Unlocking the Secrets of the US Dollar Index (USDX)


Understanding indices is crucial in financial markets. Technically, an index assesses the price performance of a basket of financial instruments leveraging a methodology and metrics. So, an index is a comprehensive measure of the performance of an asset class.


The US Dollar Index is among the most followed indices. It is calculated against a geometrically weighted average of six significant currencies, including:


  • Euro (EUR)
  • Japanese Yen (JPY)
  • British Pound Sterling (GBP)
  • Canadian Dollar (CAD)
  • Swedish Krona (SEK)
  • Swiss Franc (CHF)


The weightage of these currencies and the formula to calculate the USDX were set while establishing the US Dollar Index in 1973. The weightage was reviewed in 1999 while incorporating the Euro in this index.


The Significant Uses

The USDX is among the most followed indices, as it is used for various purposes, such as:

  • Gauging the strength or weakness of the US Dollar against the other currencies in the basket.
  • Assessing the US Dollar purchasing power for international trade.
  • Central banks monitor the USDX to examine the impact of the US Dollar on their currencies.
  • Investors and companies use the USDX as a hedging tool to mitigate currency risks.


The Federal Reserve System required a benchmark to assess the US Dollar's strength against other major Forex currencies. So, the US Dollar Index was established in 1973.
