U.S. Dollar Index

The U.S. Dollar Index measures the value of the United States dollar relative to a basket of six foreign currencies, rising when the dollar strengthens against them and falling when it weakens. It was launched in March 1973, shortly after the collapse of the Bretton Woods system, with a starting value of 100.000. The basket weights the euro at 57.6 percent, the Japanese yen at 13.6 percent, the pound sterling at 11.9 percent, the Canadian dollar at 9.1 percent, the Swedish krona at 4.2 percent, and the Swiss franc at 3.6 percent, combined through a weighted geometric mean of the underlying exchange rates. The index is designed, maintained, and published by ICE, the Intercontinental Exchange, as a registered trademark.
