The jobs market also is unlikely to get much help from business investment, which Yellen and her Fed cohorts have cited as a significant concern. Nondefense capital goods orders are tracking for a decline of 6.3 percent annualized, which Deutsche Bank economists say is "an excellent proxy" for capital spending.
"Importantly, the recent weakness in capital spending has been broad based and not simply attributable to the energy sector. Moreover, forward-looking surveys of capital spending remain depressed, pointing to negligible improvement in the back half of the year," Deutsche economists Aditya Bhave and Joseph LaVorgna said in a recent note to clients.
"The weakness in capital expenditures has not gone unnoticed by monetary policymakers, most notably Fed Chair Yellen, who expressed concern that the deterioration in business investment could signal a desire on the part of firms to expand their operations at a slower pace," they added.
On top of all the global developments, such as June's Brexit referendum, that have scared Fed policymakers off what was supposed to be a year of consistent rate hikes, the continued job market softness will only add to their trepidation.
The Fed has been hoping to see healthy levels of inflation in the economy, but nearly a decade of ultra-accommodative monetary policy has fallen short in that regard, with most inflation gauges running below the central bank's 2 percent target.
The fed funds futures market currently assigns no chance of a rate hike at this month's Federal Open Market Committee meeting, and only a 46.5 percent chance for one by the end of 2016.
