The U.S. Dollar Index tracks the strength of the dollar against a basket of major currencies. (
DXY) originally was developed by the U.S. Federal Reserve in 1973 to provide an external bilateral trade-weighted average value of the U.S. dollar against global currencies. U.S. Dollar Index goes up when the U.S. dollar gains "strength" (value), compared to other currencies. The following six currencies are used to calculate the index:
Euro (EUR) 57.6% weight
Japanese yen (JPY) 13.6% weight
Pound sterling (GBP) 11.9% weight
Canadian dollar (CAD) 9.1% weight
Swedish krona (SEK) 4.2% weight
Swiss franc (CHF) 3.6% weight
