DXYThe U.S. Dollar Index (DXY) is a measure of the value of the United States dollar relative to a basket of six foreign currencies: the euro (EUR), Japanese yen (JPY), British pound (GBP), Canadian dollar (CAD), Swedish krona (SEK), and Swiss franc (CHF). The index was introduced in 1973 by the U.S. Federal Reserve following the dissolution of the Bretton Woods Agreement and the transition to floating exchange rates.
The DXY is calculated by taking a weighted geometric mean of the dollar's value compared to these currencies, with the euro having the largest weighting at approximately 57.6%
