U.S. stock index futures fell on Monday as investors worried about the Federal Reserve pressing ahead with its plan to raise interest rates this year. 

* Global markets were lower after a two-day meeting of G20 leaders ended with no new plan to spark global growth.

* Brent crude futures edged higher on rising hopes the market has bottomed out.

* Wall Street closed lower on Friday, after a rally earlier in the week lost steam.

* The S&P 500 is poised for three straight months of declines, after a sharp drop in crude prices sparked one of the worst starts to a year for stocks. Up to Friday's close, the index was down 4.7% this year.

* Still, the index closed above its 50-day moving average, which some traders say is a sign of improving sentiment.

* Adding to the optimism was upbeat data, including strong consumer spending trends, released last week that suggested the U.S. economy was recovering better than expected.

* Federal funds futures implied traders see a 38% chance of the Fed raising rates in June and a 57% chance in December, according to CME Group's FedWatch program.

* New York Fed President William Dudley is slated to speak on policy at a banking conference in China.
