Which factor plays a role in establishing the price of a country's currency?

Several factors influence the price of a country's currency, with supply and demand being paramount. Economic indicators such as interest rates, inflation, and GDP growth significantly impact investor confidence and currency valuation. Political stability and economic performance also play critical roles, as they affect foreign investment and trade balances. Additionally, speculation in the foreign exchange market can lead to fluctuations in currency prices based on traders' perceptions of future economic conditions.
