Money is on a September rate hike from the Federal Reserve but the latest data on wages threw some doubt into the ring on Friday. Wages and benefits rose 0.2% in the second quarter, the smallest gain since 1982, according to the Labor Department's Employment Cost Index. Economists had expected a 0.6% gain over the quarter after a 0.7% increase in the first quarter indicated a pickup in wage growth.

Investors have been on alert for any piece of data that could give the Fed pause in its rate-hiking plans. Consensus had been for the central bank to move off of crises-level rates as soon as September as economic conditions in the U.S. steadily improved.

"Today's report could increase uncertainty about the trajectory of wage growth and dampen expectations for a September hike," BNP Paribas analyst Laura Rosner wrote in a note.
