ISM Manufacturing Index

ISM Manufacturing Index: The Institute for Supply Management’s manufacturing index moved down 1.7 points month on month (m/m) to 55.4 for April 2022; this value is stronger than the forecast of 50.  The new orders sub-index scored a 53.5. Overall, the ISM manufacturing index is strong, while the global economy is beginning to strengthen again following shutdowns throughout Covid-19.

The ISM manufacturing index is based on surveys of 300 purchasing managers in 17 industries. The survey is a diffusion index calculated as a percent of responses. A value of 50 is neutral, while less than 50 denotes contracting manufacturing activity and greater than 50 denotes expanding activity.

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 U.S. manufacturing.
