Stock futures were slightly lower on Monday ahead of the Federal Reserve's two-day meeting this week.

The Fedwill convene on Tuesday with an announcement and press conference set for Wednesday afternoon. The majority of economists don't expect the Fed to increase rates at this meeting after making initial liftoff in December. Consensus is for a June hike. 

Morgan Stanley analysts disagreed, however, saying they believe that the Fed won't make a move until December. The bank expects Treasury 10-year yields to fall to 1.45% by the end of September, nearing a record low reached in 2012. 

It's a busy week of monetary policy elsewhere. The Bank of Japan will meet on Tuesday and the Bank of England will meet on Thursday. The European Central Bank opted to cut rates further and expand its bond-buying program last week.

West Texas Intermediate crude oil dropped 2.2% to $37.69 a barrel.
