Starting with a base value of 100, the USDX offers a quantifiable measure of the U.S. dollar's strength or weakness on the international stage. It serves as a macroeconomic benchmark, reflecting the impact of political, economic, and market events on the dollar's value.

The basket of currency includes the Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona, and Swiss Franc. The Euro has the highest weight, significantly influencing the index's movement. The selection and weighting of these currencies are based on the U.S.'s trade balance with the respective countries, providing a comprehensive overview of the dollar’s performance against its most significant trading partners.

Originally introduced in 1973 by the New York Board of Trade (NYBOT), the index provides a benchmark to gauge the dollar's overall strength or weakness in the global foreign exchange market.

In the future, there are predictions that the index might see changes. It is possible that currencies like the Chinese yuan (CNY) and Mexican peso (MXN) will replace other currencies in the index due to the fact that China and Mexico are significant trading partners of the U.S.
