Currency is anything that is used as a medium of exchange; most commonly known as monetary unit (money). The value of one's currency is determined by its economic power, its GDP (Gross Domestic Product) which represents the total dollar value of its goods and services produced over a period of time and the trade value of a nation. The higher a countries currency is the more expensive its exports will be and its imports cheaper in foreign markets. For lower currencies their exports will be cheaper and imports more expensive in foreign markets. All inclusive to a countries determining factors are a countries military status, its credibility and its power. Who ever holds the power holds the value.
" The government issuing flat currency takes the primary responsibility in setting its value. When a government prints fiat money, it is acting as a creditor in the sense that it promises the money is worth something. If a government does not back the value of its currency through an appropriate level of taxation, the money loses value. This is why budget deficits, national debts and central bank interest rates have an impact on what a currency is worth. Strong backing on the part of the public, strong economic performance and a healthy private banking sector can all mitigate this, however." - ehow
