IDBI Bank reported a 39% year-on-year decline in net profit to ₹2,205 crore for the second quarter of financial year 2026–27, as lower other income weighed on its earnings. The bank’s profit for the quarter ended September 30, 2026, compared with ₹3,627 crore in the corresponding period last year. The main reason for the decline was the absence of a one-time ₹1,699 crore gain from the sale of its stake in the National Securities Depository Ltd (NSDL), which had boosted the year-ago results.
Despite the headline decline, IDBI Bank reported growth in several core banking indicators. Net interest income increased 29% to ₹4,228 crore, net interest margin improved to 4.11%, advances rose 18% and deposits grew 17%. The results came days after the government approved the sale of a combined 60.72% stake in IDBI Bank to Canada’s Fairfax Financial Holdings for ₹52,878 crore, placing the lender’s performance under additional scrutiny as it prepares for a potential change in ownership.

Why Did IDBI Bank’s Q2 Profit Fall 39%?
The main factor behind IDBI Bank’s reported profit decline was a high comparison base from the previous financial year. In the September 2025 quarter, the bank recorded a one-time gain of ₹1,699 crore from selling a stake in NSDL.
That gain increased the previous year’s other income and made the year-on-year comparison more difficult. In the September 2026 quarter, the bank did not receive an equivalent gain, causing reported non-interest income to decline.
The distinction matters because a one-time transaction can lift a company’s earnings in a particular period without necessarily reflecting the performance of its recurring business. When that gain does not recur, reported profit may fall even if the underlying operation continues to expand.
IDBI Bank said that after adjusting for the exceptional gain in the year-ago period, net profit increased 14% year-on-year. This adjusted comparison provides a different view of the quarter, although investors should consider both the reported figures and the bank’s explanation.
Reported profit versus adjusted profit
| Metric | Q2 FY26 | Q2 FY27 |
|---|---|---|
| Reported net profit | ₹3,627 crore | ₹2,205 crore |
| One-time NSDL-related gain in the year-ago quarter | ₹1,699 crore | No comparable gain |
| Net profit excluding the prior-year one-off, for comparison | ₹1,929 crore | ₹2,205 crore |
| Adjusted year-on-year profit change | — | Approximately 14% growth |
Figures are rounded. The adjusted comparison removes the reported one-time gain from the earlier period; it is not a replacement for the bank’s reported net profit.
The headline decline therefore needs context. The bank earned less than it did in the unusually strong year-ago quarter, but the adjusted comparison suggests that recurring earnings improved.
Other Income and Operating Profit Remain Under Pressure
IDBI Bank’s non-interest income fell 46% year-on-year to ₹1,353 crore in the September 2026 quarter, compared with ₹2,489 crore a year earlier.
Other income can include fees, commissions, treasury-related earnings and gains from financial investments. Its performance can vary depending on market conditions, transaction activity and one-off events.
The absence of the NSDL-related gain had a substantial effect on this category. As a result, operating profit declined 18% year-on-year to ₹2,893 crore from ₹3,523 crore.
The decline in operating profit illustrates why a strong increase in interest income does not automatically translate into higher total earnings. Other income and operating expenses also influence the final result.
For investors, the key question is whether the bank can sustain growth in its core lending business while managing expenses and limiting dependence on irregular gains.
Net Interest Income Rises 29%
Net interest income (NII) is the difference between the interest a bank earns on loans and investments and the interest it pays on deposits and borrowings. It is one of the most important indicators of a bank’s recurring lending performance.
IDBI Bank’s NII increased 29% year-on-year to ₹4,228 crore from approximately ₹3,285 crore in the same quarter last year.
The increase suggests that the bank generated more net interest revenue from its banking activities. Growth in advances can support NII, although deposit costs, loan pricing and changes in the composition of the balance sheet also influence the result.
The improvement in NII was accompanied by a rise in net interest margin, indicating that the bank earned more net interest relative to its interest-earning assets.
Net interest margin improves to 4.11%
Net interest margin (NIM) measures the net interest income earned relative to interest-earning assets. It helps investors assess how effectively a bank generates interest income from its lending and investment operations.
IDBI Bank’s NIM increased to 4.11% in Q2 FY27 from 3.71% a year earlier.
| Banking indicator | Q2 FY26 | Q2 FY27 |
|---|---|---|
| Net interest income | ₹3,285 crore | ₹4,228 crore |
| Net interest margin | 3.71% | 4.11% |
| Year-on-year NII growth | — | 29% |
The improvement is encouraging for the bank’s recurring income profile. However, NIM can change as interest rates move, deposit pricing shifts and the mix of loans and investments evolves. Sustaining the improvement will depend on the bank’s ability to manage funding costs and maintain loan yields.
Advances and Deposits Continue to Expand
IDBI Bank also reported growth in both lending and deposits during the quarter. Net advances increased 18% year-on-year to approximately ₹2.71 lakh crore, compared with ₹2.30 lakh crore in September 2025.
Deposits rose 17% to ₹3.55 lakh crore from ₹3.03 lakh crore a year earlier. Growth in deposits provides a larger funding base for the bank’s lending operations, although the cost of attracting and retaining deposits remains important for profitability.
| Business metric | September 2025 | September 2026 | Year-on-year change |
|---|---|---|---|
| Net advances | ₹2.30 lakh crore | ₹2.71 lakh crore | +18% |
| Total deposits | ₹3.03 lakh crore | ₹3.55 lakh crore | +17% |
The parallel growth in advances and deposits indicates that the bank expanded both sides of its core banking business. Investors will nevertheless want to see whether this growth produces sustainable interest income without weakening credit standards or increasing funding costs.
Loan growth alone is not enough to establish stronger profitability. Banks must also assess borrowers’ repayment capacity, price credit appropriately and maintain sufficient provisions against potential losses.
Operating Expenses Increase 19%
IDBI Bank’s operating expenses increased 19% year-on-year to ₹2,688 crore from ₹2,252 crore.
Operating expenses cover the costs of running the bank, including employee expenses, administrative costs, technology, branches and other operating activities. An increase can reflect business expansion, inflation or additional spending, but it can also place pressure on profitability if income does not grow at a faster pace.
In IDBI Bank’s case, the 29% increase in net interest income was stronger than the 19% increase in operating expenses. However, the drop in other income and the absence of the exceptional NSDL gain pulled down reported operating profit.
The bank will need to balance business growth with cost discipline as it develops its lending operations and prepares for the proposed ownership transition.
Investors will also monitor the cost-to-income ratio, which compares operating expenses with operating income. A lower ratio generally indicates that a bank is spending less to generate each unit of operating income, although differences in business models and income composition must be considered.
Asset Quality Remains a Key Strength
Asset quality measures how well a bank manages loans and controls bad debts. Two commonly watched indicators are gross non-performing assets (gross NPAs) and net non-performing assets (net NPAs).
IDBI Bank’s net NPA ratio was 0.17% in September 2026, compared with 0.21% a year earlier. The gross NPA ratio was reported at 2.12%, down from 2.30% in the preceding quarter.
The low net NPA ratio indicates that the bank’s remaining bad loans, after accounting for provisions, represented a relatively small share of net advances. However, the direction of the gross NPA ratio, new slippages, recoveries and provision coverage remain important for assessing credit risk.
Asset quality is especially relevant when a bank is expanding its loan book. Faster lending can support revenue, but the long-term benefit depends on whether borrowers repay as expected.
For IDBI Bank, stable asset quality alongside growth in advances and deposits provides a useful counterpoint to the decline in reported quarterly profit.
Fairfax Deal Adds a New Dimension to IDBI Bank’s Outlook
The Q2 results were announced shortly after the government approved the sale of a combined 60.72% stake in IDBI Bank to Fairfax Financial Holdings for ₹52,878 crore.
The transaction involves stakes held by the Government of India and the Life Insurance Corporation of India (LIC). It represents a major step in the bank’s proposed privatisation, although the deal remains subject to the applicable regulatory conditions and completion process.
For the prospective new owner, the quarterly results provide information about the bank’s earnings profile, deposit base, lending growth, operating costs and asset quality. The adjusted profit increase and improvement in NIM point to progress in core banking operations, while the increase in expenses and decline in reported operating profit remain areas to watch.
The ownership change does not automatically guarantee improved financial performance. Any future gains will depend on management decisions, business strategy, competition, regulatory requirements and the bank’s ability to sustain profitable growth.
Customers should also distinguish the proposed ownership transition from immediate changes to their accounts or services. Any operational changes would depend on formal announcements and subsequent decisions by the bank.
The Bigger Picture
IDBI Bank’s Q2 results show why reported profit growth can be distorted by one-time gains. The 39% fall in net profit appears steep, but the previous year’s ₹1,699 crore NSDL-related gain materially inflated the comparison. Excluding that gain, the bank reported 14% year-on-year profit growth, supported by stronger net interest income and an improved NIM.
At the same time, the results highlight the need to examine the full banking performance rather than focusing on a single metric. Advances and deposits grew, while asset quality remained relatively stable. Higher operating expenses and weaker other income, however, show that the bank still needs to balance growth with cost management as it approaches a potential change in ownership.
Looking Ahead
Investors will watch whether IDBI Bank can sustain its improvement in net interest income and margins while keeping operating expenses under control. Deposit growth, loan quality, recoveries and the mix of recurring and non-recurring income will remain important in the coming quarters. The adjusted profit comparison is useful, but future performance will depend on the bank’s ability to generate earnings without relying on exceptional transactions.
The proposed Fairfax acquisition adds another layer to the outlook. Once the applicable approvals and closing steps are completed, the new ownership structure could influence the bank’s strategy and long-term priorities. Until then, the Q2 figures provide a snapshot of the business as it stands: reported profit declined sharply because of a high base, while several core lending indicators continued to improve.
