HDFC Bank shares fell to their lowest level in nearly two and a half years on Thursday as investors reacted to a United States securities lawsuit, regulatory concerns and uncertainty surrounding the tenure of chief executive Sashidhar Jagdishan.
The stock declined as much as 2.37% to ₹710 during the session, extending its losing streak to three trading days. It has now fallen approximately 28% in 2026 and is heading towards its weakest annual performance since 2008.
The decline in HDFC Bank shares also weighed heavily on the broader market because the lender carries the largest weight in the Nifty 50.
The Nifty closed 0.48% lower at 24,090.85, while the BSE Sensex declined 0.7% to 76,933.59. Indian equities underperformed several other Asian markets, which benefited from renewed optimism around artificial-intelligence spending following Nvidia’s quarterly results.
US Investors File Securities Lawsuit
The immediate concern centres on a proposed securities class action filed in the US District Court for the Southern District of New York on August 13.
The complaint names HDFC Bank, Jagdishan and chief financial officer Srinivasan Vaidyanathan as defendants. It seeks to represent investors who acquired the bank’s US-listed securities between July 17, 2023 and May 26, 2026.
The plaintiff alleges that HDFC Bank made materially misleading statements or failed to disclose important information concerning its operations, internal controls and financial reporting.
A central allegation concerns approximately ₹45 crore, or around $4.7 million, allegedly paid to the Maharashtra State Road Development Corporation.
The lawsuit claims the amount was recorded as marketing or sponsorship expenditure while effectively providing the state agency with additional interest to attract large deposits. It alleges that MSRDC received an effective interest rate of 6.01%, which was 2.51 percentage points above the rate offered on certain other savings accounts.
These remain allegations made by the plaintiff. There has been no court finding that HDFC Bank or its executives violated securities laws or banking regulations.
HDFC Bank has rejected the case. A spokesperson described such shareholder actions as common in the US following share-price declines and said the bank believes the lawsuit is without merit. The lender intends to defend itself vigorously.
Earlier Governance Questions Return to Focus
The HDFC Bank lawsuit follows months of scrutiny surrounding the institution’s internal governance.
Reports in May alleged that an internal vigilance investigation examined payments connected with the MSRDC deposits and identified responsibility among several senior employees. The lawsuit relies partly on those reports when making its claims against the lender and its executives.
The issue gained further attention after former chairman Atanu Chakraborty resigned in March. In his resignation letter, he referred to practices within the bank that he said did not align with his personal values and ethics.
HDFC Bank subsequently appointed US law firm Wilson Sonsini Goodrich & Rosati and Indian firm Wadia Ghandy & Co to conduct an independent legal review. The review found no evidence supporting the former chairman’s allegations, according to the bank.
The legal action in New York is separate from that internal review. Its filing does not prove the allegations, and the case must proceed through the US court process before any liability can be established.
The plaintiff is seeking compensatory damages, interest and legal costs on behalf of the proposed investor class. The value of any potential claim has not been determined.
HDFC Bank’s American depositary shares trade on the New York Stock Exchange, giving US investors access to the Indian lender and bringing its investor disclosures within the scope of American securities laws.
CEO Renewal Adds Another Layer of Uncertainty
Market attention is also turning towards the future of managing director and chief executive Sashidhar Jagdishan, whose current term expires in October.
No final decision about his reappointment has been announced. The length and terms of any extension will require the necessary corporate and regulatory approvals.
Macquarie said a short-term extension could continue to weigh on the stock because it would leave questions about leadership unresolved. A three-year renewal, by contrast, could provide greater clarity.
Leadership continuity matters because HDFC Bank is still managing the operational and financial effects of its merger with Housing Development Finance Corporation. The transaction substantially increased the bank’s balance sheet but also changed its funding structure.
The lender has been working to improve its deposit growth, loan-to-deposit ratio and profitability following the merger. Any prolonged management uncertainty could make it harder for the market to assess how that strategy will progress.
Investors are also watching allegations concerning the reported sale of Carlisle’s Luxembourg Life Fund through the bank’s Dubai operations. Complaints relating to losses and delayed redemptions have added to the concerns surrounding customer protection and oversight.
These matters remain separate from the US class action, and their inclusion in market discussions does not establish wrongdoing by the bank.
Heavyweight Stock Pulls Down Benchmarks
HDFC Bank’s size magnified Thursday’s market reaction. A substantial movement in the stock can influence the Nifty and Sensex even when several other large companies are trading higher.
The wider market had initially received support from lower crude prices and gains across Asian technology stocks. Brent crude remained near $88 per barrel, easing some concern for an economy that imports most of its oil.
Those positive cues were not enough to offset weakness in the banking heavyweight. Eleven of the 16 major domestic sector indices finished lower.
ICICI Prudential Asset Management Company also dropped about 4% after promoter Prudential Plc sold a 2% stake to meet shareholding requirements.
The immediate focus for HDFC Bank stock will remain on the lender’s response to the US complaint and any formal announcement concerning Jagdishan’s tenure.
At ₹710, the shares have reached their lowest level in 29 months after falling for three consecutive sessions. The bank denies the lawsuit’s claims, and no liability has been established, but the combination of legal proceedings and leadership uncertainty has increased pressure on one of India’s most influential listed companies.
