The RBI rate outlook from SBI Research continues to point to 50 basis points of tightening in December 2026, citing broader inflation pressures and elevated crude oil prices. Its assessment, published ahead of October 22, outlines either a straightforward repo rate increase or a smaller increase combined with a change to the central bank’s liquidity corridor. Neither option is an announced Reserve Bank of India decision.
Key Takeaways
- SBI Research retains its December tightening forecast, with two possible policy configurations.
- The RBI’s October decision leaves a rate increase or a pause on the table, rather than committing to another hike.
- Broader price pressures and oil costs underpin SBI Research’s inflation concerns.

RBI rate outlook includes two December options
SBI Research’s first scenario is a 50-basis-point repo rate increase, taking the benchmark from 5.50% to 6.00%. Its alternative combines a 25-basis-point repo increase to 5.75% with an asymmetric widening of the liquidity adjustment facility, or LAF, corridor.
Under the second scenario, SBI Research puts the marginal standing facility rate at 6.25% and the standing deposit facility rate at 5.50%. It said this configuration could help maintain orderly market functioning amid global uncertainty.
The distinction matters: SBI Research’s 50-basis-point tightening call does not necessarily mean a half-percentage-point increase in the repo rate itself. Its alternative would also change the relationship between the RBI’s lending and deposit facilities.
| Item | Details |
|---|---|
| October standing deposit facility rate | 5.25% following the MPC decision. |
| October marginal standing facility rate | 5.75% following the MPC decision. |
| RBI full-year inflation projection | 5.2% for FY2026–27. |
| RBI real GDP growth projection | 7.1% for FY2026–27. |
October decision leaves room for a pause
The RBI’s October MPC minutes confirm that policymakers unanimously raised the repo rate by 25 basis points to 5.50% at their October 5–7, 2026 meeting. The committee also changed its policy stance to calibrated tightening, although two members preferred to retain a neutral stance.
The RBI said near-term rate cuts were off the table under current conditions, leaving either an increase or a pause dependent on economic developments. The duration and extent of tightening would depend on underlying inflation, the spread of price pressures, supply-shock effects and demand conditions.
That conditional position is narrower than a commitment to SBI Research’s December forecast. The central bank has not announced the size or direction of its next rate decision.
Inflation breadth and oil underpin the forecast
SBI Research said the number of commodities accounting for 75% of the Consumer Price Index’s weighted contribution increased from 25 in August to 31 in September. It interpreted this as evidence that inflation pressures had spread across more items.
The research team expects inflation to peak below 6.5% in November. It also projects dated Brent crude prices to average $110 per barrel over a 15-day forecast period; that is a forecast, not an observed average.
The RBI separately projects headline retail inflation of 6.0% in the third quarter of FY2026–27, easing to 5.7% in the fourth quarter.
Conclusion
The next confirmed policy checkpoint is the MPC meeting on December 2–4, 2026. Policymakers will reassess inflation and growth conditions before deciding whether to raise rates again or pause.
