Speculation over the Fed's likelihood of moving on interest rates sooner rather than later has caused waves on Wall Street in recent weeks.

The chances of a rate hike in September sit at 15%, according to CME Group fed funds futures. Most analysts are betting on a rate hike in December, which has a 48% likelihood.
The FOMC is set to meet for two days beginning Tuesday, culminating in an announcement, forecasts and press conference from Fed Chair Janet Yellen on Wednesday afternoon.

"While we don't believe the policy makers will raise rates at the upcoming meeting, we foresee a more hawkish group emerging to prepare the markets for a rate increase in December."
The Bank of Japan was also on watch as members meet for a two-day discussion on monetary policy. Unlike the Fed, market analysts are mixed on whether the central bank will make a move, including increasing stimulus, this month.
