The table entitled “Overall trade weights used in the calculation of the effective exchange rates (EER) of the euro“
on page 49 shows trading partners’ membership of the
extended or the broad EER group as well as their percentage weights. To prevent breaks in the time series, the indices of two consecutive weighting periods are chain-linked
beyond the end of the preceding period. See the ECB’s
website for information on the revised trade weights published from July 2020 (https://www.ecb.europa.eu/stats/
pdf/exchange/updatedtradeweights201708202007.pdf?
f184ad85cc2c5ccefd05680706893cde).
The real effective exchange rates of the euro additionally
take account of the differences in price movements between the groups of countries under review. If the current
price indices for determining the real effective exchange
rate based on consumer price indices are not yet available,
estimates are used for the calculation.
For further information on the calculation method, see the
ECB’s methodological notes relating to the daily nominal
effective exchange rate of the euro and ECB Occasional
