Mumbai – HDFC Bank, India’s largest private sector lender, saw a major shake-up at the top on March 18 when its part-time chairman and independent director, Atanu Chakraborty, stepped down with immediate effect. He said certain practices he saw in the bank over the past two years did not match his personal values and ethics. The bank quickly named Keki Mistry, a long-time group veteran, as the interim part-time chairman. The Reserve Bank of India gave its approval for this change.
This news came as a surprise to many and hit the stock market hard. HDFC Bank shares fell as much as 9 per cent in early trading on March 19. They touched a 52-week low near Rs 770 before recovering some ground. The drop wiped out more than Rs 1 lakh crore in market value. The bank’s American depositary receipts in the US also fell over 7 per cent. Investors worried about what this sudden exit meant for the bank’s leadership and future.

Atanu Chakraborty, a retired IAS officer from the 1985 Gujarat batch, had joined the HDFC Bank board in May 2021. He became part-time chairman soon after. His term was extended in May 2024 and was set to run until May 4, 2027. During his time, he oversaw the big merger with HDFC Ltd in 2023. This deal turned HDFC Bank into one of the country’s strongest financial groups. But in his letter, he noted that the full benefits of this merger were still not seen.
The Resignation Letter and What It Said
Chakraborty wrote a clear letter to Dr H K Bhanwala, chairman of the bank’s Governance, Nomination and Remuneration Committee. He said: “Certain happenings and practices within the bank, that I have observed over last two years, are not in congruence with my personal values and ethics. This is the basis of my aforementioned decision.” He added that there were no other material reasons for his exit.
He also thanked the board, independent directors and senior management for their support. He praised the energy of the middle and junior staff. He said they could help build a strong future for the bank. He specially noted the good work of the secretarial, compliance, audit and group oversight teams. The full letter was filed with the stock exchanges on March 18 evening.
The bank told the exchanges that Chakraborty had resigned and there were no other reasons beyond what he wrote. This helped calm some fears that bigger problems existed.
Bank Acts Fast: Keki Mistry Takes Charge
Within hours, the bank moved to fill the gap. It appointed Keki Mistry as interim part-time chairman for three months starting March 19. The RBI gave quick approval. This showed the regulator was comfortable with the change and the bank’s overall health.
Keki Mistry is 70 years old and a chartered accountant. He joined HDFC Ltd way back in 1981. He rose to become vice chairman and CEO of HDFC Ltd before the merger. After the merger in July 2023, he stayed on the HDFC Bank board as a non-executive, non-independent director. He brings more than 40 years of experience in housing finance and banking.
In a conference call with analysts and investors on March 19 morning, Mistry spoke clearly. He said the board had asked Chakraborty for more details on his concerns but none were given. “What prompted this communication defies logic,” he noted. He added there was no power struggle on the board and everyone worked as one team. Mistry also said he would not have taken the job at his age if the bank’s systems did not match his own values. He told everyone that the RBI was fully in the loop and comfortable. The bank said its focus on transparency, integrity and long-term growth remained the same.
MD and CEO Sashidhar Jagdishan also spoke. He said the bank was committed to keeping the trust of all stakeholders. He noted that talks with the RBI were good and the regulator was supportive.
How the Market Reacted
The share price reaction was sharp. Before the news, HDFC Bank shares closed at around Rs 843 on March 18. On March 19, they opened much lower and fell up to 9 per cent. At one point, the stock hit Rs 770. This took the market capitalisation down by over Rs 1 lakh crore from its previous level of nearly Rs 13 lakh crore. Later in the day, after the management call, the drop eased to about 5 per cent. The stock was still among the worst performers on the Sensex and Nifty.

This fall came at a time when the broader market was also under pressure from global issues like rising oil prices. But the chairman news was the main trigger. Many investors sold shares because they felt unsure about governance and leadership stability.
Who Is Atanu Chakraborty? A Look at His Background
Atanu Chakraborty spent over 35 years in government service. As a senior IAS officer, he held key posts in finance. He was Secretary in the Department of Economic Affairs in the Union Finance Ministry till 2020. He also worked on disinvestment and infrastructure projects. He served as alternate governor on the World Bank board and chaired the National Investment and Infrastructure Fund. His government experience made him a strong choice for the HDFC Bank board in 2021. Many saw him as a steady hand during the big merger period.
His exit after nearly five years on the board has raised questions about boardroom differences. But both he and the bank have made it clear there was no wrongdoing or regulatory red flag.
Post-Merger Journey of HDFC Bank
The merger of HDFC Ltd with HDFC Bank in 2023 was one of the biggest in Indian banking history. It created a giant with huge reach in home loans, deposits and other services. The combined entity became the second largest bank in the country by some measures and the top private lender by market cap.
Chakraborty joined just before this big change. In his letter, he pointed out that the full gains from the merger were still coming. The bank has faced some real-world tests since then. It worked on mixing two different cultures – one from a housing finance firm and one from a bank. Deposit growth, especially low-cost deposits, has been a focus area. Competition for customer money is high. Net interest margins faced some pressure too. But the bank has strong points like its branch network, digital push and valuable subsidiaries such as HDFC Life and HDFC Securities.

Analysts who follow the bank closely say the fundamentals remain solid. The long-term story of growth in retail lending and wealth management is still intact. The quick appointment of Mistry, who knows the old HDFC culture well, is seen by some as a positive step to keep things steady.
What the Management and Experts Say
During the investor call, Keki Mistry stressed that the board had found no material issues. He said all disclosures were proper and the bank was following every rule. “The institution is anchored in transparency and integrity,” he said. The board will meet soon to plan the next steps for a permanent chairman.
Proxy advisory firm Institutional Investor Advisory Services noted that the RBI’s fast approval was a good sign. It meant less worry for shareholders even if some alarm bells rang. Other market watchers said the stock could stay weak in the short term due to this news but strong buyers might see it as a chance to pick up shares at lower prices.
No one from the bank or regulator has spoken about any specific “happenings” that Chakraborty mentioned. The focus now is on smooth handover and business as usual.
Impact on Investors and Governance
This event puts the spotlight on board independence and ethics in big Indian companies. Independent directors like Chakraborty are meant to watch over management and protect shareholder interests. When one steps down citing values, it makes people think about how boards work.
For common investors who hold HDFC Bank shares through mutual funds or directly, the drop means paper losses today. But the bank has a long history of steady growth. It serves crores of customers across India. Its subsidiaries add extra strength. Many experts say one leadership change should not change the big picture if the business stays strong.
The RBI’s role here is important. As the banking regulator, it keeps a close eye on systemically important banks like HDFC. The quick nod to Mistry shows the system is working without bigger worries.
Looking Ahead for HDFC Bank
With Mistry at the helm for the next three months, the bank will focus on daily operations and long-term plans. The board will now start the search for a new part-time chairman. Mistry’s deep knowledge of the HDFC group should help keep things calm.
The bank has called its next earnings update soon. Investors will watch for any comments on deposit growth, loan book health and merger progress. For now, the message from the top is clear: no material problems, strong governance and full focus on customers and growth.
HDFC Bank remains a key player in India’s financial world. This episode shows that even big banks can face sudden changes at the top. But with quick action and clear words from the new leadership, the path forward looks steady.
