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.
• All CLA details must be disclosed in the key facts statement (the document provided when loan offers are made).
Interest Rate & Fees, Blended Rate: Borrowers will pay a blended interest rate that reflects the share of each lender in the loan. Any other fees (processing, admin, etc.) must be included and clearly disclosed as part of the annual percentage rate (APR). No hidden extras.
Accounting & Disbursal Tracking:
• Each lender must record their portion of the co-lending loan in their books within 15 calendar days of disbursement.
• Separate accounts must be maintained by each lender for their share.
• All funds must flow via an escrow account to ensure proper allocation of amounts between lenders.
Reporting & NPA / Default Treatment:
• Each lender must report their share of the loan to credit information bureaus.
• If one lender treats a loan as non-performing (or stressed), the same classification must apply by the other.
• The originator RE may provide a default loss guarantee of up to 5% of the loan amount.
Transparency & Disclosures:
• Lenders must publish, in their financial statements, their active co-lending partners and details such as size of co-lent loans, interest rates, fees, sectors, performance data.
• All terms to be clear to borrowers.
Loan Transfer to Third Parties: Transfers or assignments of co-lent loans must have mutual consent between originating and partner REs.

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:

Aspect	Old / Previous Practice or Ambiguity	New Rule Under RBI CLA 2026
Lender share retention	Sometimes unclear or negotiated; some lenders might offload large shares immediately / via assignment	Each lender must retain at least 10% of the loan amount on its books
Disclosures to borrower	Borrower might not be clear which entity is the originator vs funder; fees may be opaque	Clear identification of originator / partner, blended rate, full disclosure in key facts statement
Accounting timing	Delay or lack of synchronization between lenders in recording their shares	Each lender must record their share within 15 days of disbursement; separate accounting
Fund flow mechanism	Direct disbursement; sometimes partner RE not involved in servicing; risk in allocation	Disbursement via escrow account to ensure proper allocation and fund flow transparency
Default / NPA treatment	Lender A may classify NPAs, but counterpart may have different view, leading to mismatched risk exposure	If one lender classifies, the other must follow; there is allowance for default loss guarantee up to 5% by originator RE
Reporting & transparency in financials	Co-lending partners or extent not always disclosed in public statements; sector performance data not always transparent	Must disclose co-lending partners, loan book sizes, interest rates, sectors, performance etc. in financial statements

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:

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.).
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.
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.
Standardisation of Contractual Terms
The requirement for blended interest rates, disclosures etc. may lead to more standardised contract templates, industry best practices, which could reduce negotiation friction and legal uncertainties.
Possible Impact on Pricing
Because lenders must keep skin in the game, may face more risk (if partner REs have a higher cost of funds), and must ensure full disclosure, it is possible lending spreads or interest rates in some CLAs may increase slightly to accommodate risk and compliance margins.
Effect on Smaller / Non-Bank Lenders
Smaller NBFCs wanting to be partner REs may face stricter vetting. The originator REs may prefer larger, more credit-worthy partners. Some smaller players might be excluded or have to improve governance / disclosures to participate.
Digital Lending Platforms
Digital lenders if involved in co-lending will be pulled under these rules. That means platforms which aggregate or facilitate finance need to ensure they meet KYC, disclosures, operational, accounting etc. obligations under CLA rules.
Transparency & Investor Confidence
Improved disclosures will help investors, analysts, regulators see which lenders are active in co-lending, how big these exposures are, their performance, helping assess systemic risk and inter-lender credit exposure.

What Borrowers Must Know & Do?

As a borrower or potential borrower via a co-lending scheme, here’s what to check / ask for:

Who is the originating RE and who is the partner RE financing your loan? Which one is your point of contact?
What is the blended interest rate? How is it computed based on the share of each lender? Also, what additional fees or charges are included in the APR?
Make sure to get the Key Facts Statement; examine all disclosures: fees, vendor / partner names, repayment responsibility etc.
Confirm that your lender(s) are compliant with lender KYC, merchant / partner RE credentials; that allocation of funds (if multiple lenders) is correctly captured in your account statements.
Watch for the treatment of default or NPA: whether both lenders will treat delays or non-payment similarly, and whether there’s any default loss guarantee.
Understand your rights: If there's any change in lenders or servicing (e.g. partner RE changes), you should be communicated in advance.

Challenges & Potential Unintended Consequences

While the rules are well-intentioned, certain challenges may arise:

Increased costs: Smaller lenders or NBFCs may struggle with costs of compliance (IT, audit, legal) which could reduce their willingness to engage in co-lending or force higher interest rates.
Underutilization of co-lending: Some originator REs might prefer to lend alone or reduce dependency on co-lenders if partner REs’ terms or risk profile do not align, potentially reducing credit flow to certain segments.
Lag in implementation: Even though rules begin from Jan 2026, shifting existing contracts, systems, disclosures, etc., may take time; there could be friction or delays.
Potential for regulatory overreach or confusion: Parties used to informal arrangements might find new requirements (escrow, blended rate etc.) burdensome; some might try to avoid formal co-lending by using other structures (outsourcing, assignment etc.), possibly creating regulatory arbitrage.
Impact on risk sharing: With strict NPA alignment, partner REs will share default risks; some REs may be more risk-averse in selecting borrowers, which could reduce credit access for higher-risk / niche borrower segments.

Comparison With Co-Lending Practices Elsewhere

To put the RBI CLA 2026 rules in perspective, here are some comparisons with international co-lending / risk-sharing or regulatory practices:

Country / Region	Similar Rules / Co-Lending Practices	Key Differences
USA (Bank + Fintech partnerships)	Fintechs originate loans, banks fund; regulators focus on fair-lending, disclosure, servicing obligations; blended rates disclosure often implicit	US rules vary by state; not always requirement for escrow; sometimes assignment rather than continuous shared risk; default treatment may differ
Europe	Some co-lending or consortium lending models; regulations require transparency, credit risk retention (especially under securitisation rules)	More developed secondary markets; often higher capital requirements; in some cases stronger consumer protection laws (e.g. EU directive)
Other Emerging Markets (South-East Asia, Latin America)	Partnerships between banks, non-bank lenders; shared risk; but regulatory supervision is often less detailed or less enforced; sometimes informal	India’s new rules are quite detailed (escrow, NPA alignment, blended fees etc.), showing higher regulatory rigor especially given fintech / NBFC growth

Conclusion

The RBI’s new Co-Lending Arrangement rules from January 2026 mark a clear step toward improving governance, transparency, and borrower protection in loan partnerships between regulated financial entities. By requiring minimum retention, blended rates, escrow accounts, timely accounting, clear disclosure, and aligned NPA classification, the rules aim to reduce ambiguity and align risk among lenders.

While operational and compliance burdens will increase (especially for smaller players), the benefits, in terms of better borrower information, more standardized processes, and potentially safer credit flows, are substantial. The real test will be how smoothly lenders adapt systems, how transparent the new disclosures are, how borrowers react, and whether credit to underserved segments remains robust under these stricter rules.
