HDFC Bank Stock Falls 9% After Chairman Resigns, SEBI Investigates

Introduction

HDFC Bank, India's largest private lender, faced significant market turmoil as its shares plunged following the abrupt resignation of its part-time chairman, Atanu Chakraborty. The exit, which cited ethical concerns, triggered a sharp sell-off, erased over ₹1 lakh crore in market capitalization, and prompted a preliminary review by the Securities and Exchange Board of India (SEBI).

The Chairman's Abrupt Departure

The crisis began on March 18 when Atanu Chakraborty, who had joined the bank's board in 2021, resigned with immediate effect. In his resignation letter, he stated that "certain happenings and practices within the bank" over the past two years were "not in congruence with my personal values and ethics." This unexpected move from the former senior bureaucrat caught the board and investors by surprise. The bank's management, including CEO Sashidhar Jagdishan, reportedly urged Chakraborty to reconsider or provide more clarity, but he declined.

Severe Market Reaction

The news sent shockwaves through the market. On the National Stock Exchange (NSE), the stock fell as much as 9%, touching intraday lows of ₹770 and ₹759.25 in subsequent sessions. The bank's American Depositary Receipts (ADRs) listed in the US also plunged by over 8%. This was the stock's steepest single-day fall since the COVID-19 market crash in March 2020.

Massive Wealth Erosion

The sharp decline in stock price led to a substantial erosion of investor wealth. In the immediate aftermath, the bank's market capitalization was reduced by nearly ₹1 lakh crore. Over two trading sessions, the total market cap erosion reached approximately ₹95,575.65 crore, making HDFC Bank one of the biggest losers among India's most valued companies during that period. An earlier surfacing of the letter had also caused an 8.7% drop, wiping out ₹1.35 lakh crore in market value over three sessions.

Key Financial Impact Summary

Regulatory Scrutiny and Brokerage Exit

Adding to the pressure, market regulator SEBI initiated a preliminary review of Chakraborty's resignation letter to understand the underlying governance issues. The situation was further compounded when global brokerage Jefferies announced its exit from its stake in HDFC Bank. Jefferies also trimmed its overall weightage for India, signaling broader caution among foreign institutional investors (FIIs), who hold about 48% of the bank's shares.

Bank's Damage Control Measures

HDFC Bank's board moved swiftly to manage the fallout. With approval from the Reserve Bank of India (RBI), it appointed Keki Mistry, a veteran of the HDFC group and former CEO of HDFC Ltd., as the interim part-time chairman for a three-month period. The bank's management also held an emergency conference call with analysts and investors to address concerns. During the call, Mistry assured stakeholders that there was "no power struggle within the bank" and that the board was unaware of the specific issues raised by Chakraborty.

Regulatory and Analyst Perspectives

In a rare move, the RBI issued a statement defending the lender, describing HDFC Bank as a "systemically important bank" with "sound financials, a professionally run board and a competent management team." The regulator stated that there were no material concerns on record regarding the bank's conduct or governance. Brokerages like Motilal Oswal noted that while the event dampened near-term sentiment, the swift leadership transition provided some comfort. However, analysts emphasized that clarity on a new permanent chairman and the performance in coming quarters would be crucial for restoring investor confidence.

Conclusion

The sudden resignation of Atanu Chakraborty has placed HDFC Bank under intense scrutiny from investors and regulators alike. While the bank's leadership and the RBI have moved to contain the damage, the episode has highlighted underlying governance concerns. The path forward will depend on the bank's ability to ensure operational stability, provide clarity on the issues raised, and appoint a new chairman to guide it through this challenging period.
