South Indian Bank ends FY26 with best-ever profit and sharper asset quality

South Indian Bank closed Q4 FY26 with a cleaner balance sheet, steadier operating execution, and another quarter of profitability that reflects the bank’s ongoing transformation. For the quarter ended March 31, 2026, profit after tax rose to Rs. 408 crore from Rs. 342 crore in Q4 FY25, a year-on-year increase of 19 percent. Profit before tax increased 19 percent year on year to Rs. 547 crore. For the full year FY26, the bank reported its best-ever net profit of Rs. 1,455 crore, up 12 percent from Rs. 1,303 crore in FY25.

The quarter’s total income came in at Rs. 1,301 crore versus Rs. 1,440 crore a year ago, while net interest income rose 5 percent to Rs. 915 crore. The headline profitability uplift was supported by materially lower provisioning. Provisions and contingencies fell to Rs. 34 crore in Q4 FY26 from Rs. 224 crore in Q4 FY25, reflecting the sharp improvement in asset quality metrics and credit cost. The bank’s stated theme, closing strong and building ahead, is visible in the combination of growth, risk control, and continued investment in systems, processes, and staff capabilities.

A key part of the FY26 narrative is that the bank delivered best-ever annual totals across several operating and profitability lines. Total income for FY26 stood at Rs. 5,447 crore, other income at Rs. 2,010 crore, and pre-provision operating profit at Rs. 2,373 crore. The bank also reported a provision coverage ratio including write-offs of 94.10 percent at March 2026, its highest level in the period shown.

Growth with a shifting loan mix

South Indian Bank’s operating scale expanded meaningfully over the year. Gross advances increased to Rs. 100,274 crore in Q4 FY26 from Rs. 87,579 crore in Q4 FY25, a year-on-year growth of 14.5 percent. The bank noted that this includes a technical write-off of Rs. 1,163 crore, and excluding this, the year-on-year growth is 15.8 percent. Deposits grew 15 percent to Rs. 123,346 crore from Rs. 107,526 crore, with retail deposits rising to Rs. 120,116 crore from Rs. 104,750 crore.

The most important directional change continues to be the loan book mix. The bank is steadily shifting from corporate-heavy growth to a more granular portfolio anchored in retail and MSME. In Q4 FY26, corporate loans accounted for 38 percent of the loan book, down from 41 percent in Q4 FY25. The personal segment rose to 29 percent from 26 percent, while agriculture remained steady at 19 percent and business loans at 14 percent.

Within retail, the personal segment advanced to Rs. 28,901 crore in March 2026 from Rs. 22,405 crore in March 2025, a growth of 29 percent. Gold loans were a major driver, with gold including agriculture rising 46 percent year on year to Rs. 24,729 crore from Rs. 16,982 crore. Mortgage loans grew 43 percent to Rs. 5,435 crore from Rs. 3,814 crore. Auto loans also grew 21 percent to Rs. 2,412 crore from Rs. 1,987 crore, while home loans were broadly flat to slightly lower, at Rs. 7,793 crore versus Rs. 7,877 crore.

MSME remains a focus area, positioned as a higher-yielding and more granular book. MSME and SME outstanding stood at Rs. 9,269 crore in March 2026 versus Rs. 9,698 crore in March 2025, alongside an increase in the others category to Rs. 4,509 crore. Total MSME loans were Rs. 13,778 crore in March 2026 versus Rs. 12,686 crore in March 2025. The bank noted that the March 2026 figure includes a write-off of Rs. 554 crore and that excluding this, year-on-year growth is 13 percent.

The corporate book, meanwhile, remained stable in size and strengthened in quality. Corporate advances rose modestly to Rs. 38,670 crore in March 2026 from Rs. 36,198 crore in March 2025. Large corporate exposure above Rs. 100 crore was largely concentrated in better-rated names, with 99.1 percent rated A and above as of March 2026 for standard advances above Rs. 100 crore.

Asset quality drives earnings resilience

If FY26 had one defining operational achievement, it was the decline in stressed assets and the improved buffer built through provisions. Gross NPA fell to 1.43 percent in March 2026 from 3.20 percent in March 2025. Net NPA declined to 0.29 percent from 0.92 percent over the same period. In absolute terms, GNPA reduced to Rs. 1,430 crore in March 2026 from Rs. 2,800 crore in March 2025, while NNPA reduced to Rs. 288 crore from Rs. 791 crore.

Early delinquency indicators also improved. SMA 1 reduced to Rs. 427 crore, or 0.4 percent of advances, and SMA 2 dropped to Rs. 182 crore, or 0.2 percent of advances. Slippages in March 2026 were Rs. 147 crore, with slippage ratio at 0.15. The bank highlighted a full-year slippage ratio of 0.72 percent.

The quarter’s credit cost prints show why profitability held up even as margins tightened. Credit cost was 0.03 percent in Q4 FY26, compared with 0.26 percent in Q4 FY25. Provisions and contingencies for the quarter were Rs. 34 crore, down sharply from the prior year, helping offset weaker non-interest income.

Provision coverage strengthened across the cycle. PCR including write-offs rose to 94.10 percent in March 2026 from 85.03 percent in March 2025. PCR excluding write-offs improved to 79.87 percent from 71.77 percent. This matters because it gives the bank greater flexibility to pursue growth in higher-yield segments without allowing credit volatility to dominate the income statement.

There is also a structural message in how the bank frames its book transition. The presentation states that 88 percent of the overall loan book has been churned since October 2020. It also states that 77 percent of current GNPA is from the old book, with GNPA of old book at 8.85 percent and GNPA of new book at 0.38 percent. The implication is that incremental risk appears better controlled, and the tail risk is increasingly contained within a shrinking legacy pool.

Deposits, costs, and the operating engine

On the liabilities side, South Indian Bank continued to build a larger retail deposit base while keeping CASA steady. CASA ratio was 32.12 percent in Q4 FY26 versus 31.37 percent in Q4 FY25. CASA balances increased to Rs. 39,621 crore from Rs. 33,730 crore over the same period. Within deposits, savings balances rose to Rs. 32,475 crore and current accounts to Rs. 7,146 crore.

NRI deposits remained a meaningful franchise, reaching Rs. 35,371 crore at Q4 FY26 compared with Rs. 31,602 crore at Q4 FY25. Low-cost NRI deposits increased to Rs. 12,462 crore from Rs. 10,322 crore, while NRE term deposits stood at Rs. 21,264 crore.

The cost of funds stayed broadly stable through the year. Cost of funds was 4.77 in Q4 FY26 compared with 4.96 in Q4 FY25. Yield on funds was 7.42 in Q4 FY26 compared with 7.83 in Q4 FY25. Yield on advances was 8.43 percent in Q4 FY26 versus 9.02 percent in Q4 FY25. This compression is visible in NIM, which declined to 2.95 percent in Q4 FY26 from 3.21 percent in Q4 FY25.

What supports profitability in this context is operating discipline. Operating expenses reduced to Rs. 720 crore in Q4 FY26 from Rs. 757 crore in Q4 FY25. The bank also highlighted that it delivered positive operating leverage for the second consecutive year and continued active monitoring and optimization of cost structures.

Operational productivity metrics moved up. Business per employee rose to Rs. 22.7 crore in Q4 FY26 from Rs. 20.4 crore in Q4 FY25. Business per branch improved to Rs. 216 crore from Rs. 198 crore. The branch network remained stable at 948 branches, while digital transactions accounted for 98.5 percent of total transactions.

Cost-to-income ratio in Q4 FY26 stood at 55.3 percent, compared with 52.6 percent in Q4 FY25. The quarterly movement also reflects variations in income mix, especially non-interest income and treasury volatility.

Digital build-out and process redesign as strategic levers

South Indian Bank’s transformation story is not limited to asset quality cleanup. The bank is attempting to rewire how business is originated, processed, and serviced. The presentation positions digital and process design as central to improving branch productivity, reducing friction, and scaling retail and MSME growth.

On branch redesign, the bank described Branch 2.0 as a shift from transaction focus to community presence and customer engagement, and a move from evolutionary processes to consciously designed processes. The bank said it is centralizing and automating work to free up branch time. It also provided a process reengineering update: 3 processes automated, 14 eliminated, 10 centralized, 7 optimized, and 45 under review for upgradation.

On digital initiatives, the bank cited the re-engineering of the SIB Mirror plus app into a digital gateway, expansion of SIBerNet integrations with government entities like EPFO, ESIC, and Karnataka treasury, and a trade finance module on the corporate platform. It also highlighted end-to-end digitization of locker documentation and digitized stock statement submission.

Product and origination initiatives included SIB FINX as a digital savings product, SIB RED portal for products and services, and digital personal loan origination through a secure portal with OTP-based authentication and LOS integration. The bank also highlighted an in-house developed LOS to strengthen digital lending controls and processing speed.

The bank also disclosed that AI capabilities are now in production across the bank, powered by Zeni, its in-house open-source-based AI framework, complemented by vendor partnerships. Examples included automated day-book audit and a regulatory compliance chatbot. The list of in-production capabilities included an enterprise generative AI assistant, retrieval-augmented generation for internal knowledge search, agentic customer support for document retrieval, AI-assisted engineering, IT change governance, signature verification, and review and complaint intelligence.

This technology posture is paired with a stated roadmap of straight-through processing for credit journeys. The bank outlined multiple STP initiatives that are live, such as GST Power for MSME overdraft proposals up to Rs. 500 lakh, LAP Power, Power Drive for vehicle loans, Aawas Power for affordable housing loans, Micro Power for MUDRA and SIB UDAY proposals up to Rs. 10 lakhs, and Edu Power for overseas education finance. Additional live modules include gold loan digitalization with e-sign, auto renewal of KCC up to Rs. 5 crores, and AI ML based document generation for credit documentation.

Partnership-led distribution is another lever. The bank listed live co-lending partnerships including moneyview, Godrej Housing Finance, Muthoot Fincorp, Fedbank Financial Services Limited, axio, IIFL, Rupeek, and amazon pay. It also listed a debit card EMI program with Pine Labs, a co-lending and DA platform with Northern Arc, loan against mutual fund partnerships with smallcase and DhanLAP, and insurance premium financing with Finsall. On liabilities, it cited a fintech partnership with upswing to enable new-to-bank deposit account opening.

What investors should take away

South Indian Bank’s FY26 results show a bank that is increasingly being run for repeatable execution rather than one-off swings. The earnings quality is improving because the balance sheet is cleaner. The sharp fall in GNPA to 1.43 percent and NNPA to 0.29 percent, alongside PCR including write-offs of 94.10 percent, reduces downside risk and raises the visibility of future profitability.

At the same time, the operating picture is nuanced. Growth is healthy, but margins are under pressure, with NIM at 2.95 percent in Q4 FY26 versus 3.21 percent a year ago. Non-interest income can also be volatile, as seen in Q4 FY26 where non-interest income fell to Rs. 386 crore from Rs. 572 crore in Q4 FY25. This makes cost discipline, deposit franchise strength, and the ability to scale granular lending even more important.

The strategic direction is consistent across the presentation: shift the book toward MSME and retail, drive branch productivity through process redesign, and use digital systems and AI-led tools to improve speed and control. The bank’s disclosure that most of the current GNPA comes from the old book reinforces the credibility of the new underwriting and monitoring framework, even if investors will continue to watch how retail and MSME expansion behaves across cycles.

The quarter ends with a clear message. South Indian Bank is closing FY26 with its best-ever annual profit, stronger capital at 19.66 percent CRAR, and a sharper operating engine built on process and technology. The next phase will test whether the bank can sustain growth in higher-yield segments while protecting margins and keeping asset quality metrics near the current lows. For now, the numbers support the central claim: consolidation has been done with discipline, and the bank is building ahead with a more resilient core.
