HDFC Bank Q2 Results FY27: Why Profit Grew Just 4.7%

HDFC Bank's latest quarterly results tell an interesting story. The bank is attracting more deposits, lending more money and maintaining relatively healthy asset quality. Yet its profit is growing much more slowly than its business.

In Q2 FY27, HDFC Bank's deposits jumped 18.8% and gross loans grew 16.3% year-on-year. But standalone net profit increased just 4.7% to ₹19,510 crore.

Investors appeared unconvinced. HDFC Bank shares fell as much as 2% in early trading on October 19, 2026, after the results were announced over the weekend.

So, what's holding back profits? And more importantly, are the underlying numbers better than the headline suggests?

HDFC Bank Q2 FY27 Results: Key Financial Highlights

HDFC Bank announced its results for the July–September 2026 quarter on October 17. Here is how the bank performed compared with the same period last year.

At first glance, the results look reasonably healthy. Deposits and lending are growing at double-digit rates, while bad-loan ratios have improved.

But to understand why profit growth was much slower, we need to look at how the bank actually makes money.

Why Did HDFC Bank's Net Profit Grow Only 4.7%?

Think of a bank's business in simple terms. It collects money from depositors, pays them interest, and lends money to borrowers at a higher interest rate. The difference is a major source of its earnings.

In Q2 FY27, HDFC Bank earned ₹34,620 crore in net interest income, 9.7% more than a year ago. So the core interest business did grow. But not all that additional income reached the bottom line.

Here's a simplified breakdown of what changed compared with Q2 FY26.

Calculated from HDFC Bank's reported standalone results; rounded figures.

This explains the puzzle. The bank earned around ₹3,070 crore more from its core interest business, but other changes absorbed much of that increase.

And one of the biggest factors was treasury income.

The important difference between 4.7% and 12.6% profit growth

HDFC Bank's treasury trading gains fell from approximately ₹2,390 crore in Q2 FY26 to just ₹780 crore in Q2 FY27.

Treasury gains generally come from trading and valuation movements in financial investments. Unlike the regular interest earned from lending, these gains can fluctuate significantly between quarters.

That makes year-on-year profit comparisons tricky.

In fact, HDFC Bank reported that profit excluding treasury trading gains grew approximately 12.6%, compared with its reported profit growth of 4.7%.

This doesn't mean the 4.7% figure is misleading or that investors should ignore treasury income. It simply means the bank's underlying profit comparison looks stronger when these trading gains are excluded.

The next question is whether that stronger growth can continue.

HDFC Bank Deposits Grew 18.8%. Is Its Funding Problem Improving?

For a bank, lending money is only half the job. It must also raise enough deposits to finance those loans. And this is where HDFC Bank delivered an encouraging result.

Over the past year, its deposit base increased by approximately ₹5.26 lakh crore, while gross advances increased by around ₹4.50 lakh crore. That means deposits grew faster than loans.

Using period-end gross advances divided by deposits, the ratio improved from approximately 99% a year ago to 97% in September 2026.

This suggests the bank is making progress in bringing funding growth closer to lending growth, an important consideration following its merger with HDFC Ltd.

But there's a catch. Not every deposit costs the bank the same amount.

Money kept in current and savings accounts, commonly called CASA deposits, is generally cheaper for banks than fixed deposits.

HDFC Bank's CASA deposits grew 10.8% year-on-year, while term deposits grew much faster at 22.8%. Consequently, its CASA ratio fell from 33.9% to 31.6%.

In simple terms, HDFC Bank is attracting deposits rapidly, but a larger share of its funding now comes from deposits that typically carry higher interest costs.

The deposit challenge is therefore improving in quantity, but the funding mix still needs attention.

And that brings us to another important number: the bank's net interest margin.

Why Are HDFC Bank's Net Interest Margins Under Pressure?

Net interest margin, or NIM, measures how much net interest income a bank earns relative to the assets used to generate that income.

Higher margins generally mean the bank is earning more from those assets after accounting for interest costs.

HDFC Bank reported a NIM of 3.16% based on total assets, or 3.32% when calculated on interest-earning assets. The broader trend shows pressure on lending profitability.

The bank's yield on assets declined from 7.8% in September 2025 to 7.6% in September 2026. Its reported cost-of-funds measure also declined, from 4.6% to 4.4%, but the mix and timing of lending and funding continued to matter.

Why does this deserve attention?

Because a bank can increase lending significantly without seeing an equally strong rise in interest income if the return earned on its assets is weakening.

That's part of the challenge visible in these results. Gross advances grew 16.3%, while net interest income increased 9.7%. These are different measures, with period-end loans compared against quarterly income, so their growth rates should not be expected to match exactly.

Still, their movement makes the direction of margins worth watching. For HDFC Bank, future profitability will depend not just on lending more, but on earning an attractive margin on that lending.

Where Is HDFC Bank's Loan Growth Coming From?

Another encouraging part of the results is the bank's expanding lending business, particularly among smaller businesses.

Small and mid-market advances grew 23.5% year-on-year, while business banking advances increased 28.1%. Corporate and other wholesale advances grew 16.4%.

This matters because growth across different customer segments provides opportunities beyond traditional large corporate lending. However, one detail deserves attention.

The bank reported 16.9% growth in its non-mortgage retail assets, but this included ₹54,800 crore of foreign currency non-resident (FCNR) leverage loans. Excluding these loans, the bank reported growth of 9.1% in that retail-asset category.

So while the overall loan book is expanding, investors should distinguish between growth in conventional retail lending and growth supported by specific financial products.

The important test will be whether HDFC Bank can maintain strong lending growth while improving margins and controlling credit risk.

Are HDFC Bank's Bad Loans Coming Down?

On the surface, asset quality improved.

The gross non-performing asset (NPA) ratio declined from 1.24% a year earlier to 1.11% in September 2026. Net NPAs stood at 0.37% of net advances.

That's reassuring because bad loans can quickly erode bank profits through higher provisions. But there's an important distinction between the percentage of bad loans and the actual amount.

HDFC Bank's gross NPAs stood at approximately ₹35,810 crore in September 2026, compared with ₹34,289 crore a year earlier.

In other words, the bad-loan ratio improved even though the absolute amount of gross NPAs was slightly higher year-on-year. The larger loan book partly explains the improved ratio.

This doesn't suggest an immediate deterioration in the bank's financial health. It simply means investors should examine both numbers rather than relying on the NPA ratio alone.

What Do HDFC Bank Q2 Results Mean for Its Share Price?

The early market reaction was cautious. HDFC Bank shares declined as much as 2% on October 19, although broader banking stocks also faced selling pressure.

But a one-day share-price movement doesn't necessarily tell us whether a bank's quarterly performance was fundamentally good or bad.

There are positive developments here. Deposits are growing faster than loans, core interest income is increasing, asset-quality ratios remain relatively healthy, and profit growth excluding treasury trading gains is stronger than the headline figure.

On the other hand, the falling CASA ratio and pressure on margins raise questions about how quickly stronger business growth can translate into better returns for shareholders.

HDFC Bank reported a return on equity of 13.5% for the quarter. That metric matters because bank valuations depend partly on how efficiently lenders generate profits from shareholders' capital.

For investors, the next few quarters will be about whether HDFC Bank can turn its expanding balance sheet into consistently stronger earnings and returns.

What Should Investors Watch After HDFC Bank's Q2 Results?

Four indicators deserve the closest attention:

1. Deposit mix: Can HDFC Bank increase its share of low-cost current and savings account deposits?
2. Net interest margins: Will the bank earn more from its lending and investment assets relative to its funding costs?
3. Sustainable earnings growth: Can profit growth remain healthy without relying on unpredictable treasury gains?
4. Asset quality: Can the bank maintain controlled credit costs while expanding lending to retail and business customers?

HDFC Bank's Q2 FY27 results are neither a clear disappointment nor an unquestionable turnaround.

The bank is making visible progress in growing deposits and loans, and its profit growth excluding treasury trading gains looks healthier than the reported 4.7% increase. But growth alone will not determine what happens next.

The real test for HDFC Bank is whether its rapidly expanding business can start generating stronger, more consistent profits.
