Breaking: IDFC First Bank Shares Plunge 15% in February 2026 Following ₹590 Cr Fraud Disclosure – FinScann Analysis

IDFC First Bank (NSE: IDFCFIRSTB, BSE: 539437) shares witnessed a significant downturn in late February 2026, plunging by 15% in a single trading session. This sharp decline sent ripples across the Indian banking sector and put the spotlight squarely on the private lender, coming hot on the heels of a critical disclosure concerning a ₹590 crore fraud at its Chandigarh branch. The market reaction underscores heightened investor sensitivity to governance issues, even as the broader Nifty Bank index has shown a mixed trend amidst profit booking and resilient banking sector fundamentals in India.

The Catalyst

The primary driver behind the recent dramatic fall in IDFC First Bank's share price is the disclosure of a ₹590 crore fraud involving certain Haryana government entities' accounts at its Chandigarh branch. This significant event came to light on February 23, 2026, when discrepancies were observed between the balances recorded by the bank and those reported by the government entities. The bank confirmed that the fraudulent activities were limited to a specific group of government-linked accounts and did not affect other customers.

In response to the fraud, IDFC First Bank has taken swift action, suspending four suspected employees and initiating strict disciplinary, civil, and criminal proceedings against those responsible. Furthermore, the bank has filed a complaint with police authorities and is in the process of appointing an independent external agency to conduct a forensic audit to determine the full extent of the fraud and identify any gaps in internal controls.

This incident echoes previous concerns regarding operational vigilance, as FinScann previously covered a separate fraud disclosure involving the bank.

While the current fraud is distinct, it highlights the ongoing importance of robust risk management and internal controls within the rapidly expanding private banking space in India.

Financial Forensics

Despite the recent share price correction, IDFC First Bank had shown a robust performance in its Q3 FY26 results. The bank reported a notable 48% year-on-year (YoY) increase in net profit, with net interest income (NII) also jumping to ₹5,492 crore from ₹4,902 crore in the corresponding quarter of the previous financial year. Its Net Interest Margin (NIM) stood at 5.76% in Q3 FY26, which, while slightly down YoY, improved by 17 basis points quarter-on-quarter (QoQ), exceeding expectations.

As of February 20, 2026, prior to this major plunge, the bank's share price was around ₹83.56, with a market capitalization of approximately ₹71,855 crore. Its Price-to-Earnings (P/E) ratio was around 45.63 and Price-to-Book (P/B) ratio stood at 1.53. The 52-week high for the stock was ₹87.00, and the 52-week low was ₹52.50.

However, the ₹590 crore fraud raises immediate questions about the quality of earnings and the bank's internal controls, potentially impacting its asset quality perception despite declining Gross Non-Performing Assets (NPA) and Net NPA ratios in recent years. While the Indian banking system overall is entering 2026 on a strong footing with improved asset quality and capital buffers, isolated incidents like this fraud can dent investor confidence in specific lenders.

Market Impact

The 15% plunge in IDFC First Bank shares is expected to exert downward pressure on the stock in the immediate term, as investors digest the implications of the ₹590 crore fraud. This event comes at a time when the broader Nifty Bank index has shown resilience, with some analysts forecasting a mildly bullish to range-bound outlook for the end of February 2026, holding above crucial support levels like 60,500. The Nifty PSU Bank Index, in contrast, has been on a strong rally, hitting 9,665.80 and marking six consecutive months of growth due to robust Q3 FY26 profits and improved asset quality.

However, such a significant fraud in a private sector bank could trigger cautious sentiment towards the broader banking sector, especially private players, due to concerns about governance and operational risks. Foreign Institutional Investors (FIIs) have shown mixed flows in recent times, and events like this could influence their participation in the banking segment. Domestic Institutional Investors (DIIs) have been providing strong support to the Indian markets, but even their confidence could be tested.

Key Takeaways

• Immediate Term Volatility: Expect continued price volatility for IDFC First Bank shares as the market processes the fraud disclosure and its potential financial repercussions.
• Governance Concerns: The ₹590 crore fraud highlights the critical need for enhanced internal controls and corporate governance, which will be a key monitoring point for investors.
• Forensic Audit is Crucial: The outcome of the independent forensic audit will be vital in determining the true extent of the fraud and the accountability framework within the bank.
• Asset Quality Scrutiny: Despite generally improving asset quality in the Indian banking system, this incident could lead to increased scrutiny of IDFC First Bank's loan book and operational integrity.
• Long-Term Fundamentals: Investors should evaluate if this event represents a systemic issue or an isolated incident, assessing its impact on the bank's long-term growth trajectory and core business strength.
