Bank of International Settlements - Effective Exchange Rate Indices

Effective exchange rate indices


Updated 16 March 2016

November 2015: The BIS has revised and updated the weights used in the effective exchange rates (EER) so that the most recent weights refer to 2011-13 period. In addition, Latvia and Lithuania are now included in the euro area aggregate and the real EER for India is now using consumer price index instead of the wholesale price index for the recent periods. New sources have been used for some historical data on exchange rates and consumer prices.

The BIS effective exchange rate (EER) indices cover 61 economies, including individual euro area countries and, separately, the euro area as an entity. The most recent weights are based on trade in the 2011-13 period, with 2010 as the indices' base year.

Nominal EERs are calculated as geometric weighted averages of bilateral exchange rates. Real EERs are the same weighted averages of bilateral exchange rates adjusted by relative consumer prices. The weighting pattern is time-varying (see broad and narrow weights). The EER indices are available as monthly averages. An increase in the index indicates an appreciation.
