HDFC Bank, India's largest private sector bank by assets and market capitalization, expects its net interest margin (NIM) to improve over the next two to three years as the impact of its merger with housing finance parent HDFC Ltd gradually diminishes, CEO Rajiv Kumar said at the bank's annual general meeting (AGM).
The merger between HDFC Bank and HDFC Ltd, completed in July 2023, was the largest transaction in India's corporate history, valued at approximately $40 billion. The combination brought the entire financial services conglomerate under a single entity, but it also temporarily compressed the bank's NIM—a key measure of lending profitability—as the higher-cost liabilities of the erstwhile HDFC Ltd were integrated into the bank's balance sheet. The deal created a banking behemoth with a combined balance sheet rivaling some of India's largest public sector banks.
Kumar indicated that this margin pressure is expected to ease progressively, with a full recovery anticipated within the next two to three years. NIM, which represents the difference between the interest income generated from loans and the interest paid on deposits, is a closely watched metric for banks. HDFC Bank's NIM had declined following the merger as the combined entity absorbed HDFC Ltd's long-tenor housing loans, which typically carry thinner spreads, alongside its costlier deposit book.
To support its next phase of growth, the lender outlined three strategic priorities: growing its deposit base, expanding retail and MSME (micro, small, and medium enterprises) lending, and leveraging technology to enhance operational efficiency and customer service. Building deposits has become a particularly important focus area for the entire Indian banking sector, where credit growth has been outpacing deposit growth, pushing up funding costs and intensifying competition for retail savings. The Reserve Bank of India has repeatedly flagged this credit-deposit gap as a area of supervisory attention.
