The Federal Reserve will decide on Wednesday whether the U.S. economy is finally resilient enough to withstand less policy support, or whether it is prudent to wait a bit longer. With the world’s financial markets on edge, the U.S. central bank wraps up a two-day meeting with a highly anticipated policy announcement at 2 p.m. (1900 GMT), followed by Ben Bernanke’s last news conference as Fed chairman a half hour later. Recent growth in jobs and retail sales, as well as a fresh budget deal in Congress, has convinced a growing number of economists the time is right for the Fed to trim its $85 billion in monthly bond purchases. If it waits, the Fed might still decide to better telegraph how it plans to wind down the stimulus program, as a handful of its 18 policymakers have suggested in recent weeks.
