HDFC Bank Under Scrutiny: Stock Plunges Amid SEBI Probe

Introduction: A Chairman's Exit Shakes Investor Confidence

HDFC Bank, India's largest private lender, is navigating a period of intense scrutiny following the abrupt resignation of its part-time chairman, Atanu Chakraborty, on March 18, 2026. Chakraborty's departure, accompanied by a letter citing "certain happenings and practices within the bank" that were incongruent with his personal ethics, triggered a significant sell-off in the bank's shares and prompted a regulatory review. The event has cast a spotlight on the bank's corporate governance, challenging its long-held reputation for stability and raising questions among investors and analysts.

The Immediate Market Fallout

The market's reaction to the chairman's resignation was swift and severe. HDFC Bank's stock plummeted 8.7% in the trading session immediately following the disclosure of the letter. The selling pressure continued over the next few days, wiping out approximately Rs 1.6 lakh crore ($16.3 billion) in market capitalization over just three sessions. On one particular Friday, the stock touched an intraday low of Rs 759.25, a decline of nearly 3 percent, as reports of a regulatory probe gained traction. The sharp fall pushed the stock near its 52-week low, marking its worst monthly performance since the market crash of March 2020.

SEBI Initiates a Preliminary Review

Adding to the bank's challenges, the Securities and Exchange Board of India (SEBI) has initiated a preliminary review into the matter. According to reports, the regulator's department overseeing corporate disclosures and governance is examining the contents of Chakraborty's resignation letter. The probe aims to verify the claims made and determine whether there were any lapses in the fiduciary duties of the former chairman or other board members. A key focus is to ascertain if other directors were aware of material information that was not properly documented or disclosed, which would constitute a serious governance breach.

HDFC Bank's Internal Response and Leadership Changes

In response to the escalating concerns, HDFC Bank announced that it has appointed external domestic and international law firms to conduct an independent assessment of the issues raised in Chakraborty's letter. The bank stated this move is intended to ensure an objective evaluation and uphold its governance standards. In the interim, to ensure leadership continuity, the bank appointed Keki Mistry as the interim part-time chairman for a period of three months, a decision approved by the Reserve Bank of India (RBI). Mistry has publicly stated that there are no major issues and has downplayed speculation about an internal power struggle.

Reports of Internal Friction Surface

While the bank's management has sought to reassure investors, media reports have suggested deeper issues. The Financial Times reported that the resignation was triggered by a power struggle between Chairman Atanu Chakraborty and CEO Sashidhar Jagdishan. The tensions, reportedly simmering for months, were centered on strategic disagreements, governance practices, and the CEO's impending reappointment. According to the report, the friction peaked over the proposed renewal of Jagdishan's tenure, indicating a clash over leadership style and control beyond simple compliance matters.

Key Developments and Market Impact

The sequence of events has created significant uncertainty for investors. The combination of a high-profile resignation citing ethical concerns and a subsequent regulatory probe has put the bank's valuation under pressure.

Broader Governance Issues and Executive Departures

The chairman's exit coincided with other governance-related developments at the bank. HDFC Bank confirmed the termination of three senior executives, including the group head of retail branch banking, Sampath Kumar. The dismissals followed an internal investigation into the alleged mis-selling of Credit Suisse's Additional Tier-1 (AT-1) bonds to NRI clients through the bank's UAE operations. This separate issue has added to the narrative of internal control challenges, further unsettling investors.

Analyst and Brokerage Perspectives

The investment community's reaction has been mixed. Highlighting the uncertainty, Jefferies' top equity strategist Christopher Wood removed HDFC Bank from both his Asia ex-Japan and global long-only equity portfolios. Similarly, Goldman Sachs downgraded its stance on the Indian market to 'marketweight', citing broader economic risks. However, many analysts maintain a long-term positive outlook on the bank's fundamentals. The consensus rating remains a 'Strong Buy' with an average 12-month price target of ₹1,139.13. Brokerages like BofA Securities and Nomura have maintained 'Buy' ratings, though Nomura trimmed its target price. Analysts at Axis Securities noted that while the bank's operational performance remains strong, the governance concerns could delay a recovery in its valuation.

Conclusion: A Path to Restoring Confidence

HDFC Bank is at a critical juncture, facing a significant test of its corporate governance framework. While the RBI has stated it found "no material concerns on record," the ongoing SEBI review and the bank's own internal investigation will be pivotal in shaping the narrative moving forward. The market is closely watching for clarity on leadership succession and the findings of these probes. Restoring investor confidence will depend on transparent communication and decisive actions to address any identified shortcomings, which will be essential for the bank to reclaim its premium valuation and solidify its standing in the financial sector.
