Leading economic index: Meaning, Criticisms & Real-World Uses

What Is a Leading Economic Index?

A Leading Economic Index (LEI) is a composite statistical measure used within the field of economic indicators to forecast future economic activity. These indices are specifically designed to change direction before the overall economy, providing insights into upcoming shifts in the business cycles of a country or region. By anticipating trends, leading economic indices serve as crucial tools for economists, policymakers, and investors in developing economic forecasts and preparing for periods of recession or economic expansion.

History and Origin

The concept of economic indicators, particularly those that lead the business cycle, gained prominence in the early 20th century. A significant milestone in the development of the Leading Economic Index was the work done at the National Bureau of Economic Research (NBER), a private, nonprofit research organization. Researchers like Wesley Clair Mitchell and Arthur F. Burns pioneered the systematic study of business cycles and the identification of economic series that consistently precede turns in the economy.¹⁵,

Building on this foundational work, The Conference Board, a non-governmental research organization, took on the responsibility of compiling and publishing a composite Leading Economic Index for the United States. This index was initially developed in the late 1950s by the U.S. Department of Commerce before being taken over by The Conference Board in 1995. The organization continues to calculate and disseminate the LEI, making regular adjustments to its components to maintain its relevance and predictive power for the U.S. and other major global economies. The Conference Board's Leading Economic Index aims to provide an early indication of significant turning points in the business cycle.¹⁴

Key Takeaways

A Leading Economic Index (LEI) is a composite metric designed to predict future economic trends, typically by six to nine months.
The LEI is comprised of multiple individual economic series that tend to turn before the broader economy.
Movements in a leading economic index can signal impending shifts from economic expansion to recession, or vice versa.
While useful for forecasting, these indices are not infallible and can sometimes generate false signals due to various economic and statistical factors.
The most widely recognized LEI is published by The Conference Board.

Formula and Calculation

A Leading Economic Index is a composite index, meaning it is not derived from a single mathematical formula but rather by aggregating several distinct economic data series. The specific components are chosen for their consistent tendency to "lead" or anticipate changes in overall economic activity. Each component is weighted, and the combined movement of these indicators results in the overall index value.

For example, The Conference Board Leading Economic Index for the U.S. includes ten components:

Average weekly hours in manufacturing
Average weekly initial unemployment claims
Manufacturers’ new orders for consumer goods and materials
ISM® Index of New Orders
Manufacturers’ new orders for non-defense capital goods excluding aircraft orders
Building permits for new private housing units
S&P 500® Index of stock market performance
Leading Credit Index™
Interest rates spread (10-year Treasury bonds less federal funds rate)
Average consumer confidence for business conditions,

The p¹³r¹²ocess involves standardizing each component to prevent individual series with larger fluctuations from dominating the index. These standardized components are then weighted, typically based on their historical correlation with the business cycle, and combined to produce the aggregate index.

Interpreting the Leading Economic Index

Interpreting a Leading Economic Index involves analyzing its direction and magnitude of change over time. A sustained decline in the LEI often suggests an impending economic slowdown or recession, while a consistent rise points towards future economic expansion. For instance, The Conference Board notes that a decline in the LEI's six-month growth rate, particularly when accompanied by a low diffusion index (indicating fewer components are rising), can trigger a recession signal.

Analys¹¹ts pay close attention to trends, rather than single-month movements, as individual components can be volatile. For example, a widening yield curve (where long-term rates are significantly higher than short-term rates) is typically seen as a positive sign for future economic growth, whereas an inverted yield curve often precedes a recession. Shifts in market sentiment, as captured by components like consumer expectations or stock prices, also offer valuable insights into the collective outlook of economic participants.

Hypothetical Example

Consider a hypothetical Leading Economic Index for a small, manufacturing-heavy economy. Over the past three months, the index has shown a consistent decline:

Month 1: New manufacturing orders decreased by 5%, and average weekly hours in manufacturing saw a slight reduction. Meanwhile, building permits for new residential units also fell. The LEI reflects a modest dip.
Month 2: The trend continues. Manufacturing orders decline further, and initial unemployment claims show a noticeable increase. Consumer expectations for business conditions become more pessimistic. The LEI registers a sharper drop.
Month 3: Manufacturing orders contract again, and the interest rate spread narrows considerably. The stock market, while volatile, shows a general downward trend over the period. The LEI posts another significant decline, indicating a sustained negative movement.

This sustained decline in the Leading Economic Index over three consecutive months, driven by several key components, would suggest a strong probability of an economic slowdown or even a recession in the coming six to nine months for this hypothetical economy. Businesses might use this signal to adjust production plans, delay investments, or prepare for reduced consumer demand.

Practical Applications

Leading Economic Indices are widely used by various stakeholders for strategic planning and decision-making. Investors often monitor the LEI for clues about the overall direction of the market and the economy, influencing their asset allocation and investment strategies. A declining LEI might prompt a shift towards more defensive assets, while a rising index could encourage investments in growth-oriented sectors.

For businesses, the Leading Economic Index can inform operational decisions, such as inventory management, hiring plans, and capital expenditure. For instance, if the LEI suggests a slowdown, companies might reduce their current inventory levels or postpone significant investments. Conversely, a positive LEI trend could signal an opportune time for expansion. Indicators such as the S&P 500® Index of Stock Prices, a component of the LEI, are closely watched as they often reflect investor expectations about future earnings and economic health.

Policymakers and central banks also utilize the LEI as part of their broader analysis of economic conditions, helping them anticipate challenges and formulate appropriate monetary or fiscal policies. The Federal Reserve Bank of Chicago, for example, has analyzed the effectiveness of various leading indicators in signaling past recessions. Reports ¹⁰from The Conference Board that incorporate the Consumer Confidence Index are regularly cited in economic news and analysis, providing insights into public sentiment about the future economic outlook.

Limi⁹tations and Criticisms

While a Leading Economic Index is a valuable forecasting tool, it is subject to several limitations and criticisms. One significant challenge is the potential for "false signals." The LEI may indicate a recession that does not materialize, or its signals may be delayed or too early to be actionable. The effectiveness of individual indicators can also change over time due to structural economic shifts or policy changes.

Another limitation stems from data revisions and reporting lags. Initial estimates of economic data are often based on incomplete information, and subsequent revisions can significantly alter the picture, potentially leading to misinterpretations of the LEI's signal. Furtherm⁸ore, as a composite index, the LEI's construction involves weighting various components, and the choice of these weights can influence the final index value and its interpretive meaning. Critics ⁷also note that composite indicators, while simplifying complex concepts, might mask important details or trends within specific economic sectors., Despite⁶ ⁵these drawbacks, the Leading Economic Index remains a widely used and respected tool, albeit one that should be considered alongside other economic information and professional judgment. For example, recent analyses have debated whether sharp declines in the LEI indicate an actual impending recession or simply a "false" signal due to unique economic conditions.

Lead⁴ing Economic Index vs. Coincident Economic Index

The distinction between a Leading Economic Index and a Coincident Economic Index lies in their timing relative to the overall business cycle.

A Leading Economic Index aims to predict future economic activity, changing direction before the economy shifts. Its components are selected for their forward-looking nature, such as new orders, building permits, or consumer expectations. The purpose of a leading index is to provide an early warning system for economic turning points.

In contrast, a Coincident Economic Index reflects the current state of the economy, moving simultaneously with overall economic activity. Its components include measures like real personal income less transfer payments, nonfarm payroll employment, industrial production, and manufacturing and trade sales. These in³dicators provide a real-time snapshot of economic conditions. For example, a decline in the Coincident Economic Index would confirm that the economy is already in a downturn, whereas a leading index would have signaled that downturn in advance. Both types of indices are crucial for a comprehensive understanding of the business cycle, with leading indices providing foresight and coincident indices confirming the present reality.

FAQs

What does a rising Leading Economic Index mean?

A rising Leading Economic Index typically suggests that the overall economic activity is expected to expand in the coming months. This could indicate stronger employment, increased production, and higher consumer spending.

How accurate are Leading Economic Indices?

Leading Economic Indices have a track record of signaling economic turning points, but they are not perfectly accurate. They can sometimes produce "false positives," signaling a recession that doesn't occur, or their signals might be delayed. Their reliability can also change over time due to evolving economic structures.

Who publishes the most widely cited Leading Economic Index?

The most widely cited Leading Economic Index is published by The Conference Board, a private, non-profit research organization. They provide LEIs for the U.S. and several other major global economies.

Wha²t are some examples of components within a Leading Economic Index?

Common components include average weekly manufacturing hours, initial unemployment claims, new orders for goods, building permits, stock market performance, and consumer expectations. These elements are chosen because they tend to shift before broader economic measures like Gross Domestic Product (GDP).¹
