Definition of U.S. Dollar Index (USDX)
The U.S. Dollar Index (USDX) is a financial index that measures the value of the U.S. dollar (USD) relative to a weighted basket of six major foreign currencies, providing a benchmark for the dollar’s strength or weakness in global markets. This currency basket includes the Euro (EUR), Swiss Franc (CHF), Japanese Yen (JPY), Canadian Dollar (CAD), British Pound (GBP), and Swedish Krona (SEK). Established in 1973 with a base value of 100, the USDX serves as a key indicator for investors and policymakers alike—reasonably reflecting how well the dollar performs against these currencies. One might argue it’s like a popularity contest, but in foreign exchange, popularity could mean economic stability!
