RBI’s Policy Pivot: Fighting Inflation Without Sacrificing Growth

 

The Reserve Bank of India’s (RBI) monetary policy decision on 7 October 2026 marks a significant shift in India’s macroeconomic management. By raising the policy repo rate by 25 basis points to 5.50% and adopting a calibrated tightening stance, the Monetary Policy Committee (MPC) has signalled its determination to contain emerging inflationary pressures while safeguarding economic growth. The decision reflects a difficult combination of resilient domestic demand, rising prices and heightened global uncertainty. The central question is whether the RBI can prevent supply-side shocks from becoming persistent inflation without unnecessarily constraining economic activity.

Inflation Returns to Centre Stage

India’s inflation outlook has become increasingly uncertain. The MPC’s October assessment highlighted continuing supply-side pressures arising from a deficient monsoon, ongoing El Niño conditions, and elevated energy and other commodity prices. The pass-through of higher input costs was still continuing, raising concerns about the persistence of inflation.

The RBI projected CPI inflation at 5.2% for FY2026–27, with quarterly inflation estimated at 4.9% in Q2, 6.0% in Q3 and 5.7% in Q4 (Figure 1). Inflation for Q1 of FY2027–28 was projected at 5.6%, with risks assessed as evenly balanced. Core inflation was projected at 4.4% for FY2026–27. These projections indicated that price pressures were expected to intensify during the second half of the financial year.

Subsequent data have reinforced these concerns. CPI inflation rose to 5.54% in September from 4.83% in August, driven largely by food inflation, which climbed to 7.74%. Rural inflation reached 6.08%, compared with 4.88% in urban areas. The broader spread of price increases suggests that inflationary pressures may be extending beyond a limited number of commodities.

Global developments have compounded these risks. The conflict in West Asia and volatility in international crude oil prices threaten to increase India’s import bill, widen the current account deficit and exert pressure on the rupee. Higher energy costs can feed into transportation, manufacturing and distribution expenses, amplifying inflation across the economy.

Growth Remains Resilient, but Risks Persist

India’s real GDP grew by 7.8% in Q1 of FY2026–27, demonstrating the resilience of economic activity. The RBI projected full-year growth at 7.1%, with quarterly growth estimated at 7.2% in Q2, 6.9% in Q3 and 6.8% in Q4 (Figure 2). Growth for Q1 of FY2027–28 was projected at 7.1%, with risks assessed as evenly balanced.

 

These projections point to continued expansion, although growth is expected to moderate from the strong first-quarter performance. Sustaining momentum will depend on private investment, consumption, rural demand and the external environment. Higher interest rates can increase borrowing costs for households and businesses, potentially affecting housing demand, consumer durables, working capital and investment decisions.

The challenge is particularly significant for small and medium enterprises, which often face higher borrowing costs and have limited access to alternative sources of finance. However, allowing inflation to accelerate would also impose costs on growth by eroding real incomes, increasing uncertainty and complicating business planning. Price stability is therefore not an alternative to sustainable growth; it is one of its essential foundations.

Beyond the Repo Rate: Transmission and Liquidity

The effectiveness of monetary policy depends not only on changes in the repo rate but also on how these changes influence lending rates, deposit rates and overall financial conditions. Higher policy rates may gradually raise borrowing costs, while competition for deposits could increase banks’ funding expenses. These developments may influence credit growth and the financial position of borrowers.

Liquidity management will also remain crucial. Adequate liquidity supports orderly financial market conditions, but persistent surplus liquidity can weaken the transmission of a tightening signal. The RBI must calibrate liquidity operations so that short-term money-market rates remain aligned with its intended policy stance without creating unnecessary financial stress.

Exchange-rate movements add another dimension. Higher interest rates may help contain inflationary expectations, but the rupee’s trajectory will also depend on global capital flows, crude oil prices and international risk sentiment. Monetary policy alone cannot offset the effects of a major external supply shock.

The December Policy: Market Expectations and Possible Scenarios

The MPC’s October decision and projections reflected the information available when the policy was announced. The subsequent September inflation figures provide additional evidence that the Committee will need to assess before its December 2026 review.

Market expectations have consequently become an important part of the policy debate. SBI Research Ecowrap (12 October 2026) has projected that CPI inflation could peak at 6.7–6.8% in November and estimated that the policy rate could eventually reach 6.0%. It outlined two possible approaches. Under the first, the RBI could raise the marginal standing facility (MSF) rate by 25 basis points in the intervening period, from 5.75% to 6.0%, followed by a 25-basis-point repo rate increase in December. Under the second, it could opt for a more decisive 50-basis-point repo rate increase in December.

The two approaches imply different degrees of policy urgency. An interim adjustment to the MSF rate followed by a smaller repo increase would represent a more gradual tightening path. A 50-basis-point repo increase in December would send a stronger signal about the RBI’s commitment to price stability. The choice will depend on the persistence and breadth of inflation, the evolution of food and energy prices, the rupee’s trajectory and the strength of domestic demand.

SBI Research’s higher projected inflation peak also highlights the uncertainty surrounding the RBI’s October baseline. The September inflation reading of 5.54% does not by itself establish that further tightening is inevitable. The MPC will need to examine subsequent inflation data, evidence of second-round price effects and the extent to which higher costs are spreading across the consumption basket. If inflation broadens and expectations become less firmly anchored, additional tightening could become more likely. If price pressures ease or growth risks intensify, a more measured response may be justified.

The Way Forward

The December review will test the RBI’s ability to contain persistent inflation without undermining India’s growth momentum. The September inflation increase has strengthened the case for vigilance, but the appropriate response will depend on the persistence of price pressures, exchange-rate developments and the evolving growth outlook. The RBI must remain data-dependent rather than commit prematurely to a particular rate path.

Monetary policy should also be complemented by supply-side measures. Improving agricultural supply chains, strengthening storage and distribution systems, managing food stocks prudently and addressing logistics bottlenecks can help moderate food-price pressures. Greater energy diversification and improved efficiency can reduce vulnerability to external shocks.

Ultimately, the RBI’s task is not to choose between inflation control and economic growth, but to balance the two. A measured policy response, supported by effective fiscal coordination and supply-side reforms, offers the best prospect of anchoring inflation expectations while sustaining investment, employment and India’s broader growth momentum.
