The BIS calculates effective exchange rate (EER) indices for a total of 52 economies (including individual euro area countries and, separately, the euro area as an entity). 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.
Two basket compositions are available:
The weighting pattern is time-varying, and the most recent weights are based on trade in 2002–04 (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:
