The Fed is also expected to resume discussions on how to signal future policy moves to the public more clearly. Since August 2011, the Fed has identified a target date to try to reassure markets that it doesn't plan to raise short-term rates soon. Some Fed officials, however, oppose using a target date to signal the earliest when it might start raising rates. They've been urging that future interest-rate moves be linked to how the economy is faring as measured by unemployment and inflation.

Many private economists expect no change in the Fed's communications strategy this week.
