RBI NBFC Concentration Risk Management Directions 2026: Infrastructure Lending and Capital Adequacy Changes

The Reserve Bank of India has issued two rounds of amendments to the Non-Banking Financial Companies Concentration Risk Management Directions in 2026. The first amendment, notified in January 2026, introduced a new classification for high-quality infrastructure projects that receive preferential treatment under concentration norms. The second amendment, notified on 10 March 2026, aligned key capital adequacy definitions with the RBI's updated Prudential Norms on Capital Adequacy Directions, 2025. Together, these amendments reshape how NBFCs assess, report, and manage concentration risk in their lending portfolios, with a particular focus on infrastructure financing. For NBFCs with significant infrastructure exposure, understanding these changes is critical for regulatory compliance and capital planning.

New Category: High-Quality Infrastructure Projects

The first amendment introduces a new classification called high-quality infrastructure projects. Under the existing concentration risk framework, NBFCs are subject to single-borrower and group-borrower exposure limits that cap the proportion of an NBFC's capital that can be lent to any single entity or group of connected entities. Infrastructure lending has traditionally been subject to enhanced exposure limits because of the large ticket sizes involved. The 2026 amendment goes further by creating a distinct sub-category within infrastructure lending that qualifies for preferential treatment. For an infrastructure loan to qualify as high-quality, three conditions must be met simultaneously. First, the project must have completed at least one year of operations after the date of commencement of commercial operations without any breach of material covenants. Second, the exposure must be classified as standard (meaning no default or restructuring). Third, the project revenues must arise from concession or contractual rights granted by the Central or State Government, public sector entities, or statutory or regulatory bodies.

Why the High-Quality Classification Matters for NBFCs

The practical significance of the high-quality classification lies in the higher exposure limits it unlocks. NBFCs that lend to projects meeting all three criteria can take larger exposures to such projects without breaching concentration norms. This is particularly relevant for infrastructure-focused NBFCs that finance road projects under the National Highways Authority of India, power projects with long-term power purchase agreements, port and airport concessions, and urban infrastructure projects backed by municipal or state government contracts. The classification criteria are designed to identify projects where the revenue stream is relatively predictable (government-backed concession), the operational track record is established (at least one year post-commissioning), and the credit quality is sound (standard classification). By restricting the preferential treatment to projects that meet all three conditions, the RBI limits the risk of moral hazard while enabling NBFCs to deploy more capital toward proven infrastructure assets.

Second Amendment: Aligning Capital Definitions with Prudential Norms 2025

The second amendment, notified on 10 March 2026, addresses a technical but important alignment issue. The definitions of Owned Fund and Tier 1 Capital in the Concentration Risk Management Directions have been updated to match the definitions in the RBI's Prudential Norms on Capital Adequacy Directions, 2025. This alignment ensures that NBFCs use the same capital base for calculating both their capital adequacy ratios and their concentration exposure limits. Under the previous framework, it was possible for minor definitional differences between the two sets of directions to produce inconsistent results, where an NBFC might be compliant with concentration norms under one definition of capital but non-compliant under the other. The 2026 amendment eliminates this discrepancy. NBFCs are also now required to obtain an external auditor's certificate on completion of any capital augmentation and submit it to the RBI's Department of Supervision before the additional capital can be reckoned for the purpose of calculating exposure limits.

Implementation Timeline and Transition

The amended directions come into effect from 1 April 2026, or from the date an NBFC chooses to implement the Prudential Norms on Capital Adequacy Amendment Directions, 2026, whichever is earlier. This dual-trigger implementation date gives NBFCs flexibility in their transition planning. An NBFC that has already adopted the 2025 capital adequacy norms can immediately begin applying the aligned concentration risk definitions. Others have until 1 April 2026 to update their systems, policies, and reporting frameworks. The transition period is particularly relevant for mid-sized NBFCs that may need to recalibrate their internal exposure monitoring systems to reflect the updated definitions of Owned Fund and Tier 1 Capital.

Practical Compliance Steps for NBFCs

NBFCs should take several immediate steps to prepare for compliance. First, review the existing infrastructure loan portfolio to identify which exposures meet the three criteria for high-quality infrastructure project classification. Second, update internal credit policies to incorporate the new classification and the enhanced exposure limits it permits. Third, reconcile the definitions of Owned Fund and Tier 1 Capital used in concentration risk calculations with the updated Prudential Norms on Capital Adequacy. Fourth, ensure that any recent capital augmentation has been certified by an external auditor and that the certificate has been submitted to the RBI's Department of Supervision. Fifth, update board-level reporting on concentration risk to reflect the new classification categories and exposure limits. The overall thrust of the 2026 amendments is to create a more nuanced concentration risk framework that differentiates between higher-risk and lower-risk infrastructure lending while bringing capital definitions into alignment across the NBFC regulatory architecture.
