Exchange Rate

What Is an Exchange Rate?

The value of one currency in terms of another is represented by an exchange rate. It denotes the quantity of one currency that can be converted into another. The amount of one currency that may be exchanged for a fixed amount of another currency, such as one US dollar or one euro, is commonly stated as the exchange rate.

Definition 2

Exchange Rate is the rate that would apply when changing the money (currency) of one country to that of another country.

More Thorough Understanding of the Term

The market forces of supply and demand affect exchange rates. The value of a currency, like any other asset, is decided by the number of individuals who want to purchase it vs. the number of people who want to sell it. When more people want to buy a specific currency, its value rises relative to other currencies. When more people want to sell a particular currency, the value of that currency falls.

The amount of a currency that is available for sale determines its supply. This covers currency held by individuals, businesses, and governments. The amount of a currency that people wish to buy determines its demand. Individuals who wish to go to a foreign country, businesses who want to import goods from a foreign country, and investors who want to invest in assets denominated in that currency are all included.

Importance of Exchange Rate

Exchange rates are important for a variety of reasons. Here are a few of the most significant:

  • Exchange rates have a significant impact on the cost of products and services traded across borders. The pricing of goods and services in both nations can be affected if the exchange rate between the two currencies changes.
  • Exchange rates also have an impact on investment decisions. If investors expect a currency to rise in value, they will frequently invest in assets denominated in that currency.
  • The cost of travel is affected by exchange rates. Travel to a country will be less expensive if its currency is weak in comparison to other currencies. 
  • Exchange rates are used by central banks to achieve their economic goals. 


Example 1

When visiting a foreign country, you must exchange your home currency for the currency of the country you are visiting. The exchange rate in effect at the time of your transaction will decide how much foreign currency you can purchase for each unit of your native currency. For example, if you are a US citizen visiting Europe and the exchange rate is 1 euro to 1.20 US dollars, you will receive 1 euro for every 1.20 US dollar you convert.

Example 2

If the exchange rate between the US dollar and the Japanese yen is 1 US dollar to 110 yen and changes from 1 US dollar to 100 yen, Japanese goods will become more expensive for US consumers while US goods will become more affordable for Japanese consumers.
