Tamilnad Mercantile Bank Q4 FY2026: Growth Returns, Asset Quality Tightens, and MSME Becomes the Next Growth Engine

Tamilnad Mercantile Bank (TMB) closed Q4 FY2026 with a clear change in tone versus the prior few quarters. The bank’s investor presentation framed FY26 as a transformation year, and the numbers in Q4 support that narrative. Total business reached 1,15,091 crore, up 17.37% year on year. Deposits rose to 61,712 crore, up 14.94%, while advances increased to 53,379 crore, up 20.32% year on year.

Profitability also moved up in step with balance sheet growth. Net interest income for Q4 FY2026 was 704.45 crore, up 24.04% year on year. Operating profit rose to 522.31 crore, up 29.29%, and net profit was 373.65 crore, up 28.01%.

A key nuance in the quarter was expense recognition. Management stated that the bank front-loaded 49.80 crore of performance-based incentive provision in Q4 FY2026, which is normally booked in the subsequent year. The bank also provided normalized commentary: excluding this one item, cost-to-income would have been 39.54% for Q4.

Deposits: CASA rebound becomes visible in reported mix

TMB’s deposit story in Q4 FY2026 is not just about growth. It is also about mix, which the management highlighted as a turnaround marker. CASA grew to 17,365 crore, up 22.35% year on year. CASA share improved to 28.14%, up 170 basis points year on year.

Within CASA, current accounts grew 25.62% year on year to 5,084 crore, and savings balances grew 21.04% year on year to 12,281 crore. Term deposits grew 12.28% year on year to 44,347 crore.

Management attributed CASA and deposit momentum to initiatives like the Transaction Banking Group (TBG), the Elite Service Group (ESG), and the introduction of liability relationship managers.

Advances: growth is strong, with gold loans still the centre of gravity

Advances growth remained the strongest part of the balance sheet narrative. Gross advances increased to 53,379 crore, up 20.32% year on year. The bank also noted that advances growth would be 22.57% if it included an IBPC sale of 1,000 crore in Q4.

The growth mix was tilted toward RAM, with RAM advances at 50,528 crore, up 22.35% year on year, and RAM share rising to 94.66% of gross advances.

The fastest growing sub-segment was retail at 62.33% year on year to 14,912 crore. Agriculture advances grew 8.03% to 20,084 crore. MSME advances grew 14.88% to 15,532 crore.

The bank also disclosed a portfolio mix shift between FY2025 and FY2026. Retail increased from 20.71% to 27.94% of advances, while agriculture reduced from 41.90% to 37.63%.

Financial summary (key disclosed metrics)

Notes: All figures are from the investor presentation and concall commentary. Advances growth excludes an IBPC sale of 1,000 crore unless otherwise stated.

Asset quality: low GNPA, low SMA, and high provision coverage

TMB’s asset quality remains a defining pillar of the quarter. As of Q4 FY2026, gross NPA reduced to 388.21 crore and GNPA ratio improved to 0.73%. Net NPA stood at 97.41 crore with NNPA at 0.18%.

The bank reported PCR (without technical write-off) at 74.89% and PCR (with technical write-off) at 96.14%. It also disclosed that average collateral coverage for NPAs was 127.52%, and stated this creates potential for provision write-back when resolutions occur.

Early stress indicators also improved. SMA (0,1,2) stood at 1.29% in Q4, down 126 basis points year on year. Stressed assets ratio, which includes standard restructured advances and gross NPAs, reduced to 1.14%.

In segment-wise NPA disclosure, retail and agriculture NPAs were very low at 0.13% and 0.16% respectively. MSME GNPA stood at 0.88%. The “Others” segment remained the stress pocket at 6.95% GNPA and lower collateral coverage (88.13%) than the overall average.

Gold loan portfolio: scale, buffers, and active risk monitoring

Gold loans remain central to TMB’s advances profile. The gold loan portfolio reached 24,790 crore as of 31.03.2026. The bank stated gold loan share at 46.44%.

The disclosure included both operational and risk metrics: portfolio LTV at 53.25%, portfolio yield at 10.11%, and net weight of 34.19 tons (gross weight 37.38 tons). The bank shared a sensitivity table showing that even after a 25% gold price drop, the portion of portfolio above market price was just 0.01%.

Management said the bank tracks gold prices continuously and is setting up asset resolution branches to manage LTV, margin calls, and auctions if needed.

At the other end of the risk spectrum, unsecured exposure was stated to be 0.10% of gross advances in Q4.

Strategy and execution: expansion, digital shift, and modernization

Branch expansion was a visible execution lever in FY2026. The bank opened 44 branches during the year, taking total branches to 622 as of 31.03.2026. Out of these, 15 new branches were in non-Tamil Nadu states. Management acknowledged it missed its earlier internal target of 50 branches in FY2026 and stated that 7 branches slipped beyond 31.03.2026.

In the earnings call, management guided to open 60 branches in FY2027.

Digital adoption continues to reshape operating capacity. The bank reported digital transaction count of 74.28 crore in FY2026 versus branch transaction count of 2.41 crore, taking digital share to 96.85%. Management also highlighted that branch counter transactions reduced despite an increase in branch count.

On modernization, the bank listed completed initiatives like Oracle Fusion implementation (HCM, CX and VMS), workflow automation, and an AI call centre. In progress items included automated reconciliation for digital transactions, treasury software upgrade, LOS and LMS (Phase 1 completed), mobile banking and UPI enhancements, an internet banking upgrade to a digital engagement hub, and a co-lending platform.

FY2027 guidance and regulatory watchpoints

TMB’s management offered explicit directional guidance in the earnings call. It stated a target to grow deposits in FY2027 at least 1% higher than FY2026, indicating about 16% deposit growth. It also stated it intends to defend about 20% advances growth in FY2027.

On margins, management said sustaining Q4 NIM may be difficult, but it expects to defend NIM in the 3.9% to 4.0% range.

The bank also discussed the transition to Expected Credit Loss (ECL) norms from 01.04.2027. As of 31.03.2026, it estimated a one-time additional provision impact of 279 crore, with CRAR impact up to 93 basis points if taken immediately. It said 250 crore of contingency provision held is sufficient to cover the impact.

Takeaways

TMB’s Q4 FY2026 is best understood as a convergence of three themes: balance sheet growth returning strongly, asset quality staying tight, and operational investments supporting scalability. The key question for FY2027, as management itself flagged, is the sustainability of growth drivers beyond gold loans. The bank is positioning MSME as the next major lever, supported by credit infrastructure like CMCs and loan systems, while simultaneously scaling distribution through branch additions and digital adoption.
