RBI’s Basel III Credit Risk Framework: What Has Changed?
The Reserve Bank of India has issued the final Capital Charge for Credit Risk (Standardised Approach) Directions, 2026, with effect from April 01, 2027.
At first glance, this may appear to be a routine alignment with Basel III norms. But the changes go beyond technical recalibration. The revised framework reshapes how banks assess credit risk across exposure classes. To understand what this means, it helps to look at what has actually changed.
The Shift Towards Greater Risk Sensitivity
Under the earlier framework, credit exposures were grouped into broader categories with relatively standardised risk weights. The revised Directions move away from this approach.
Instead, they introduce:
- More granular exposure classifications, and
- Differentiated risk weights based on risk characteristics
This allows capital requirements to better reflect the underlying risk profile of each exposure, rather than applying uniform assumptions.
Treatment of Corporate Exposures
One of the more significant changes relates to corporate lending. Risk weights continue to be linked to external credit ratings. However, the treatment of unrated exposures has been tightened.
- Standard unrated exposures: 100% risk weight
- Large exposures (above ₹500 crore): 150% risk weight
This distinction introduces a clear differentiation between rated credit risk and large unrated exposures
Introduction of a Structured Approach to Specialised Lending
A notable change is the introduction of a differentiated framework for specialised lending, including project finance exposures. Risk weights are now linked to the stage and operational and financial performance of the project
In broad terms:
- Pre-operational exposures attract higher risk weights
- Operational projects are treated more favourably
- High-quality, stable projects may benefit from lower capital requirements
This approach reflects a move towards evaluating project risk based on lifecycle and cash flow visibility.
Revised Framework for Real Estate Exposures
The Directions introduce a more detailed framework for real estate exposures, covering both housing and commercial real estate. Risk weights are determined based on factors such as loan-to-value (LTV) ratios, the nature of the exposure, and the source of repayment. In addition, the framework prescribes conditions relating to valuation, monitoring, and underwriting standards.
As a result, real estate exposures are now subject to a more calibrated and risk-sensitive assessment.
Retail and MSME Exposure Treatment
Retail exposures continue to attract relatively lower risk weights, provided they meet specified criteria relating to granularity, ticket size, and borrower profile.
- Qualifying retail exposures: 75% risk weight
- Non-qualifying exposures: higher applicable risk weights
For MSME exposures, the applicable treatment depends on whether the exposure qualifies as retail and whether the borrower is rated. This introduces a tiered structure within MSME lending.
Higher Capital Requirements for Equity and Subordinated Instruments
The Directions prescribe significantly higher risk weights for:
- Equity exposures
- Unlisted and speculative investments
- Subordinated instruments
This reflects the higher risk associated with such exposures and aligns with the broader Basel III framework.
Strengthened Due Diligence Expectations
Banks are required to undertake ongoing due diligence of counterparties and ensure that internal credit assessments are aligned with regulatory risk weight assignments. These assessments must be supported by Board-approved policies and documented processes.
Importantly, due diligence cannot be used to assign a lower risk weight than that implied by external ratings.
Credit Risk Mitigation: Tighter Conditions
While credit risk mitigation techniques such as guarantees and collateral continue to be recognised, their treatment is subject to:
- Strict legal enforceability requirements
- Adjustments for maturity and currency mismatches
Overall Direction of the Framework
Taken together, the Directions indicate a clear shift towards:
- Greater differentiation of risk,
- Closer alignment with actual exposure characteristics, and
- Stronger reliance on structured credit assessment
At the same time, the effectiveness of the framework will depend on how these standards are applied in practice, particularly in areas such as due diligence and project evaluation.
The 2026 Directions represent a comprehensive revision of the Standardised Approach for credit risk. By introducing greater granularity and risk sensitivity, the RBI has moved towards a framework that better captures variations in credit risk across exposure classes.
Key Takeaways for Borrowers and Lenders
For Borrowers: Large unrated borrowings may attract higher capital costs for lenders, particularly where exposure thresholds are crossed. Project structuring, including cash flow visibility and contractual protections, may influence financing terms more directly. Real estate financing may also be subject to tighter evaluation based on LTV and repayment characteristics.
For Lenders: Capital allocation is likely to become more exposure-specific, with greater differentiation across asset classes. Enhanced due diligence and alignment between internal credit assessment and regulatory treatment will be critical. Structuring, documentation, and credit risk mitigation may play a more central role in optimising capital usage.
