HDFC Bank is India's largest private sector bank, providing retail and wholesale financial services. The bank operates through four primary segments: Retail Banking, Insurance Services, Wholesale Banking, and Treasury Services. Retail banking is the core business, focusing on deposit-taking and lending products such as mortgages, auto loans, personal loans, and credit cards. HDFC Bank is the leading credit card issuer in India and offers payment services via digital platforms and debit cards. The wholesale segment serves large corporations and public sector enterprises with trade finance, cash management, and working capital loans. Through its subsidiaries HDFC Life and HDFC ERGO, the bank also provides life and general insurance. The bank's business model relies on generating net interest income from the spread between lending rates and deposit costs. HDFC Bank maintains a cost advantage by utilizing a large base of low-cost current and savings accounts to fund its loan book. Following its merger with HDFC Limited, the bank is prioritizing retail deposit growth to replace higher-cost borrowings and lower its loan-to-deposit ratio. Management’s strategy involves accelerating retail loan growth in mortgages and digital lending while cross-selling banking products to mortgage customers. To drive efficiency, the bank invests in technology, including a proprietary generative AI platform, and relies on its maturing branch network to increase deposit productivity.
