June 2013 ISM Manufacturing Survey Slips Back Into Expansion

Written by

The ISM Manufacturing survey for June 2013 slipped back into expansion after the slight contraction in last month’s survey. The New Orders sub-index which historically correlates to the economy showed even a stronger expansion.

The ISM Manufacturing survey index (PMI) rose from 49.0 to 51.9 (50 separates manufacturing contraction and expansion). This was above expectations which were 50.5.

This index has been in a general downtrend since mid 2011. This is the first month of expansion after four months of decline.

Relatively deep penetration of this index below 50 has normally resulted in a recession.

The noisy Backlog of Orders fell from 48.0 to 46.5. 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.

Economic activity in the manufacturing sector expanded in June following one month of contraction, and the overall economy grew for the 49th consecutive month, say the nation’s supply executives in the latest Manufacturing ISM Report On Business®.

“The PMI™ registered 50.9 percent, an increase of 1.9 percentage points from May’s reading of 49 percent, indicating expansion in the manufacturing sector for the fifth time in the first six months of 2013. The New Orders Index increased in June by 3.1 percentage points to 51.9 percent, and the Production Index increased by 4.8 percentage points to 53.4 percent. The Employment Index registered 48.7 percent, a decrease of 1.4 percentage points compared to May’s reading of 50.1 percent. Manufacturing employment contracted for the first time since September 2009, when the index registered 47.8 percent. The Prices Index registered 52.5 percent, increasing 3 percentage points from May, indicating that overall raw materials prices increased from last month. Comments from the panel generally indicate slow growth and improving business conditions.”

Of the 18 manufacturing industries, 12 are reporting growth in June in the following order: Furniture & Related Products; Apparel, Leather & Allied Products; Paper Products; Electrical Equipment, Appliances & Components; Petroleum & Coal Products; Wood Products; Food, Beverage & Tobacco Products; Primary Metals; Fabricated Metal Products; Plastics & Rubber Products; Machinery; and Nonmetallic Mineral Products. The four industries reporting contraction in June are: Textile Mills; Transportation Equipment; Chemical Products; and Computer & Electronic 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. This subindex is in a long term downtrend – and remains close to contraction.

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 (dark blue bar) and US Census manufacturing shipments (lighter blue bar) to the ISM Manufacturing Survey (pink 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 jobs growth. 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.
