RBI proposes new MCLR formula on 3-month moving average
Banks lend people money, and the interest they charge depends partly on what it costs the bank to get money in the first place.
In India, the central bank called the RBI makes rules to keep this fair and clear.
Right now, the RBI has suggested a new way for banks to work out that cost.
Instead of looking at just one moment, banks would look at the average cost of new deposits and borrowings over the past three months.
The RBI also wants this information to come automatically from the bank's systems so it can be checked easily.
This is part of a bigger plan to make loan pricing more transparent.
Banks would have to set floating loan rates using a benchmark plus a spread that reflects risk and costs.
The spread's risk part could never be negative, and it could only change if the borrower's credit situation changes.
The new rules would likely start in April 2027, and older loans would need to switch over by April 2029.
All of this is meant to help borrowers understand how their interest rates are set and changed.
The RBI has proposed a new MCLR formula based on a three-month moving average of banks' marginal funding costs.
Banks would calculate MCLR using the marginal cost of domestic deposits and borrowings, with data that is system-generated and independently verifiable.
The draft also proposes that floating-rate loans be linked to an internal or external benchmark plus a risk-based spread, with reset periods not exceeding three months.
Under the proposal, the credit risk premium component of the spread must remain positive and be revised only when a borrower's credit profile changes.
The new framework, proposed under the draft Reserve Bank of India (Interest Rates on Loans and Advances) Directions, 2026, is proposed to take effect from April 1, 2027, with existing benchmark-linked loans migrated by April 1, 2029.
- Who
- The Reserve Bank of India (RBI)
- What
- Proposed a new MCLR formula based on a three-month moving average of funding costs, along with wider loan pricing rules including benchmark-linked floating rates, shorter resets, and spread discipline
- Where
- India
- When
- Draft proposal announced now; framework proposed to take effect from April 1, 2027, with migration of existing loans by April 1, 2029
- Why
- To make loan pricing more transparent and consistent across lenders and give borrowers greater clarity on how interest rates are determined and revised
Consumer Transparency Perspective
Lender Operational Perspective
Frequency of rate resets
Consumer Transparency Perspective
Shorter reset periods of up to three months mean changes in benchmark rates are reflected in loan EMIs more frequently, giving borrowers faster benefit when rates fall.
Lender Operational Perspective
More frequent resets create operational complexity for banks in recalculating and communicating rates, and expose borrowers to quicker increases when rates rise.
Standardized spread discipline
Consumer Transparency Perspective
Requiring the credit risk premium to stay positive and change only with the borrower's credit profile protects borrowers from arbitrary or opaque spread increases.
Lender Operational Perspective
Restricting when spreads can be revised may limit banks' flexibility to price loans according to evolving business costs and risk conditions.
