HDFC Bank Ltd may raise at least Rs 2.2 trillion from public deposits and corporate bonds and an additional Rs 50,000 crore from similar documents to meet the regulator’s capital requirements with India’s largest mortgage lender and parent Housing Development Finance Corp Ltd merger are other prerequisites, said two people directly familiar with the bank’s plans.

“HDFC Ltd’s Rs 2.2-2.3 trillion borrowings are from various banks and must be repaid on the first consolidation day. This will be from deposits and bonds. Apart from this, at least Rs 50,000 crore will be raised from deposits to be used to Satisfy the statutory liquidity ratio (SLR) and capital adequacy requirement (CAR),” said the first person.

Indian regulations prohibit banks from borrowing from any other bank on their balance sheet, prompting HDFC Bank to raise funds to repay loans from its home country’s financial parent. HDFC Ltd is a non-banking financial company (NBFC) that borrows from other banks to lend to homebuyers. However, such borrowings may no longer remain on the bank’s balance sheet after the HDFC Bank merger. There are Rs 5 trillion of borrowings on the books surrounding HDFC Ltd, of which at least Rs 2.2 trillion are from different banks.

In addition, the people said that HDFC Bank would have to raise an additional Rs 50,000 crore to meet its SLR and other capital requirements, speaking on anonymity. SLR is the minimum percentage of deposits that a commercial bank must hold in liquid cash, gold or other securities.
