As the chart comparing the two shows, the difference isn't very pronounced though the Atlanta Trade Weighted Index fell more than the broad index. However, one thing is perfectly evident: both fell SHARPLY in past few years! The differences between the two indexex in short is as follows:frbatlanta.org "The Atlanta Fed index is based on 1995–97 bilateral trade weights for 15 currencies. The European subindex includes the European Monetary Union, Switzerland and the United Kingdom. The Pacific subindex includes Australia, China, Hong Kong, Japan, Malaysia, Singapore, South Korea and Taiwan. The Americas subindex includes Brazil, Canada and Mexico. The overall dollar index includes the Saudi Arabian riyal along with the foregoing 14 currencies." Whereas the broad index is much more representative of current U.S. trading patterns as the weights are adjusted yearly.federalreserve.gov "...To capture the evolving nature of international trade patterns, the staff’s current exchange rate indexes allow changes in the component exchange rates and their weights. The currency weights in the dollar indexes are based on annual trade data, vary by year, and have been updated annually since 1998. Although the set of exchange rates in the indexes has remained unchanged so far, the staff will continue to review whether changes in composition or methodology are needed to ensure that the indexes adequately reflect ongoing developments in international trade patterns. ... The Broad Index The currencies chosen for inclusion in the broad dollar index in 1998 were determined pragmatically as those of economies whose bilateral shares of U.S. imports or exports exceeded 1/2 percent in 1997, the latest year for which complete annual trade data were then available. On the basis of this criterion, the staff selected twenty-six currencies. Anticipating the adoption of the euro at the end of 1998 by eleven member countries of the European Union (EU), the staff designed the index so that a single weight for the euro could capture the influence of the dollar–euro exchange rate on trade competition between the United States and the euro area. ..."
