Chicago Fed National Activity Index (CFNAI)

What Is CFNAI?

The Chicago Fed National Activity Index (CFNAI) is a monthly composite of 85 economic indicators across four categories: production and income, employment-related, personal consumption and housing, and sales, orders, and inventories. The Federal Reserve Bank of Chicago aggregates these into a single weighted composite.

The index is scaled so that zero indicates trend-level economic growth (approximately 2-2.5% real GDP growth per year). Positive values indicate above-trend growth; negative values indicate below-trend growth. A 3-month moving average (CFNAI-MA3) smooths the noise.

Why It Matters for Markets

CFNAI is the most comprehensive single-number business-cycle indicator available. It is one of the primary inputs to NBER recession-dating analysis and is widely used in academic and Fed business-cycle research. The combination of 85 indicators makes it more reliable than any single series.

For markets, CFNAI is a tier-2 macro release because most of its components have already been released individually. The release primarily serves as a synthesis of the month's data rather than new information. The Fed and forecasters use it for cross-checking individual indicator readings against the broader business-cycle context.

How to Read the Print

Three-month moving average. The cleanest single read. The Chicago Fed considers values above 0.7 to indicate sustained above-trend growth, values below -0.7 to indicate recession-consistent activity.

Four-category breakdown. The Chicago Fed publishes the four sub-components separately. Discrepancies between categories reveal dynamics: production strong but employment weak signals manufacturing-led but jobless growth; consumption strong but production weak signals services-led growth, etc.

Diffusion sub-index. The Chicago Fed also publishes a CFNAI Diffusion Index measuring the breadth of monthly changes. A high diffusion index alongside a positive CFNAI signals broadly-based expansion; low diffusion alongside positive CFNAI signals narrow expansion driven by a few categories.

Historical Context

CFNAI data go back to 1967. The 2010-2019 average was approximately 0.0 (trend growth). The 2008-2009 recession produced 3-month averages below -3.0. The pandemic shock briefly produced averages below -4.0 (April 2020 was -8.5, the lowest in the data series).

Through 2024-2025, the 3-month moving average has run in the -0.4 to +0.2 range, indicating moderate-to-trend-level growth. The production-and-income sub-component has been weakest (consistent with the manufacturing weakness throughout the cycle); the consumption sub-component has been most resilient. The composite has not approached the -0.7 recession-warning level despite the manufacturing-sector slowdown.
