The Reserve Bank of India's (RBI) recent decision to raise the repo rate to 5.50% marks the beginning of a potentially more aggressive monetary tightening cycle, with SBI Research forecasting the policy rate could reach 6% by December 2026. This projection, detailed in SBI Research's latest Ecowrap report, is largely driven by an anticipated worsening of India’s inflation trajectory.
RBI's Policy Shift and Inflation Outlook
On October 7, the Monetary Policy Committee (MPC) unanimously voted to increase the repo rate by 25 basis points to 5.50%, marking the first rate hike in approximately four years. Alongside this, the MPC shifted its policy stance from neutral to 'calibrated tightening,' a decision supported by a 4-2 majority.
According to SBI Research, this policy shift represents a significant change in the RBI's approach. The central bank's near-term options have narrowed, with further rate hikes or a pause being the only viable paths, as rate cuts are currently off the table. The research firm estimates that India's Consumer Price Index (CPI) inflation could peak at around 6.8% in November 2026, prompting the need for a more forceful response from the central bank.
Why Inflation is Forcing the RBI's Hand
The RBI has already revised its inflation forecasts for FY27, raising the CPI inflation projection by 20 basis points to 5.2% and the core inflation projection by 10 basis points to 4.4%. Quarterly inflation expectations stand at 4.9% for Q2, 6% for Q3, and 5.7% for Q4 of FY27.
SBI Research's historical analysis indicates a strong correlation between the intensity and persistence of inflationary pressures and the RBI's peak policy rate. Given the potential for inflation to reach 6.8% in November, a 6% peak repo rate would align with historical patterns, suggesting the RBI is prioritizing price stability.
Future Monetary Policy Trajectory
The research team suggests that the December policy meeting could see a further 50 basis points hike, contingent on global economic conditions. They argue that the RBI might opt for a larger, decisive move rather than a series of smaller increases, especially if global volatility intensifies, to enhance effectiveness.
Despite the focus on inflation, the RBI has not abandoned its growth outlook. It raised its FY27 GDP growth forecast by 40 basis points to 7.1%, citing sustained momentum in services, robust capacity utilization, and strong credit flows. This combination of stronger growth and rising inflation provides the RBI with more room to focus on curbing prices through higher interest rates.
The current policy shift is described as a move from 'watchfulness to explicit tightening,' rather than a panic reaction. If inflation follows SBI’s projected trajectory, India’s monetary policy is set to become significantly more restrictive, with a 6% repo rate becoming a distinct possibility as early as December.
