In a move that sent shockwaves through India’s banking sector and wiped out billions in market value, Atanu Chakraborty, the part-time Chairman and independent director of HDFC Bank, resigned with immediate effect on March 18, 2026. His resignation letter, dated March 17, cited a fundamental misalignment between certain bank practices and his personal values.
In the letter addressed to the Chairman of the Governance, Nomination and Remuneration Committee, Chakraborty wrote: “Certain happenings and practices within the bank, that I have observed over the last two years, are not in congruence with my personal values and ethics. This is the basis of my aforementioned decision. I confirm that there are no other material reasons for my resignation other than those stated above.”
He had joined the bank’s board in May 2021 and played a role during the landmark merger with HDFC Ltd in 2023, which created India’s largest private sector lender. His term had earlier been extended until May 2027.
Market Reaction and Immediate Fallout
The announcement triggered a sharp sell-off in HDFC Bank shares. The stock plunged as much as 9% in early trading on March 19, hitting a near two-year low and erasing over ₹1 lakh crore (approximately $7-12 billion, depending on reports) in market capitalisation in a single session. It eventually closed around 5% lower, marking one of its steepest single-day declines in recent years.
The bank swiftly convened an investor call to reassure stakeholders. Management, including CEO Sashidhar Jagdishan and incoming interim chairman Keki Mistry, insisted there were no material governance, financial, or operational issues. They revealed that the board had urged Chakraborty to reconsider his resignation or at least soften the language in his letter, but he declined.
The Reserve Bank of India (RBI) quickly approved the appointment of Keki Mistry — a veteran HDFC insider and former CEO of HDFC Ltd — as interim part-time chairman for three months. In a rare public statement, the regulator affirmed that HDFC Bank remained a systemically important lender with “sound financials, professionally run board and competent management,” and saw “no material concerns on conduct or governance.”
Subsequent Developments: Employee Terminations in Dubai
Just days after the resignation, HDFC Bank terminated three senior employees linked to compliance lapses at its Dubai International Financial Centre (DIFC) branch. The individuals included Sampath Kumar (Group Head of Branch Banking), Harsh Gupta (EVP for Middle East, Africa and NRI business), and Payal Mandhyan (SVP).
The terminations stemmed from an internal probe into alleged mis-selling of Credit Suisse Additional Tier-1 (AT1) bonds to NRI clients. These high-risk instruments were reportedly pitched as safe or fixed-return products. Issues included inadequate client onboarding, inflated income declarations to qualify clients as “professional,” and failures in risk disclosure. The episode gained fresh scrutiny after the 2023 Credit Suisse crisis, when AT1 bonds were written down to zero, causing significant investor losses.
The Dubai Financial Services Authority (DFSA) had earlier barred the branch from onboarding new clients due to these compliance gaps. The bank stated that it had completed a “detailed and objective review,” taken remedial actions, and made personnel changes. CEO Jagdishan emphasised that the matter was isolated and had been addressed through disciplinary processes.
Criticism and Questions Over Chakraborty’s Approach
The vague nature of Chakraborty’s resignation — highlighting “ethics” without specifics after two years of observation — drew sharp criticism. Opinion pieces, including one by Subhash Chandra Garg in The Quint, questioned whether his public exit without prior documented escalation to the full board, regulators, or shareholders constituted responsible governance.
Critics argued that an independent director has a duty to raise material concerns internally first rather than issue a cryptic statement that triggered panic selling and reputational damage. Chakraborty later described his departure in media interviews as a “routine” parting of ways due to ideological differences, not any specific wrongdoing, further fuelling perceptions of inconsistency.
Some reports suggested underlying tensions possibly related to post-merger cultural integration, aggressive growth strategies, CEO succession (including discussions around a potential third term for the current CEO), or accountability over the Dubai episode. However, the bank and regulators have maintained that no systemic issues exist.
Broader Implications
HDFC Bank continues to enjoy strong fundamentals as India’s largest private sector lender. The episode, however, has spotlighted challenges in post-merger integration, overseas compliance, and the delicate role of independent directors in balancing fiduciary duties with public communication.
While Chakraborty’s stand has been viewed by some as principled dissent, others see it as poor optics that harmed retail shareholders and depositors without delivering clear evidence of widespread misconduct. The swift regulatory endorsement and targeted staff actions suggest the bank is treating the matter as containable rather than existential.
As the board searches for a permanent chairman and any further probes unfold, the episode serves as a reminder of the high stakes around governance transparency in India’s marquee financial institutions. For now, HDFC Bank and its regulators project stability — but the sudden exit has left lingering questions about both the bank’s internal practices and the ethics of how its former chairman chose to exit.
