While the market is not expecting a big rate surprise, investors will be closely watching the Fed's comment for clarity on future rate trajectory, per analysts.

"We expect caution to prevail in markets ahead of the Fed rate decision," said Siddharth Khemka, head of retail research at Motilal Oswal Financial Services.

Both the Nifty 50 and Sensex closed flat on Tuesday as a slide in consumer stocks offset an uptick in metal stocks.

Oil prices eased after hitting a three-month high on Tuesday on China's plans to support its economic recovery and signs of tighter supplies. A rise in crude prices is a negative for oil-importing countries like India, where oil constitutes a significant part of the import bill. [O/R]
