New RBI Rule: How Co-Lending Changes What You Pay on a Personal Loan in 2026
By Nitish Bharadwaj · Published Jul 5, 2026 · 6 min
Many personal loans sold through fintech apps are actually funded jointly by a bank and an NBFC under a co-lending arrangement — and until now, borrowers rarely saw how the two lenders' rates combined into what they were charged. RBI's Co-Lending Arrangements Directions, effective January 1, 2026, require a single disclosed blended interest rate (a funding-share-weighted average of both rates), a mandatory 10% minimum retention on each lender's books, escrow-routed repayments, and one point of contact for servicing. This guide walks through a worked blended-rate example and what to verify before signing.
Applied for a personal loan through a lending app and noticed the sanction letter names two lenders — say, a bank and an NBFC — instead of one? That's not a paperwork error. It's co-lending, a model where a bank and an NBFC jointly fund your loan, and from January 1, 2026, RBI's Co-Lending Arrangements Directions change what you're allowed to be charged and how clearly it must be disclosed.
What Is Co-Lending, and Why Your Personal Loan Might Have Two Lenders
Many personal loans distributed through fintech apps aren't funded by a single institution. Under a co-lending arrangement, a bank and an NBFC (often the fintech's own lending arm) jointly fund the same loan, typically because the NBFC brings the digital reach and underwriting model while the bank brings lower-cost capital. Until now, borrowers rarely saw how the two lenders' individual rates combined into what they were actually charged — the pricing was often opaque, and it wasn't always clear who to approach if something went wrong with servicing.
The Blended Rate Rule: How the January 2026 Directions Change Your Cost
RBI's Co-Lending Arrangements Directions, 2025, effective from January 1, 2026, require that a co-lent loan carry a single, disclosed blended interest rate — a weighted average of each lender's own rate, weighted by how much of the loan each one is funding. You no longer have to work out (or guess at) how a bank's rate and an NBFC's rate combine; the sanction letter must show you the one number you'll actually pay.
| Lender | Share of Loan Funded | Own Interest Rate | Contribution to Blended Rate |
|---|---|---|---|
| Bank | 20% | 11% p.a. | 0.20 × 11% = 2.2% |
| NBFC | 80% | 16% p.a. | 0.80 × 16% = 12.8% |
| Blended rate charged to borrower | 100% | — | 2.2% + 12.8% = 15% p.a. |
In this example, even though the bank's own rate is 11%, the borrower pays 15% because the NBFC — funding the larger 80% share, and typically pricing for a riskier or thinner-file borrower segment — pulls the blended number up. The rate itself isn't new; what's new is that the funding split and the resulting blended figure must now be disclosed to you rather than left implicit in a single quoted APR.
Other Protections the New Directions Add
- The bank must retain a minimum 20% share of the loan on its own books (with the NBFC funding the remaining 80%), so both institutions carry real skin in the game rather than one acting purely as a pass-through originator.
- Loan disbursements and repayments must be routed through an escrow account, and each lender must record its share of the loan in its own books within 15 calendar days of disbursement.
- You get a single point of contact for servicing and complaints, even though two institutions are funding the loan behind the scenes.
- Loan documents must be standardised and clearly identify both lenders, their respective shares, and the blended rate — not just the fintech app's brand name on the front screen.
What to Check Before You Sign a Co-Lent Personal Loan
Ask the lending app to name both institutions funding the loan and their individual funding shares, then verify the blended rate in your sanction letter matches that split using the weighted-average method above. Before accepting, run the EMI on the disclosed blended rate through the EMI calculator and compare it against a straight bank personal loan quote — our HDFC vs SBI vs Axis personal loan comparison is a useful benchmark. A co-lending structure isn't automatically worse than a single-lender loan, but the new disclosure rules exist precisely so you can compare it on equal footing instead of taking the headline rate on faith.
