Aug 31 (Reuters) - Wall Street looked set to open higher on Thursday as data showed inflation increased at its slowest pace since late 2015, boosting expectations that Federal Reserve will hold off from increasing interest rates again this year.
In the 12 months through July, the core personal consumption expenditures (PCE) price index - the Fed's preferred inflation measure - increased 1.4 percent after advancing 1.5 percent in June. Core PCE has undershot the U.S. central bank's 2 percent target for the past five years.
Consumer spending increased 0.3 percent last month, below the 0.4 percent rise expected by economists.
Labor Department data showed the number of Americans filing for unemployment benefits rose slightly last week.
The data precedes the more comprehensive jobs report on Friday, which will help investors gauge the strength of the labor market as they look for clues on the Fed's next move on rates.
"We do anticipate the overall market reaction to remain reticent ahead of the jobs data due tomorrow," said Naeem Aslam, chief market analyst at Think Markets UK.
