Chicago Business Barometer fell to 18-month low in November
Written by Brett Linton
The Chicago Business Barometer tumbled to an 18-month low in November, according to Market News International (MNI) and the Institute for Supply Management (ISM). The barometer surveys purchasing and supply management professionals in the Chicago area each month to gauge company-level business conditions. November marks the 24th consecutive month that the index has been in contraction.
The November reading dipped seven points from October to 36.3, the lowest measure recorded since May 2024. This is a diffusion index, where a reading above 50 indicates improving business conditions and a reading below that indicates contraction. The index has only signaled expansion one time in the past three years (November 2023).
