Greenspan said the economy regained traction and inflation eased, but that the oil outlook was uncertain and budget prospects were troubling over the long-term. Stocks moved lower following his comments.
Data also raised concern over the economy. The Federal Reserve's Beige Book showed slower economic growth in some districts in July and August.
