NIM Recovery Forecast

Analyst Deven Choksey projects HDFC Bank's Net Interest Margin (NIM) to climb from 3.38% to around 3.55% by the fourth quarter of fiscal year 2028. This recovery hinges on reducing the Cost of Funds (CoF) from approximately 4.99% to 4.60%. Alongside this margin expansion, operational efficiencies are expected to shrink the Cost-to-Income ratio from 39.9% to 39% by FY28E, significantly boosting Pre-Provision Operating Profit (PPOP) growth. However, HDFC Bank's current market valuation, trading at about 1.8 times its FY28E Average Book Value (ABV) for core operations, is considerably lower than its historical averages, suggesting investor caution despite steady Return on Assets (RoA) and Return on Equity (RoE).

Efficiency Measures Target Lower Costs

HDFC Bank aims to lower its Cost-to-Income ratio to around 39% by FY28E, by maximizing its large branch network and technology investments. This focus on efficiency is critical, as rising operating expenses have been a concern for Indian banks, pushing the system's average Cost-to-Income ratio to 57.08% in FY24. Achieving its target could help HDFC Bank accelerate Pre-Provision Operating Profit (PPOP) growth to roughly 20% by FY28E, faster than revenue growth. While large banks like SBI and HDFC Bank often have lower cost-to-income ratios than the system average, all banks face pressure to optimize operations.

Why the Discount Persists

HDFC Bank's market capitalization is around ₹12.4 lakh crore (~$150 billion) as of April 2026. Despite anticipated NIM recovery and efficiency gains, the stock's Price-to-Earnings (P/E) ratio remains in the 15.77x to 16.6x range. This represents a significant discount compared to its own historical valuations and the broader market. This gap is notable when compared to peers. While HDFC Bank aims for a 3.55% NIM, ICICI Bank is projected to achieve around 4.1% in FY26, and State Bank of India (SBI) reported 2.86% in Q3 FY25, showing varied NIM trends. The current discount might stem from market concerns about the pace of recovery or competitive challenges. Kotak Institutional Equities suggests that large private banks like HDFC Bank, ICICI Bank, and Axis Bank are now attractively priced after a re-evaluation, but they note that a sustained recovery in growth and return metrics has yet to fully materialize, implying near-term headwinds might justify the current discount.

Potential Headwinds and Risks

The persistent discount to its historical valuations prompts a closer examination of potential headwinds for HDFC Bank. The Indian banking sector faces increasing competition for deposits, driving up funding costs and squeezing margins for all lenders. Although HDFC Bank has a stronger CASA ratio (34.1% of total deposits) than the system average (37.9% as of Dec 2025), tighter liquidity and slower deposit growth relative to credit expansion present risks. Additionally, Reserve Bank of India (RBI) rate cuts, while good for borrowers, can lower NIMs as lending rates adjust faster than deposit rates, a factor that has already compressed margins for some banks. Some analyst ratings express caution, with two analysts rating HDFC Bank as "Reduce" and one as "Sell," citing insider selling and differing views on future performance. While HDFC Bank's asset quality remains strong with low Gross NPAs (1.15% as of March 31, 2026), ongoing competition and slower-than-anticipated credit growth (projected at 12-14%) could affect earnings visibility.

Analyst Views and Outlook

Beyond Deven Choksey's 'BUY' recommendation and INR 1,011 price target, overall analyst sentiment is predominantly positive. Many recommend "Strong Buy" with average price targets near INR 1,050-1,060, suggesting a potential 25-30% upside. However, recent coverage reveals a split, with some analysts initiating "Reduce" ratings. The bank's strategy to boost profitability metrics like RoA and EPS, especially by strengthening its retail deposit base, is crucial. Its success in navigating changing interest rates and maintaining cost discipline amid intense competition will determine if it can achieve its NIM expansion goals and justify its valuation, particularly as rivals like ICICI Bank are expected to post higher NIMs.
