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 10 August 2020

  • For the week of 3 - 9 August (week 32) the WAI stands at 0.9. Thereby it indicates an increase compared to roughly stagnation a week earlier (previously -0.0).
  • The index value indicates that trend-adjusted economic activity (measured by the WAI) in the 13 weeks up to 9 August was 0.9 % above activity in the preceding 13 weeks.
  • The WAI-implied GDP growth rate for the last 13 weeks up to 9 August compared with the preceding 13 weeks was 1.8 %.

Note that data for week 32 was missing for the indicator ‘air pollution’ during the update. 

The next update is scheduled for 17 August 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.
