RBI Seen Starting a Rate-Hike Cycle: Why Banks Expect the Repo Rate to Reach 6% by March 2027
Reports by two banks, Union Bank of India and ICICI Bank, expect the Reserve Bank of India (RBI) to start a rate-hike cycle (a series of interest rate increases spread over several meetings) at its October 5 to 7, 2026 policy meeting.
Both banks see a total increase of 75 basis points (0.75 percentage points). This would take the repo rate from 5.25% to about 6% by the end of FY27 (March 2027). Union Bank expects the first step to be a 25 basis point hike to 5.50%.
ICICI Bank raised its forecast of retail inflation (CPI) for FY27 to 5.1% from 5%. It expects inflation to peak at about 5.9% in the third quarter of FY27 (October to December 2026) and notes that core inflation (inflation without food and fuel) is also rising.
Union Bank expects FY27 inflation of about 5.4%, staying above 6% in the second half of the year. It points to a weak (deficient) monsoon and crude oil near $100 a barrel as the main pressures.
ICICI Bank says the hikes could stop at 50 basis points if global energy prices fall sharply, but could stretch to 100 to 125 basis points if the oil shock lasts. It expects the RBI to keep a neutral, data-dependent stance because of global uncertainty.
A 75 basis point cycle would keep the real interest rate (the repo rate minus expected inflation) in a range of about 1.4% to 1.9%, according to ICICI Bank.
Imported Inflation: How Global Prices and a Weak Rupee Raise Prices at Home
Imported inflation is a rise in prices inside a country that comes from outside the country. It happens when the things a country buys from abroad become costlier, either because their world price goes up or because the country's own currency becomes weaker. For India, the biggest example is crude oil: when oil becomes costly abroad, petrol, diesel, transport and many other things become costly at home. So Indian families pay more even though nothing changed inside India.
Both bank reports name crude oil near $100 a barrel and a weak rupee as key reasons why inflation is rising and why the RBI may begin hiking rates. This is imported inflation at work. ICICI Bank's warning that core inflation is also rising shows the worry that the oil shock is spreading into the wider economy, which is exactly the stage at which central banks step in with rate hikes.
Flexible Inflation Targeting (FIT) Framework
Flexible Inflation Targeting is the system under which the RBI's main job is to keep retail inflation close to a target fixed by the central government. The target is 4%, measured by the Consumer Price Index (CPI), with a band of 2% to 6%. It is "flexible" because the RBI may also keep economic growth in mind while bringing inflation back to the target. The framework got legal backing through the Finance Act, 2016, which amended the RBI Act, 1934.
Retail inflation was 4.82% in August 2026, above the 4% target for a third straight month, and banks expect it to approach 6% later in FY27. Under FIT, the RBI must act before inflation breaks the 6% upper limit. ICICI Bank's estimate that a 75 basis point cycle keeps the real interest rate at 1.4% to 1.9% shows how the framework guides the size of rate hikes.
Exchange Rate Management in India: RBI's Managed Float
India's exchange rate is mostly set by the market, through the demand for and supply of dollars. But the RBI steps in when the rupee moves too sharply, by buying or selling dollars from its foreign exchange reserves. This mix is called a managed float. The RBI says it does not target any particular level of the rupee; it only tries to smooth out sudden, disorderly swings.
The bank reports list a weak rupee alongside costly crude as a reason for raising rates. A rate hike can also support the rupee, because higher Indian interest rates make it more attractive for foreign investors to keep money in India. So the RBI's rate decision and its rupee management work together.
