National Currency

National currency is the official money used within a country for transactions, savings, and investments. It is issued and regulated by a country's central bank or monetary authority. Each country has its own currency, like the US Dollar in the United States or the Euro in the Eurozone. The value of national currency can fluctuate based on economic factors, including inflation, interest rates, and trade balances. National currencies facilitate trade and economic activity by providing a standard medium of exchange, a unit of account, and a store of value, helping economies function effectively on both domestic and international levels.
