Introduction
The Leading Economic Index (LEI) is a composite index designed to predict future economic activity. It is formulated by combining various individual economic indicators that historically have shown the ability to forecast turning points in the economy. LEI is highly valuable to economists, policymakers, and investors for its predictive capabilities.
Historical Context
The concept of aggregating multiple indicators to predict economic activity dates back to the early 20th century. However, the LEI as it is known today was developed in the late 1960s by the Conference Board, a non-profit organization. This index has since become a critical tool for understanding economic trends and making informed decisions.
Types/Categories of LEI Indicators
- Labor Market Indicators: Includes average weekly hours in manufacturing and initial claims for unemployment insurance.
- Production Indicators: Encompasses indexes like manufacturers’ new orders for consumer goods and materials.
- Financial Indicators: Includes components such as the S&P 500 stock index and the Leading Credit Index.
- Consumer Expectations: Includes the University of Michigan’s Index of Consumer Sentiment.
- Housing Market Indicators: For instance, building permits for new private housing units.
Key Events
- 1968: The Conference Board began publication of the LEI.
- 1989: The LEI methodology was revised to improve predictive accuracy.
- 2001-2008: The LEI successfully signaled economic slowdowns and recoveries, showcasing its reliability.
Detailed Explanation
LEI is composed of ten key indicators which are weighted based on their historical ability to predict the business cycle. The formula for LEI can be represented as:
where \(X_i\) represents the individual indicator values and \(w_i\) represents the weight assigned to each indicator.

Importance and Applicability
The LEI is crucial because it provides a forward-looking perspective on the economy, unlike lagging indicators that confirm trends only after they happen. Policymakers utilize LEI to implement preemptive measures, while investors use it to strategize portfolios based on anticipated economic conditions.
Examples
- Anticipating Recessions: A consistent decline in the LEI over several months typically signals an upcoming recession.
- Investment Decisions: Investors might reallocate assets to safer investments if the LEI suggests an economic downturn.
Considerations
- Data Timeliness: Some components of the LEI are subject to revision, affecting its predictive reliability.
- Weighting Methodology: The weighting of indicators may require periodic adjustment to reflect changing economic dynamics.
Related Terms
- Business Cycle Indicators (BCI): A group of statistical measures that reflect the current state of the economy.
- Coincident Economic Index (CEI): Measures current economic activity.
- Lagging Economic Index (LAG): Follows economic trends and confirms patterns.
Comparisons
- LEI vs. CEI: LEI predicts future economic activities, whereas CEI provides a snapshot of the current state of the economy.
- LEI vs. LAG: LEI is forward-looking, whereas LAG is backward-looking.
