ISM Manufacturing Index: The Institute of Supply Management’s Index moved down 2.1 points on month, (m/m) to 49.1 for August 2019. This is the first time the index has been lower than 50 since August 2016. Before this month, the index had been greater than 50, (>50 = expansion) for thirty-five consecutive months. The new orders sub-index scored a 47.2. Overall, the ISM manufacturing index is weakening.
The ISM manufacturing index is based on surveys of 400 purchasing managers in 20 industries. The survey is a diffusion index calculated as a percent of responses. A value of 50 is neutral, while less than 50 is contracting and greater than 50 is expansionary.
Figure 1 breaks down the detail of the composite index and sub-indexes. The composite index score for August is 49.1. One year ago, the composite index was a strong at 61.3.
Figure 2 shows the history of the ISM manufacturing index from 2003 to present. On a 3 month moving average, (3MMA) basis, the index posted a value 50.67, down 1.9% 3 months year on year (y/y). When examined on a 12MMA y/y comparison, the index decreased by 1.8% y/y.
Breaking down the sub-indexes for the monthly numbers: Inventory, (not seasonally adjusted) sub-index moved-up 0.4 points m/m to 49.9 in August.

An Institute for Supply Management respondent stated, “Slightly lower rate of incoming orders may be seasonal or a sign of a general slowdown. Monitoring closely.” (Fabricated Metal Products)
At Gerdau we closely monitor the ISM manufacturing index since it is an excellent barometer of the present strength as well as a window on the likely short-run future of US manufacturing.
