Post the merger, there will be a combined customer base of HDFC Bank and HDFC and they will be offered a number of financial products—savings accounts, mortgages or home loans, life insurance, general insurance, health insurance, credit cards, investment products and personal loans. “The merger will benefit both the entities. It would create the required scale and synergies, and bring back lustre to the group stocks. However, profitability of the merged entity may take a hit as the borrowing cost for HDFC will increase while book yield comes down. While there will definitely be cost synergies through the merger, it might take time for the market share to increase. The management would still have to prove the benefits of the merger through operating performance,” says a banking analyst on condition of anonymity.
