The Institute for Supply Management's index for US manufacturing fell to 52.5 in July from June's 53.2, missing expectations for a reading of 53.0 but above the 50 level that separates an expansion from a contraction in sector activity.

The ISM said demand and industrial production slowed in transport and equipment while poor weather affected construction.

In contrast, Markit's final US manufacturing purchasing managers' index rose to 52.9 in July from 51.3 in June, in line with the flash reading and analysts' expectations.
