Q1 FY27 (April–June 2026) · Banking sector analysis
HDFC Bank is the largest private bank in India and one of the most widely held stocks in the country. This quarter, it also earned the thinnest lending margin of every major private bank, and grew profit just 5%, while smaller rivals grew 16% to 26%.
ICICI, with a balance sheet a little over half the size of HDFC's, now earns about 35% more profit per rupee it owns. That single fact says more about Indian banking today than any profit headline. Here's why the giant slipped, and the three numbers that explain the whole sector.
First, What Just Happened
Nearly every big bank reported higher profits this quarter: IDFC First's jumped 132%, Kotak's 26%, Axis's 23%. But the stock market reacted very differently; several of the biggest banks saw their shares fall sharply the next day. Axis dropped 5%, Kotak 2%.
For most of the big banks, the profit jump owed more to lower provisions than to a step-up in core lending income. They came mainly from banks setting aside far less money for bad loans. The market could see the difference, and wasn't fooled. To see what it saw, you only need three numbers.
The Three Numbers That Matter
You can skip a dozen banking ratios. These three do most of the work.
NIM - how much a bank earns on each rupee of assets it holds. Net Interest Margin is the interest a bank earns minus the interest it pays, measured against the assets it holds. Wider is better. This is the bank's core profit engine.
GNPA - how much of its lending has gone bad. Gross Non-Performing Assets is the share of loans the borrower has stopped repaying. Lower is safer.
ROA - how much profit it squeezes from its total size. Return on Assets is the great equaliser: it measures profit against how big the bank is, so you can compare a giant and a tiny bank fairly. Around 1.5% or higher is strong.
Why HDFC, the Giant, Now Earns the Least
HDFC Bank's margin fell to 3.26% this quarter, its lowest ever. The cause traces back to one event: its 2023 merger with parent HDFC Ltd.
The merger loaded the bank with a large pile of expensive borrowings, which cost far more than ordinary deposits. At the same time, its most valuable funding source was shrinking. Banks earn the fattest margins on CASA, the cheap money sitting in current and savings accounts, which costs them almost nothing. HDFC's share of that cheap money slid from around 38% to roughly 32% as savers moved cash into higher-return fixed deposits. Costlier funding plus less cheap money equals a squeezed margin. The bank still has ₹40,000–50,000 crore of that expensive borrowing left to run off over the next two years.
So HDFC isn't earning less because it lends badly. Its bad-loan number, 1.17%, is among the sector's cleanest. It earns less because its funding turned expensive at the worst possible time.
How the Six Compare: Q1 FY27
| Bank | Profit (YoY) | NIM | GNPA | ROA |
| ICICI Bank | +16% | 4.36% | ~1.4% | 2.49% |
| Kotak Mahindra | +26% | 4.53% | 1.18% | 2.14% |
| HDFC Bank | +5% | 3.26% | 1.17% | 1.85% |
| Axis Bank | +23% | 3.46% | 1.28% | 1.51% |
| IDFC First | +132% | 5.96% | 1.51% | ~1.06% |
| Bank of India (PSU) | +36% | 2.52% | ~2% | ~1.0% |
Read down the ROA column and the real ranking appears, one that the profit-growth column hides. ICICI, not HDFC, is the sector's strongest earner: wide margins, clean loans, and the group's best return. That combination is why the market rewarded its result and shrugged at bigger profit jumps elsewhere.
Two rows need a second look. IDFC First's 132% jump is the headline of the season, and it is largely real: a ₹515 crore credit-guarantee claim was fully offset by a matching voluntary provision, so it added almost nothing to profit. The jump came from 21% NII growth, a wider margin and provisions down 31%. Its 5.96% margin also looks huge, but that is because it lends to riskier borrowers who pay more; a fat margin means little if those loans sour, which is why you read NIM and GNPA together. Bank of India, state-owned, shows the gap PSUs still carry: even in a strong quarter, its margin and return sit well below the private leaders.
What this Means If You're Looking at Bank Stocks
Two takeaways an investor can actually use.
Don't trust the profit headline alone. A 132% or 36% jump can rest on one-offs that won't repeat. Check whether the margin and the return are genuinely improving, or whether the bank just provisioned less this quarter.
ROA and NIM together beat the profit figure every time. A bank holding a wide margin and a strong return is compounding quietly. One leaning on one-time gains is not. That gap is exactly what the market is pricing when it lets a "record profit" stock sit flat.
Part of the sector is still absorbing a margin squeeze it didn't cause; the RBI's 125 bps of cuts through 2025 did, by pushing loan rates down faster than deposit rates. That headwind hits everyone. What separates the banks is who can hold their returns steady through it, and this quarter, size was no protection at all.
