The U.S. Dollar Index is an index of the value of the United States dollar relative to a basket of foreign currencies, often referred to as a basket of U.S. trade partners’ currencies. The Index goes up when the U.S. dollar gains “strength” when compared to other currencies. Wikipedia
The dollar index tracks the relative value of the U.S. dollar against a basket of important world currencies. If the index is rising, it means that the dollar is strengthening against the basket – and vice-versa.
The USDX tracks the dollar’s (USD) relative strength against a basket of foreign currencies. The weightings have been fixed since 1973 (and later adjusted in 2002 when the euro replaced many European currencies):
- Euro (EUR) – 57.6% weight
- Japanese yen (JPY) – 13.6%
- Pound sterling (GBP) – 11.9%
- Canadian dollar (CAD) – 9.1%
- Swedish krona (SEK) – 4.2%
- Swiss franc (CHF) – 3.6%
