to peg their currencies to the U.S. dollar.
After the collapse of the Bretton Woods system between 1968 and 1973, the currencies of most of the major economies in the world were allowed to float freely. Therefore, most exchange rates in the world’s currency markets are not set but are determined by on-going trading activity.
How exchange rate is influenced?
The market forces of supply and demand determine floating rates. How much demand exists in relation to a currency’s supply will determine the value of that currency in relation to another currency. For example, if Europeans’ demand for U.S. dollars increases, the supply-demand relationship will cause the price of the U.S. dollar to increase relative to the euro. There are countless geopolitical and economic announcements affecting exchange rates between the two countries, but some of the most common include changes in interest rates, unemployment rates, inflation reports, numbers of gross domestic products, data on production and commodities.
Short-term moves reflect speculation, rumours, disasters, and everyday supply and demand for the currency in a floating exchange rate currency. If supply outstrips demand, the currency will fall, and the currency will rise if demand outstrips supply. Even in a floating rate environment, extreme short-term moves can result in intervention by central banks. Because of this, while most major global currencies are considered floating, if the currency of a nation becomes too high or too low, central banks and governments may step in.
Too high or too low a currency could have a negative impact on the economy of the nation, affecting trade and the ability to pay debts. In order to move their currency to a more favourable price, the government or central bank will try to implement measures.
