EURUSD is a currency pair that represents the value of the Euro against the US dollar.

The Euro, the currency adopted by 20 of the 27 European Union member states, has been in circulation since January 1999. According to the 2022 BIS Triennial Central Bank Survey, the Euro ranks second in trading volume, following the US dollar. The EURUSD currency pair accounts for over 20% of total trading volume across all currency pairs. Notably, the Euro's price movements often reflect not only the overall economic indicators of the Eurozone but also the economic data from key countries such as Germany and France.

The US dollar, issued by the United States, is circulated worldwide and holds the largest share in global foreign exchange. The 2022 BIS Triennial Central Bank Survey states that currency pairs involving the US dollar account for 88.4% of all currency trading. Additionally, many countries adopt the dollar-peg system, meaning their currencies are tied to the value of the US dollar. According to the 2022 IMF report, 37 countries and regions use the dollar-peg system, accounting for approximately 20% of IMF member states.
