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, after release of GDP, the source produces a new vintage of the Barometer. After redefining its components, the Barometer is recomputed and full revised history is published. The base period is advanced by one year.
