Forex traders said the Reserve Bank of India's monetary policy decision on Wednesday will be keenly watched by investors for further cues.

"The RBI monetary policy decision is due today. MPC is likely to hike repo rate by 35 bps to 6.25 per cent as core inflation still remains elevated sequentially," IFA Global Research Academy said in a note.
A bigger rate hike would also help maintain the differential with the US rates, support the forward premia in USD/INR and reduce the pressure on the rupee somewhat, it added.
