Where does growth come from?
The bank is successfully pivoting to high-yield retail, with Home Loans growing at 55% and Auto Loans at 24% YoY, significantly outperforming the overall 9% gross advance growth. (5 accelerating across 5 signals)
“Retail segment continues to grow for us; it has grown YOY at 23%.”
Digital adoption is accelerating with branch productivity increasing by 60% following the rollout of platforms like GST Power and LAP Power. (3 accelerating, 2 new trend across 5 signals, 3 leading indicators)
“For working capital facilities to small businesses, we have something called GST Power. For LAP, we have something called LAP Power. These are all journeys in a fully digital mode”
CASA growth was muted at 3% YoY due to high interest rates and a large account exit, but management expects a reversal as interest rates drop. (5 steady across 5 signals)
“CASA balances grew by 15% year-on-year to Rs.37,640 crores”
The bank maintains a very high CRAR of 19.31%, providing significant headroom for the targeted 12-15% loan growth in the coming year. (4 steady, 1 accelerating across 5 signals, 2 leading indicators)
“Gold (Incl Agri) ... Dec'25 Rs. 21,303 Cr ... 26%”
The CRAR remains robust at 17.70%, well above regulatory requirements, though it has slightly declined from 18.04% a year ago as capital is deployed to fund the 9% loan book expansion. (1 steady across 1 signal)
“in a 12-month period, we should end the 12 months at about 1.15% to 1.2% or thereabouts.”

What could break the thesis?
NIM remains under pressure as the bank passed on 100 bps of repo rate cuts to borrowers immediately while deposit costs have not moved in sync. Management expects bottoming in Q2. (4 intensifying, 1 easing, 1 high-severity)
“Net Interest Margin Q3FY26 2.86% Q3FY25 3.19%”
Profitability metrics remain under pressure; RoA is stable at 1.01% (vs 1.00% YoY) but RoE has slipped to 12.41% from 12.90% YoY and 13.74% in the previous quarter. (2 intensifying, 2 easing, 1 stable)
“Return on Assets 1.07% (Q3FY26) 1.12% (Q3FY25); Return on Equity 13.49% (Q3FY26) 13.93% (Q3FY25)”
The bank's 'CASA' ratio—the proportion of low-cost savings and current accounts—is relatively stagnant, which limits its ability to lower its overall cost of funds compared to larger competitors. [MARGIN_COST]
“CASA % 31.84% (Q3FY26) 31.15% (Q3FY25)”
CD ratio appears to have improved to approximately 79% (Advances 89,198cr / Deposits 112,922cr), providing more liquidity headroom. (1 easing, 1 stable)
“With respect to CD ratio, we are at approximately 82% or so in the last quarter. We think that there is still some headroom available there. We can get to 85%, 86%.”
Cost of deposits continues to rise, reaching 5.58% in Q4FY25 compared to 5.33% in Q4FY24, indicating intensifying competition for funds. (1 intensifying, 4 easing)
