CSB Bank Ltd Q4 FY2025 Concall Summary

Key Takeaways

• Profit surges on fee income, NIM dips: Net profit rose 26% YoY to INR 190 crores in Q4, driven by a 94% quarterly jump in other income, while NIM compressed to 3.75% as the bank held excess liquidity and paid higher hedging costs.
• The bank is rebuilding its tech core from scratch: A full-scale CBS migration to Oracle and surround-system overhaul is underway, with management calling it "building the bank afresh"; the build phase ends in 3-6 months, after which the customer franchise and scaling journey begins.
• Asset growth is not the problem, funding is: Net advances grew 29% YoY, roughly double the industry pace, but management flagged that liability generation is now the binding constraint on growth, with a retail liability push still 12-18 months away.
• Unsecured stress is contained and shrinking: The unsecured book is just 3.3% of assets and degrowing; management took 50% upfront provisions on slippages and expects the drag to become negligible within two quarters.
• What to watch next quarter: Whether NIM has truly bottomed as guided, the pace of deposit repricing as rates fall, and any early signs of the tech migration's impact on business momentum.

Profitability & Margins

• NIM compressed on multiple fronts: Excess liquidity held for the first two months of the quarter depressed yields on idle cash, while hedging costs on FCY borrowings spiked temporarily due to global uncertainty and a strong dollar index. The bank also pulled back from high-yielding businesses like personal loans, Agri and MFI, bringing overall portfolio yield down.
• The trade-off was deliberate and neutral at the ROA level: What was lost on the NIM side was gained on other income via treasury trading, which management called "kind of one-off" but noted that significant MTM gains were left unbooked, leaving room for further fee income in FY26.
• NIM is guided to have bottomed: Management stated NIM will not come down further and should play in the 3.75% to 4.14% range for the full year FY26, supported by falling G-Sec yields and the fact that 60% of the loan book is fixed-rate and less yield-sensitive.
• Cost-to-income improved sequentially to 57.92% in Q4, but the FY25 figure of 62.82% remains elevated. Management guided ~65% through FY27, then a sharp drop to 50% between FY27 and FY30 as the tech-enabled franchise scales.
• ROA and ROE targets are modest but steady: ROA is guided closer to 1.5% for the next 1-2 quarters, with a minimum 1.5% floor and ROE between 15% and 18% over the medium term.

Mondal: "I think we are hitting our bottom on the NIM. I don't think coming down further anymore."

The Tech Transformation Bet

• The entire tech stack is being replaced: The bank is migrating its core banking system to Oracle alongside new digital platforms (OBDX), a new cash management system, loan origination systems, and supply chain platforms. The datacentre migration is already complete. Management described it as effectively building the bank afresh.
• The build phase ends in 3-6 months: Once the core system migration is done, the bank can begin targeting new segments, launching retail assets, and scaling transaction banking and wholesale. The customer acquisition strategy starts six months from now.
• This is a first-of-its-kind migration at this scale, per management, and they cautioned that the transition itself carries execution risk: "we have to see how this transition goes."
• Branches are being placed now for the post-migration world: The bank added 56 branches in FY25 and will maintain a pace of 50-100 per year, with significant expansion from FY27. These branches are positioned in North, West and South India and are expected to get leveraged more once the tech transformation is complete.
• Other opex rose 35% primarily due to technology-related expenses, both capex and opex, as the migration nears execution. Management said costs are already baked in and no major opex increase is expected next year versus FY25.

Mondal: "Effectively, we are building the bank afresh in the next 6 months. The way the customer sees the bank and the way that we service the customer, the way we build products, the way we create franchise on the transaction banking, wholesale, retail, SME everywhere- is completely going to change."

Asset Quality & the Unsecured Run-Off

• GNPA improved mildly to 1.57%, with NNPA at 0.52% and a provision coverage ratio that jumped from ~60% to 67.19% without considering written-off accounts. The bank holds an INR 185 crore provisioning buffer over regulatory requirements.
• Slippages were 1.19% in Q4, down from 2.16% a year ago, but the composition matters: part came from planned migration provisions, part from unsecured slippages where 50% was provided upfront, and part from prudent provisioning on security deterioration in a few legacy accounts.
• The unsecured book is small and shrinking: At 3.3% of the overall book, it has been in degrowth mode for a year. Management expects it to become negligible within two quarters, with maximum six more months of residual flow-through. Credit cards are the only component that may linger.
• Credit cost is guided below 30 bps for FY26, and management expressed confidence they can do better than FY25. One analyst's math suggests credit cost could go below 29 bps.
• A legacy corporate account remains stuck in legal proceedings: The account that slipped about a year ago is in a legal tangle, but the bank holds secured assets and expects eventual recovery. No specific provision amount was disclosed.

Growth & the Liability Constraint

• Asset growth of 29% YoY was broad-based: Gold loans grew 35%, retail ex-gold 24%, SME 33%, and wholesale 22% despite a 89% degrowth in the DA portfolio. Corporate loans standalone grew 44%.
• The binding constraint is now liability generation: Management was explicit that growth is not a problem on the asset side; the limit is how much deposit funding the bank can raise. This forces disciplined asset selection, focusing on where risk-adjusted returns are highest.
• Deposit growth was robust at 24% YoY versus ~10% for the industry, but CASA grew only 10% and the CASA ratio sits at 24.19%. The bank is using bulk deposits and FCY borrowings as bridge funding until the retail liability journey starts in 12-18 months.
• Deposit repricing is coming: Management made a strategic call not to lock into long-term deposits as rates are falling, expecting repricing to begin in another quarter or two. Combined with a fixed-rate-heavy loan book, this should support NIM as rates decline.
• Growth of 20-25% is anticipated for now, but the bank will choose and pick assets within its 8-12% yield range, prioritizing higher risk-adjusted returns.

Mondal: "Our constraint will be how much liability we can generate. That is what will constrain our growth. Because of that, we will be in a good place to say which is the franchise growth we want to have and from where we are getting higher risk-adjusted return, that's where we'll do business."

Fee Income & the Business Mix Shift

• Other income surged 94% QoQ and 66% for the full year, now constituting 21% of total income. The five major drivers were gold loan processing fees, wholesale banking, treasury income, PSLC benefits, and insurance.
• Treasury gains were deliberately under-booked: Management left significant MTM gains on the table, expecting G-Sec yields to continue falling. They see a "significant opportunity" to book more other income in FY26 and do not expect fee income to come down; if anything, it will grow "quite handsomely."
• Core fees should accelerate in H2 FY26: The launch of retail assets, the ramp-up of corporate banking, and the activation of transaction banking once CMS and supply chain systems go live will all contribute. Management said core fees "will only improve over a period of time."
• The business model deliberately trades NIM for fees: On the wholesale side, the bank generally does not lend above 9.5-10%, earning ROA through fees rather than yield. This philosophy extends across the franchise: lower-yielding, best risk-adjusted, long-term sustainable businesses with better cross-sell.

Gold Loan Portfolio & Regulatory Watch

• Gold loans are 44% of the asset book and non-elastic to rate cycles: Yield will remain in the 11.5-12% range regardless of where policy rates go, providing a stable high-yield anchor as the rest of the book reprices downward.
• Lower LTV is a feature, not a bug: As gold prices rise, the bank is not comfortable taking high LTV risk and lets LTV decline naturally. Management runs detailed sensitivity analysis for every 5-10% drop in gold price.
• Account numbers declined because the bank stopped sourcing loans below INR 2 lakh, where guidelines do not permit collateral security. This caused average ticket sizes to improve.
• The RBI's draft circular on gold loans is still under discussion: Management called it too early to comment, noting that representations are being made through IBA and other bodies. The bank has started preparatory work and will incorporate changes into the new system arriving next quarter.
