India’s largest private sector bank does not make headlines for the wrong reasons very often. When it does, the rest of the banking system pays attention. March 2026 is one of those moments.
In the span of seventy-two hours, three things happened in quick succession at HDFC Bank. Its non-executive chairman resigned citing “values and ethics,” the bank’s market cap shed roughly $7 billion, and three senior executives were fired following an internal probe into alleged mis-selling of high-risk bonds to NRI clients through its Dubai branch. Whether these events are connected, parallel, or entirely coincidental is something the public record has not yet settled. But taken together, they have opened a governance conversation that India’s most-watched private lender would rather not be having.
The Resignation Letter That Said Everything and Nothing
On the night of March 18, 2026, HDFC Bank filed a late exchange notification: Atanu Chakraborty, the bank’s part-time non-executive chairman, had resigned with immediate effect.
Chakraborty is not a name that typically moves markets. But his background makes his resignation unusually significant. He is a 1985-batch IAS officer from the Gujarat cadre who retired as Secretary of the Department of Economic Affairs in April 2020, one of the most powerful bureaucratic roles in the country. He joined HDFC Bank’s board in May 2021 and was reappointed by the RBI in May 2024 for a fresh term running until May 2027. He resigned with fourteen months left on that term.
His resignation letter, dated March 17, 2026, was a carefully constructed document. It acknowledged the board, appreciated the secretarial and compliance functions, praised the energy of middle and junior-level employees, and described the HDFC-HDFC Ltd merger as a “momentous event,” while also noting that “the benefits of the merger are yet to fully fructify.” And then came the sentence that wiped $7 billion off the bank’s market value:
“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.”
That was it. No elaboration. No named practice. No named individual. No specific allegation. Just a single sentence from a former senior government official who clearly knew exactly what he was writing, and chose to write precisely that.
The Board’s Response: Bewilderment or Damage Control?
The bank moved fast. Within hours, the RBI had approved the appointment of Keki Mistry, former Vice Chairman and CEO of HDFC Ltd, as interim part-time chairman for three months.
On March 19, the bank held an investor call. What followed was one of the more remarkable exchanges in recent Indian corporate history.
CEO Sashidhar Jagdishan said the board had asked Chakraborty to reconsider the resignation and to soften the language in the letter. Both requests failed. Independent director M.D. Ranganath said Chakraborty was repeatedly asked to point out specific concerns but provided nothing. Director Renu Sud Karnad said the development was “a bit baffling” because the board had “repeatedly asked him” what had triggered the decision and whether anything needed to be set right, and he had not pointed to anything specific.
Keki Mistry, the new interim chairman, put it plainly:
“What caused that letter to be sent yesterday is something which, really to my mind, defies logic.”
Harsh Bhanwala, chairperson of the governance and nomination committee, said all committee discussions had concluded in unanimous resolutions with no difference of opinion from Chakraborty on record.
The board’s collective position was: we don’t know what he meant, and he wouldn’t tell us.
Investors were unconvinced.
The Investor Call: When BlackRock Gets Frustrated on a Live Call
Less than thirty minutes into the call, Prashant Periwal of BlackRock, which holds more than 3% of HDFC Bank, made his frustration public.
“So far, whatever I heard on this call doesn’t make me any wiser than I was an hour ago. Look, if it is too early and you guys have no idea why it was happening, how can you say there’s nothing behind it?”
He pressed further:
“What exactly was it? Because he was the chairman of the bank. He was not like any other employee that resigns saying something and it means nothing.”
Prashant Poddar, a portfolio manager from Abu Dhabi Investment Authority, described the resignation letter as “reputation maligning” and pushed back hard on the bank’s framing:
“If someone has to insinuate towards something, there should be an explanation in the letter, or else this is scathing. Rather than sending regards, the bank should ask RBI to investigate.”
Principal Asset Management’s equity research analyst Siva Natarajan said the language used was “very, very strong” and that he was struggling to accept that there was “nothing specific” behind it.
Foreign institutional investors collectively hold over 47% stake in HDFC Bank. That kind of shareholding means this was not a boardroom inconvenience. It was a conversation happening in front of the bank’s most consequential owners.
The AT-1 Bond Scandal: The Background Nobody Wanted to Talk About
On March 21, 2026, two days after the chairman’s resignation, HDFC Bank terminated three senior executives following an internal investigation into alleged mis-selling of Credit Suisse Additional Tier-1 (AT-1) bonds to NRI clients through its Dubai International Financial Centre (DIFC) branch.
The three executives fired were Sampath Kumar (Group Head of Branch Banking), Harsh Gupta (Executive Vice President for Middle East, Africa and NRI Onshore Business), and Payal Mandhyan (Senior Vice President). Gupta and Mandhyan had already been suspended in January 2025 when the internal probe was first initiated. Kumar, according to reports, may not have been directly involved in the mis-selling but was held accountable because the lapses occurred under his supervision.
To understand why this matters, you need to understand what AT-1 bonds are.
What Are AT-1 Bonds?
Additional Tier-1 bonds were introduced after the 2008 global financial crisis as a mechanism to ensure that investors, not taxpayers, absorb losses during a bank failure. They sit at the absolute bottom of the capital structure. They offer higher yields in exchange for taking on equity-like risk. In extreme scenarios, they can be written to zero, entirely wiped out, without any formal default event.
This is exactly what happened during the Credit Suisse crisis in March 2023. When UBS acquired Credit Suisse in a government-facilitated rescue, approximately $20 billion worth of Credit Suisse AT-1 bonds were written off completely. Equity holders actually received something. AT-1 bond holders received nothing.
This was unprecedented and sent shockwaves through global fixed income markets.
In India, retail investors are barred from buying AT-1 bonds. Sales are permitted only to “professional investors,” broadly defined as individuals with more than $1 million in investable assets who are presumed to understand the risks involved.
What Allegedly Happened at HDFC Bank’s Dubai Branch
According to reporting by Bloomberg and the Khaleej Times, investors, many of them NRIs, alleged that HDFC Bank executives sold them Credit Suisse AT-1 bonds without adequately explaining the instruments’ risk profile. Several investors claimed they were misled into moving Foreign Currency Non-Resident (FCNR) deposits from India to Bahrain in order to invest in these bonds.
The more serious allegation is one of regulatory arbitrage. Some investors told the Khaleej Times that they were sold AT-1 bonds even though they did not meet DIFC eligibility thresholds. Certain clients alleged their KYC profiles were altered to upgrade them to “professional client” status, the classification required to access high-risk structured products under UAE regulations. One Dubai resident, Varun Mahajan, told the Khaleej Times he lost $300,000 on Credit Suisse AT-1 bonds through this channel.
The timeline traces the full arc of how this unravelled:
| Period |
Event |
| March 2023 |
Credit Suisse AT-1 bonds written to zero during UBS rescue |
| Early 2025 |
HDFC Bank initiates internal probe; two executives placed on leave |
| July 2025 |
Formal complaint filed with Nagpur’s Economic Offences Wing |
| September 2025 |

| October 2025 |
Executives placed on “gardening leave” while investigation continues |
| March 18, 2026 |
Internal investigation concludes; chairman resigns same day |
| March 21, 2026 |
Three senior executives terminated |
HDFC Bank’s response to Bloomberg in October 2025 had been: “With reference to the sale of Credit Suisse AT1 Bonds, the bank has not come across any instances of mis-selling till now.” By March 2026, after completing its internal review, the bank acknowledged it had found gaps in client onboarding and compliance procedures at its DIFC branch and had taken remedial steps.
The Compliance Trail: This Was Not Isolated
The AT-1 bond issue and the chairman’s resignation are the most dramatic events, but they exist inside a broader pattern of regulatory friction that has been building for some time. Reuters compiled the full compliance timeline:
| Period |
Event |
| September 2024 |
Fined ₹10 million by RBI for violations of deposit rate rules and below-standard debt collection practices |
| June 2025 |
CEO Sashidhar Jagdishan named in a fraud complaint linked to a loan recovery case; bank called the allegations “malicious and baseless” |
| September 2025 |
Dubai’s DFSA restricts DIFC branch from onboarding new clients |
| November 2025 |
Fined ₹9.1 million by RBI for compliance failures including use of multiple benchmarks in the same loan category and KYC outsourcing issues |
| March 2026 |
Chairman resigns citing values and ethics; three executives fired |
None of these events individually constitute a crisis. But the accumulation is what governance analysts flag as concerning. InGovern’s Shriram Subramanian put it plainly:
“HDFC Bank will lose its governance premium or people will start questioning it if the bank doesn’t proactively do something about this matter.”
The Merger Shadow
One detail in Chakraborty’s resignation letter has been widely noted. He said the practices he observed had occurred “over the last two years.” The merger of HDFC Ltd with HDFC Bank became effective on July 1, 2023, approximately two and a half years before his resignation.
This is not proof of a causal link. But it is a temporal overlap that is hard to ignore.
The HDFC-HDFC Bank merger was one of the largest in Indian corporate history, a $40 billion transaction that created a combined balance sheet of over ₹18 lakh crore and made the entity the second-largest bank in the country. HDFC Bank now operates 9,616 branches across 4,170 cities, serves over 120 million customers, and carries a balance sheet of approximately ₹41 trillion as of December 2025.
Large mergers are not just financial transactions. They are culture integration events. Two institutions with different leadership styles, decision-making hierarchies, escalation norms, and ways of resolving internal disagreement are suddenly expected to function as one coherent organisation. That process is rarely seamless, and in the immediate post-merger period, governance continuity is acutely vulnerable.
Chakraborty himself acknowledged in the letter that the benefits of the merger were “yet to fully fructify.” Whether that was a comment on business performance, cultural integration, or governance clarity is something only he knows.
The RBI’s Position
In an unusually direct statement for a banking regulator, the Reserve Bank of India said on March 19:
“HDFC Bank is a Domestic Systemically Important Bank (D-SIB) with sound financials, professionally run board, and competent management team. Based on our periodical assessment, there are no material concerns on record as regards its conduct or governance.”
The regulator approved Keki Mistry’s appointment as interim chairman and said it would continue engaging with the bank’s board and management on the way forward.
The language is measured and deliberate. “No material concerns on record” is not the same as “everything is fine.” It is the language of a regulator who has reviewed periodic disclosures and formal compliance records, and is communicating on the basis of what is officially documented, not on the basis of whatever Chakraborty observed but chose not to write down.
Macquarie removed HDFC Bank from its marquee buy list, though it maintained an “outperform” rating. The distinction matters. Analysts are separating the business fundamentals from the governance uncertainty. The bank’s operations are not in question. The governance signal is.
What We Still Don’t Know
This is the honest part of the story.
We do not know specifically what Chakraborty observed. His letter was carefully worded by someone who spent decades in government and understands the weight of every sentence in a formal document. The phrasing “happenings and practices,” used in the plural, suggests more than a single incident. His mention of middle and junior management as the “core of a reimagined organisation” implies some level of concern about the tone or conduct at the senior level.
We do not know whether the AT-1 bond issue and the chairman’s resignation are directly connected. The timing is notable: the internal probe concluded on March 18, the same day the resignation was received. But the bank has not confirmed or denied any such link.
We do not know whether the KYC manipulation allegations at the Dubai branch represent isolated actions by rogue employees or reflect a broader sales culture problem.
We do not know whether Chakraborty will say anything further. He may not. His letter was precise enough to signal concern but vague enough to prevent legal exposure. That calibration, from a man of his experience, appears intentional.
Why This Matters Beyond HDFC Bank
HDFC Bank is not just another bank. It is a Domestic Systemically Important Bank, meaning its stability is treated as structurally significant to the Indian financial system. With over 47% foreign institutional ownership, it is one of the most globally held Indian financial stocks. When BlackRock and ADIA ask hard questions on an investor call, the conversation is not just about one institution.
The governance question being raised here is harder than “did the bank break a rule.” The RBI can fine a bank for breaking a rule. What cannot be easily regulated is the culture gap between what an institution says about its values and what actually happens in a branch in Dubai, in a sales conversation with an NRI depositor, in a board meeting where the chairman feels he cannot stay.
India’s private banking sector has built its reputation on the contrast with public sector banking: faster, cleaner, more professionally governed. That reputation is not unlimited. It has to be maintained. And when the chairman of India’s largest private bank resigns citing ethics, the entire system has to examine whether the governance standards that built that reputation are still being upheld.
