According to Dilip Parmar, Research Analyst, HDFC Securities, the Indian rupee strengthened for the second day in a row following dollar inflows and risk-on sentiments ahead of the RBI monetary policy decision.

RBI is scheduled to announce its bi-monthly monetary policy meeting's outcome on Thursday. RBI is largely expected to leave the repo rate unchanged at 6.5 per cent.

"The market is pricing in pause for a second straight meeting as inflation eases. All eyes will be on a policy stance, which might support growth as inflation could cool further in the months ahead on an expectation of better monsoons and lower commodity prices," Parmar said.
