Manufacturing Update: Some Indicators Show Slower Growth

Written by Peter Wright

Economic indicators of manufacturing activity are strong, though the growth rate is slowing.

This report summarizes 11 data streams that describe the state of U.S. manufacturing in general and the steel industry in particular. We have reported on most of these separately in our Steel Market Update publications, and therefore will be brief in this summary. We don’t expect these data sources to all point in the same direction. Our intent in summarizing them in one document is to provide a consensus of the state of this critical steel consuming sector. Based on American Iron and Steel Institute estimates of steel mill shipments by market classification, almost 50 percent of the steel consumed in the U.S. is manufacturing-oriented. This breaks down to about 27 percent in ground transportation, 9 percent in machinery and equipment, 5 percent in appliances, 4 percent in defense and about 4 percent in containers.

Figure 1 summarizes the 11 individual data streams. All indicators except automobile sales and the ISM Index have positive growth on a year-over-year basis. However, growth rates of some indicators are slowing. The Bureau of Economic Analysis has not yet recovered from the government shutdown and the new orders and inventory data is a month in arrears.

The Industrial Production Index

Figure 2 shows the three-month moving average (3MMA) of the IP index since January 2007 as the blue line and the year-over-year growth as the brown bars. March 2017 was the first month of positive growth in the 3MMA since April 2015. Growth has been above 3 percent every month since November 2017, reaching 5.1 percent in October 2018 before declining to 4.1 percent in December. Manufacturing capacity utilization improved from 74.48 percent in January 2017 to 76.09 percent in December 2018, also on a 3MMA basis (Figure 3). This was the first time to exceed 76 percent since February 2015.

New Orders for Durable Goods (Advance Report)

The U.S. Census Bureau has not caught up from the shutdown and is a month in arrears. New orders for manufactured durable goods in November were unchanged from September and October on a 3MMA basis month over month and were up by 6.9 percent year over year. Figure 4 shows the 3MMA since January 2010 and that the rate of improvement in 2018 was the highest since 2014.

The Durable Goods Portion of GDP

The third estimate of Q3 2018 GDP growth was reported as 3.4 percent annualized, which was down only slightly from the first estimate and up from 2.2 percent in Q1 2018. The first estimate of GDP in Q4 2018 has been delayed. A subcomponent of the quarterly data is durable goods, which is part of the personal consumption calculation. It therefore contains no military hardware or civil aircraft data. This is shown in Figure 5 and, presumably because of the exclusions just mentioned, looks nothing like the blue line in Figure 4. The durable goods portion of GDP declined in Q3 2018, but the long-term trend is still very positive. 

New Orders for Manufactured Products

New orders for manufactured products as reported by the Census Bureau have been steadily increasing since mid-2016, but in November 2018 took a small step back. In November, year-over-year growth was 6.1 percent, down from 8.2 percent in October (Figure 6).

New Orders for Products Manufactured from Iron and Steel

Within the Census Bureau M3 manufacturing survey is a subsection for new orders for iron and steel products. Figure 7 shows the history since January 2000 and that orders declined in October and November. The growth rate year over year is still good at 16.1 percent.

Inventories of Products Manufactured from Iron and Steel

As orders for iron and steel products have surged, inventories have been built in anticipation of a continuation of the order situation. The inventory build was at a rate of 10.4 percent year over year in November (Figure 8).

Light Vehicle Sales in the U.S.

Automobile sales have trended down slightly in the last three years as measured by the cyclical peaks. Year over year on a 3MMA basis, sales were down by 1.3 percent. Sales in January totaled 16.7 million units annualized and were comprised of 67.3 percent light trucks and 32.7 percent autos. The declining sale of autos in the last three years has resulted in GM announcing its intent to close several small car plants. The light truck category includes SUVs and crossovers. Overall, sales are still higher than the pre-recession level (Figure 9). Import market share in January was 22.8 percent and has been drifting up since March last year.

Manufacturing Employment

Manufacturing employment plummeted during the recession and gradually improved from the spring of 2010 through 2014. Growth was flat in 2015 and declined slightly in 2016 when 23,000 jobs were lost during the year as a whole. There was a turnaround in 2017 and in the 12 months from February 2018 through January 2019, 261,000 manufacturing jobs were created (Figure 10). The motor vehicles and parts subcomponent of manufacturing employment had a net gain of only 22,000 in the same time frame. 

Manufacturing Productivity

The Bureau of Labor Statistics reported that in Q3 2018 manufacturing productivity surged by 1.5 percent year over year and maintained 0.7 percent growth in Q4 (Figure 11).

The ISM Manufacturing Index

The Institute for Supply Management’s Manufacturing Index is a diffusion index. ISM states: “Diffusion indexes have the properties of leading indicators and are convenient summary measures showing the prevailing direction of change and the scope of change. An index value above 50 indicates that the manufacturing economy is generally expanding; below 50 indicates the opposite.” Figure 12 shows the 3MMA of the ISM index from January 1997 through January 2019. The index surged from January 2016 through October 2017, but has declined every month since August last year. The 3MMA of the index in January was 56.63, down from 59.87 in August and down by 2.23 percent year over year.

SMU Comment:  Manufacturing activity is still strong though there is evidence of the growth rate slowing. The most encouraging current data point is the improvement in labor productivity in the third and fourth quarters of 2018. These were the best back-to-back quarters since mid-2013.  Automobile sales have been drifting down from an unsustainable level in late 2015 when they reached an annualized rate of over 18 million units. We should keep our eye on the ISM index, which though still strong is slightly negative year over year for the first time since August 2016.
