RBI Revises Large Exposure Rules for Upper Layer IDF-NBFCs With Immediate Effect

The Reserve Bank of India has revised the large-exposure framework for Infrastructure Debt Fund–Non-Banking Financial Companies (IDF-NBFCs) that are subject to Upper Layer regulation. The change was issued on 25 August 2026 through the Reserve Bank of India (Non-Banking Financial Companies – Concentration Risk Management) Fourth Amendment Directions, 2026 and takes effect immediately.

What RBI changed

The amendment inserts a new paragraph 39A into Chapter IV of the 2025 Concentration Risk Management Directions, the chapter that applies to NBFCs in the Upper Layer. Under the new paragraph, the large-exposure limits applicable to NBFC-Infrastructure Finance Companies (NBFC-IFCs) will also apply to IDF-NBFCs that are subject to Upper Layer regulations.

RBI has linked the new treatment to paragraph 60A of the Reserve Bank of India (Non-Banking Financial Companies – Undertaking of Financial Services) Directions, 2025, read with paragraph 18(4)(i) of the Reserve Bank of India (Commercial Banks – Undertaking of Financial Services) Directions, 2025. The amendment therefore changes the prudential concentration-risk treatment for the specified category of IDF-NBFCs rather than creating a separate stand-alone exposure framework.

Why the amendment matters

Large-exposure rules are intended to limit the concentration of credit or investment exposure to a single counterparty or a connected group. For regulated lenders, these limits feed directly into risk appetite, credit sanctioning, portfolio monitoring, capital planning and compliance reporting. Extending the NBFC-IFC limits to Upper Layer IDF-NBFCs means affected entities should now assess their existing and proposed exposures against the revised framework.

The change is especially relevant for finance and compliance teams because IDF-NBFCs are specialised institutions focused on refinancing infrastructure projects. Infrastructure financing can involve large ticket sizes and concentrated borrower or project-group exposures. A change in the applicable large-exposure ceiling can therefore affect how an IDF-NBFC structures transactions, monitors connected counterparties and escalates limit breaches or near-breaches.

Which entities are covered

The amendment is not framed as a blanket change for every NBFC or every IDF-NBFC. RBI specifically states that the NBFC-IFC large-exposure limits will apply to IDF-NBFCs that are subject to Upper Layer regulations in terms of the referenced provisions. Compliance teams should therefore first confirm the entity's regulatory classification and whether the Upper Layer provisions apply before changing internal limits or controls.

Regulatory context

The underlying Concentration Risk Management Directions were issued on 28 November 2025. The 25 August 2026 measure is the fourth amendment to that framework. RBI says the revision follows a review of the large-exposure framework specifically for IDF-NBFCs in the Upper Layer, signalling a targeted prudential recalibration rather than a wholesale rewrite of NBFC concentration-risk rules.

Immediate compliance points

- Re-map applicable limits: affected IDF-NBFCs should compare their internal large-exposure thresholds with the limits currently applicable to NBFC-IFCs.

- Review outstanding exposures: finance and risk teams should identify single-counterparty and connected-group exposures that may be close to the revised thresholds.

- Update credit and monitoring controls: sanction matrices, concentration dashboards, exception reporting and board or committee reporting may need corresponding changes.

- Check linked RBI directions: the amendment expressly cross-refers to the Undertaking of Financial Services directions for NBFCs and commercial banks, so the classification conditions should be read together rather than in isolation.

- Apply from 25 August 2026: RBI states that the Fourth Amendment Directions come into force with immediate effect.

Reference details

The amendment carries RBI reference RBI/2026-27/237 and DOR.CRE.REC.210/07-03-008/2026-27. It modifies the Reserve Bank of India (Non-Banking Financial Companies – Concentration Risk Management) Directions, 2025 dated 28 November 2025.

For Upper Layer IDF-NBFCs, the key change is straightforward but operationally important: the large-exposure limits used for NBFC-IFCs now apply to them as well. Because the amendment is effective immediately, affected institutions should promptly validate their classification, re-check concentrated exposures and align credit-risk monitoring and governance controls with the revised RBI framework.
