U.S. futures are pointing higher before the release of key inflation data for July that could provide a better idea of where prices are heading.

Futures for the S&P 500 gained 0.3% Wednesday and futures for the Dow Jones Industrial Average edged up 0.1%. Nasdaq futures gained 0.7%.

Rising costs are being closely watched by the Federal Reserve as well as Republicans facing tough midterm elections and millions of Americans struggling with higher prices for everything from groceries to gasoline. Economists expect new data to show to show inflation slipped to 3.4% in July from 3.5% in June.

Higher rates also would undercut prices for stocks and other investments.
