IDFC First Bank is a universal bank built by merging a corporate lender with a consumer-finance specialist, then methodically replacing wholesale loans with retail deposits and small-ticket lending. The merger of IDFC Bank and Capital First in 2018 gave the new entity a banking licence and a cost of funds that fell from roughly 12-13% to about 6%, while the acquired retail-underwriting engine - refined over 15 years of cash-flow lending to salons, chemists and kirana stores - was scaled across more than 25 product lines. The recurring approach is a customer-first product test: every offering must pass a “Near and Dear” standard, meaning employees would recommend it to their own families, which is how the bank became the first universal bank to credit savings interest monthly, issue lifetime-free credit cards with never-expiring rewards, and eliminate fees on 28 essential savings-account services.
Business segments
Four engines at different stages - a retail-lending machine that earns the spread, a deposit franchise that funds it, a credit-card platform that deepens customer relationships, and a wholesale book that has been deliberately shrunk and derisked - each built on the cash-flow underwriting and technology backbone of the original NBFC.
1. Retail, rural and MSME lending: the engine that makes the money
A diversified book of secured and unsecured loans to individuals, micro-entrepreneurs and small businesses, underwritten by reading a borrower’s bank statement rather than relying on collateral alone, and priced to deliver a risk-adjusted yield above 11% after credit costs.
- Cash-flow, not just collateral - the bank evaluates a customer’s bank statement, GST filings and bureau data to size repayment capacity, then takes an auto-debit instruction from that same account, which management calls “practically working as an escrow”. Applications pass through a 10-step filter - deduplication, bureau checks, risk scorecards, banking-statement analysis, personal discussion, fraud checks and more - and 40-60% are rejected depending on the product.
- Spread across 25 lines so no single segment dominates - no product exceeds 15% of the loan book. As of March 2026 the mix was mortgage-backed 28%, other retail 26%, wholesale 20%, vehicle 12%, MSME 8% and rural 6%, with unsecured retail credit at 14% of the total book.
- Tested through six crises with credit costs around 2% - over 15 years the RAM book has absorbed economic slowdown, demonetisation, GST, the IL&FS crisis, COVID-19 and an MFI crisis while keeping gross NPA around 2% and net NPA around 1%, the only exception being the COVID period. Over the five-year block FY21-FY25, credit cost averaged 1.95% including both COVID and the MFI shock.
- Acquires customers through durable-goods financing - the consumer-durable vertical, built with over 100 top-tier brands (Apple, Samsung, LG and others) and nearly one lakh dealers, serves more than 2.7 crore customers and sees 45% of monthly disbursals from repeat borrowers, making it the largest acquisition engine on the retail-asset side.
- Rural reach through a dedicated subsidiary - IDFC First Bharat Limited, a wholly owned corporate business correspondent, operates 637 branches and sourced loans worth Rs. 10,984 crore during FY25, supporting over 8.5 million rural customers and 53 lakh active women borrowers under the Sakhi Shakti programme.
2. Deposits and retail liabilities: the funding engine that is still being built
A granular deposit franchise grown from an 8.68% CASA ratio at merger to roughly 50% today, deliberately kept loss-making while the bank invests in branches, technology and brand trust.
- From institutional to retail in seven years - at merger, retail deposits were just 8% of total liabilities; by March 2026 customer deposits stood at Rs. 284,453 crore with CASA at 49.8% on an end-of-period basis, and the cost of funds had fallen 180 basis points to 6.00%.
- Product design that removes friction - the bank was the first universal bank to credit savings interest monthly and to offer zero fees on 28 essential services including ATM withdrawals, IMPS, RTGS, cash deposits and demand drafts. It reduced the savings-account rate to just 3% for balances up to Rs. 1 lakh, yet CASA deposits still grew 32% year-on-year as of March 2024.
- Branch build-out is the distribution moat - the network has grown 5.6x from 206 branches at merger to 1,147, plus 1,052 ATMs and recyclers opened since merger, alongside digital channels and a WhatsApp banking service.
- Brand trust is treated as a balance-sheet asset - within days of a fraud incident the bank placed a front-page advertisement to reassure customers, a signal of how seriously it treats depositor confidence. Certificate of Deposits, a form of short-term wholesale funding, shrank from Rs. 28,754 crore to Rs. 6,823 crore over five years as retail deposits replaced them.
3. Credit cards: a payments-and-lending platform that deepens the relationship
Over 4.5 million lifetime-free cards issued with industry-first features - dynamic low interest rates, never-expiring rewards and zero interest on cash withdrawals - built without using direct selling agents for the first 700,000 cards.
- Designed to be customer-friendly, not fee-heavy - the card carries no joining or annual fee, no minimum-spend condition, a dynamic APR starting at 9% p.a., interest-free cash withdrawals for up to 48 days, and reward points that never expire.
- Acquired organically, not through agents - the first seven lakh cards were issued entirely through the bank’s own digital channels and marketing, breaking the industry norm of relying on direct selling agents for two or three decades. Spend per active card was 35% higher than the industry average as of March 2022.
- Credit cards achieved operational breakeven in FY25 - the book crossed 4.5 million cards by March 2026, growing 22% year-on-year, with gross spends rising 58% during FY24.
4. Wholesale banking: the derisked corporate book
A deliberately shrunk corporate portfolio - infrastructure exposure reduced from roughly Rs. 20,700 crore to nearly nil - now focused on working-capital lending to investment-grade mid-sized companies, with no meaningful credit loss in seven years.
- Exited project finance and infrastructure - the bank unwound around Rs. 20,700 crores of project financing infrastructure book and reduced it to nearly nil, so that the funded book built since merger of about Rs. 55,000 crore has recorded virtually no credit losses.
- Concentration risk has been dismantled - exposure to the top 20 single borrowers fell from 16% to 5%, and exposure to the top five industries dropped from 41% to 20%, both measured from March 2019 to March 2026.
- Fee income from trade and cash management - the wholesale bank offers letters of credit, bank guarantees, digital cash management with over 3,000 clients, and client FX and derivatives; trade and client FX contributed 10% of total fee income in FY26.
Digital banking and technology
A mobile app rated #1 in India and #4 globally by Forrester, sitting on a modern API and microservices stack that powers underwriting, service and cross-sell - 95% of the bank’s overall transactions are digital.
- The app is the branch for millions - with 29.8 million-plus registrations, the IDFC First App opens in under one second and offers 250-plus features including pre-approved loans and credit cards, a consolidated investment dashboard, in-app video calling and one-click overdrafts against fixed deposits.
- Underwriting uses India’s digital public infrastructure - the bank layers behavioural scorecards, machine-learning models, live facial recognition, digitised bank statements and GST records, and electronic NACH mandates on top of Account Aggregator data to make lending decisions.
- Operations are automated end-to-end - robotic process automation, cognitive OCR and AI/ML tools handle back-office work, while a Partner Assistance WhatsApp implementation serves more than 1,500 partners in real time.
Group structure and partners
A professionally managed bank with no promoter, one wholly owned rural subsidiary, and fresh capital from Warburg Pincus and Platinum Invictus via compulsory convertible preference shares.
- The bank became promoter-less on 1 October 2024 when IDFC Limited and IDFC Financial Holding Company were amalgamated into the bank; accumulated losses were set off against the securities premium account, clearing the path for future dividends.
- IDFC First Bharat Limited, the wholly owned corporate business correspondent, runs 637 rural branches and sourced Rs. 10,984 crore of loans in FY25.
- In August 2025, Warburg Pincus affiliate Currant Sea Investments was allotted CCPS worth Rs. 4,876 crore at Rs. 60 per share, and Platinum Invictus was allotted CCPS worth Rs. 2,623 crore on the same terms, together bringing in roughly Rs. 7,500 crore of growth capital.
- The bank’s long-term credit rating is AA+ (stable) from four agencies, with an AAA rating from CRISIL for its fixed-deposit programme.
