The index of weekly economic activity (WEA) provides immediate information about the growth of the Swiss economy. It does not replace the GDP calculations, but it shows a high correlation with the growth of real GDP in Switzerland and supplements the existing data. The calculation covers the period from 2005 and is based on daily and weekly indicators.
Weekly economic activity

Reading example
- For calendar week 37 2022, the WEA index stood at 1,6. This means that in this week, the weekly economic activity was 1.6% higher than in the same week of the previous year.
- The WEA index averaged 1.9 in Q2 2022, which implies a 1.9% year-on-year growth in real, seasonally, calendar and sport event adjusted GDP.
machine-readable data
Notes
- The WEA index is an experimental statistic, is constantly checked and can be amended if necessary.
- The WEA index is neither a weekly GDP figure nor a forecast of GDP by SECO or by the Federal Government’s Expert Group on Economic Forecasts.
- The WEA index may be revised retrospectively if the indicators it consists of are revised.
- Due to the extraordinary partial revision of the national accounts in summer 2022, the calculation of the WEA index has been updated. This results in revisions for the entire series from 2005.
