The Conference Board publishes leading, coincident, and lagging indexes designed to signal peaks and troughs in the business cycle for major economies around the world.
The Conference Board Leading Economic Index® (LEI) for the US Declined in September
Latest Press Release
Updated: Monday, October 21, 2024
Using the Composite Indexes: The Leading Economic Index (LEI) provides an early indication of significant turning points in the business cycle and where the economy is heading in the near term. The Coincident Economic Index (CEI) provides an indication of the current state of the economy. Additional details are below.
The Conference Board Leading Economic Index® (LEI) for the US declined by 0.5% in September 2024 to 99.7 (2016=100), following a 0.3% decline in August. Over the six-month period between March and September 2024, the LEI fell by 2.6%, more than its 2.2% decline over the previous six-month period (September 2023 to March 2024).
“Weakness in factory new orders continued to be a major drag on the US LEI in September as the global manufacturing slump persists,” said Justyna Zabinska-La Monica, Senior Manager, Business Cycle Indicators, at The Conference Board. “Additionally, the yield curve remained inverted, building permits declined, and consumers’ outlook for future business conditions was tepid. Gains among other LEI components were not significant enough to offset weakness among the four gauges mentioned above. Overall, the LEI continued to signal uncertainty for economic activity ahead and is consistent with The Conference Board expectation for moderate growth at the close of 2024 and into early 2025.“
The Conference Board Coincident Economic Index® (CEI) for the US inched up by 0.1% in September 2024 to 112.9 (2016=100), after a downwardly revised 0.2% increase in August. The CEI increased by 0.9% in the six-month period ending September 2024, higher than its 0.5% growth rate over the previous six-month period. The CEI’s component indicators—payroll employment, personal income less transfer payments, manufacturing and trade sales, and industrial production—are included among the data used to determine recessions in the US. Payroll employment, personal income less transfer payments, and manufacturing and trade sales contributed positively to the index in September and slightly more than offset a decline in industrial production.
The Conference Board Lagging Economic Index® (LAG) for the US declined by 0.3% to 118.9 (2016=100) in September 2024, after no change in August. The LAG’s six-month growth rate turned negative, showing a 0.2% contraction over the six-month period ending in September 2024, after a 1.1% increase over the six-month period from March 2023 to September 2024.
The LEI continued to decline in September
LEI weakness in September continued to be led by new orders and the yield spread
NOTE: Starting with the September 2023 release, Leading Credit Index™ calculations (from 2020 to current) use the SOFR Overnight Financing Rate in the USD Swap spread semiannual 2 year instead of LIBOR rate. LIBOR remains in the USD Swap spread semiannual 2 year from 1990 to 2020.
The US LEI signaled recession again in September, but the economy may only slow ahead
NOTE: The chart illustrates the so-called 3Ds—duration, depth, and diffusion—for interpreting a downward movement in the LEI. Duration refers to how long the decline has lasted. Depth denotes the size of decline. Duration and depth are measured by the rate of change of the index over the most recent six months. Diffusion is a measure of how widespread the decline is among the LEI’s component indicators—on a scale of 0 to 100, a diffusion index reading below 50 indicates most components are weakening.
The 3Ds rule signals an impending recession when: 1) the six-month diffusion index lies below 50, shown by the black warning signal lines in the chart; and 2) the LEI’s six-month rate of decline falls below the threshold of −4.4%. The red recession signal lines indicate months when both criteria are met simultaneously—and thus that a recession is likely imminent or underway.
Summary Table of Composite Economic Indexes
About The Conference Board Leading Economic Index® (LEI) and Coincident Economic Index® (CEI) for the US
The composite economic indexes are key elements in an analytic system designed to signal peaks and troughs in the business cycle. Comprised of multiple independent indicators, the indexes are constructed to summarize and reveal common turning points in the economy in a clearer and more convincing manner than any individual component.
The CEI reflects current economic conditions and is highly correlated with real GDP. The LEI is a predictive tool that anticipates—or “leads”—turning points in the business cycle by around seven months.
The ten components of the Leading Economic Index® for the US are:
- Average weekly hours in manufacturing
- Average weekly initial claims for unemployment insurance
- Manufacturers’ new orders for consumer goods and materials
- ISM® Index of New Orders
- Manufacturers’ new orders for nondefense capital goods excluding aircraft orders
- Building permits for new private housing units
- S&P 500® Index of Stock Prices
- Leading Credit Index™
- Interest rate spread (10-year Treasury bonds less federal funds rate)
- Average consumer expectations for business conditions
The four components of the Coincident Economic Index® for the US are:
- Payroll employment
- Personal income less transfer payments
- Manufacturing and trade sales
- Industrial production
