The U.S. Dollar Index, a measure of the value of the United States dollar relative to a basket of six major foreign currencies: the euro, Japanese yen, British pound, Canadian dollar, Swedish krona, and Swiss franc. The euro carries the heaviest weighting at 57.6% of the basket. The USDX is widely used by traders, analysts, and central banks as a benchmark for overall dollar strength and is traded as a futures contract on the Intercontinental Exchange (ICE).
Example
“The USDX dropped below 100 for the first time in a year after dovish Fed commentary, signalling broad-based dollar weakness against its major trading partners.”
