CSB Bank Q1FY26: Deposits up 20% YoY, loans 32%

What CSB Bank reported and why it matters

CSB Bank’s latest business and quarterly updates show a sharp rise in both deposits and credit, with gold loans emerging as a key driver. Across different reference dates mentioned in the updates, the bank reported deposit growth in the 20% to 25% range year-on-year, while advances grew closer to 29% to 32% year-on-year. The pace of credit growth stands out against the bank’s own longer-term growth rates cited in the disclosures. Investors also tracked the updates because they included a brief market reaction and a management commentary around a technology migration completed during the quarter.

Deposits: multiple reference points show 20%+ growth

For the quarter ended June 30, 2025 (Q1 FY26), CSB Bank reported total deposits of ₹35,935 crore, up 20% YoY from ₹29,920 crore as on June 30, 2024. In a separate provisional business update for Q1 FY26, total deposits were reported at ₹35,990 crore, up 20% YoY, but down 2.4% QoQ. The provisional note attributed the sequential decline to a 1.5% QoQ de-growth in term deposits and a 5% QoQ decline in CASA deposits.

The bank also disclosed that total deposits were ₹36,861.49 crore as on March 31, 2025, up 24.03% YoY. Another data point stated total deposits at ₹40,460 crore as on December 31, 2025, up 21% YoY. Taken together, the reported figures indicate that deposit growth remained strong on a year-on-year basis, even when quarter-on-quarter movement was softer in the provisional Q1 snapshot.

CASA and term deposits: mix signals from reported numbers

CSB Bank’s reported CASA ratio stood at 23% as of June 30, 2025, and 24% as of March 31, 2025. In the provisional Q1 FY26 update, CASA deposits were reported at ₹8,465 crore (down 5% QoQ), while term deposits were ₹27,525 crore (down 1.5% QoQ).

For September 30, 2025, the bank reported total deposits of ₹39,651 crore, up 25% YoY and 10% QoQ. Within this, CASA aggregated to ₹8,394 crore (up 9% YoY) and term deposits were ₹31,257 crore (up 29% YoY). The mix across periods suggests that term deposits formed the bulk of incremental deposits in that snapshot, while CASA growth was positive year-on-year but showed volatility sequentially in the provisional Q1 update.

Advances: credit expansion running ahead of longer-term averages

On the lending side, CSB Bank reported advances growth that outpaced its stated historical trajectory. One update stated the bank delivered a 29.47% YoY increase in advances, above its five-year advances CAGR of 16.89%, with three-year advance growth at 25.83%.

In the provisional business performance for Q1 FY26, gross advances grew 32% YoY (and 4% QoQ) to ₹33,142 crore. In another disclosure on September 30, 2025, gross advances were reported at ₹34,730 crore, up 29% YoY and up 5% sequentially versus ₹32,944 crore as on June 30, 2025.

Gold loans remain a key engine

Gold loans were repeatedly highlighted as a major contributor to growth. In the provisional Q1 FY26 update, gold loans rose 36% YoY (and 5.9% QoQ) to ₹14,928 crore. In management commentary, the MD and CEO noted deposits grew by 22% and advances by 26%, with gold loans growing 36% YoY as an important contributor. Another summary line also referenced gold loans growth at 46% YoY alongside deposits up 21% YoY and gross advances up 29% YoY.

Profitability and income: Q1 FY26 operating performance

For Q1 FY26, CSB Bank reported net profit of ₹119 crore, up 5%, alongside net operating income of ₹624 crore, up 17% (both compared with Q1 FY25). Net Interest Income (NII) was ₹379 crore for Q1 FY26, up 5% YoY from ₹362 crore for Q1 FY25. Non-interest income rose to ₹245 crore, up 42% YoY from ₹172 crore.

Separately, another data point in the updates stated Profit after Tax of ₹113.32 crore in Q1 FY25 versus ₹132.22 crore in Q1 FY24, alongside an “accelerated provisioning policy” and reported Return on Assets (RoA) of 1.27% and NIM of 4.36% for that quarter.

Asset quality snapshot: GNPA and NNPA levels cited

An asset quality snapshot in the provided text cited gross NPA at 1.84% and net NPA at 66 basis points. The update did not provide a comparable prior-period figure in the same excerpt, but the numbers were presented as the bank’s overall GNPA and NNPA readings.

Technology migration: management flags operational milestone

The Board approved financial results for the quarter ended June 30, 2025 in a meeting held on August 13, 2025, following a limited review by the statutory auditors. The MD and CEO described Q1 FY26 as “special” due to a core banking system migration and the launch of over 50 supporting systems. He also noted that despite transition challenges and higher costs, the bank delivered growth in deposits, advances, and fee income.

Market reaction and stated impact

One market update in the text noted the stock advanced 1.40% to ₹384.95 after the bank reported a rise in gross advances and deposits (as per the cited disclosure). Another section explicitly classified the update’s impact as Neutral.

Key numbers table (as reported across updates)

Analysis: what stands out from the disclosures

The most consistent theme in the reported updates is that CSB Bank’s balance sheet grew faster than its longer-term averages cited in the text, particularly on advances. Gold loans repeatedly show up as the sharpest-growing component, with YoY growth figures around the mid-30% range in the Q1 FY26 update. On deposits, the year-on-year momentum appears intact across dates, but the provisional Q1 data also pointed to quarter-on-quarter softness in both term deposits and CASA.

The quarterly numbers also show a meaningful increase in non-interest income, while NII growth was more modest. Alongside this, management placed emphasis on the core banking migration and the rollout of supporting systems, positioning the quarter as operationally important even as it came with higher costs.

Conclusion

CSB Bank’s latest updates point to strong year-on-year balance sheet expansion, led by gold loans, with deposits and advances showing consistent double-digit growth across reported reference dates. The next markers to watch, based on the disclosures, are how deposit mix trends after the provisional QoQ dip and how the bank sustains growth following its core banking migration and systems rollout.
