Industrial Production Continues to Show Expansion In July 2012

Written by Steven Hansen

The headlines say Industrial Production (IP) increased 0.6% in July 2012 and up 4.4% year-over-year. Econintersect analysis using the unadjusted data is that IP was down 0.6% month-over-month and up 4.1% year-over-year.

The market was expecting a month-over-month increase of 0.6% to 1.0% (vs the headline 0.6%).

Econintersect’s analysis is that the manufacturing sub-index (which is more representative of economic activity) was also off 0.6% month-over-month. However, there are no recession indications in this data.

IP headline index has three parts – manufacturing, mining and utilities – manufacturing was up 0.5% this month (up 5.0% year-over-year), mining up 1.2% (up 6.0% year-over-year), and utilities were up 1.3% (down 2.4% year-over-year). Note that utilities are 10.3% of the industrial production index.

The growth rate for IP has been hovering around 4% +/- for almost a year.  The overall trend should be at least considered flat which means the rate of growth is constant.

Even with the poor performance of the utility sector of IP, the growth trend line has a slightly positive trend since mid 2011.

The manufacturing component of IP represents one of the strongest growth segments of the economy. It has a positive growth trend line. Economic downturns have been signaled by only watching the manufacturing portion of Industrial Production. Historically manufacturing year-over-year growth has been negative when a recession is imminent. This index is not indicating a recession is imminent.

Seasonally Adjusted Manufacturing Index of Industrial Production

The Fed explanation of the headline data:

Industrial production increased 0.6 percent in July after having risen 0.1 percent in both May and June.  Revisions to the rates of change for recent months left the level of the index in June little changed from its previous estimate. Manufacturing output rose 0.5 percent in July, the same rate of increase as was recorded for June. In July, the output of mines increased 1.2 percent, and the output of utilities rose 1.3 percent. At 98.0 percent of its 2007 average, total industrial production in July was 4.4 percent above its year-earlier level. Capacity utilization for total industry moved up 0.4 percentage point to 79.3 percent, a rate 1.0 percentage point below its long-run (1972–2011) average.

Econintersect uses unadjusted data and graphs the data YoY in monthly groups. The difficulty in IP is that this index has not settled down to the New Normal effects making evaluation and analysis problematic.

Regardless of interpretation, industrial production growth is NOT recessionary, and that the industrial portion of the USA economy is doing better than many other elements. Keep it real, here is a comparison between the survey predictions and the hard data.

In the above graphic, hard data is the long bars, and surveys are the short bars.  The arrows on the left side are the key to growth or contraction.

Caveats in the Use of Industrial Production Index

Industrial Production is a non-monetary index – and therefore inflation or other monetary adjustments are not necessary.

The monthly index values are normally revised many months after initial release and are subject to annual revision. The following graphic is an example of the variance between the original released value – and the current value of the index. Note that in general the current values are better than the original values – this is normally a sign of an improving economy.

This index is somewhat distorted by including utility production which is noisy, based primarily on weather variations.

There is some variance between the manufacturing component of industrial production which monitors production, and the US Census reported Manufacturing Sales. While it is true that these are slightly different pulse points (inventory not accounted in shipments) – they should not have different trends for long periods of time.

Econintersect determines the month-over-month change by subtracting the current month’s year-over-year change from the previous month’s year-over-year change. This is the best of the bad options available to determine month-over-month trends – as the preferred methodology would be to use multi-year data (but New Normal effects and the Great Recession distort historical data).
