Benchmarks must keep pace with their changing environment. The Bloomberg Dollar Spot Index offers a real time measure of the greenback against a diversified, dynamic basket of emerging and developed market currencies.


The Bloomberg Dollar Spot Index (BBDXY) tracks the performance of a basket of 10 leading global currencies versus the U.S. Dollar. Through its dynamically updated composition of diversified currencies that are important from trade and liquidity perspectives, it provides a better measure of the U.S. Dollar compared to indexes that do not update their composition and are comprised of a handful of currencies with concentrated weights.

The index rebalances annually to capture annual trading flows versus the U.S. dollar as reported by the Federal Reserve and the triennial survey of most liquid currencies from the Bank of International Settlements. Each currency in the basket and their weight is determined annually based on their share of international trade and FX liquidity. The BBDXY Index data starts from Dec 31, 2004 with a base level of 1000.

Bloomberg users can run BDXY <GO> on the Bloomberg Professional service to view the Bloomberg Dollar Spot Index.

2015 target weights are effective end of business day, December 31, 2014.
