The MNI Chicago Business Barometer fell 4.3 points to 51.5 in August from 55.8 in July, led by a large setback in Order Backlogs and a deceleration in New Orders. Four of the five Barometer components fell between July and August. Only Employment increased, hitting a 16-month high. The latest fall left the Barometer, New Orders and Production running at the slowest pace since May, when they all slipped below 50.
