India's central bank is likely to begin raising its benchmark policy rate as early as December 2026 — pulling forward the timeline from earlier projections of April 2027 — and deliver a cumulative 75 basis points of hikes to anchor the terminal rate at 6 per cent, according to a report by Morgan Stanley released on 6 August 2025. The revised outlook reflects persistently elevated inflation and resilient domestic demand that the investment bank says warrants an earlier monetary tightening response.

Inflation Trajectory Driving the Shift

Morgan Stanley forecasts headline inflation will remain above 5 per cent through June 2027, driven by supply-side pressures and a firming core consumer price index. Core inflation — excluding jewellery — is expected to climb above 4 per cent from November 2026 and hold at or above that level through December 2027. The firm simultaneously projects GDP growth reaching 7 per cent in FY28, a combination that, in its assessment, gives the Reserve Bank of India (RBI) both the reason and the room to act.

RBI's Current Stance and Latest MPC Decision

The RBI's Monetary Policy Committee (MPC) held the policy rate at 5.25 per cent and retained a neutral stance at its most recent meeting. The committee marginally revised its FY27 GDP growth forecast to 6.7 per cent, while projecting headline CPI at 5 per cent and core CPI at 4.3 per cent. The gap between the MPC's own projections and Morgan Stanley's more hawkish inflation outlook is central to the bank's case for an earlier rate-hike cycle.

Capital Flows and the Balance of Payments Outlook

Capital-flow measures announced by the RBI in June have already mobilised approximately $36.7 billion in FCNR(B) deposits, according to the report. Morgan Stanley expects incremental inflows of roughly $70–80 billion, with the bulk of FCNR(B) flows materialising in September 2026. External Commercial Borrowing (ECB)-related inflows are projected to be more back-ended, given that the scheme remains open until December 2026. Collectively, these flows are expected to improve both the composition and durability of capital inflows, resulting in a balance of payments (BoP) surplus of around $35–40 billion in FY2027.

Domestic Demand Signals Supporting Earlier Hike

The rationale for pulling forward the tightening cycle rests partly on high-frequency domestic activity indicators. Consumption data remains healthy: vehicle registrations have sustained double-digit growth since October 2025 across both passenger vehicles and two-wheelers, averaging 26.3 per cent year-on-year and 24.7 per cent year-on-year, respectively. 'Going forward, the consumption outlook remains well supported by upcoming festive and seasonal demand, while rising investment activity is likely to support a broadening capex cycle,' the report noted. These signals, the bank argues, suggest robust underlying demand conditions and a limited impact from supply-side disruptions.

What to Watch Next

Markets and analysts will closely track the RBI MPC's subsequent meetings for any shift in tone from neutral to hawkish, as well as monthly CPI prints through the second half of 2026. If core inflation breaches 4 per cent ahead of schedule, the case for a December 2026 move strengthens further. The path of FCNR(B) deposit inflows in September 2026 will also be a key indicator of whether the capital-flow strategy is delivering the anticipated BoP cushion ahead of any rate action.
