An increasing number of economists expect the central bank to raise interest rates, a Reuters poll showed, but most still think it will stay put and use this week's meeting to prepare for a rate increase in August.
An unexpected surge in inflation and economic growth rates have brought forward expectations for the next rate hike by more than a year, when just over a month ago, the RBI wasn't expected to raise rates until the second half of 2019.
The broader NSE Nifty was up 0.40 percent at 10,635.65 as of 0556 GMT, while the benchmark BSE Sensex was 0.42 percent higher at 35,048.48.
"There is expectation of some relief move from the RBI meeting, while the early onset of the monsoon is also giving some kind of support," said Anand James, chief market strategist at Geojit Financial Services.
"Three days of selling have found some fresh buyers, because of which there is value buying happening at lower levels..."

IDFC Bank Ltd soared as much as 5.1 percent after it received a "no objection" from the central bank for acquiring Capital First Ltd, which was up 3.7 percent.
