AU Small Finance Bank Q1 FY26 results: can deposit-led momentum sustain as NIMs soften in a rate-cut cycle?

AU Small Finance Bank Limited (NSE: AUBANK, BSE: 540611) has reported a profit after tax of ₹581 crore for the quarter ended June 30, 2025, marking a 16% year-on-year (YoY) growth from ₹503 crore in Q1 FY25. Net total income surged 18% YoY to ₹2,855 crore, while pre-provision operating profit rose 38% YoY to ₹1,312 crore, reflecting operational strength despite a challenging macroeconomic environment. The small finance bank’s annualised return on assets (RoA) stood at 1.5% and return on equity (RoE) at 13.3%, broadly in line with previous quarters.

Deposits grew 31% YoY to ₹1,27,696 crore, with current and savings account (CASA) deposits expanding 16% to ₹37,241 crore, representing a CASA ratio of 29.2%. The gross loan portfolio stood at ₹1,17,624 crore, up 18% YoY, supported by a 22% growth in secured lending segments.

The stock of AU Small Finance Bank closed at ₹790.30 on July 18, 2025, down 0.83% from the previous session. Traded volumes stood at 15.02 lakh shares with a VWAP of ₹793.19. Institutional investors maintained a cautiously positive outlook, citing strong capital adequacy at 20% and Tier-I capital at 18.2%, though shrinking net interest margins (NIMs), which fell 38 basis points sequentially to 5.4%, remain a concern.

How is AU Small Finance Bank balancing deposit-led growth with margin pressures in Q1 FY26?

AU Small Finance Bank’s deposit franchise continues to expand at a robust pace, with stable deposits—CASA, retail term deposits, and non-callable bulk deposits—accounting for 79% of total deposits. Current deposits grew 34% YoY to ₹6,348 crore, and savings deposits rose 13% YoY to ₹30,983 crore. The bank has actively re-priced its liabilities, reducing peak savings rates by 50 basis points to 6.75% and term deposit rates by 90 basis points to 7.1% since March 2025.

The cost of funds (CoF) declined modestly by six basis points to 7.08% in Q1 FY26, while incremental CoF fell by 62 basis points from Q4 FY25, indicating early benefits from the Reserve Bank of India’s cumulative 100 basis points policy rate cuts. However, the full benefit of lower funding costs is expected to flow through gradually, as competitive deposit pricing continues to limit significant CoF compression.

Institutional investors view the deposit-led growth as a key differentiator in a softening rate environment. Some analysts indirectly noted that the bank’s proactive liability management positions it well to capture future loan demand once broader economic momentum strengthens, although near-term NIM recovery is likely to be gradual.

What does the loan book composition reveal about AU Small Finance Bank’s risk strategy as unsecured growth slows?

The loan book composition shows a deliberate shift toward secured retail and commercial lending, which grew 22% YoY. In contrast, unsecured portfolios—primarily microfinance and credit cards—declined 23% YoY, reflecting a strategic recalibration amid cyclical slowdown in microfinance and controlled credit card growth.

Gross non-performing assets (GNPA) rose to 2.47% in Q1 FY26 from 2.28% in Q4 FY25, and net NPA increased to 0.88%. Provision coverage ratio (PCR), including technical write-offs, stood at 83%, and additional floating and contingency provisions totaled ₹58 crore, providing a cushion against potential asset quality deterioration. Net credit cost remained contained at 0.34% of average total assets.

Institutional investors have interpreted this conservative stance positively, highlighting the bank’s average liquidity coverage ratio (LCR) of 123%, up from 116% in Q4 FY25. However, some remain watchful of the unsecured loan book’s cyclical pressures and their potential impact on earnings in subsequent quarters.

Can AU Small Finance Bank sustain profitability and investor confidence amid a shifting interest rate cycle?

The bank’s operational efficiency improved significantly, with the cost-to-income ratio falling to 54% in Q1 FY26 from 60.8% a year ago. Other income grew 59% YoY to ₹811 crore, primarily driven by treasury gains, while net interest income rose 6% YoY to ₹2,045 crore. Earnings per share increased 15% YoY to ₹7.8, and book value per share rose 14% YoY to ₹239.

AU Small Finance Bank has reinforced its long-term strategic positioning with new initiatives, including a climate risk advisory partnership with International Finance Corporation and an insurance penetration collaboration with Life Insurance Corporation of India. Lifestyle and premium banking initiatives, such as AU ivy and AU Eternity concierge services, along with airport transfer tie-ups for NRI customers, underline its efforts to deepen customer engagement across segments.

Institutional investors have emphasized that the bank’s AA+/Stable fixed deposit rating and robust capital buffers provide confidence in its ability to navigate near-term NIM pressures. However, they also expect a careful balance between growth and credit quality, especially as private sector competitors increase pricing aggression in retail segments.

What are the key factors that could influence AU Small Finance Bank’s growth and investor confidence in the remaining quarters of FY26?

Founder and CEO Sanjay Agarwal stated that AU Small Finance Bank Limited remains cautiously optimistic heading into the next few quarters, pointing to supportive policy conditions, easing inflationary pressures, and surplus liquidity as clear tailwinds for credit growth. He noted that the Reserve Bank of India’s cumulative 100-basis-point rate cuts, combined with forthcoming cash reserve ratio adjustments, are expected to further reduce funding costs and strengthen the banking system’s ability to mobilize deposits.

However, Agarwal acknowledged that domestic demand recovery remains uneven across sectors, with discretionary spending still muted in rural markets and credit demand in microfinance segments showing cyclical weakness. Global uncertainties—particularly in commodity prices and trade flows—pose additional risks, making the bank’s conservative credit stance critical in navigating potential volatility.

Institutional investors indirectly expressed that sustained deposit accretion, stable asset quality, and continued traction in secured lending portfolios will be key triggers for maintaining investor confidence. They have also emphasized that AU Small Finance Bank’s ability to defend its net interest margin, even as competition from private banks intensifies, will serve as a primary driver for earnings momentum in FY26.

The bank’s stock, which is trading close to its 52-week high of ₹841, reflects growing investor confidence in its long-term franchise value. Yet, market watchers believe that any significant re-rating will depend on visible NIM stabilization, strong growth in retail secured lending, and consistent improvement in cost-to-income ratios. With capital adequacy at a healthy 20% and a robust Tier-I ratio of 18.2%, AU Small Finance Bank appears well-capitalized to leverage improving macroeconomic conditions while preserving credit discipline.
