vaihtokykyn
Vaihtokykyn, also known as exchange rate, is the rate at which one currency will be exchanged for another. It is determined by the market forces of supply and demand, and is influenced by various factors such as economic indicators, political stability, and global events. The exchange rate can be either fixed or floating. A fixed exchange rate is set by the government and remains constant, while a floating exchange rate fluctuates based on market conditions. The exchange rate is typically quoted as the amount of one currency needed to buy another currency. For example, if the exchange rate between the US dollar and the euro is 1.20, it means that one US dollar can buy 1.20 euros. Exchange rates are crucial for international trade, tourism, and investment, as they affect the cost of goods and services, and the profitability of businesses operating in multiple countries. They are also used by central banks to manage a country's monetary policy and influence its economy.
