The Chicago Business Barometer, also known as the Chicago Purchasing Manager's Index, is similar to the national ISM Manufacturing indicator but at a regional level and is seen by many as an indicator of the larger US economy. It is a composite diffusion indicator, made up of production, new orders, order backlogs, employment, and supplier deliveries compiled through surveys. Values above 50.0 indicate expanding manufacturing activity.

The latest Chicago Purchasing Manager's Index, or the Chicago Business Barometer, rose in June to a value of 64.1 from 62.7 in May, which was above the Investing.com forecast 60.0.

Here is an excerpt from the press release:

“Stronger outturns in May and June left the MNI Chicago Business Barometer broadly unchanged in Q2, running at a pace similar to that seen throughout 2017. While impressive, supply-side frustrations are undermining firms’ productive capacity,” said Jamie Satchi, Economist at MNI Indicators.

“Confusion surrounding the trade landscape continues to breed uncertainty among businesses and their suppliers and has led to many firms’ altering their immediate purchasing decisions,” he added. [Source]
