Final answer:
An exchange rate is the value of one currency expressed in terms of another, determined by supply and demand in markets, and can be influenced by government policies.
Step-by-step explanation:
In international trade, an exchange rate is a number that is used to show the value of one currency compared to another. It is not a way to record a nation's imports and exports, an agreement between nations to reduce trade barriers, nor a chart for keeping track of prices on a stock exchange.
The exchange rate serves as a crucial price—the price of one currency expressed in terms of units of another currency. Key factors such as supply and demand in markets are instrumental in determining the exchange rates. Governments can manipulate exchange rates through various mechanisms, like adjusting interest rates and altering trade incentives, which ultimately influence the global trade dynamics.
