RBI’s New Co-Lending Rules 2026: Big Shift for NBFC and Housing Finance Companies

From 1 January 2026 (or earlier by choice), the Reserve Bank of India (RBI) is introducing a new regulatory framework for co-lending arrangements (CLAs) between regulated entities (REs), like banks, NBFCs, housing finance companies etc. 

The goal is clearer rules around risk sharing, transparency, customer protection, interest rates, disclosure, and operational mechanisms (escrow, reporting, etc.). 

This article explains exactly what changes are coming, how they differ from past practices, what lenders and borrowers must watch for, and what impact may follow.

Background: What are Co-Lending Arrangements & Why Rethink Them?

Co-lending is where two or more regulated financial entities jointly lend to a borrower. Typically one party (“originator RE”) sources the customer, underwrites, does servicing etc., and the other (“co-lender / partner RE”) provides a portion of the funds. Co-lending has been popular for housing loans, MSME loans, consumer finance etc., especially using the NBFC + bank model.

Over time, several risks have emerged, including unclear responsibility for defaults, lack of clarity on who is accountable for customer interactions, ambiguous interest and fee computation, non-uniform reporting, opacity in risk sharing, and insufficient disclosure to borrowers. To address these, RBI has stepped in with revised CLA rules. 

The prior regulatory guidance was less detailed with respect to roles, risk, disclosures etc.; the new rules aim to bring standardization, greater transparency, and stronger customer protection.

Key Provisions of RBI’s New Co-Lending Rules (Effective 1 Jan 2026)

Below are the main provisions introduced, with their practical implications:

• Applicability: The rules apply to commercial banks (excluding small finance banks, regional rural banks, local area banks), all-India financial institutions, non-banking financial companies (NBFCs), and housing finance companies. If digital lending platforms are involved in a co-lending arrangement, they become subject to these rules. Existing CLAs continue under old rules until full implementation.
   
• Minimum Retention by Each Lender: Every lender in a co-lending deal must keep at least 10% of the loan amount on its books. This ensures skin in the game for each participating RE.
   
• Internal Policies, Partner Checks & Borrower Information:
  • REs must include CLAs in their internal credit policy, set internal limits, targets for borrowers, partner institution vetting procedures.
  • Borrowers must be clearly told which institution is their originator RE (the lead), what entity is the partner RE, who to contact, and any changes in that must be communicated in advance. 

Old vs New Rules – What Changes for Lenders & Borrowers

To better understand the shift, here is a comparative table outlining key differences or clarifications introduced by the new rules versus past practice / ambiguity:
 

Implications of the New CLA Rules

These changes are likely to have multiple effects across the banking / NBFC landscape. Here are some of the expected outcomes:

1. Greater Clarity & Borrower Protection
   Borrowers will benefit from clearer communication around who is their lender, what interest and fees apply, and how defaults are handled. This should reduce surprises (hidden costs, misaligned servicing responsibility etc.).
    
2. More Diligent Partner Choice & Risk Management
   Originator REs will likely enhance their due diligence before entering partnership CLAs (on partner RE’s risk profile, past NPA track record etc.), more formal agreements and risk sharing rules.
    
3. Operational Overhead & Compliance Costs
   Maintaining escrow accounts; separate accounting; disclosures; recording in 15 days; ensuring partner REs are suitably compliant—all of these will require process changes, perhaps IT, legal, audit investment.
