Consumer prices rose a seasonally adjusted 0.2 per cent in September in the United States due largely to a jump in energy prices, the Bureau of Labour Statistics reported Wednesday. The consumer price index is up 1.2 per cent for the last 12 months. So-called core inflation, which excludes volatile food and energy prices, rose by a seasonally adjusted 0.1 per cent in September, dpa reported. The September inflation data was delayed from its scheduled October 16 release date, due to a partial government shutdown over a budget stalemate in Congress.
