RBI's New NBFC Rule: ₹1 Lakh Crore Asset Size to Define Upper Layer

Introduction to the Proposed Regulatory Shift

The Reserve Bank of India (RBI) has introduced draft amendments that propose a significant overhaul of the regulatory framework for Non-Banking Financial Companies (NBFCs). The central bank aims to simplify the classification of 'Upper Layer' NBFCs (NBFC-UL) by shifting from a complex, multi-parameter scoring system to a straightforward asset-size criterion. Under the proposed 'Reserve Bank of India (Non-Banking Financial Companies' Registration, Exemptions and Framework for Scale Based Regulation) Second Amendment Directions, 2026', any NBFC with an asset size of ₹1 lakh crore or more will be categorized as an NBFC-UL. This move is intended to bring greater transparency, simplicity, and objectivity to the identification process for systemically important financial institutions.

Scrapping the Old Model for a Simpler Approach

The existing Scale-Based Regulation (SBR) framework, introduced in 2022, relied on a two-pronged methodology for identifying NBFC-ULs. This included a parametric scoring model that assigned 70% weightage to quantitative factors like size and leverage, and 30% to qualitative factors such as group structure and liability types. Additionally, the top ten NBFCs by asset size were automatically included in the upper layer. The RBI now proposes to scrap this entire methodology. The draft directions state that the goal is to "adopt a transparent, simple and absolute criteria for identification of NBFC-UL." By replacing the scoring model with a clear monetary threshold, the regulator aims to reduce ambiguity and make the classification process more predictable for all stakeholders.

Key Changes in the Draft Framework

The proposed regulations introduce several fundamental changes. The primary shift is the adoption of the ₹1,00,000 crore asset size as the sole determinant for an NBFC's inclusion in the upper layer. Another critical change is the proposed deletion of the rule that automatically placed the top ten largest NBFCs in this category. This means size alone, above the specified threshold, will be the qualifying factor. Furthermore, the RBI has clarified that the asset-size threshold itself will be subject to a review every five years, ensuring the framework remains relevant as the economy and the financial sector grow. The language is also shifting from "parametric" to "prescribed," signaling a move towards a more rule-based and less interpretive system.

Inclusion of Government-Owned NBFCs

A significant policy shift in the draft is the inclusion of government-owned NBFCs within the scope of the upper layer classification. Previously, these state-run entities were placed only in the base or middle layers, regardless of their size. The RBI's proposal is driven by the principle of an "ownership-neutral regulatory regime." This means that large government-owned NBFCs, which play a systemic role in the economy, will now be subject to the same enhanced regulatory and supervisory standards as their private-sector counterparts if they meet the asset-size criteria. This move is expected to harmonize regulations and ensure that systemic risk is managed consistently across the sector.

The Tata Sons Listing Conundrum

The proposed changes have brought renewed focus on Tata Sons, the unlisted holding company of the Tata conglomerate. Classified as an NBFC-UL in 2023, Tata Sons was required to list on the stock exchanges by October 2025, a deadline it did not meet. The company, with an asset base of ₹1.75 lakh crore as of March 2025, has been seeking to de-register as an NBFC to avoid the mandatory listing. While the new rules simplify the classification, they also reaffirm that Tata Sons comfortably exceeds the ₹1 lakh crore threshold. The market is keenly watching whether the final guidelines will offer any specific exemptions or if the removal of the 'top 10' rule provides any leeway, though on the face of it, the asset-size criterion appears to leave little room for interpretation.

Summary of Old vs. Proposed NBFC-UL Framework

To provide a clear overview, the following table contrasts the key features of the current and proposed regulatory frameworks for identifying Upper Layer NBFCs.

Market Impact and Expert Analysis

Financial sector analysts have largely welcomed the proposed changes for their clarity and simplicity. AM Karthik of ICRA noted that the asset-size criteria will provide certainty to all stakeholders and that including government entities indicates a more harmonized approach. Former SBI chairperson DH Kar agreed that the new process is simpler and correctly focuses on balance sheet size as the primary indicator of systemic risk. The move is expected to increase the number of entities in the NBFC-UL list, subjecting more large players to stricter oversight. The draft also proposes allowing all NBFC-ULs to use state government guarantees as a credit risk transfer instrument without limits, which could enhance their lending capacity.

Next Steps and Conclusion

The RBI has invited public comments on the draft directions until May 4, 2026, after which it will issue the final guidelines. The outcome will be crucial for the entire NBFC sector, particularly for large entities nearing the ₹1 lakh crore mark. For Tata Sons, the final rules will provide a decisive answer to the long-standing question of its mandatory public listing. The proposed framework represents a significant step towards a more streamlined, transparent, and risk-focused regulatory environment for India's largest non-banking financial companies.
