Analysts at TD Securities are expecting the U.S. ISM non-manufacturing index to drop modestly to 55.1 in September after a notable 2.7 gain to 56.4 in August.

• “This would come on the heels of a sharply lower ISM manufacturing print for September that dragged the index deeper into contractionary territory and would suggest the services sector remains largely healthy despite the worsening outlook for the industrial sector.”
