The Philly Fed's Manufacturing Business Outlook Survey is a monthly report for the Third Federal Reserve District, covers eastern Pennsylvania, southern New Jersey, and Delaware. While it focuses exclusively on business in this district, this regional survey gives a generally reliable clue as to the direction of the broader Chicago Fed's National Activity Index.

The latest Manufacturing Index came in at -12.7, down 49.4 from last month's 36.7. The 3-month moving average came in at 13.7, down from 18.7 last month. Since this is a diffusion index, negative readings indicate contraction, positive ones indicate expansion. The Six-Month Outlook came in at 35.2, down from the previous month's 45.4.

The -12.7 headline number came in below the 10.0 forecast at Investing.com.

Here is the introduction from the survey:

Manufacturing firms reported a significant weakening in regional manufacturing activity this month, according to results from the Manufacturing Business Outlook Survey. The survey’s current indicators for general activity, new orders, and shipments fell precipitously this month, coinciding with developments related to the coronavirus. The firms reported a slight overall increase in employment, however, and a near-steady workweek. The broadest indicator of future activity weakened somewhat but remained elevated; however, firms still expect overall growth in new orders, shipments, and employment over the next six months.

The first chart below gives us a look at this diffusion index since 2000, which shows us how it has behaved in proximity to the two 21st century recessions. The red dots show the indicator itself, which is quite noisy, and the 3-month moving average, which is more useful as an indicator of coincident economic activity. We can see periods of contraction in 2011, 2012 and 2015, and a shallower contraction in 2013. 2016 saw an improvement but has since lost its gains and has been detracting.

In the next chart, we see the complete series, which dates from May 1960. For proof of the high volatility of the headline indicator, note that the average absolute monthly change across this data series is 7.7.

The next chart is an overlay of the General Activity Index and the Future General Activity Index — the outlook six months ahead.
