The US Dollar Index (DXY or USDX) is a leading financial benchmark that measures the value of the United States dollar relative to a weighted basket of six major global currencies. Often referred to by its ticker symbol, DXY (or informally, “the Dixie”), it serves as a critical macroeconomic health check for international trade, commodity pricing, and global investment flows. The Currency Basket: How the Index is Made
The DXY does not compare the dollar to every currency in the world. Instead, its price is calculated using a weighted geometric mean of six currencies representing major US trading partners. Index Weight (%) Euro Japanese Yen British Pound Canadian Dollar Swedish Krona Swiss Franc
Because the Euro holds a massive 57.6% share of the basket, the DXY is heavily influenced by economic conditions in the Eurozone. If the Euro weakens significantly, the DXY will almost always push higher, even if the dollar stays flat against other currencies. Reading the Numbers: The Base 100 Baseline
The index was established by the US Federal Reserve in 1973 right after the Bretton Woods system collapsed and global currencies began to float freely against each other.
The DXY started with a base value of 100.00. Interpreting its current value is straightforward: Understanding the U.S. Dollar Index (USDX) and Trading Tips
