RBI raises the repo rate to 5.50%: when does a loan become costlier?

The Reserve Bank of India raised the repo rate by 0.25 percentage points to 5.50% on 7 October 2026. All six members of its Monetary Policy Committee supported the increase. For someone repaying a floating-rate home loan, the next important date is the loan’s interest-rate reset: that is when a change in its benchmark can affect the loan’s interest rate and repayments.

The repo rate is the interest rate at which the RBI lends short-term funds to banks against securities. It also serves as a reference for many bank loans. A higher repo rate can therefore affect a household without that household ever borrowing directly from the central bank.

Why raise rates when food and oil are expensive?

The RBI’s concern is that an initial supply shock can spread. Costlier fuel raises transport and production expenses; businesses may raise selling prices. If households and firms expect prices to keep rising, those expectations can influence wages, purchases and further price-setting.

In its 7 October assessment, the RBI described limited signs that price pressures were becoming embedded. It also noted risks from strong growth in money and credit, despite limited evidence of demand pressures. It judged economic growth resilient enough to support tighter policy. Raising borrowing costs can restrain spending and credit growth, helping limit the spread of inflation. It cannot produce more oil or improve a harvest, and the cost of restraint falls partly on borrowers and businesses seeking finance.

The committee adopted a stance of “calibrated tightening”, which it said currently allows a pause or a further increase. The rate decision was unanimous; two members preferred a neutral stance. Its resolution leaves the future path dependent on economic conditions.

From the repo rate to the loan rate

A floating loan’s interest rate has two main parts: a benchmark, the reference rate that can change, and a spread, the lender’s addition to that reference. The repo rate is one permitted external benchmark. Other loans use different references, including a bank’s marginal cost of funds based lending rate, or MCLR.

Suppose a repo-linked loan carries an unchanged spread of three percentage points. Before this decision, its rate would be 5.25% + 3% = 8.25%. After the benchmark increase reaches the loan’s reset, it would be 5.50% + 3% = 8.50%. These are teaching numbers, not a quoted bank product. A 0.25-percentage-point rise is often called 25 basis points.

The contract matters because the RBI’s announcement and a borrower’s reset are separate events. Under the RBI’s current bank lending directions, new floating personal and retail loans from the specified banks have used external benchmarks since October 2019. External-benchmark loan rates must reset at least once every three months. MCLR-linked loans follow their contractual reset period, which must be one year or less. Older loans, different lender types and fixed-rate contracts can follow different arrangements.

A borrower should therefore read the benchmark name and next reset date together. A fixed-rate loan follows its agreed fixed-rate terms; a floating loan changes according to its benchmark and contract.

A higher EMI, a longer loan, or both

An equated monthly instalment, or EMI, pays interest and gradually repays the outstanding loan balance. When the interest rate rises, keeping the same balance and repayment period requires a higher EMI. Keeping the EMI down generally means taking longer to repay.

For a worked example, suppose ₹30 lakh remains outstanding, with 20 years left, and the loan uses standard monthly amortisation. If the annual rate rises from 8.25% to 8.50% and the repayment period stays at 240 months, the approximate figures are:

The calculation uses monthly interest equal to the annual rate divided by 12. Actual repayments depend on the loan’s terms and the lender’s calculation. The example shows why a small change in the benchmark can matter over a large outstanding balance.

Extending the loan instead reduces the immediate increase in monthly payments, but means paying interest for longer if other assumptions stay the same. An unchanged EMI can therefore conceal a growing repayment period.

What information and choices must the lender provide?

For covered floating-rate personal loans repaid through equated instalments, the RBI’s current FAQ requires lenders to communicate increases in EMI or repayment period. Borrowers must be offered a higher EMI, a longer repayment period, or a combination, and the option of part or full prepayment under the applicable rules. Quarterly statements must show repayment information, including the EMI, remaining instalments and annualised interest rate.

A fixed-rate switch depends on the lender’s policy. The RBI’s September 2025 amendment, effective 1 October 2025, made offering that switch optional for lenders. Borrowers should check whether their lender offers it and what charges or terms apply.

After this week’s decision, three details explain a floating loan’s next change: its benchmark, its next reset date and its revised repayment schedule. Together they show whether the rate rise increases the monthly payment, extends the loan, or both.
