Along with rate hikes, steps to tighten liquidity are expected to accompany on Wednesday, adding upward pressure to bond yields and increasing the need for the Reserve Bank of India (RBI) measures to support government borrowing, Reuters said.


The rise in interest rates is not in doubt, because the governor of the RBI said on May 23 that the decision would be a "no brainer".


Economists polled by Reuters expect a rise of 25 to 75 basis points, which will follow a 40-basis-point rise in May that kicked off the central bank's tightening cycle, which economists expect to be relatively short.


"A hike at this week's RBI ... policy meeting is a foregone conclusion," said Radhika Rao, senior economist at DBS Bank. "Inflation has proved to be persistently high in the past three years, even as drivers have changed - from supply bottlenecks to commodities and reopening pressures," she added.


Retail prices in April were 7.79 per cent higher than a year earlier, exceeding the RBI's tolerance band for inflation of 2 per cent to 6 per cent for a fourth month in a row. Inflation is expected to stay high in the near future.


RBI Governor Shaktikanta Das said late last month the bank's primary focus was to bring inflation down closer to target but it could not disregard concerns around economic growth.


The market is pricing in an increase of about 50 basis points on Wednesday.


Analysts also expect the RBI to reduce liquidity, reinforcing its fight against inflation and extending its effort to return monetary conditions to what they were like before the pandemic prompted radical action to stimulate the economy.


"We see the RBI continuing with measures to absorb liquidity," BofA Global Research said in a note on June 3, predicting a 50-basis-point increase in the cash reserve ratio (CRR) for banks, which would absorb around Rs 870 billion in the banking system.


Rao at DBS said: "Further CRR increases are on the cards to lower the liquidity surplus and aid transmission" - that is, to assist rises in interest rates to affect the economy.


Tighter liquidity will add upward pressure to bond yields. The benchmark 10-year yield has already risen more than 100 basis points in 2022, driven higher by global oil prices and rising expectations for short-term interest rates.
