With the share swap, HDFC Bank will become one of the world's top 10 banks in terms of market capitalisation, as per Refinitiv data. HDFC Bank's shares have gained about 13% so far since the merger was announced, while the broader Nifty 50 index has risen over 8%. After the merger, HDFC Bank has no identified promoter. HDFC Bank CEO Sashidhar Jagdishan will head the combined company, while HDFC's Keki Mistry and Renu Sud Karnad will be on the bank's board. With the merger, HDFC Bank's total loan book will be over 22 trillion rupees, behind only that of State Bank of India, the country's largest lender. HDFC Bank will keep home loans at the centre of its growth strategy after the merger, with such credit likely to make up nearly a third of the lender's portfolio, two senior officials at the group had told Reuters in June.
