The ZEW Indicator of Economic Sentiment is a crucial metric for assessing the economic outlook of Germany. Developed from the monthly ZEW Financial Market Survey, this indicator aggregates the perceptions of approximately 350 economists and analysts about the country's economic prospects over the medium term. The abbreviation ZEW stands for Zentrum für Europäische Wirtschaftsforschung, or the Center for European Economic Research, which is responsible for compiling and disseminating the survey data.
Key Insights
-
Definition and Purpose: The ZEW Indicator serves to measure expert opinions regarding the direction of the German economy over the next six months. It provides valuable insights that can indicate overall economic sentiment.
-
Data Collection Methodology: The indicator is derived from a monthly survey of analysts and financial professionals, focusing primarily on their expectations for the German economy. It responds to evolving market conditions and speculations about future trends.
-
Sentiment Landscape: If the indicator yields a positive reading, this suggests a bullish sentiment among experts, while a negative reading indicates a bearish outlook.
The Mechanism Behind the ZEW Indicator
The construction of the ZEW Indicator is straightforward. Researchers measure the difference between the percentage of economists who are optimistic about the German economy and those who are pessimistic. For instance, if 50% of respondents feel the economy will improve, while 20% predict a decline, the reading would indicate a strong positive sentiment.
In historical context, the indicator can exhibit considerable volatility, reflecting rapid shifts in economic conditions. For example, in 2018, the ZEW Indicator fluctuated dramatically, showcasing a shift from a bullish sentiment of +20.4 to a bearish stance of -25 over just seven months, even as German economic growth slowed from 2.2% in 2017 to 1.5% in 2018. This case underlines the tendency of sentiment indicators to sometimes exaggerate economic trends, illustrating the nuances of interpreting such metrics.
The Role of Sentiment Indicators

Wisdom of Crowds
One core principle in utilizing sentiment indicators is the "wisdom of crowds." This concept suggests that while individual opinions may vary widely, aggregating the insights of a large, diverse group often leads to more accurate market predictions. By capturing the collective sentiment of various experts, the ZEW Indicator provides a more reliable perception of economic health.
Data Composition

The survey encompasses various aspects of economic activity, including inflation rates, interest rates, stock market trends, exchange rates, and fluctuations in oil prices.
Besides focusing on the German economy, the survey also extends to the economic outlook of several other key regions, such as:
- The United States
- The eurozone

- Italy
This comparative analysis enables a comprehensive understanding of global economic interactions and potential impacts on German economic sentiment.
