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
- In a given calendar week, the WEA index stands at 1.0. This means that in that week, the weekly economic activity is 1.0% higher than in the same week of the previous year.
- The WEA index averages 2.0 in a specific quarter. This implies a 2.0% year-on-year growth in real GDP adjusted for seasonal, calendar and sport event effects.

Notes
- The time series of the WWA index from 2005 onward was fully revised on 1 October 2025, as the index was scaled to the revised GDP data. Further information on the comprehensive 2025 benchmark revision of the GDP data can be found at www.seco.admin.ch/gdp.
- 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.
