Effective on February 4, 2019, the Federal Reserve Board staff will make major changes to the methodology used to construct the trade-weighted dollar indexes in the H.10, G.5, and G.5A releases. These changes will affect the calculation of index weights and country composition. The new dollar indexes will go back to (and be indexed to) January 2006.
