New RBI Loan Rate Rules Explained: End of 'Spread Tinkering' by Banks & NBFCs

The new RBI Loan Rate Rules propose tighter controls on how lenders set and change loan interest rates. The draft aims to make spreads more consistent and transparent across banks, NBFCs and co-operative lenders. The proposed framework could affect floating-rate loans and may apply from April 1, 2027, if finalised.

For years, banks could adjust loan spreads, affecting borrowers even when benchmark rates did not change.  RBI's new rules propose to address such spread tinkering.

The new RBI Loan Rate Rules seek to bring more consistency to this process. The draft framework covers banks and other regulated lenders and focuses on benchmark-linked rates, spread changes and transparency.

• The new RBI Loan Rate Rules are currently a draft, not final regulations.

• The proposed framework aims to standardise how lenders determine loan rates.

• Lenders may face tighter limits on changing spreads during a loan.

• EBLR and MCLR loans use different methods to determine floating interest rates.

• The proposed framework could take effect from April 1, 2027, if finalised.

The new RBI Loan Rate Rules propose a more standardised framework for setting lending rates. The RBI has proposed changes covering benchmark selection, spread adjustments and interest calculation.

Under the draft, lenders would have to follow clearer rules when determining the spread over a benchmark. Reports on the proposal indicate that the spread would generally need to remain unchanged for at least three years, subject to specified conditions.

The proposal is aimed at reducing inconsistent pricing between new and existing borrowers. It also seeks to make loan pricing easier to understand.

Spread tinkering refers to changing the lender's margin over a benchmark, which can alter the final loan rate even when the benchmark itself has not changed.

Suppose a loan has a benchmark of 6% and a spread of 2%. The lending rate would be 8%. If the lender later raises the spread to 2.5%, the rate becomes 8.5%, even if the benchmark remains at 6%.

This is why spread changes matter. A higher rate can increase the interest cost over a long loan tenure. The new RBI Loan Rate Rules seek to place greater discipline around such changes.

EBLR links a loan to an external benchmark, such as the RBI repo rate or another permitted benchmark. Banks then add a spread to determine the lending rate. RBI introduced external benchmark-linked lending for new floating-rate personal and retail loans from October 1, 2019. Banks must reset the benchmark component at least once every three months.

MCLR, or Marginal Cost of Funds-based Lending Rate, is an internal benchmark used by banks. It is based on factors including the bank's marginal cost of funds and operating costs.

The new RBI Loan Rate Rules propose tighter requirements around both systems. For MCLR, the draft also seeks greater consistency in how banks calculate and revise the rate.

The proposed new RBI Loan Rate Rules would extend the framework beyond banks. The draft is intended to cover banks, NBFCs and co-operative lenders, creating a more consistent approach to loan-rate setting.

For banks, the proposal could place clearer limits on spread revisions and MCLR calculations. For NBFCs, it could bring greater standardisation to how floating loan rates and their components are determined.

For borrowers, the main benefit could be improved transparency. A clearer spread structure can make it easier to understand why a loan rate changes.

The proposal does not guarantee lower interest rates. Borrowers would still face changes linked to benchmarks and other permitted factors.

Borrowers can review their loan agreement and identify the benchmark, spread, reset frequency, and conditions for changing the spread. Existing borrowers can also compare their current rate with the terms originally agreed.

The new RBI Loan Rate Rules are still at the draft stage. The RBI has asked for feedback from stakeholders, so the final framework may change. Currently it indicates that the proposed rules could take effect from April 1, 2027.

The new RBI Loan Rate Rules may bring transparency to the loan pricing process, as there will be conditions set out regarding the benchmark and spread of the loan. Nonetheless, the structure mentioned above is a only a proposal. Borrowers need to be aware of their current loan arrangements before considering any changes.

Ans. The new RBI Loan Rate Rules refer to RBI's proposed framework for making loan-rate setting more consistent and transparent. The draft covers benchmark-linked lending, spread changes and related pricing practices across regulated lenders. It is not final yet, so borrowers should wait for the RBI's final directions.

Ans. Spread tinkering refers to adjusting the spread compared with the benchmark rate, which may influence the loan rate. A spread increase will lead to an increased borrowing rate, even with an unchanged benchmark rate. The newly proposed RBI Loan Rate Rules intend to tighten control over such spread changes.

Ans. Not necessarily. The proposed new RBI Loan Rate Rules do not promise lower EMIs or interest rates. A borrower's rate can still change when the applicable benchmark changes. The proposal mainly aims to make rate-setting and spread revisions more consistent and transparent for borrowers.

Ans. The draft framework is intended to cover NBFCs along with banks and co-operative lenders. This could bring greater consistency to how loan rates and spreads are determined across different regulated entities. The exact scope will depend on the final RBI directions issued after the consultation process.

Ans. As per the draft framework, it can come into effect from April 1, 2027, if the current draft remains unchanged after completion. The RBI is open to hearing opinions on the draft. Thus, there may be changes to the final provisions as well as to the enforcement date.
