Q4 FY26 Results: Strong Growth and Key Metrics

Recent Q4 FY26 results from Bank of India (BOI), Punjab National Bank (PNB), and Central Bank of India (CBI) show strong performance in the Indian banking sector. These banks reported solid loan and deposit growth, especially in the profitable retail and SME segments, demonstrating resilience. However, attractive valuations and good results also highlight sector trends and challenges that require a closer look beyond simple price-to-book ratios.

In the March 2026 quarter, Bank of India's loans grew by 17.1%, PNB's by 13.7%, and Central Bank of India's by an impressive 19.1%. This growth surpassed the wider market's credit expansion. Bank of India's deposits rose 13.6%, PNB's by 9.3%, and CBI's by 13.3%, providing a solid funding base. Net Interest Margins (NIMs) faced sector-wide pressure. BOI held its NIM around 2.6% and CBI at 3.25%, while PNB saw a dip. For comparison, SBI's advances grew 17.2% with a NIM of 2.93%. As of May 18, 2026, BOI traded around ₹138.22, PNB at ₹99.80, CBI at ₹33.77, and SBI at ₹939.40. Reported net non-performing assets (NPAs) remained low: BOI at 0.56%, PNB at 0.29%, and CBI at 0.49%, indicating stable asset quality. BOI and CBI also reduced provisions.

Valuation Discounts vs. SBI and Market Performance

Public sector banks like BOI, PNB, and CBI continue to trade at significant discounts to State Bank of India. Their price-to-book (P/B) ratios stand around 0.7x-0.8x, while SBI's is between 1.45x-1.6x. This valuation gap has attracted investor attention, especially as the Nifty PSU Bank index has significantly outperformed private bank indices over one and three years, with returns of about 25% and 109% respectively. Public sector banks are now showing loan growth matching or exceeding private banks, a trend not seen in over a decade. This aggressive growth strategy, particularly in corporate and SME lending, has prompted private banks like ICICI Bank (P/B ~3.5) to acknowledge increased competition and pricing pressures from PSUs. This suggests PSUs might be lowering margins to gain market share. Across the sector, net interest margins (NIMs) are under pressure due to the lag in repricing deposits against lending rates. This could impact profitability for all banks. Meanwhile, foreign institutional investor (FII) ownership has increased in PSU banks, while decreasing in private counterparts, signaling a shift towards perceived value in the state-owned segment.

Key Risks and Challenges Ahead

Despite attractive valuations and recent performance, several risks face the PSU banking sector. The aggressive loan growth strategy, while boosting market share, could pressure Net Interest Margins (NIMs). Private banks note that PSUs are using aggressive pricing, which may hurt profitability if not carefully managed. Historical volatility in P/E ratios for PNB, CBI, and BOI shows that market sentiment can change quickly if earnings falter. Central Bank of India's net profit fell nearly 30% in Q4 FY26 due to a one-time tax charge, highlighting potential for unexpected financial hits. While asset quality has improved, the economic outlook for FY27, projected at 6%-6.5% growth, faces risks from global volatilities, such as energy price shocks due to ongoing geopolitical conflicts. Furthermore, while PSU banks might be more resilient to Expected Credit Loss (ECL) regulations due to less available contingent buffers compared to larger private banks like SBI, this could present future challenges. Analyst reports have also flagged management quality in some smaller PSUs as 'Poor,' raising concerns about long-term strategy and risk management.

Outlook for FY27

Analysts will closely watch loan and deposit growth, NIM trends, and asset quality. For FY27, PNB has guided for loan growth of 12-13% and NIMs between 2.6% and 2.7%. The continued outperformance of PSU banks will depend on their ability to balance aggressive market share growth with margin protection and prudent risk management. While current valuations offer a compelling entry point compared to private sector peers, increasing competitive intensity and macroeconomic uncertainties present significant challenges for further valuation gains.
