HDFC Bank is India's largest private-sector bank by assets and deposits. Promoted by mortgage lender HDFC Ltd in 1994 and built under Aditya Puri's 26-year tenure into a byword for credit discipline, it absorbed its own parent in July 2023, adding a large home-loan book and subsidiaries in insurance and asset management. Today it serves retail, small-business and corporate customers through 9,689 branches and DBUs and a heavily digital channel mix. The absolute largest private sector bank in India was founded in 1994, completely transforming the Indian economy by bringing highly aggressive, modernized retail banking to the massive, emerging middle class.
HDFC Bank makes money mainly from the spread between what it earns on loans and investments and what it pays depositors. Net interest income was roughly two-thirds of FY2025-26 net revenues; the rest came from fees and commissions on cards, payments, third-party distribution and transaction banking, plus treasury and foreign-exchange income. Its three reporting engines are retail banking (mortgages inherited from HDFC Ltd, personal and vehicle loans, credit cards, savings accounts), wholesale banking (working capital, term loans, cash management and trade finance for companies) and treasury. Listed subsidiaries such as HDFC Life, HDFC ERGO, HDFC Asset Management and HDB Financial Services add consolidated earnings.
