Chicago Business Barometer soars in May
Written by Ethan Bernard
The Chicago Business Barometer increased in May after easing the two previous months.
The Barometer rose 13.5 points from April to 62.7 this month, according to the latest report from Market News International (MNI) and the Institute for Supply Management (ISM).
It’s now at its highest point since January 2022, and back in expansionary territory after one month below the neutral 50 mark.
The Barometer is a diffusion index. Readings above 50 indicate improving business conditions. Those below 50 indicate contraction.
This month’s increase was attributed to a rise in new orders, production, order backlogs, and supplier deliveries. However, a decline in employment marginally offset the hike.
The jump represents the second-largest monthly increase since the Barometer began back in February 1967. Only July 2020 saw a larger monthly spike.
The Barometer surveys purchasing and supply management professionals in the Chicago area each month to gauge company-level business conditions. The survey ran from May 1-14.
