HDFC Bank’s results for the quarter ended 30 September 2026 contain two different descriptions of profit momentum. Standalone profit after tax grew 4.7% year on year. The bank also disclosed growth of approximately 12.6% when treasury trading gains are excluded. Both measures deserve a place in the discussion, because they answer different questions.
The useful insight is not to choose whichever percentage looks more attractive. It is to identify what changed in the earnings mix, whether the comparison is repeatable, and how much of the result depends on the starting period. A bank is several income engines operating together, not a single growth percentage.
The reported numbers, with their measurement basis
The following figures come from the bank’s 17 October release. Rupee amounts are converted from its rounded billion-rupee presentation into crore; small differences from more detailed financial tables can reflect rounding. The results discussed here are standalone Indian GAAP numbers, not consolidated group earnings.
| Measure | Q2 FY27 disclosure |
|---|---|
| Standalone PAT | ₹19,510 crore; +4.7% YoY |
| Net interest income | ₹34,620 crore, rounded; +9.7% YoY |
| Treasury trading gains | ₹780 crore versus ₹2,390 crore |
| NIM | 3.16% on total assets; 3.32% on earning assets |
| Gross / net NPA | 1.11% / 0.37% |
The missing bridge is treasury income
The release reports treasury trading gains of ₹780 crore, against ₹2,390 crore in the comparable quarter. The ₹1,610 crore reduction is a change in one income component. It helps explain why lending-income growth and total profit growth can tell different stories.
However, the reduction is before the full journey through expenses, provisions and tax. Simply adding the entire shortfall to this year’s after-tax profit would create an unreliable alternative PAT number. Use the bank’s own disclosed adjusted growth measure, and read its basis, rather than constructing a supposed like-for-like profit by mixing pre-tax income and after-tax earnings.
Two disclosed views of HDFC Bank profit growth
% year on year
| Label | Value (% year on year) |
|---|---|
| Reported standalone PAT | 4.7 |
| PAT excluding treasury gains | 12.6 |
Imagine a hypothetical shop that earned ₹100 from normal operations and ₹30 from selling an old vehicle last year. This year normal operations earn ₹112 and there is no vehicle sale. Total earnings fall from ₹130 to ₹112 even though the recurring business grew. This is an illustration of comparison mechanics, not HDFC Bank’s accounting or a claim that all treasury activity is exceptional.
For a bank, treasury management is a legitimate activity that can contribute gains and losses over time. Excluding it can illuminate the operating trend, but does not make it economically irrelevant. The complete view keeps reported earnings visible while examining the components underneath.
More interest income can coexist with a difficult margin discussion
Net interest income is the difference between interest earned and interest paid. A bank can expand that rupee amount by growing its earning assets even when the income earned per rupee of assets is under pressure. Volume and margin are therefore separate questions.
In a simplified hypothetical example, ₹100 of average earning assets at a 4% margin produces ₹4 of annual net interest income. If average earning assets rise to ₹120 while the margin falls to 3.6%, income becomes ₹4.32. Income rises 8% even though the margin falls. The illustration ignores the complexity of a real balance sheet; it shows why one number cannot substitute for the other.
The denominator also matters. HDFC Bank discloses NIM on total assets and on interest-earning assets. These are different bases. Comparing one bank’s total-asset measure with another bank’s earning-asset measure can produce an apparently precise ranking that is not comparable.
Deposit growth: a closing balance is not an average balance
A balance-sheet date is a photograph. An average balance describes the exposure carried through a period. A large deposit arriving near quarter-end can increase the closing figure without contributing much to the quarter’s average funding. The money is real, but its timing affects what the figure can explain.
This distinction helps investors connect funding growth with the income statement. Loan pricing, deposit costs and balance-sheet expansion work through time. A strong closing balance can support the next period while not fully explaining earnings already reported.
Ask whether deposits are growing across customer types and whether funding costs remain manageable. Faster expansion is not automatically better if the incremental funding is expensive or short lived. Equally, a slower headline can conceal improvement in the stability of funding. The result needs a mix-and-cost assessment.
Improving asset quality still needs a denominator check
A falling non-performing-asset ratio is useful evidence, but ratios combine a problem-loan numerator with an advances denominator. Loan growth, recoveries, write-offs, upgrades and new slippages can all affect the outcome. A lower ratio alone does not identify which force was dominant.
For illustration, ₹2 of problem loans divided by ₹100 of advances is 2%. With the same ₹2 numerator and ₹120 of advances, the ratio becomes about 1.67%. No problem loan was recovered in that example. This is why the next research step is to read the movement in the problem-loan stock and credit costs alongside the ratio.
Capital ratios answer yet another question: the size of the regulatory cushion relative to risk-weighted exposures. They should not be read as a return available to shareholders or as cash sitting idle and immediately distributable.
How this matters to a mutual fund investor
A bank result affects a fund through the actual holding, its weight and the change in the market’s expectations. The profit-growth rate of a company is not the return of its shares, and neither number is automatically the return of a diversified fund.
A hypothetical 5% fund position falling 4% would make a direct contribution of approximately minus 0.20 percentage point before other holdings and portfolio changes. That arithmetic is an exposure illustration, not an estimate of any fund’s HDFC Bank weight or a prediction of its share-price reaction.
The questions worth carrying into the next quarter
- Does lending-income growth remain supported by sustainable funding?
- Do margins stabilise on the same disclosed denominator?
- How much of the earnings comparison reflects treasury income and provisions?
- Do new slippages and credit costs agree with the asset-quality narrative?
- Is the valuation already assuming the improvement an investor expects?
These questions turn a quarterly headline into a research process. Reported PAT remains the accounting outcome. The adjusted comparison explains part of the change. Keeping both prevents a weak reading based on either the smallest or the largest percentage alone.
Reader questions
Did HDFC Bank’s underlying business grow only 4.7%?
The 4.7% figure is reported standalone PAT growth. The bank separately disclosed approximately 12.6% PAT growth excluding treasury trading gains; that adjustment helps explain the income mix but does not replace reported profit.
