According to Reuters, U.S. consumer sentiment fell to its lowest level in five months in September, as consumers saw higher interest rates and slower economic growth ahead.

The Thomson Reuters/University of Michigan's final reading on the overall index on consumer sentiment slipped to 77.5 in September from 82.1 in August – the lowest final reading since April.

"While few consumers expected a federal shutdown, complaints about government policies have risen, and more importantly, prospects for job growth have diminished," survey director Richard Curtin said in a statement.
