Stronger Deposit Growth Than Loans
AU Small Finance Bank has reported year-on-year deposit growth of 22.8%, which is higher than its gross loan portfolio expansion of 21.3%. This trend is different from the broader Indian banking sector, where, as of mid-March, credit grew 13.8% year-on-year, significantly outpacing deposit growth at 10.8%. AU Bank's own gross advances, excluding securitized assets, rose even faster at 25.1%. As of April 2, 2026, the bank's stock traded at ₹868.25, having gained about 54% in the past year. This positive difference between deposit and loan growth suggests a strong liquidity position for the bank.
Falling CASA Ratio Signals Higher Costs
Despite healthy overall deposit growth, AU Small Finance Bank's Current and Savings Account (CASA) ratio slightly decreased to 28.4% from 29.2% a year ago. This happened because growth in fixed deposits outpaced the growth in CASA accounts, indicating a move towards more expensive funding sources. This situation is also seen across the Indian banking industry, where competition for deposits is increasing, leading to higher term deposit rates and making it harder for banks to gather low-cost funds. This dynamic pressures Net Interest Margins (NIMs), which have generally declined across the sector due to rising deposit costs. While AU Bank has historically maintained strong NIMs between 5%–6%, its ability to keep these levels up will be important to watch. The majority of the bank's deposits, about 79% of its liabilities, remain stable.
Valuation and Analyst Views
AU Small Finance Bank has a market capitalization of around ₹65,000 crore. Its trailing twelve-month Price-to-Earnings (P/E) ratio is approximately 28 times. The stock has seen significant gains, reaching a 52-week high of ₹1,039.20 and a low of ₹513.50. Analyst sentiment is mixed, with a general 'Neutral' rating based on reports from over two dozen analysts. The average 12-month price target is around ₹1,035, suggesting a potential increase of roughly 13-19% from current prices. While some analysts recommend buying the stock, many suggest holding or selling, reflecting differing opinions on the bank's growth potential and ability to maintain profit margins.
Margin Squeeze Risk
The ongoing drop in the CASA ratio, even with overall strong deposit growth, poses a potential risk to AU Small Finance Bank's profits. As the industry faces high credit-deposit ratios and a shift away from low-cost savings accounts towards market-linked instruments, banks like AU SFB face greater challenges in securing stable funding. Relying more on fixed deposits helps meet loan demand but directly increases the cost of funds. This could reduce profit margins if AU Bank cannot increase loan interest rates to match its higher borrowing costs, especially in a competitive market for both deposits and loans. Smaller Small Finance Banks (SFBs) often have fewer funding options compared to larger universal banks, making them more sensitive to changes in depositor preferences and interest rates. Reports suggest that while AU SFB is considered more efficient and liquid than peers like Equitas Small Finance Bank, its CASA ratio is lower than that of many mid-sized private sector banks.
Growth Outlook
AU Small Finance Bank is expected to continue its growth. Loan growth is projected at around 21% for FY26, with a compound annual growth rate (CAGR) of approximately 24% expected from FY26 to FY28. Deposit mobilization is also anticipated to remain healthy, supported by the bank's improving brand and its potential move towards becoming a universal bank. Analysts predict that mid-sized banks, including AU Small Finance Bank, might see modest profit margin growth due to falling credit costs. However, the bank's success will depend on its ability to manage increasing funding costs and maintain good asset quality in an evolving and competitive banking environment.
