July 2014 ISM Manufacturing Survey Insignificantly Improves - Expansion Continues
Written by Steven Hansen
The ISM Manufacturing survey for July 2014 continues to indicate manufacturing growth expansion with an insignificant increase in the rate of growth.
The ISM Manufacturing survey index (PMI) rose insignificantly from 55.3 to 57.1 (50 separates manufacturing contraction and expansion). This was within expectations which were 55.0 to 56.8 (consensus 56.0).
This index had been in a general downtrend since mid 2011. This is the fourteenth month of expansion. The regional Fed manufacturing surveys were indicating growth in July, and now the ISM indicates manufacturing shows expansion in July also.
Relatively deep penetration of this index below 50 has normally resulted in a recession.
The noisy Backlog of Orders improved from 48.0 to 49.5 – but still is showing growth. Backlog growth is an indicator of improving conditions; a number below 50 indicates contraction. Backlog accuracy does not have a high correlation against actual data.
Excepts from the ISM release:
Economic activity in the manufacturing sector expanded in July for the 14th consecutive month, and the overall economy grew for the 62nd consecutive month, say the nation's supply executives in the latest Manufacturing ISM® Report On Business®.
"The July PMI® registered 57.1 percent, an increase of 1.8 percentage points from June's reading of 55.3 percent, indicating expansion in manufacturing for the 14th consecutive month. The New Orders Index registered 63.4 percent, an increase of 4.5 percentage points from the 58.9 percent reading in June, indicating growth in new orders for the 14th consecutive month. The Production Index registered 61.2 percent, 1.2 percentage points above the June reading of 60 percent. Employment grew for the 13th consecutive month, registering 58.2 percent, an increase of 5.4 percentage points over the June reading of 52.8 percent. Inventories of raw materials registered 48.5 percent, a decrease of 4.5 percentage points from the June reading of 53 percent, contracting after five months of consecutive growth. Comments from the panel are generally positive, while some indicate concern over global geopolitical situations."
Of the 18 manufacturing industries, 17 are reporting growth in July in the following order: Furniture & Related Products; Textile Mills; Apparel, Leather & Allied Products; Printing & Related Support Activities; Plastics & Rubber Products; Paper Products; Nonmetallic Mineral Products; Food, Beverage & Tobacco Products; Machinery; Chemical Products; Miscellaneous Manufacturing; Fabricated Metal Products; Electrical Equipment, Appliances & Components; Petroleum & Coal Products; Primary Metals; Transportation Equipment; and Computer & Electronic Products. The only industry reporting contraction in July is Wood Products.
It is interesting to note that ISM Manufacturing represents less than 10% of USA employment, and approximately 20% of the business economy. Historically, it could be argued that the production portion of ISM Manufacturing leads the Fed’s Industrial Production index – however the correlation is not strong when looking at trends.
New orders have direct economic consequences. Expanding new orders is a relatively reliable sign a recession is NOT imminent. However, New Orders contraction have given false recession warnings twice since 2000.
However, holding this and other survey’s Econintersect follows accountable for their predictions, the following graph compares the hard data from Industrial Products manufacturing subindex (blue bar) and US Census manufacturing shipments (red bar) to the ISM Manufacturing Survey (purple bar).
Comparing Surveys to Hard Data
Caveats on the use of ISM Manufacturing Index:
This is a survey, a quantification of opinion – not facts and data. However, as pointed out above, certain elements of this survey have good to excellent correlation to the economy. Surveys lead hard data by weeks to months, and can provide early insight into changing conditions.
Many use ISM manufacturing for guidance in estimating manufacturing employment growth. Econintersect has run correlation coefficients for the ISM manufacturing employment and the BLS manufacturing employment data series above going back to 1988, using quarterly data. The coincident correlations are actually negative, but poor (r = -0.2 to -0.4 for various time periods examined). See here for definitions.
Before 2000 the ISM employment data had a weak positive correlation to the BLS data 4 to 7 quarters later (r values above 0.6). Since 2000 the correlations for ISM manufacturing employment as a leading indicator for the BLS manufacturing employment have been between 0 and 0.3 for r (correlation coefficient). These values define correlations as none to poor.
In other words, ISM employment index is not useful in understanding manufacturing jobsgrowth. The graph below shows BLS manufacturing employment month-over-month gains against the ISM Manufacturing employment index.

The ISM employment index appears useful in predicting turning points which can lead the BLS data up to one year.
