BIS effective exchange rate indices

updated 15 September 2014

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 or Excel)
  • Narrow indices comprising 27 economies, with data from 1964 (CSV or Excel)

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 monthly effective exchange rate data will be released mid-month on a monthly basis.
