Datta1  \nStarting in February 2019, the Federal Reserve will make important changes to the foreign exchange rate indexes included in the H.10, G.5, and G.5A releases. The changes include revisions to the weighting scheme and country composition. This note details the construction of the indexes and describes the motives for the changes to the methodology. 2  \nI. Index construction  \nThe Federal Reserve dollar indexes are designed to help estimate the overall effects of U.S. dollar exchange rate movements [on U.S. international](on U.S. international) trade. There are three indexes: the broad dollar index, which is constructed using the currencies of the most [important U.S. trading](important U.S. trading)[ ](important U.S. trading)[partners by volume of bilateral trade](partners by volume of bilateral trade), and two sub-indexes, which split the currencies in the broad index into advanced foreign economies (AFE) and emerging market economies (EME) .3 This section describes the methodology for constructing these indexes that goes into effect starting in February 2019; the next section describes how this methodology differs from the prior approach; section 3 describes how these changes are implemented; and section 4 examines the effects of these changes.  \nThe broad dollar index contains the currencies of 26 economies for which bilateral trade with the United States accounts for at least 0.5 percent of total U.S. bilateral trade. These economies are listed in Table 1. The AFE dollar index contains seven currencies, and the EME dollar index contains the remaining 19 currencies.  \nConsistent with market practice, daily changes in the indexes are computed using geometricallyweighted averages of changes in bilateral exchange rates. The index at time t (􀜫􀯧) is:  \n􀜫􀯧 = 􀜫􀯧−1 ∗ ∏􀯇􀯝=(􀯧1) (􀝁􀯝 , 􀯧⁄􀝁􀯝, 􀯧−1)􀯪 􀳕, 􀳟 , (1)  \nwhere 􀀳 represents the product operator, 􀜫􀯧−1 is the value of the index at time t-1; 􀝁􀯝 , 􀯧 and 􀝁􀯝, 􀯧−1 are the prices ofthe U.S. dollar in terms of foreign currency j at times t and t-1; 􀝓􀯝 , 􀯧 is the weight of currency j in the index at time t; N(t) is the number of foreign currencies in the index at time t; and the weights sum to one (∑􀯝 􀝓􀯝 , 􀯧 = 1) .  \nThe weights are computed using annual bilateral trade data published by the Bureau of Economic Analysis (BEA) . For each economy j, the weight at time t is:  \n1 We thank Daliah R. Al-Shakhshir, Vickie L. Chang, and Samantha A.
