The index’s three-month moving average, CFNAI-MA3, declined to –0.12 in April from +0.08 in March, turning negative for the first time since December 2010. April’s CFNAI-MA3 suggests that growth in national economic activity was somewhat below its historical trend. With regard to inflation, the CFNAI-MA3 suggests subdued inflationary pressure from economic activity over the coming year.

Production-related indicators made a contribution of –0.16 to the index in April, down sharply from +0.31 in March. Manufacturing production decreased 0.4 percent in April after rising for nine consecutive months, and manufacturing capacity utilization declined to 74.4 percent in April from 74.8 percent in March. Parts shortages that resulted from the earthquakes in Japan contributed to a decline in motor vehicle and parts production.
