We’ve talked about the U.S. Dollar Index (USDX) and the Trade-Weighted Dollar Index, but traders who want a spot index price on the U.S. Dollar can also turn to the Bloomberg dollar spot index (BBDXY) for help. It tracks the performance of a basket of 10 foreign currencies against the U.S. Dollar.

The composition of this index is updated yearly to reflect a diverse set of currencies to compare against the USD.

The Bloomberg dollar spot index may be a better option in some cases than the widely acclaimed DXY because they update the composition of their index yearly. Bloomberg insists that this makes their index more useful to a broad range of traders.

Every currency included in the BBDXY is weighed based on its levels of international trade and FX liquidity for the year. Below you’ll find the 2021 weights:
