At 10:00 a.m., ISM will release its non-manufacturing composite, which is estimated at 56.2, versus 56.0 prior.
In a preview of ISM's report, BNP Paribas wrote: "Already quite elevated, we expect the non-manufacturing ISM index to remain at 56.0 in July. June retail sales disappointed, consumer confidence declined sharply in July, and we expect employment gains to have slowed a bit in July. It follows that we expect the growth pace in business activity to have stagnated a bit."
