Currency is the most important form of money in the present world. But it was not always like this. Earlier, coins usually made of gold or silver was used as a form of money. Coins have a natural or inherent value. Gold coins were used for large purchases while silver or copper coins were used for smaller purchases during the medieval period. However, this has been replaced with banknotes. Banknotes are worthless otherwise in terms of natural or inherent value unlike gold coins. These banknotes get the value by decree of the government who declare the banknotes as money.
Currency exchange is used to facilitate trade in good and services between countries that have different currencies. The trade in goods and services using various currencies become possible with exchange rates between any two currencies. The monetary authority that determines the production and distribution of the currencies as well as influences the value of the currency with reference to other currencies is usually the country’s Ministry of Finance or the central bank. For instance, in the United States it is the Federal Reserve System.
In some countries the currencies are known by the same name. Dollar is the name used for the currencies in countries as the United States, Canada, Malaysia, Singapore, Zimbabwe, Australia and many more. Other currency names that are common to many countries include Dinar, Escudo, Franc, Frank, Gulden, Lira, Krone, Livre, Mark, Peso, Pound, Real, Rial, Ruble, Rupee, Scudo, and Shilling. There are also instances of the same currency being used by many countries such as the Euro in the European Union. Sometimes, a currency of another country may be accepted as a legal tender such as the US Dollar in El Salvador and Panama. Currencies are traded in the foreign exchange market both for purposes of international trade and speculative trading of currencies.

The demand of a currency will determine its exchange rate with reference to another currency. The value of the currency increases when the supply is limited but demand increases. The value of the currency declines when the demand is low as compared to the extent of supply.
