Dollar Index (DXY) the barometer for global currencies
The U.S. Dollar Index (USDX, DXY, DX, or, informally, the "Dixie") is an index (or measure) 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 is designed, maintained, and published by ICE (Intercontinental Exchange, Inc.), with the name "U.S. Dollar Index" a registered trademark.
It is a weighted geometric mean of the dollar's value relative to following select currencies:
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
One of the most important barometers for global currencies is the Dollar Index (DXY), which measures the value of the US Dollar versus a basket of global currencies. The basket of currencies essentially consists of nations that have significant trading relationship with the US and are also hard floating currencies.
The Dollar being the central currency for global trade and commerce becomes an important barometer for global economies.
Since the dollar continues to be the predominant currency in world trade, this measure of DXY gives a fairly representative picture of the strength of the dollar.
