"In its forward guidance at the January meeting it had signalled a pause, and we think it will stick to it as inflation has eased," the HSBC said in a note.
RBI Governor Raghuram Rajan will announce the monetary policy on April 1 and expectations of a status quo are rising ever since the official data on consumer price inflation for February pointed to a cool down to 8.1 per cent.
The number is much closer to the RBI target of getting it to 8 per cent by January 2015, but worries like unseasonal rains and core inflation can make the situation tricky.
Quoting client survey, another British brokerage RBS said meanwhile that a majority of its respondents are expecting no change in the key policy rates.
However, it added that 14 per cent of them expect a 25 basis point cut, while 7 per cent expect a 25 bps hike in the repo rate.
On the possible post-policy reaction on the rupee, RBS said around 57 per cent of its respondents are looking to sell the rupee on upticks, with median expectations of 60 by March end. Around 31 per cent are looking to sell the rupee-dollar pair even if it trades lower post-policy.
Around 32 per cent are looking to buy the rupee if the market trades lower and 16 per cent are looking to buy the pair even if it trades higher, RBS said.
Rajan, who took charge last September, has built a reputation to surprise the markets. He raised the rates at his first policy announcement, foreseeing pressure on the inflation front and increased it again -- the third time since he took charge -- in January when the market was expecting a pause.
HSBC said that even though there might be a pause on Tuesday, the tightening is not over yet, especially given the fact that RBI has made its intention clear to get the Consumer Price Index, or retail inflation number to 6 per cent in the next two years.
In February, the Wholesale Price Index based inflation eased to 4.68 per cent but core inflation still remains sticky at over 3 per cent.
"This may not be the end of the tightening cycle; core inflation remains sticky, which may call for more hikes... The RBI is still expected to sound a hawkish tone and highlight the lingering upside risks to inflation," HSBC said.
