The KOF Economic Barometer is a composite leading indicator for the Swiss economy. Monthly from 1991.
Since the 1970s, the KOF Swiss Economic Institute has published a leading composite indicator, the KOF Economic Barometer, predicting how the Swiss economy should perform in the near future. The methodology was overhauled in 1998, 2006 and 2014.
As of 2019, it is synthesized from over 345 indicator variables selected from a pool of more than 600 candidates. Every year the source may choose to change the composition and weighting of the index. The chosen variables best meet these two criteria: They (a) have an economically plausible influence and (b) have a certain lead time of a relevant strength over the economic trend.
KOF updates the set of underlying indicators and their weights annually after the release of previous year’s annual Gross Domestic Product (GDP) data by the Swiss Federal Statistical Office (FSO).
The reference series is the smoothed continuous growth rate of Swiss GDP distributed across the three months of a quarter, based on the official quarterly real GDP statistics, adjusted for the effects of major international sporting events, released by the Swiss State Secretariat for Economic Affairs (SECO) in early September.
Each year in the autumn, after release of Swiss GDP, the source produces a new vintage of the Barometer. New components are selected, the base period is advanced by one year, and the full history is revised.
Usually the base period is advanced each year, and KOF's "vintage" name is one year after the last year in the base period. However, Vintages 2020 and 2021 use the same base period (viz., 2010m1 to 2019m12) because of the COVID-19 global pandemic.
