The Fed has said it will raise rates when it sees sustained economic recovery. In latest look at business conditions nationwide, its Beige Book report on Wednesday, the Fed found that the economy kept expanding during the summer, driven by robust housing and auto sales.

"I think the market is trying to calm down a little bit with the fear factor reducing somewhat and the data points to a growing U.S. economy," said Peter Cardillo, chief market economist at Rockwell Global Capital in New York.
