Exchange rates defined

An exchange rate is the value, or price, of one currency compared to another currency. Exchange rates are written in two ways, depending on which way you want to exchange. For example, the US dollar to euro relationship can be written as:

  • 1 USD = 0.901241 EUR
    This tells you how many euros you can buy with $1.
  • 1 EUR = 1.10958 USD
    This tells you how many US dollars you can buy with €1

Two types of currency pairs exist in the world: fixed and flexible.

Flexible currencies

Exchange rates that shift constantly and are determined by the maximum amount someone is willing to pay for a currency and the minimum amount someone is willing to sell it for — similar to stocks. The globally accepted exchange rates are what you see when you search a currency pair on Google or XE. These are known as the mid-market rate, short for the middle-market.

Fixed currencies

Opposite of flexible currencies, these are designed to maintain a consistent exchange rate with certain currency pairs. A country may fix or “peg” its currency to another currency with it trades with. This can help increase stability between the two countries for imports and exports. The Chinese yuan is pegged to the USD, and generally stays around 1 USD = 7 CNY.

How to use an exchange rate

If you’re traveling from the US to France, you need to exchange your dollars for euros at a bank or foreign exchange counter. The amount of euros you get for each dollar depends on the exchange rate between the two currencies at the time. If the exchange rate is roughly 0.90, for example, you’ll get 0.90 euros for each dollar you exchange. At this price, $100 will buy you about €90.

Understanding the impact of foreign currency exchange rates

Foreign exchange rates can have a strong impact on travelers, students and businesses that deal in foreign currencies.

  • Impact for tourists traveling abroad. If you’re visiting a country and the value of your currency falls against the other currency, your trip becomes more expensive. You’ll have to spend more money on hotels, travel, goods and attractions.
  • Impact for exporters. If you export products, the exchange rate between foreign currencies can impact your revenue. For example, if you sold goods in Canada for $1, and the CAD to USD exchange rate was 1.00, your sale is worth $1 USD. However, if the Canadian dollar appreciated against the US dollar to an exchange rate of 1.25, that $1 CAD sale is now worth $1.25 USD.
  • Impact on students. Student paying tuition and course fees in a foreign currency could see fees increase if exchange rates between the currencies increase.

How to get the best exchange rate

Getting the best exchange rate depends on your situation and the currency you are exchanging. Here’s how to get the best exchange rate in the following situations:

  • International transfers: Look to money transfer companies that specialize in offering the mid-market rate while checking that the fees you are paying are worth it.
  • International travel: Seek out local banks, post offices or even an ATM. Avoid exchange bureaus in tourist areas and airports.
  • US exchanges: If your bank operates internationally it may be the best place to get the lowest rate.
