HDFC Bank Shares in Focus After $1.75 Billion Fundraise: What Investors Need to Know

HDFC Bank shares gained around 1% in morning trading on August 21 after the bank raised $1.75 billion, approximately ₹15,300 crore, through an overseas bond issue from its GIFT City branch.

The fundraising received orders worth nearly $7 billion, according to reports. That is about four times the final issue size and indicates strong demand from international investors.

But beyond the positive headline, an important question remains: Can this overseas funding help HDFC Bank manage the funding challenges that emerged after its merger with HDFC Ltd?

What Did HDFC Bank Announce?

HDFC Bank raised $1.75 billion by issuing senior unsecured bonds to overseas investors in two parts.

The bonds will be completed on August 26, 2026. HDFC Bank plans to use the money for overseas lending and other banking activities.

This is reportedly the largest overseas bond fundraising by an Indian bank since the 2008 global financial crisis. HDFC Bank had also raised $750 million in June, taking its recent overseas fundraising to around $2.5 billion.

Why Is HDFC Bank Raising Money Overseas?

Banks require funding before they can provide loans. HDFC Bank primarily obtains this money through customer deposits, borrowings and shareholders’ capital.

The HDFC Ltd merger added a large home-loan portfolio to HDFC Bank’s balance sheet. However, HDFC Ltd was a housing finance company and did not have access to low-cost current and savings account deposits like a bank.

Therefore, HDFC Bank inherited a large pool of loans along with HDFC Ltd’s relatively expensive borrowings. One of the bank’s major post-merger objectives has been to replace these borrowings with deposits.

The bank has made substantial progress. Borrowings declined from 21% of total liabilities in September 2023 to 11% in June 2026.

But another issue has emerged: HDFC Bank’s deposit mix has become more dependent on fixed deposits.

Is HDFC Bank Struggling to Raise Deposits?

HDFC Bank is not facing an absence of deposit growth. Its deposits increased strongly in Q1 FY27:

Closing deposits reached ₹31.71 lakh crore at the end of June 2026. This suggests that HDFC Bank continues to attract a large amount of customer money.

The concern is mainly about the cost and composition of those deposits.

HDFC Bank’s CASA ratio declined from 38% in September 2023 to 32% in June 2026. CASA includes current and savings account deposits, which are generally cheaper than fixed deposits.

Meanwhile, the bank’s closing time deposits grew 17.4% year-on-year. This means a larger part of deposit growth is coming from fixed deposits, on which the bank normally pays higher interest.

Therefore, the post-merger funding situation has two sides:

• HDFC Bank has successfully reduced its dependence on borrowings.
• However, its share of low-cost CASA deposits has continued to decline.

Can the $1.75 Billion Bond Issue Solve the Deposit Problem?

Not directly. The bonds provide HDFC Bank with another source of money, but they do not improve its CASA ratio or retail deposit franchise. The fundraising can still help by:

• Providing stable funding for three and five years
• Diversifying the bank’s sources of money
• Supporting foreign-currency loans
• Improving access to global capital markets
• Reducing dependence on domestic deposits for foreign-currency lending

However, the bonds are still borrowings. HDFC Bank must pay interest and repay the principal irrespective of how profitably it deploys the money.

The fundraising can improve funding flexibility, but it cannot replace the long-term need to attract more low-cost deposits.

Was the Overseas Bond Issue Priced Efficiently?

Instead of comparing the bond coupons with HDFC Bank’s overall cost of funds, it is more useful to examine how much additional return global investors demanded over US government bonds.

The three-year bonds were reportedly priced at approximately 88 basis points above comparable US Treasury yields, while the five-year bonds were priced at around 100 basis points above US Treasury yields.

One basis point is equal to 0.01 percentage point. Therefore:

• 88 basis points means 0.88 percentage point.
• 100 basis points means 1 percentage point.

US Treasury bonds are treated as the benchmark for dollar borrowing. The spread above the Treasury yield reflects the additional return investors demand for taking HDFC Bank’s credit and liquidity risk.

The reported order book reached nearly $7 billion against an issue size of $1.75 billion. This suggests that global investors were willing to lend substantially more money than HDFC Bank ultimately accepted. The strong demand is important because it indicates:

• Confidence in HDFC Bank’s ability to repay
• International acceptance of its credit profile
• Access to large amounts of long-term dollar funding
• Potential ability to raise foreign capital again when required

However, strong demand for bonds reflects confidence in HDFC Bank as a borrower. It does not automatically mean that the bank’s profitability or share price will improve.

How Can HDFC Bank Use These Dollars?

HDFC Bank can deploy the funds in several ways. It can provide dollar-denominated loans to companies engaged in imports, exports or overseas projects. In this situation, the bank receives interest and principal in dollars and can use those dollars to repay bondholders.

This creates a natural currency match:

The bank can also convert the dollars into rupees and use them for domestic lending. But doing so creates currency risk because the bonds must eventually be repaid in dollars. That is where RBI’s special swap facility becomes relevant.

How Does RBI’s Dollar-Rupee Swap Facility Help?

RBI introduced a special dollar-rupee swap facility in June 2026 for eligible overseas foreign-currency borrowings raised by banks.

Under the facility, a bank can give its dollars to RBI and receive rupees. At the end of the agreed period, the bank returns the rupees and receives its dollars back.

This protects the bank from uncertainty caused by a fall in the rupee.

RBI charges a fixed swap premium of 1.5% per annum, compounded half-yearly. The swap period can match the maturity of the borrowing, subject to a maximum of five years.

HDFC Bank’s three-year and five-year bonds appear to meet the facility’s basic maturity requirements. However, the bank has not publicly disclosed whether it will use the RBI facility for the entire $1.75 billion.

The bank may use a combination:

• Retain some funds in dollars for foreign-currency lending
• Convert some funds into rupees using RBI’s swap
• Use other currency hedging arrangements where necessary

Therefore, the RBI facility is a useful option, but it should not be assumed that the entire bond issue has already been swapped.

How Can This Fundraising Affect HDFC Bank’s Earnings?

Fundraising does not generate profit on its own. HDFC Bank must deploy the money into loans or other earning assets.

The economics are relatively simple: Interest earned on loans minus bond interest, hedging expenses, operating costs and credit losses equals the bank’s profit spread.

For example, if HDFC Bank deploys the money into dollar loans earning only slightly more than the bond coupon, the profit contribution may remain limited after other expenses. The benefit will depend on:

• Yield earned on foreign-currency loans
• Effective currency-hedging cost
• Credit quality of borrowers
• Speed at which the funds are deployed
• Maturity matching between loans and bonds

Investors should therefore focus on the return HDFC Bank earns from these funds, not only on the size of the fundraising.

Is the Fundraising Positive for HDFC Bank Shareholders?

There are clear positives. The large order book shows that international investors remain willing to lend significant money to HDFC Bank. The issue also provides stable dollar funding and gives the bank greater flexibility in managing its balance sheet.

However, the fundraising does not solve every post-merger challenge.

It does not directly improve HDFC Bank’s CASA ratio, lower the cost of domestic deposits or increase return ratios. It also creates a fixed interest obligation that must be serviced over the next three to five years.

The transaction is therefore positive for funding access and investor confidence, but its earnings impact will depend on how the money is deployed.

Can the Bond Issue Trigger a Fresh Rally in HDFC Bank Shares?

The bond issue can support short-term sentiment because it signals strong access to international funding. This is particularly relevant after the stock’s recent weakness.

However, the fundraising alone may not be enough to create a sustained rally. For a more durable recovery, investors will likely look for improvement in:

• Deposit growth relative to loan growth, CASA ratio
• Net interest margin, Return on assets
• Return on equity, Post-merger operating performance

The bond issue shows that HDFC Bank can raise money. The next question is whether it can convert that money into profitable growth.

What Should Investors Track Next?

• Use of funds: Where HDFC Bank deploys the $1.75 billion and the returns it earns from those loans.
• Currency risk: Whether the bank keeps the funds in dollars or converts them into rupees using RBI’s swap facility.
• Deposit position: Whether deposit growth keeps pace with loan growth and if the CASA ratio improves.
• Profitability: The impact on net interest margin, return on assets and return on equity.

Conclusion

HDFC Bank’s $1.75 billion bond issue is an important funding and confidence event. Strong global demand shows that overseas investors remain comfortable lending to the bank, while the three- and five-year maturities provide relatively stable dollar funding.

But the transaction does not directly solve HDFC Bank’s challenge of attracting low-cost deposits. It improves funding flexibility, not deposit quality.

For shareholders, the eventual benefit will depend on whether HDFC Bank can deploy the money at an adequate return after interest, hedging and credit costs. A sustainable improvement in the stock will still depend more on CASA, margins and post-merger return ratios than on the fundraising headline alone.
