Frequently Asked Questions (FAQs)

What is the importance of a key currency?

The term "key currency" refers to significant currencies used as a reference in financial trade in the global economy.

Smaller countries' exchange rates are influenced by central banks' holdings of key currencies as reserve currencies. An exchange rate denotes the value of one nation's currency concerning another nation's currency, and it involves both foreign and domestic currency.

However, reserve currencies may or may not always be considered as the key currency. Still, they aid in paying foreign debt obligations, completing global transactions, and supporting investments.

Furthermore, nations retain key currencies for various purposes, including payment for various globally traded commodities like gold and oil and influence their domestic exchange rate. Setting the national currency to a key currency limits the monetary policy's flexibility; it boosts trust in its economy.

Additionally, when various countries agree on a deal, they usually utilise a key currency for transaction purposes to minimise the risk of currency exchange rate fluctuations during the deal's lifespan.

Developing and underdeveloped countries that do not retain key currencies often peg their national currencies to key currencies to facilitate international trade and maintain economic stability. Nations with less-dominant economies will align their exchange rates with the leading trade partner as a financial procedure.

What are the seven major key currencies?

1. The U.S. Dollar (USD) – The United States of America's official currency is the United States dollar (USD), which is comprised of 100 cents and denoted by the symbols US$ or $ to distinguish it from other dollar-based currencies.

Furthermore, the U.S. dollar is regarded as a benchmark currency and is the most widely utilised currency in international payments. The use of the USD is not confined to the United States; numerous territories outside of the United States utilise it as their official currency. Also, several nations make use of it along with their own as an unofficial currency.

The United States dollar has climbed to the peak of all other currency units globally during the last seven decades by emerging into an international medium of exchange, fostering global trade and investment in a more secure environment.

So, here's how the U.S. dollar got to number one as the world's most significant currency. The United States' hegemony in global commerce, foreign direct investment, gross domestic product (GDP), capital flows, and currency stability are the primary factors that lead to it becoming a preferred choice for firms and investors.

Notably, any nation has chosen to invest in U.S. dollar-denominated assets because of their global worth and stability. It also can offer the most liquid bond market.

Moreover, treasuries are regarded as the world's best risk-free asset, with U.S. treasuries yielding more than European and Japanese treasuries.

2. The Euro (EUR)- It is the official currency of the European Union (E.U.), with the symbol €, and is regarded as the world's second most key currency after the U.S. dollar due to its extensive use.

Furthermore, the European Economic and Monetary Union (EMU) is made up of 27 countries, 19 of which have embraced the Euro as their official currency.

There are several significant advantages to using the Euro as the official currency, including removing exchange rate risk for financial institutions and eurozone companies doing business in an increasingly globalised economy.

5. Canadian Dollar (CAD) - The currency symbol C$ stands for the Canadian dollar, which comprises 100 cents. However, the symbol C$ distinguishes CAD from other currencies denominated in dollars, such as the U.S. dollar, and CAD is often known as the "loonie".
