Fed to cut rates again

The Federal Reserve is expected to aggressively lower interest rates in its intensified battle against the credit crisis and spreading economic weakness. The question is whether all of the effort will turn the tide.

Federal Reserve Chairman Ben Bernanke and his colleagues have already been working overtime, employing a variety of novel approaches to keep the economy out of a recession or at least moderate the impact of any downturn.
More relief is expected Tuesday when the central bank is expected to cut a key interest rate by between one-half and a full percentage point.
