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.
How it worked
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
- Line 1 — Treasury and Finance. The people originating, recording and accounting for transactions.
- Line 2 — Risk, Compliance and Internal Controls. The functions expected to independently challenge unusual positions, unexplained balances and reconciliation differences.
- Line 3 — Internal and External Audit. The final independent challenge to whether the financial statements reflect economic reality.
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.
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.
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.
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:
- When was the last time someone asked why the difference existed at all?
- How old is the oldest unreconciled difference?
- Who signs off unresolved exceptions?
- Can an internal trade generate reported profit?
- What testing was performed around early terminations?
- How did the unreconciled position evolve over time?
Only after answering those questions should the committee discuss the technical accounting treatment. Because complexity should never become camouflage.
Early Warning Signals
- Long-standing reconciliation differences repeatedly carried forward.
- Inconsistent accounting treatment between internal desks for the same transaction.
- Material balances sitting in vague categories such as "Other Assets" or "Other Liabilities."
- Profit arising from transactions conducted entirely between units of the same legal entity.
- Accounting explanations that cannot be translated into straightforward economic terms.
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?
