Summary
- The monthly reading fell to -0.20 in March from an upwardly revised +0.03 in February.
- The three-month average slipped from +0.03 to -0.03.
- Despite the slip in March, the index points to near-trend economic growth and is well above recession territory.
The National Activity Index published by the Federal Reserve Bank of Chicago (CFNAI) slipped to -0.20 in March from an upwardly revised +0.03 in February (previously (-0.11). This is the lowest monthly reading since last November. Smoothing out the monthly volatility, the index's three-month moving average (CFNAI-MA3) declined to -0.03 in March from an upwardly revised +0.03 in February (previously -0.01).
This index is expressed in standard deviation units from zero (with a value of zero defined as trend real GDP growth). Research at the FRB Chicago indicates that readings on the 3-month average of -0.70 or below are consistent with the economy being in a recession. Therefore, even though the March reading on the 3-month average was negative, it indicates that the US economy is still growing, just slightly slower than trend, and is well away from recessionary conditions. The 3-month average would be much deeper in negative territory if the economy was at risk of contracting.
The National Activity Index is a composite of 85 economic indicators, grouped into four major categories: production and income; employment, unemployment, and hours worked; personal consumption and housing; sales, orders, and inventories. Three of the four broad categories of indicators used to construct the index decreased from February, and three categories made negative contributions in March. Production-related indicators contributed –0.20 to the CFNAI in March, down from +0.13 in February. The sales, orders, and inventories category's contribution to the CFNAI was –0.01 in March, down from +0.05 in February. Employment-related indicators contributed +0.02 to the CFNAI in March, up from –0.15 in February. The personal consumption and housing category's contribution to the CFNAI was –0.01 in March, down from a neutral value in February.
The CFNAI Diffusion Index, which measures the breadth of the change in the component series and is also a three-month moving average, increased to –0.04 in March from –0.08 in February. This is the highest reading since February 2025. A reading of zero indicates that all of the indicators are growing at their long-term average. If all of the underlying indicators in a given month are below their long-run averages, the diffusion index will equal -1. If all of the indicators are above their long-run averages, it will equal +1. Thirty-four of the 85 individual indicators made positive contributions to the CFNAI in March, while 51 made negative contributions. Forty-three indicators improved from February to March, while 40 indicators deteriorated and two were unchanged. Of the indicators that improved, 16 made negative contributions.
