Trade-Weighted U.S. Dollar Index

There is also another kind of dollar index used by the Federal Reserve. It is called the “trade-weighted U.S. dollar index”.

The Fed wanted to create an index that could more accurately reflect the dollar’s value against foreign currencies based on how competitive U.S. goods are compared against other countries.

The main difference between the USDX and the trade-weighted dollar index is the basket of currencies used and their relative weights. The weights are based on annual trade data.
