Trade weighted US dollar index

The trade-weighted US dollar index, also known as the broad index, is a measure of the value of the United States dollar relative to other world currencies. It is a trade weighted index that improves on the older U.S. Dollar Index by using more currencies and the updating the weights yearly (rather than never). The base index value is 100 in Jan 1997.[1]


The trade-weighted dollar index was introduced in 1998 for two primary reasons. The first was the introduction of the euro, which eliminated several of the currencies in the standard dollar index; the second was to keep pace with new developments in US trade.[2]

Included currencies

In the older U.S. Dollar Index, a significant weight is given to the euro, because most U. S. Trade in 1973 was with European countries. As U. S. trade expanded over time, the weights in that index went unchanged and became out of date. To more accurately reflect the strength of the dollar relative to other world currencies, the Federal Reserve created the trade-weighted US dollar index,[3] which includes a bigger collection of currencies than the US dollar index. The regions included are:

·         Europe (euro countries)

·         Canada

·         Japan

·         Mexico

·         China

·         United Kingdom

·         Taiwan

·         Korea

·         Singapore
