The Chicago Fed's National Activity Index (CFNAI), a monthly index designed to gauge overall economic activity and related inflationary pressure, showed that economic activity was slower in March. The index slipped to -0.23 in March from 0.76 in February, while the more-representative three-month moving average fell to -0.01 from 0.12, its lowest level since October.The CFNAI is a weighted average of 85 existing monthly indicators of national economic activity.
