Weekly activity index for the German economy

The weekly activity index (WAI) is an index designed to measure real economic activity in Germany in a timely manner. The index is based on daily, weekly, monthly and quarterly indicators for the German economy.

Weekly activity index and GDP growth

Update as of 19 October 2020

  • For the week of 12 – 18 October (week 42) the WAI stands at 2.8. The increase is thus lower than that in the preceding week (previously 3.2).
  • The index value indicates that trend-adjusted economic activity (measured by the WAI) in the 13 weeks up to 18 October was 2.8 % above activity in the preceding 13 weeks.
  • The WAI-implied GDP growth rate for the last 13 weeks up to 18 October compared with the preceding 13 weeks is 5.0 %.

As of 19 October 2020 the Federal Office for Goods Transport, the data provider for the indicator toll (daily truck toll mileage index), stopped delivering the data on a daily basis. Instead, as of 22 October they are provided on a weekly basis on Thursdays. Thus, there will be no data available for the indicator toll for the most recent week in future. For the indicator electricity, data is missing for 17 – 18 October. Computation of the WAI is based on published values only.

The next update is scheduled for 26 October 2020.


The WAI is still a work in progress; it is constantly undergoing revision and, when necessary, adjusted (see Methodology). The WAI is not an official forecast of the Deutsche Bundesbank or the Eurosystem.
