RBI rate hike: SBI Research says 25 bps increase now decisively likely
Synopsis
SBI Research has made a decisive call: a 25 bps rate hike by the RBI is now the most likely outcome of the October MPC meeting. With CPI at 4.82%, the rupee under FPI-driven pressure, a historic monsoon deficit threatening Rabi output, and a ₹8.2 lakh crore liquidity gap lurking beneath headline numbers, the report argues that pre-emptive action is no longer optional — it is overdue.
Key Takeaways
SBI Research says the balance of risks now decisively favours a 25 bps rate hike by the RBI at the upcoming October MPC meeting .
The MPC meets from 5–7 October 2026 to decide on the benchmark repo rate.
CPI inflation rose to 4.82 per cent in August, up from 4.45 per cent in July, reflecting broad-based price pressures.
FPIs sold $4.45 billion in the preceding week, adding to rupee depreciation pressure.
The 2026 monsoon was the 4th driest since 2000 at 87 per cent of LPA , raising Rabi crop risks.
SBI estimates a ₹8.2 lakh crore deposit creation gap for banks to support 16 per cent credit growth in FY27.
SBI Research on Friday, 2 October 2026 said the balance of risks has tilted decisively in favour of a 25 basis point (bps) rate hike by the Reserve Bank of India (RBI) at this juncture, citing broadening inflationary pressures, worsening global macroeconomic conditions, evolving liquidity dynamics, and a renewed global repricing of risks. The research arm of State Bank of India (SBI) argued that the case for pre-emptive monetary action has strengthened considerably ahead of the upcoming policy review.
MPC Meeting and Rate Outlook
The RBI's Monetary Policy Committee (MPC) is scheduled to convene from 5–7 October to decide on the benchmark repo rate. According to the SBI report, given the convergence of geopolitical tensions, crude-price risks, and global risk repricing, 'it would be prudent to act pre-emptively rather than being behind the curve.' The report also anticipates that the RBI will revise its GDP forecast upward by 30 bps and its inflation forecast upward by 20 bps for FY27.
Inflation Turns Broad-Based
Consumer Price Index (CPI) inflation climbed to 4.82 per cent in August, up from 4.45 per cent in July, underscoring what SBI Research describes as increasingly broad-based price pressures. The report noted that the rising trajectory, combined with external headwinds, leaves limited room for the central bank to hold rates without risking a credibility deficit.
Rupee Under Pressure, Forex Flows Tested
The Indian rupee has been caught in a downward spiral, compounded by a strengthening Dollar Index and persistent selling by Foreign Portfolio Investors (FPIs), who offloaded $4.45 billion in the week leading up to the report. SBI Research said the RBI's ability to meaningfully intervene and counter speculative forces will be a 'litmus test of its innate strength.'
Monsoon Deficit and Rabi Risks
The report flagged that the 2026 monsoon was the fourth driest since 2000, with rainfall at just 87 per cent of the Long Period Average (LPA) and 43 per cent of districts recording deficient rainfall. Strong El Niño conditions and a forecast of below-normal October rainfall could pose further risks to Rabi crop output, adding an agriculture-driven dimension to the inflation outlook.
Liquidity Gap and Credit Growth Concerns
While headline liquidity appears elevated — partly due to record $143.5 billion forex inflows under a special swap facility — SBI Research cautioned that effective liquidity creation is significantly lower once regulatory requirements such as CRR, SLR, and LCR are factored in. The report estimated a gap of ₹8.2 lakh crore in deposit creation by banks, even accounting for projected 16 per cent credit growth for FY27, due to regulatory dispensation and requirements under UPI and Sparsh frameworks. The report concluded that system liquidity will self-adjust and no additional manoeuvring is required. However, it advised policymakers and regulators to remain prepared for scenarios where evolving macroeconomic conditions may necessitate unconventional rate measures to safeguard broader financial stability.
Point of View
The rupee is sliding, FPI outflows are large, the monsoon has underdelivered, and effective liquidity is tighter than headline figures suggest. Mainstream coverage tends to focus on the rate decision in isolation, but the more significant disclosure is the estimated ₹8.2 lakh crore deposit gap — a structural constraint that could persist well beyond any single rate move. If the RBI does hike and the rupee stabilises, the central bank gains credibility; if it holds and the currency slides further, the cost of that caution will compound quickly.

Frequently Asked Questions
Why is SBI Research recommending a 25 bps rate hike by the RBI?
SBI Research says a combination of rising CPI inflation, a weakening rupee, heavy FPI selling, geopolitical tensions, and crude-price risks has made the case for pre-emptive monetary tightening decisive. The report argues that acting now is preferable to falling behind the inflation curve.
When is the RBI MPC meeting in October 2026?
The RBI's Monetary Policy Committee is scheduled to meet from 5 to 7 October 2026 to deliberate and announce the benchmark repo rate decision.
What is the current CPI inflation rate in India?
CPI inflation rose to 4.82 per cent in August 2026, up from 4.45 per cent in July 2026, according to the SBI Research report, indicating that price pressures are becoming increasingly broad-based.
How does the 2026 monsoon deficit affect the rate hike outlook?
The 2026 monsoon was the fourth driest since 2000, with rainfall at just 87 per cent of the Long Period Average and 43 per cent of districts recording deficient rainfall. Strong El Niño conditions could further suppress October rainfall, threatening Rabi crop output and adding upward pressure on food prices — a key component of CPI.
What is the ₹8.2 lakh crore liquidity gap identified by SBI Research?
SBI Research estimates that despite record forex inflows under a special swap facility, regulatory requirements such as CRR, SLR, and LCR constrain effective liquidity deployment, creating a shortfall of ₹8.2 lakh crore in deposit creation needed to sustain projected 16 per cent credit growth in FY27.
