MUMBAI: Serious Fraud Investigation Office (SFIO) has opened a formal probe into IndusInd Bank after a Dec 23, 2025 letter triggered an investigation under the Companies Act, 2013, over accounting lapses tied to internal derivative trades.In a filing, the bank said SFIO, under the MCA, seeks information after the lender flagged on June 2 issues spanning internal derivatives, unsubstantiated “other assets/liabilities”, and microfinance interest/fee income. It disclosed the update on Dec 18, pledged full cooperation, and posted details on its website.Derivatives irregularities have hit P&L by about Rs 1,960 crore as of March 31, 2025, eroding reported net worth by roughly 2.3% as of Dec 2024. Earlier profits were overstated as notional gains flowed into P&L while losses sat parked as assets, inflating NII and earnings quality. The derivatives irregularities saw several members of the senior management stepping down with the board bringing in Rajiv Anand from Axis Bank to head the private lender.The bank recognised the losses, absorbed pain in its FY25 earnings which tipped the bank into a Q4 FY25 net loss after one-off write-offs/provisions. Capital/net worth took a 2–2.5% post-tax hit, trimming buffers and nudging growth appetite and capital pricing.The derivatives loss resulted in the shares of the bank sliding as investors reassessed earnings credibility and governance. The scrutiny also sharpened on the board/management/audit committees, intensifying regulatory pressure and SFIO oversight.
