“The BIS effective exchange rate (EER) indices now 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 2008-10 and the indices’ base year is 2010. Two basket compositions are available:
- Broad indices comprising 61 economies, with data from 1994 (CSV, 172 kb or Excel, 247 kb)
- Narrow indices comprising 27 economies, with data from 1964 (CSV, 198 kb or Excel, 308 kb)
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, and the most recent weights are based on trade in 2008-10 (see broad and narrow weights). The EER indices are available as monthly averages. For an explanation of the methodology behind the BIS EER indices, see:
- The new BIS effective exchange rate indices, BIS Quarterly Review, March 2006
- Measuring international price and cost competitiveness, BIS Economic Papers, no 39, November 1993
The monthly effective exchange rate data will be released mid-month on a monthly basis.”
