New Delhi, May 5 (PTI) The Reserve Bank may cumulatively cut the key interest rate in the range of 125-150 basis points this fiscal amid benign inflationary patterns, an SBI Research report said on Monday.

The study suggested that the central bank should go for "jumbo" rate cuts of 50 bps as it would be more effective.

The sharp moderation in consumer price index based inflation, hitting a 67-month low of 3.34 per cent in March 2025 due to sharp correction in food inflation, bodes well for lowering the average CPI headline forecast for FY2025-26 below 4 per cent now (with below 3 pre cent in Q1FY26), the report said.

The nominal GDP growth is expected to be in the range of 9-9.5 per cent for FY2025-26 (Budget: 10 per cent), signifying a Goldilocks period to slash the policy rates given the low growth and low inflation, said the research report from the State Bank of India's Economic Research Department titled 'Inflation and Rate Cut Trajectory'.

"With multi-year low inflation in March and benign inflation expectations going forward, we expect rate cuts of 75 basis points in June and August (H1) and another 50 bps cut in H2 -- cumulative cuts of 125 bps going forward while 25 bps rate cut has already been initiated in Feb '25 (that could put the terminal rate at ~5.0 per cent - 5.25 per cent by March 2026)," the report said.

"However, we feel, jumbo cuts of 50 bps, could be more effective than secular 25 bps tranches spread over the horizon," it added.

Based on the available estimates of natural rate, the report said that the neutral nominal policy rates work out at 5.65 per cent. The current trajectory of the domestic inflation is well within the band of 2-6 per cent with average inflation based on available data placed at 4.7 per cent.

"Assuming further convergence of domestic inflation to target, the possibility of cumulative rate cut of 125-150 bps is also possible by March 2026...implying repo rate declining below neutral rate," the SBI study said.

It further said that in response to the 50-bps cut in the policy repo rate since February 2025, banks have reduced their repo-linked EBLRs by a similar magnitude.

While the MCLR, which has a longer reset period and is referenced to the cost of funds, may get adjusted with some lag. Larger transmission to deposits rates is expected in the coming quarters.

Interest rate cuts proposed as cumulative reductions, favouring jumbo tranches to speed monetary transmission and easing. SBI Research forecasts cumulative policy rate reductions by March 2026 contingent on sustained disinflation, recommending larger 'jumbo' cuts rather than small incremental steps. The report bases this on easing CPI inflation and a neutral nominal policy rate near 5.65 per cent, anticipates repo linked lending rates to transmit quickly while MCLR and deposit rates adjust with lag, and notes an exchange rate outlook consistent with the projected easing.
