Germany’s Data Revamp Disaster: Economists Struggle to Keep Up

Germany’s Data Revamp Disaster: Economists Struggle to Keep Up

Since the beginning of this year, Germany’s statistical office, Destatis, has been undergoing a major overhaul of its

statistical system

. The aim is to modernize and harmonize data collection and reporting processes in line with European Union (EU) regulations. However, the revamp has turned into a

disaster

, leaving many economists and market participants struggling to keep up with the new data releases.

The most significant change involves the

unification of various economic indicators

. For instance, Destatis has introduced a new gross domestic product (GDP) calculation method, which differs from the previous one in terms of accounting for taxes and subsidies. This change resulted in a

surprise 1.2 percentage point downward revision

of Germany’s Q4 2020 GDP, causing a wave of confusion and uncertainty among economists.

Moreover, the new statistical methodology has led to

delays and inconsistencies in data releases

. Some indicators, such as industrial production, have been published with significant revisions or have been delayed by weeks. In some cases, the revisions were substantial, which has made it difficult for economists to analyze trends and make accurate forecasts.

Another challenge arises from the fact that Destatis is providing

less detailed data

in some sectors. For example, instead of releasing sector-level industrial production data monthly, Destatis now only provides aggregated data quarterly. This lack of detail is making it harder for economists and market participants to gain insights into specific industries and sectors.

Furthermore, Destatis’ new reporting format is not user-friendly, which adds to the confusion. Instead of providing data in a clear and easily accessible format, the new releases are difficult to navigate, forcing economists to spend more time deciphering the numbers. This, in turn, is limiting their ability to react quickly to new data and market developments.

The German government has acknowledged the challenges posed by the statistical office’s revamp and is working to address some of the issues. For example, it has promised to expedite the publication of delayed data releases and to provide more detailed information where possible. However, it remains to be seen whether these measures will be enough to restore confidence in Germany’s statistical system among economists and market participants.
