The Numbers Reconciled. Until They Didn't.

Nearly ₹2,000 crore of adverse accounting impact, two senior resignations, and a control question far simpler than the accounting that hid it.

Why This Matters

If two internal desks in the same institution can account for the same transaction differently — and the resulting discrepancy can grow materially before being corrected — how many controls did the error pass through?

Last edition, the failure could be found by counting cars

This time, it could be found by reconciling two books. The accounting was more complicated. The control principle wasn't.

IndusInd Bank undertook internal derivative transactions between different desks within the bank. Economically, an internal transaction cannot create profit for the bank as a whole merely because one internal desk records something differently from another — one desk's gain should ultimately meet another desk's corresponding position.

Derivatives make the accounting look complicated. The first control question is simpler: why did two sides of an internal transaction produce an economic result that did not reconcile?

A bank cannot create real profit simply by trading with itself.

According to the independent investigation commissioned by the bank's board, incorrect accounting of internal derivative trades — particularly where trades were terminated early — resulted in the recording of notional profits. The bank said it would appropriately reflect the impact in its FY2024–25 financial statements and strengthen internal controls.

The number is dramatic. The control failure behind it is the real story.

The first red flag wasn't ₹1,960 crore

In March 2025, IndusInd Bank disclosed discrepancies relating to balances in its derivatives portfolio. Its initial internal review estimated an adverse impact equivalent to approximately 2.35% of the bank's net worth as of December 2024. An external review subsequently quantified the impact differently, and the board commissioned an independent investigation, which submitted its report on 26 April 2025.

Its conclusion was significant: the principal root cause was incorrect accounting of internal derivative trades, especially in cases of early termination, resulting in the recording of notional profits. The board said the investigation also examined the roles and actions of key employees. That changes the nature of the story — this was no longer merely "was an accounting entry wrong?" The question became: why didn't the control environment correct it earlier?

The three lines of defence

Financial institutions are supposed to operate with multiple layers of control. So where should a discrepancy like this have surfaced?

The Control Layers

When a discrepancy survives long enough to become material, the interesting question isn't which individual entry was incorrect. It is: how many controls did the entry pass through before somebody challenged it?

Then management changed

The accounting issue did not end with a financial adjustment.

Mar 2025 Discrepancies disclosed. IndusInd Bank discloses discrepancies relating to balances in its derivatives portfolio; an initial internal review estimates the impact at roughly 2.35% of net worth as of December 2024.
26 Apr 2025 Investigation report. The board-commissioned independent investigation submits its findings: incorrect accounting of internal derivative trades, particularly on early termination, led to notional profits.
28 Apr 2025 Deputy CEO resigns. Arun Khurana, who oversaw the Treasury Front Office function, resigns, referring in his resignation to the adverse accounting impact.
29 Apr 2025 CEO resigns. Managing Director & CEO Sumant Kathpalia resigns, saying he was taking moral responsibility in relation to the derivatives matter.

That sequence matters. Accounting failures become governance failures when the problem moves from "what number is correct?" to "who was responsible for ensuring it was correct?"

The story did not end there.

Q4 FY25 The loss lands. IndusInd Bank reports a net loss of ₹2,329 crore for the January–March 2025 quarter, after provisioning for and reversing the incorrectly booked entries.
2 Jun 2025 Reported to SFIO. Under RBI's fraud-reporting rules, the bank reports the derivative, "other assets/liabilities," and microfinance income matters to the SFIO.
Nov 2025 New leadership. Rajiv Anand takes over as MD & CEO; the bank reports a further net loss as loan and deposit books shrink, and the board looks to claw back salary and bonuses paid to former senior officials.
Dec 2025 SFIO formalises its probe; EOW steps back. The Ministry of Corporate Affairs directs the SFIO to investigate under Section 212 of the Companies Act. Separately, Mumbai Police's Economic Offences Wing — which had been examining the matter since August — moves to close its preliminary inquiry, reportedly finding no evidence of fund misappropriation or diversion.
Mar 2026 Scope widens, individuals summoned. Reporting describes the cumulative figure under review growing to roughly ₹1,979 crore as additional items are examined — including microfinance income and fee-income entries beyond the original derivatives discrepancy. The SFIO summons former CEO Sumant Kathpalia, former CFO Gobind Jain, and former Deputy CEO Arun Khurana; the bank's current management has said the former leadership caused wrongful loss to the institution.
Where The Matter Stands Today

As of this edition, the SFIO's Section 212 investigation remains open and no court or tribunal has adjudicated findings of fraud against any individual named in this article; the Economic Offences Wing's preliminary inquiry, separately, has reportedly been closed without findings of fund misappropriation. The ₹1,959.98 crore figure discussed throughout this article is the derivatives-related impact identified in the investigation report submitted to the bank's board on 26 April 2025. Subsequent reporting describes a wider set of accounting questions — spanning microfinance income and fee-income entries — that sit outside the scope of this article and are not addressed here.

The Uncomfortable Footnote

Companies often describe internal controls using reassuring language — processes, maker-checker systems, reconciliations, risk committees, internal audits, external audits, board committees. But the existence of a control is not evidence that the control works. A reconciliation prepared every month is worthless if unexplained differences simply roll forward. A committee meeting is worthless if unusual balances are presented but never challenged.

Complex accounting does not require fewer basic questions. It requires more of them.

The question an Audit Committee should ask

Imagine sitting on the Audit Committee. Management tells you: "This is a technical accounting issue involving internal derivative transactions." What do you ask next? Not "which accounting standard applies?" — start with the reconciliation itself.

If You Were on the Audit Committee…

Would you have asked:

Only after answering those questions should the committee discuss the technical accounting treatment. Because complexity should never become camouflage.

Early Warning Signals

Governance Principle #10

Unreconciled differences are information.

Reconciliation isn't about making two numbers agree. It's about discovering why they don't. The longer a difference survives, the more important the question becomes: who knew it was there?

The real lesson

Edition 09 was almost embarrassingly simple. ₹978 crore was raised for EVs. 6,400 vehicles were supposed to be procured. Only 4,704 were disclosed as having been procured. Someone needed to count the cars.

IndusInd Bank looks completely different — derivatives, treasury operations, early termination, accounting methodologies, mark-to-market calculations. Yet beneath all that sophistication sits almost exactly the same question: did anybody independently check whether what should have been there was actually there? At Gensol, count the vehicles. At IndusInd, reconcile the books. Different companies, different industries, same control principle.

And the principle travels well beyond banking. The same problem can arise wherever an organisation maintains two systems that describe the same event — bank versus ledger, inventory versus ERP, GST returns versus books, loan records versus the general ledger, subsidiary accounts versus consolidated accounts. The accounting subject changes. The control principle doesn't.

Final Footnote

Financial scandals make accounting look extraordinarily complicated. Often the first warning sign isn't. Count the inventory. Confirm the cash. Reconcile the bank. Match the related parties. Trace the money. And when two numbers that should agree don't agree — don't explain the difference away. Find out why.

Every governance failure leaves behind a red flag.

The question is whether someone noticed it in time.

Next: Edition 11 opens another file. Same series. Same question. How did nobody see it?
