The Fed has warned that the economic outlook is weak
January's data from the Federal Reserve was the same as December's figure, and in line with market expectations.
Output was mixed across the various manufacturing sectors, with carmakers and mining firms seeing production fall, while computer makers saw a rise.

Sarah Bloomfield, economist at the Centre for Economics and Business Research, said the Fed's latest industrial production data was further evidence of the impact of the US housing slump.
"This could put additional downward pressure on the dollar," she said.
