(Reuters) - U.S. stock index futures slipped on Thursday after hotter-than-expected producer prices data contrasted with recent tame consumer prices data that had boosted bets of Federal Reserve interest rate cuts this year.

Data from the Labor Department showed the Producer Price Index rose 3.3% on an annual basis in July, compared with a 2.5% gain expected by economists polled by Reuters. On a monthly basis, it was 0.9%, compared with an estimated 0.2% rise.

Excluding volatile food and energy components, core PPI increased 3.7% on an annual basis, compared with an expected 2.9% rise.

A separate report showed the number of Americans filing new applications for unemployment benefits came in at 224,000 for the week ended August 9, compared with estimates of 228,000.

At 08:34 a.m. ET, Dow E-minis were down 171 points, or 0.38%, S&P 500 E-minis were down 27.5 points, or 0.42%, and Nasdaq 100 E-minis were down 113 points, or 0.47%.
