SFIO investigates IndusInd Bank derivatives accounting discrepancy

IndusInd Bank Ltd., one of India's larger private-sector lenders, is under a statutory investigation by the Serious Fraud Investigation Office (SFIO) following an accounting discrepancy in its internal derivatives portfolio that the bank itself first disclosed. This is an investigation-stage matter on the weakest possible footing: no person has been named as an accused, no first information report (FIR) has been registered, and no court or regulator has recorded any finding of wrongdoing.

What the Record Shows

The Ministry of Corporate Affairs (MCA) formally ordered the SFIO to investigate the affairs of IndusInd Bank in late December 2025, citing public interest. The order followed the bank's own disclosure in March 2025 that an internal review had identified a discrepancy of about Rs 1,979 crore in the accounting of its derivatives book, accumulated over several years.

Under the Reserve Bank of India's Master Directions on Fraud Risk Management in Commercial Banks, which require a private-sector bank to report any suspected fraud of Rs 1 crore or more to the SFIO in addition to the police, IndusInd reported the derivatives matter, and separately identified irregularities in its microfinance accounting, to the SFIO on 2 June 2025. Reporting under that framework is a mandatory compliance step, not an admission that a fraud occurred.

The SFIO has since summoned former key managerial personnel of the bank, including former Managing Director and Chief Executive Sumant Kathpalia, former Deputy Chief Executive Arun Khurana and former Chief Financial Officer Gobind Jain, for questioning. Being summoned to give information is not the same as being accused. Importantly, the Mumbai Police Economic Offences Wing found that there was no evidence of siphoning or diversion of funds and was preparing to close its inquiry without registering an FIR, an exculpatory position that sits at the centre of the current record.

How It Worked

The mechanism, as described in the bank's own disclosures and the external reviews it commissioned, concerns the internal accounting of derivative trades rather than any dealing with customers. Over a period of several years, gains on internal derivative transactions within the bank's own books were, on the bank's later assessment, recognised in a way that did not reflect economic reality. When the treatment was re-examined, a cumulative shortfall of about Rs 1,979 crore surfaced. The bank characterised this as a discrepancy identified through its own internal review and an external assessment.

The sequence on the public record runs as follows. In March 2025 the bank disclosed the derivatives discrepancy to the stock exchanges. In April 2025 the Chief Executive, Sumant Kathpalia, and the Deputy Chief Executive, Arun Khurana, resigned. On 2 June 2025 the bank reported the derivatives matter and the separately identified microfinance irregularities to the SFIO under the RBI framework. Press estimates have put the combined exposure across the two books at roughly Rs 2,600 crore, though the bank's disclosed derivatives figure is Rs 1,979 crore.

In late December 2025 the MCA ordered the SFIO to investigate the affairs of the bank. An SFIO investigation is an examination of a company's affairs: it gathers documents and records statements, and it may or may not lead to a prosecution. The summonses issued to former executives are part of that fact-gathering. No charge sheet has been filed, and the investigation is continuing.

Who Lost Money

The people most directly affected on the record are the bank's shareholders. When the derivatives discrepancy was disclosed in March 2025, IndusInd's share price fell sharply, reducing the market value held by institutional and retail investors alike. That fall, rather than any established loss of customer money, is the concrete financial consequence documented so far.

Depositors were not shown to have lost money. The RBI publicly reassured depositors that the bank remained well-capitalised, and the bank continued to operate normally throughout. No depositor has been shown on the record to have lost money, and the Mumbai Police Economic Offences Wing found that there was no evidence funds were siphoned or diverted.

Because the matter concerns internal accounting rather than a pool of investor money collected on a false promise, there is no victim-compensation or recovery distribution of the kind seen in deposit-scheme cases. What is at stake is the accuracy of the bank's past financial statements and the accountability of those who oversaw them, both of which the investigation is examining.

Where It Stands Now

As of today, the matter rests at the investigation stage. The SFIO investigation ordered by the MCA in December 2025 is continuing, and the agency has summoned former key managerial personnel for questioning. No charge sheet has been filed against any individual, no FIR has been registered, and no court or regulator has recorded a finding of wrongdoing. The Mumbai Police Economic Offences Wing was reported to be moving to close its inquiry, having found that there was no evidence of siphoning or diversion.

An SFIO investigation, a police inquiry and any regulatory examination each contain lines of inquiry, not findings of guilt; the individuals summoned are presumed innocent until proven guilty, and due process continues. The former executives who resigned in April 2025 have not been charged with any offence, and a summons to assist an investigation carries no adverse finding.

IndusInd Bank has said it disclosed the discrepancy on its own initiative, reported it as required and cooperated with the authorities. The former executives named have the right to place their responses on the record through the ordinary channels, and this report will reflect any that they make. The position may change as the SFIO completes its work.

What It Means

The IndusInd matter shows how the bank-fraud reporting framework is designed to work upstream of any court. Under the RBI's 2024 Master Directions, a private-sector bank that identifies a suspected fraud of Rs 1 crore or more must report it to the SFIO as well as the police, regardless of whether wrongdoing is ultimately established. The referral is a mandatory tripwire, not a verdict, which is why a report to the SFIO should not be read as an admission by the bank.

Recent enforcement actions in the banking and housing-finance space, such as the RBI's supersession of the Aviom Housing Finance board and its cancellation of Karnala Sahakari Bank's licence, show the range of tools available once concerns surface, from board action to licence cancellation to statutory investigation. Readers can follow the wider enforcement trail through the Oquilia enforcement archive.

For an ordinary shareholder or depositor, the practical takeaway is about where to look for reliable information. A bank's disclosures to the stock exchanges and the RBI's own statements are the authoritative record of solvency and capital; market rumour is not. When a discrepancy is disclosed, the RBI's public assessment of whether the bank remains well-capitalised is the signal that matters for deposit safety. Nothing here is a comment on the conduct of any individual, which remains under investigation; the value of the episode is procedural, showing that disclosure, mandatory reporting and independent investigation are the mechanisms by which an accounting question is tested.

FAQ

Does the SFIO investigation mean the people named are guilty?

No. An SFIO investigation, a police inquiry and the summonses issued so far contain lines of inquiry, not findings of guilt. The former executives who have been summoned are presumed innocent unless and until a competent court holds otherwise, and due process is continuing. No charge sheet has been filed and no FIR has been registered.

What exactly has the SFIO been asked to do?

The Ministry of Corporate Affairs ordered the SFIO in December 2025 to investigate the affairs of IndusInd Bank in the public interest. The SFIO gathers documents, examines the bank's accounts and records statements from relevant persons. Such an investigation may lead to a prosecution or may close without one; at this stage it has done neither.

Did depositors lose money?

No depositor has been shown on the record to have lost money. The RBI publicly stated that the bank remained well-capitalised, and it continued normal operations throughout. The documented financial impact so far has fallen on shareholders, whose holdings lost value when the share price fell after the March 2025 disclosure.

Why did the bank itself report the matter?

Under the RBI's Master Directions on Fraud Risk Management, a private-sector bank must report any suspected fraud of Rs 1 crore or more to the SFIO and the police. IndusInd reported the derivatives and microfinance matters under that rule on 2 June 2025. Reporting is a mandatory compliance step and is not, by itself, an admission that a fraud occurred.

Has any agency found that funds were siphoned?

No. The Mumbai Police Economic Offences Wing found that there was no evidence of siphoning or diversion of funds, and it was reported to be preparing to close its inquiry without registering an FIR. The SFIO investigation into the accounting treatment is separate and remains open.

Where can I read the official framework?

The reporting obligation is set out in the RBI's Master Directions on Fraud Risk Management in Commercial Banks (Including Regional Rural Banks) and All India Financial Institutions dated 15 July 2024, published on the RBI website.

This report is based on the RBI Master Directions on Fraud Risk Management in Commercial Banks dated 15 July 2024, the bank's own disclosures to the stock exchanges, and the position of the investigating agencies reviewed on 2 August 2026.
