dxyThe U.S. Dollar Index (DXY) is a measure of the U.S. dollar's value against a weighted basket of six major foreign currencies. The euro has the largest weight at 57.6%, followed by the Japanese yen (13.6%), British pound (11.9%), Canadian dollar (9.1%), Swedish krona (4.2%), and Swiss franc (3.6%). Created in 1973 after the Bretton Woods system's collapse, the DXY helps traders and investors track the dollar's overall strength in international markets. When the index rises, it means the dollar is strengthening against these currencies, while a falling DXY indicates dollar weakness. Many factors influence the DXY, including U.S. monetary policy, interest rates, economic indicators, and global market sentiment.
