Background: HDFC Bank Ltd (NSE: HDFCBANK; BSE: 500180) is the largest private sector bank in terms of advances as well as deposits. The bank has presence in both segments viz. wholesale segment (commercial and transactional banking) and retail (branch banking) offering all major products business loans, vehicle loans, personal loans as well as credit cards. It was identified as Domestic Systemically Important Bank (apart from SBI & ICICI) by RBI in 2017.
The bank has been a strong player in the corporate segment with more than 20% growth in last three fiscals. However, the growth has not been at the cost of asset quality. The bank’s barometer to measure that i.e. average internal rating stood at 4.4 (scale of 1-10) for the corporate book as on Dec 31, 2020 which is equivalent to ‘AA’ rating by credit rating agencies.
Disbursements for the retail segment during the quarter had crossed pre-Covid levels with 20% yoy growth, meaning that the business is gaining traction for micro/small businesses. The bank’s retail book has mainly constituted of personal, auto & home loans. Interestingly, comparing the bank retail book from Mar-2020 to Dec-2020, it can be noticed that auto loans have been cut by 3.5% while home loans have grown by 5%. This further boosts the quality of loan book as houses fare better collaterals than vehicles.
Over the years, the bank has been focusing on augmenting the corporate loan book and the efforts have yielded results. The loan mix which was skewed towards retail book is now balanced.
Income: The bank has reported consistent growth in income figures during last 10 years. In fact, it has achieved at whopping 22% CAGR in operating revenue during 2010-20. In Q3FY21, the bank saw growth 15.1% growth in Net Interest Income (NII). It is difference between interest earned on loans & interest paid on borrowings/deposts; the two most important figures impacting profitability of a bank. Bank’s Net Interest Margin (NIM), measures how much spread a bank makes on a rupee lend, has remained stable at 4.2%.
Apart from interest, a bank also earns fee-based income from writing loans, distributing 3rd party products (like insurance), commissions, treasury gains, income from investments, etc.
Deposits: These are one of the cheapest sources of money for the bank; classified into current, saving and time deposits. Of these current and savings account (commonly known as CASA) balances are most crucial for a bank as these come at lowest costs. So for a bank, higher the CASA, the lower is cost of funding. HDFC Bank has been able to maintain its CASA at 42-43% consistently. CASA grew at 30% in Q3FY21; highest in last 5 quarters.
Adequate capitalization: RBI stipulates a minimum capitalization which all banks have to maintain to provide for in case of any unforeseen increase in bad loans. Capital Adequacy Ratio measures this which is ratio of capital to risk weighted assets. Against requirement of 11.075%, bank’s CAR stood at 19.1%. Bank’s CAR for Tier-1 capital was 17% (minimum requirement: 7.575%). Being identified as a Domestic Systemically Important Bank (D-SIB), it has to maintain additional 0.20% CAR.
Robust book quality: Growth in business is tough, quality growth in even more. And the best parameter to evaluate a bank’s book quality is NPA. The bank has been able to manage the GNPA% (of advances) at less than 1.4% and NNPA% at 0.4% levels during FY18-20. In Q3FY21, the GNPA% reduced noticeably to 0.8% and NNPA% to 0.1%. Compare this with GNPA% of HDFC Bank’s peers such as SBI 4.77%, ICICI Bank at 4.38%, Axis Bank at 3.44%. Though, the low figures for Q3 were also owing to directive by Honorable Supreme Court that those accounts that had not been declared NPA till August 31, 2020 should not be declared as NPA until further orders. However, the bank has been monitoring the actual NPA levels as per their assessment model, the GNPA% (proforma) will be 1.37%.
