Fraud Bombshell: On February 21, 2026, IDFC First Bank disclosed a fraud at its Chandigarh branch involving ₹590 crore in Haryana government-linked accounts. Employee collusion, forged cheques, control overrides. The bank has already repaid ₹583 crore to affected departments and initiated a KPMG forensic audit. The stock dropped -11.6% in three months, and it shows. ROA is still under 0.5%. But the Dec quarter results (released Feb 23) showed margins finally inflecting. The question: is this temporary good news buried under permanent bad optics?
02 — Introduction
Seven Years In. Still Learning What a Profit Margin Is.
Let’s start with the timeline. December 18, 2018: IDFC Bank merged with Capital First. The resulting entity was called IDFC First Bank. Since then, this bank has been a financial laboratory for how not to run a balance sheet — and accidentally, how to eventually turn it around.
For six years, the bank lost money on its liability side while making money on its asset side. Why? Because it inherited ₹57,600 crore in wholesale borrowings and ₹22,000 crore in certificates of deposit that were expiring and had to be constantly rolled over. The cost? Brutal. The bank paid 7.8% just to fund itself in 2019. By December 2025, that cost had dropped to 6.11%. That’s a structural achievement that took seven years to hammer out.
And NOW — finally, finally — the bank is starting to look like a normal bank. Q3 FY26 saw NIM expand, cost of funds decline 12 bps QoQ, and PAT jump 48% YoY. For a millisecond, the equity story looked real.
Then February 21, 2026 happened. ₹590 crore fraud at one branch. Haryana government deposits hit. KPMG audit initiated. Stock down from ₹87 to ₹70. The market learned that sometimes your best progress is hiding a very large problem. This is the story of IDFC First Bank: a bank that’s not broken, but definitely bent.
Concall Tone (Feb 23): Management called the fraud “the oldest kind of fraud probably known to banking” and “confined to one branch.” The CEO also said, absent this issue, Q4 would’ve been “very solid.” Translation: things were improving until they literally weren’t.
03 — Business Model: WTF Do They Even Do?
It’s a Bank. With a Complicated History. And Big Ambitions.
IDFC First Bank operates across three main verticals: corporate banking, consumer banking, and rural banking. It’s not a boutique lender; it’s a universal bank trying to build scale and profitability simultaneously—a task that requires more capital, smarter underwriting, and better luck than most banks get.
Loan book breakdown (FY25): Retail mortgage-backed loans (29%), wholesale (18%), vehicle loans (11%), MSME (9%), rural finance (8%), and everything else (25%). The bank has been actively de-risking its microfinance portfolio from 6.6% in FY24 down to 4% in FY25—recognizing that MFI is where real problems hide.
Deposit strategy: This is where the real battle is. The bank has ₹2.83 trillion in customer deposits (+24% YoY), with CASA at ₹1.5 trillion (+33% YoY). That’s 51.6% CASA ratio—almost at peer levels. The problem: it cost money to build this franchise. Savings accounts are priced at 3–7% depending on size. That’s expensive money. To compete with HDFC Bank and ICICI Bank, you don’t price like them; you price better. That’s margin erosion by design.
The real moat? Digital capabilities. The app is rated 4.9/5 on Google Play, 4.8 on App Store. 27 million downloads. 19.9 million users. 1.3 million monthly transacting users. For a 7-year-old bank, that’s best-in-class. The bank issues 17.8 million FASTag live tags at 37% market share. It’s a technology company disguised as a bank—which is both strength and weakness.

The NIM Story (Very Important): NIM on AUM basis was 5.76% in Q3, up 17 bps QoQ. Management guided Q4 NIM to ~5.85%. Drivers: cost of funds -12 bps QoQ, CRR impact +2–3 bps, capital raise benefit. This is the margin inflection everyone’s been waiting for. The problem: it’s now overshadowed by the fraud disclosure.
P/E Recalculation: Annualised EPS Q3×4 = ₹0.62 × 4 = ₹2.48. CMP ₹70 ÷ ₹2.48 = P/E 28.2x (annualised). Full-year FY25 EPS was ₹2.04, so stock on trailing FY25 is P/E 34.3x. On forward estimates (if the bank executes), the premium compresses—but “if” is doing a lot of work here.
