IDBI Bank on Saturday, 17 October 2026 reported a 39.2 per cent year-on-year decline in net profit to ₹2,206 crore for the second quarter of FY27, compared to ₹3,627 crore in the same period a year ago. The bank attributed the sharp fall primarily to a high base effect from the previous year, which had included a one-time gain of ₹1,699 crore from the sale of its strategic investment in the National Securities Depository Limited (NSDL).
The Base Effect Explained
Stripped of the one-off NSDL divestment gain from the year-ago quarter, the bank's underlying net profit actually grew 14 per cent year-on-year, according to the bank's own disclosure. On a sequential basis, profit climbed approximately 4 per cent from ₹2,115 crore recorded in the April–June 2026 quarter — signalling steady operational momentum beneath the headline noise.
Core Income and Margin Expansion
Net interest income (NII) surged 28.7 per cent year-on-year to ₹4,227 crore, up from ₹3,285 crore a year earlier, and rose 21 per cent quarter-on-quarter from ₹3,486 crore. The net interest margin (NIM) widened to 4.11 per cent from 3.71 per cent a year ago — an expansion of 40 basis points year-on-year — and improved 50 basis points sequentially from 3.61 per cent in Q1 FY27. Operating profit stood at ₹2,893 crore, up 33 per cent quarter-on-quarter; excluding the prior-year NSDL gain, operating profit rose 59 per cent year-on-year.
Balance Sheet Strength and Efficiency Gains
Total deposits grew 17 per cent year-on-year to ₹3,55,684 crore from ₹3,03,408 crore, while net advances rose 18 per cent to ₹2,71,533 crore from ₹2,30,220 crore. Sequentially, deposits were up 9 per cent and advances 5 per cent. CASA deposits rose 12 per cent year-on-year to ₹1,55,877 crore, with the CASA ratio at 43.82 per cent, up 18 basis points sequentially. The cost-to-income ratio improved to 48.17 per cent, down 385 basis points sequentially, while the cost of deposits eased to 4.55 per cent from 4.69 per cent year-on-year.
Fairfax Stake Sale and Share Price Impact
The results arrive days after a significant ownership development: the Union Cabinet earlier in the week approved the sale of a 60.72 per cent stake in IDBI Bank to Fairfax Financial Holdings for ₹52,878 crore at ₹81 per share. The announcement triggered a sharp market reaction — the stock fell over 7 per cent on Thursday post-announcement before closing at ₹84.11 on the BSE on Friday. The share has declined approximately 19 per cent year-to-date, reflecting broader investor caution around the privatisation trajectory. With the Fairfax deal now in motion and core operating metrics trending upward, the bank's next quarterly performance will be closely watched for signs of sustained earnings recovery.
Point of View
But it is almost entirely a statistical artefact of last year's NSDL windfall — the underlying business is actually growing. What deserves more scrutiny is the Fairfax deal: the Cabinet-approved price of ₹81 per share is below the current market price of ₹84, yet the stock has still shed 19% year-to-date, suggesting the market is pricing in execution risk or dilution concerns around the privatisation structure. IDBI Bank's NIM expansion to 4.11% is genuinely impressive for a bank of its vintage, but whether that holds post-ownership change — when strategy and liability management could shift — is the real open question that quarterly results alone cannot answer.
