What Is an Exchange Rate?

Exchange Rate refers to the price at which one currency can be exchanged for another. It plays a central role in international trade and finance, influencing everything from travel costs and import/export prices to investment returns and central bank policy. Exchange rates can be floating—determined by market forces—or fixed by governments or monetary authorities.

Types of Exchange Rates

How Exchange Rates Are Determined
- Exchange rates fluctuate based on various factors including:
- Supply and Demand: Currency demand rises with increased trade, investment, or speculation.
