Growth in Philadelphia-area manufacturing activity showed a significant slowdown in the month of May, the Federal Reserve Bank of Philadelphia revealed in a report on Thursday.
The Philly Fed said its current general activity index tumbled to 2.6 in May from 17.6 in April, hitting its lowest level in two years.
While a positive reading still indicates growth in regional manufacturing activity, economists had expected the index to show a much more modest drop to 16.0.
Looking ahead, the Philly Fed said the survey's future indexes remained positive but reflect muted optimism for growth over the next six months.
