ISM Non-Manufacturing Index

ISM Non-Manufacturing Index: The Institute for Supply Management’s non-manufacturing index increased by 4.8 points month on month (+7.8% m/m) to 66.7 in October 2021.

The ISM non-manufacturing survey measures the rate and direction of change in activity in non-manufacturing industries. Surveys are sent to more than 400 purchasing managers in 18 industries. Survey responses reflect the change in the current month compared with the previous month. A value of 50 is neutral, while less than 50 denotes contracting non-manufacturing activity and greater than 50 denotes expanding activity.

At Gerdau, we closely monitor the ISM non-manufacturing index since it is an excellent barometer of the present strength, as well as a window on the likely short-run future, of the U.S. non-manufacturing economy. We have seen that a strengthening non-manufacturing economy translates to improved steel consumption.
