Over the last 12 months, the agency's Consumer Price Index increased 3.4% before seasonal adjustment. Both numbers were in line with the Dow Jones consensus, according to CNBC. 

The index for gasoline rose 3.9% in August, accounting for over one-third of the monthly, all-items increase, the agency reports.
