The manufacturing sector expanded in March, according to supply executives in the latest Manufacturing ISM Report on Business. The March PMI was 51.5 percent, 1.4 percentage points lower than February's 52.9 percent.

The New Orders Index registered 51.8 percent, a decrease of 0.7 percentage point from the reading of 52.5 percent in February. The Production Index registered 53.8 percent, 0.1 percentage point above the February reading of 53.7 percent.

The Employment Index registered 50 percent, 1.4 percentage points below the February reading of 51.4 percent, reflecting unchanged employment levels from February. Inventories of raw materials registered 51.5 percent, a decrease of 1 percentage point from the February reading of 52.5 percent. 

A reading above 50 percent indicates that the manufacturing economy is generally expanding; below 50 percent indicates that it is generally contracting.

"Comments from the panel refer to continuing challenges from the West Coast port issue, lower oil prices having both positive and negative impacts depending upon the industry, residual effects of the harsh winter, higher costs of healthcare premiums, and challenges associated with the stronger dollar on international business," said Bradley J. Holcomb, chairman of the Institute for Supply Management Manufacturing Business Survey committee.
