The US non-farm payroll report will be closely eyed by the markets when it's released Friday because the data may provide clues as to when the Federal Reserve might raise interest rates again.

Economists expect the Labor Department payroll report to show that employers added about 180,000 jobs in July.

June's figures surpassed forecasts and rebounded from May's unexpectedly weak growth.

Wednesday's ADP employment report showed private employers added 9,000 more jobs than anticipated in July.

A strong jobs report in July is likely to fuel speculation that the Fed will raise interest rates soon due to improvements in the labor market and the economy.
