The paper and coin money a country uses for buying and selling goods and services, saving and paying debts. The United States has a currency made up of dollars, quarters, nickels, and pennies, among other things. Just about every country has its own currency, but there are also some global currencies that are used worldwide.
A currency is a medium of exchange that has the backing of a government and that people trust to hold its value over time. This makes it easier to trade products and services than relying on bartering. Currency also sets a standard of value, making it easier to compare prices and quality of goods from different countries.
The value of a currency can change depending on the supply and demand for that currency. For example, a country might experience inflation, which can make its domestic products more expensive and less attractive to foreigners. This can reduce the demand for a nation’s currency, and its value will fall. On the other hand, a country might have low interest rates, which can attract investment and increase the demand for its currency, driving its value up.
A currency’s value can also fluctuate due to its relation to other world currencies. This is called the exchange rate. An exchange rate tells you how much one country’s money is worth in another country’s currency. For example, if you want to buy a Big Mac in Germany, you’ll need to know the exchange rate between the Euro and the US Dollar.
