Mumbai | The investigation into alleged irregularities of nearly ₹2,000 crore in derivatives transactions linked to IndusInd Bank has intensified, with authorities expanding the scope of the probe. The Serious Fraud Investigation Office (SFIO) has now summoned major audit firms associated with the bank over the past decade, signaling a broader examination of accountability beyond internal management.
According to sources, the probe is no longer confined to former bank officials. Investigators are now closely assessing whether there were lapses in oversight, reporting, or compliance during the audit process. This shift is seen as a crucial step toward fixing responsibility in a case that raises serious concerns about financial governance in large institutions.

Focus shifts to audit firms
The investigation is expected to involve detailed questioning of several prominent audit firms that reviewed the bank’s financial statements over the years. Authorities aim to determine whether risks linked to the derivatives portfolio and potential losses were identified and flagged in time.
Sources indicate that the questioning process may accelerate in the coming days, with a key phase likely to conclude by the end of April. So far, there has been no formal public response from the audit firms involved.
₹2,000 crore impact raises red flags
The issue first came to light in March 2025, when the bank disclosed discrepancies in its derivatives transactions. Initial estimates suggested a one-time financial impact of around ₹2,000 crore, significantly affecting its financial results.
Further findings suggest that these irregularities accumulated gradually over a period of five to seven years. This has raised critical questions about how such discrepancies persisted undetected for so long and whether internal control mechanisms were robust enough to identify early warning signs.
Former officials already questioned
As part of the investigation, authorities have already questioned several former senior officials of the bank. These interactions focused on understanding the nature of derivatives deals, risk management practices, and accounting procedures followed during the period under scrutiny.
The central objective is to establish whether the issue stems from procedural lapses or involves deliberate manipulation. If elements of fraud are established, strict legal action under corporate laws could follow.
Forensic review of records underway
Investigators are currently examining a wide range of documents, including audit reports, forensic analyses, internal inspection records, and statutory filings. Particular attention is being paid to reports that may have indicated potential fraud or financial inconsistencies.
The probe is also exploring whether there was manipulation of accounts, creation of fictitious entries, or misclassification of assets that may have distorted the bank’s true financial position.
Corporate governance concerns deepen
The case has triggered a broader debate on corporate governance standards within the banking sector. Experts believe that complex financial instruments such as derivatives require strong monitoring frameworks and proactive risk assessment systems.
Any weakness in these mechanisms can allow risks to remain hidden for years, eventually surfacing as major financial shocks. The developments in this case underline the need for stricter audit scrutiny and enhanced transparency in financial reporting.
What lies ahead
The next phase of the investigation will be crucial, as authorities work to determine the role and accountability of audit firms. If serious negligence or collusion is uncovered at any level, it could lead to significant legal and regulatory consequences.
For now, the case highlights a tightening stance on transparency and accountability in financial institutions. More revelations are expected in the coming weeks, which could have far-reaching implications for the banking sector and its regulatory oversight framework.
