# Co-Lending Model: How Banks and NBFCs Share Loans

India's credit demand vastly exceeds what any single lender can profitably serve. Banks have cheap deposits but conservative risk appetite; NBFCs have distribution and underwriting agility but expensive funding. The Reserve Bank of India's co-lending framework is designed to make these two collaborate — sharing both the loan and the economics on a single borrower's books.

What Is Co-Lending?

Under co-lending (earlier called co-origination), a bank and an NBFC enter into a prior arrangement to jointly lend to a priority-sector or other target borrower. Key features:

  • A single loan agreement with the borrower, jointly executed
  • The loan appears on both lenders' books in their respective shares — it is not lending by one to the other
  • Terms are common for the borrower; each lender funds its share at its own cost
  • Interest to the borrower is typically a blended rate reflecting both lenders' funding costs

The RBI first permitted co-origination for priority sector lending in 2018 and expanded and liberalised the framework in 2020, opening it to all eligible loans and allowing NBFCs beyond HFCs to participate.

The 80:20 Structure

Minimum retention rules

The framework prescribes minimum holding requirements:

  • The NBFC must retain at least 10% of its share of the loan on its books until maturity (i.e., if funding 20%, it must keep at least 2% of the total exposure)
  • The bank's role as senior funder means it typically takes the larger share — commonly 80% — while the NBFC takes 20%

This "skin in the game" rule prevents co-lending from becoming a disguised origination-and-transfer arrangement where the NBFC offloads all risk immediately.

Blended pricing in practice

If a bank can fund at 8% and the NBFC's cost of funds is 12%, a blended rate might land near 9–10% for the borrower — cheaper than pure NBFC credit, more flexible than standard bank underwriting. The NBFC often earns additional income through servicing fees.

Why Co-Lending Has Grown

For banks

  • Access to segments and geographies they can't underwrite efficiently themselves
  • Priority sector lending targets can be met through qualified portfolios
  • Lower acquisition costs by leveraging partner distribution

For NBFCs

  • Dramatically lower cost of funds versus their own borrowings
  • Ability to scale book size without proportionate capital
  • Balance-sheet-light growth that preserves return on equity

For fintechs

Digital lending platforms increasingly sit inside co-lending arrangements as technology partners or licensed NBFCs, providing origination, underwriting data, and servicing while banks provide most of the capital. It has become the dominant structure for scaling compliant digital credit in India.

Operational Mechanics

Running a co-lending book requires real infrastructure:

  1. Joint documentation: one master facility agreement plus a co-lending agreement defining shares, decision rights, and exit terms
  2. Shared systems: a common loan management system tracking each lender's entitlement to every EMI
  3. Escrow and reconciliation: repayments flow into escrow accounts and are split per agreed ratios
  4. Reporting: each lender reports its share in its own regulatory returns; misreporting attracts supervisory action
  5. Default handling: recovery responsibilities, DLG arrangements (capped at 5% under digital lending rules), and write-off policies must be pre-agreed

    6. Common Pitfalls

    • Blurred accountability: when both lenders think the other monitors the portfolio, early-warning signals get missed. Good agreements assign explicit monitoring duties.
    • Pricing disputes: blended-rate math must be locked upfront; renegotiating mid-cycle damages borrower trust.
    • Regulatory drift: RBI expectations on outsourcing, digital lending conduct, and fair practices apply fully to co-lending books — partners sometimes assume otherwise.

    Co-Lending in the Real Economy

    The model works best when the originating partner brings something the bank lacks — like verified transaction data. B2B financing platforms show this clearly: KredFlow, operating through RBI-compliant structures, uses GSTIN-based verification to approve businesses financing software purchases, letting buyers pay annual SaaS contracts monthly while vendors receive payment upfront. In such arrangements, a bank co-funds a portfolio whose credit quality rests on real invoices rather than unsecured consumer scores — exactly the kind of asset co-lending was designed to unlock.

    The Bottom Line

    Co-lending aligns India's cheapest capital with its most agile underwriters, under a structure the RBI has deliberately kept simple: shared loans, minimum retention, blended pricing. For fintechs, it's the natural next step after the LSP model — deeper integration, better economics, and genuine skin in the game.
