The Chicago PMI (ISM-Chicago Business Barometer) measures the performance of the manufacturing and non-manufacturing sector in the Chicago region. The Index is computed from five weighted raw indexes: Production (0.25), New Orders (0.35), Order Backlog (0.15), Employment (0.10), and Supplier Deliveries (0.15) and then seasonally adjusted to support month-to-month comparisons. A reading above 50 indicates an expansion; below 50 represents a contraction; while 50 indicates no change. Chicago PMI is released one day before the ISM Manufacturing Index.

Latest Updates

The Chicago Business Barometer declined to 41.5 in August 2025 from 47.1 in July, missing market expectations of 46. The index remained below the 50-point threshold for the 21st consecutive month, signaling continued contraction in business activity. The decline was primarily driven by a sharp drop in new orders (-10.8 points), the largest since September 2023, followed by a decrease in production (-3.6 points), marking the fifth consecutive monthly decline and the weakest level since December 2024. Order backlogs fell (-1.4 points), while inventories declined (-2.3 points), reflecting reduced demand and cautious stockpiling. Supplier deliveries rose (+5.8 points), partially offsetting the slowdown, while inflationary pressures eased, with the prices paid index falling (-8.3 points), matching July’s pace.
