All eyes are on the Federal Reserve Wednesday as the central bank is expected to take the first step in winding down the program of asset purchases it has deployed to support the economy and markets.
U.S. stock futures edged higher, with investors cautious about taking any big bets ahead of the Fed's statement.
Many experts are forecasting the Fed will make a small cut to its asset purchases this month as the economy has been improving and unemployment falling. Others expect the tapering to start later.
The central bank is scheduled to release a statement at 2 p.m. ET following the conclusion of its latest policy-making meeting. Fed chair Ben Bernanke will then hold a press conference at 2:30 p.m. to discuss the Fed's latest assessment of the economy and its plans for the future.
"It's all about the Fed, not only the tapering decision, but also the statement language and the accompanying press conference," said Simon Smith, the London-based chief economist at FxPro.
Ahead of the announcement, investors received one disappointing reading on the health of the economy. The Census Bureau's monthly reports on housing starts and building permits came in below expectations.
