The Reserve Bank of India raised its benchmark repo rate by 25 basis points to 5.5% on Wednesday, its first increase since February 2023, as rising inflation risks, higher crude oil prices and global financial pressures prompted the central bank to shift towards tighter monetary policy.

The Monetary Policy Committee (MPC) unanimously raised the repo rate from 5.25% and changed its policy stance from neutral to “calibrated tightening”, signalling that the RBI is prepared to respond further if inflationary pressures continue to build.

The decision marks a significant change after a prolonged period in which the RBI had kept borrowing costs unchanged while supporting economic growth. The latest move comes as the economy remains relatively strong but faces a more difficult external environment, particularly from elevated oil prices, a weaker rupee and tighter global financial conditions.

The RBI’s decision also comes after retail inflation rose to 4.82% in August from 4.45% in July, moving further above the central bank’s 4% medium-term target. The combination of higher commodity prices and risks of broader price pressures has increased concerns that inflation could remain elevated in the coming quarters.

Inflation, oil prices force policy recalibration

Higher crude oil prices have emerged as one of the biggest risks to India’s inflation outlook. Brent crude has traded above $100 a barrel amid disruptions and uncertainty linked to the conflict involving Iran, raising concerns about India’s import bill and the cost of fuel, transport and other inputs.

The impact extends beyond fuel. Higher energy and commodity costs can raise production and transportation expenses for businesses and eventually feed into consumer prices.

The RBI has therefore faced a difficult policy trade-off. Keeping rates unchanged would continue to support borrowing and investment, but allowing inflation expectations to become entrenched could make it harder to bring inflation back towards the 4% target.

The central bank raised its FY27 inflation projection to 5.2%, from 5% previously, according to reports on the policy decision. The RBI is also reported to expect headline inflation to remain elevated in the near term before easing as some supply pressures moderate.

The shift to calibrated tightening gives the RBI greater flexibility to raise rates further if inflation remains persistent. At the same time, the language does not automatically commit the central bank to a prolonged series of increases, leaving future decisions dependent on incoming inflation, growth and financial-market data.

The rate increase could raise borrowing costs for households and businesses, particularly for loans linked to external benchmarks. Banks could pass on the increase through higher lending rates, potentially raising EMIs for home, vehicle and other floating-rate loans.

Deposit rates could also move higher as banks seek to attract funds, potentially benefiting savers.

Strong growth gives RBI room to focus on prices

The RBI’s decision comes despite continued strength in the domestic economy.

India’s economy expanded 7.8% in the June quarter, providing the central bank with greater room to prioritise price stability rather than maintaining exceptionally accommodative monetary conditions. The RBI has also raised its FY27 growth projection to 7.1% from 6.7%, according to reports following the policy announcement.

The stronger growth performance reduces the immediate risk that a moderate rate increase will cause a sharp slowdown.

However, the outlook is not without risks. Higher crude prices can simultaneously weaken growth and increase inflation by raising input costs and reducing consumers’ purchasing power.

Global financial conditions are another concern. US Treasury yields have risen sharply, while the dollar has remained firm, putting pressure on emerging-market currencies.

The rupee fell to around 96.42 against the dollar on Tuesday, a two-month low, as foreign investors continued to withdraw money from Indian equities and oil prices remained elevated.

A weaker rupee makes imported goods and commodities more expensive, adding another channel through which global price pressures can reach the Indian economy.

Liquidity, rupee remain key policy challenges

The RBI’s policy response is not limited to the repo rate. Managing excess liquidity in the banking system has become an increasingly important part of monetary policy.

System liquidity had surged earlier in September, prompting the RBI to use tools including open market operations, variable-rate reverse repo operations and foreign-exchange transactions to absorb excess funds.

Liquidity surplus had fallen substantially from the levels seen earlier in September, although the banking system continued to carry a sizeable surplus. According to recent data cited ahead of the policy decision, the liquidity surplus stood at around Rs 5 lakh crore on October 6.

The RBI’s challenge is to prevent surplus liquidity from weakening the transmission of tighter monetary policy while avoiding excessive tightening that could disrupt credit conditions.

The central bank has also been using foreign-exchange operations to manage volatility in the rupee. Reuters reported that the RBI has deployed dollar-rupee swaps, bond sales and other tools while dealing with excess liquidity and currency pressures.

The currency remains particularly vulnerable because India is heavily dependent on imported crude oil. A sustained rise in oil prices can widen the trade deficit, increase demand for dollars and put additional pressure on the rupee.

Markets look for signals on further rate hikes

For financial markets, the 25-basis-point increase itself was largely anticipated. The bigger question is how far the RBI is prepared to go if inflation remains above target.

The shift to calibrated tightening suggests that the central bank is no longer treating the current inflation increase as a temporary development that can simply be ignored while growth remains strong.

Market participants will therefore closely watch the RBI’s assessment of core inflation, crude prices, the rupee, global bond yields and domestic demand.

A prolonged tightening cycle could raise borrowing costs for companies and households and eventually slow credit growth. Banks could benefit from higher lending yields initially, but a sustained increase in funding costs could pressure margins and loan demand.

Government bond yields are also likely to remain sensitive to expectations about the future rate path. Higher rates can increase the cost of government borrowing and influence valuations across debt and equity markets.

For the equity market, the policy creates a more complicated environment. Strong economic growth remains supportive for corporate earnings, but higher interest rates, elevated oil prices, foreign outflows and currency weakness could limit the upside.

The RBI’s immediate task is therefore to prevent a supply-driven inflation shock from becoming entrenched while preserving the underlying momentum in the economy.

The first rate increase in more than three years marks a clear change in policy direction. Whether it develops into a sustained tightening cycle will depend largely on the trajectory of inflation, oil prices and the rupee in the months ahead.
