Emerging market stocks hit a six and a half month peak on Tuesday and developing world currencies firmed against a soft dollar on expectations the U.S. Federal Reserve will strike a  dovish stance at its meeting this week.

The two-day meeting starts later on Tuesday. Money markets are pricing in a 99 percent probability of borrowing costs not being altered on Wednesday. They were left unchanged at the Fed's last rate-setting meeting in January.

MSCI's index of developing world stocks rose 0.2 percent, gaining for a third straight day, while MSCI'S emerging market currencies index ticked up 0.1 percent.

The Russian central bank is due to take a decision on borrowing costs on Friday, with markets pricing in a 87 percent chance of rates remaining at 7.75 percent, according to Refinitiv Eikon data.

Turkey's lira was on an even keel, while stocks  slipped away from a more than two week closing high notched on Monday as losses among financials and industrials sent the index 0.1 percent lower.
