The Institute of Supply Management’s Index moved up 3.2points month on month, (m/m) to 61.3 for August 2018. This value is an encouraging sign for the manufacturing sector, as it is the highest index since February 2011. The index has also been greater than 50, (>50 = expansion) for thirty consecutive months. The new orders sub-index scored a 65.1, its fifteenth month in a row over 60. Overall, the ISM manufacturing index is strong and fundamentals remain favorable as the global economy strengthens and the U.S. dollar depreciates.

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.

ism-fig1Figure 1 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 59.87, up 3.9% 3 months year on year (y/y). When examined on a 12MMA y/y comparison, the index increased by 7.2% y/y.

Table 1 ism-table1breaks down the detail of the composite index and sub-indexes. The composite index score for August was 61.3. One year ago the composite index was a still solid at 58.8.

Breaking down the sub-indexes for the monthly numbers: Inventory, (not seasonally adjusted) sub-index moved-down 2.1 points m/m to 55.4 in August. ISM notes business is positive, new equipment sales and inquiries are strong, and the parts business is strong. Raw material costs, especially steel, appear to be leveling off. Cost of manufactured components has also leveled off. Most suppliers are willing and able to suppress cost increases. Tariff impacts are still a concern.

Of the 18 manufacturing industries, 16 reported growth in August, in the following order: Computer & Electronic Products; Apparel, Leather & Allied Products; Textile Mills; Paper Products; Miscellaneous Manufacturing; Electrical Equipment, Appliances & Components; Furniture & Related Products; Machinery; Nonmetallic Mineral Products; Transportation Equipment; Food, Beverage & Tobacco Products; Petroleum & Coal Products; Plastics & Rubber Products; Fabricated Metal Products; Chemical Products; and Printing & Related Support Activities. The two industries reporting contraction in August are: Wood Products; and Primary Metals

The production sub-index increased by 4.8 points to 63.8. The employment index moved up by 2.0 points to 58.5. Further evidence that the job market continues to be strong.

Manufacturing is off to a good start in 2018, the ISM manufacturing report continues to be encouraging. This month’s results showed a jump in the cost of raw materials, with prices for steel and other materials increasing because of tariffs imposed by the Trump administration.

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.
