The U.S. dollar index is a measure of the value of the U.S. dollar relative to the value of a basket of currencies. Currently, this index is calculated by factoring in the exchange rates of six major world currencies the Euro, Japanese Yen, Canadian Dollar, British Pound, Swedish Krona and the Swiss Franc. The Euro holds the most weight versus the dollar in the DXY index, constituting 57.6% of the weighting followed by the Japanese Yen with 13.6%, the British Pound is weighted at 11.9% and the Canadian dollar with 9.1%. The index started in 1973 with a base of 100, and values since then are relative to this base. The U.S Dollar index price is traded as a CFD on Sandton Capital Market trading platforms.
