HDFC Bank Shares Drop Sharply After Chairman Atanu Chakraborty Quits Citing Ethical Concerns
HDFC Bank shares fell sharply after Chairman Atanu Chakraborty resigned abruptly. The RBI confirmed no governance concerns, and Keki Mistry was appointed interim chairman, reassuring investors amid sudden leadership changes.
The part‑time chairman of HDFC Bank, Atanu Chakraborty, resigned from his post on Wednesday in a surprise development that sent the bank’s shares tumbling on Indian markets. His departure has sparked questions among investors, even as regulators and the bank’s board moved quickly to reassure stakeholders.
Chakraborty stepped down with immediate effect, citing differences between his personal values and certain internal practices at the bank. He did not allege any specific misconduct, but the vague wording of his resignation letter raised eyebrows on Wall Street and Dalal Street.

What Happened in the Markets
HDFC Bank’s share price dropped sharply on Thursday, in some sessions falling around 9% from the previous close, wiping out almost INR 1 lakh crore in market value in minutes. This was the steepest single‑day fall for the bank’s stock in several years.
The broader stock market indices also reacted, with major benchmarks like the SENSEX and NIFTY50 trading weaker and HDFC Bank among the top laggards.
What the HDFC Chairman’s Letter Said
In his resignation note, Chakraborty wrote that “certain happenings and practices… are not in congruence with my personal values and ethics.” He added that there were “no other material reasons” for his decision. The letter did not detail what those practices were, which fuelled speculation among analysts.
Chakraborty had been reappointed in 2024 for a term running through 2027, making the sudden exit unexpected.
RBI and Bank Reassure Investors
The Reserve Bank of India (RBI), the country’s central banking regulator, issued a statement saying it sees no material concerns regarding HDFC Bank’s governance, conduct, or financial health following the chairman’s exit. The regulator stressed that the bank remains well‑capitalised, financially sound, and properly managed.
The RBI also approved the appointment of Keki Mistry, a veteran former executive with deep experience in the HDFC Group, as the interim chairman for a three‑month period. Mistry has publicly denied any board‑level power struggle or governance gap and said the bank’s operations are “aligned” with good corporate standards.
Who is Keki Mistry?
Keki M. Mistry is the interim non-executive chairman of HDFC Bank following Atanu Chakraborty’s resignation in March 2026. He was previously the Vice-Chairman and CEO of HDFC Ltd before its merger with HDFC Bank in July 2023. A qualified Chartered Accountant with over four decades of experience in banking and financial services, Mistry also serves on the boards of HDFC Life, HDFC ERGO, Tata Consultancy Services, Flipkart Singapore, and other major companies, and holds key advisory roles with SEBI, B20 South Africa 2025, and IFSCA.
Reactions from Markets and Experts
While the RBI and bank leadership offered calm reassurances, some market analysts remain cautious. Certain brokerages have revised outlooks on the stock, citing lingering governance uncertainty as a factor in investor sentiment.
Corporate governance experts have suggested the bank should provide clearer answers on the concerns mentioned by Chakraborty to rebuild confidence fully.
