The monetary policy committee cut the repo rate by an unconventional 35 basis points to 5.40 per cent.

Fixing India's weak growth has become the highest priority while a benign inflation outlook has given the central bank room to cut rates although transmission remains inadequate, monetary policy committee meeting minutes showed.

The Reserve Bank of India (RBI) lowered its benchmark interest rates for a fourth straight meeting this month with a slightly bigger than expected cut, underscoring its worries about the near-five year low economic growth pace.

The six-member monetary policy committee (MPC) cut the repo rate by an unconventional 35 basis points (bps) to 5.40 per cent.

"Given the current and evolving inflation and growth scenario at this juncture, it can no longer be a business as usual approach. The economy needs a larger push," Governor Shaktikanta Das said in the minutes, released on Wednesday.

Annual retail inflation in July was 3.15 per cent, down from an eight-month high of 3.18 per cent in June and staying below the central bank's 4 per cent medium-term target for a 12th straight month, raising expectations for a cut in October.

Last week, a Reuters poll predicted the RBI would ease its benchmark rate by 25 basis points again to 5.15 per cent at its October meeting, followed by a 15 basis point cut in the first quarter of 2020.

Since February, the RBI has cut the repo rate by a total 110 basis points (bps), but most Indian banks have not come close to following suit.

"Under prevailing circumstances, the immediate transmission should be considered not so much in terms of the bank deposit and lending rates but more specific rates influencing new investments such as housing loans, vehicle loans and long term bonds," said one MPC member, Ravindra Dholakia.

Most members of the committee, however, felt rate transmission would be faster in coming weeks and months aided by surplus liquidity in the banking system.

The RBI is also looking to get banks to link some new loans to its key policy rate or other external benchmarks, Mr Das said on Monday, as he pushes them to cut rates faster to stimulate growth.

"While they are giving stylised arguments to justify their recommendations, none of them has made a clear statement on the outlook or possible timelines for recovery," said Rupa Rege Nitsure, chief economist at L&T Financial Holdings.

"A lot depends on how promptly fiscal authorities undertake remedial measures."

Finance Minister Nirmala Sitharaman has recently held several meetings with industry leaders, who have called for stimulus measures, including tax rebates, to support consumer demand and private investment.

Pami Dua, another member of the MPC, said while monetary policy can impact cyclical factors, it has its limits when the slowdown is structural in nature.

"Therefore, investment-focused fiscal policy and active continuation of structural reforms are imperative at this juncture," Ms Dua said.

The government was looking into policy issues such as exempting foreign portfolio investor trusts from recently imposed high tax, deferring a proposal to raise minimum public share holding in listed companies to 35 per cent from 25 per cent and easing of banking credit, a source told Reuters on Friday.

"Given the evolving growth-inflation risk picture, monetary policy should be used judiciously," member Chetan Ghate said.
