In the first session after the three largest private banks reported quarterly results on Saturday, Axis fell 4.1%, HDFC Bank 2.5% and ICICI Bank 1.2%, while state-owned banks rose more than 2%. The results themselves pointed in different directions.
India's biggest private banks reported very different quarters. The market treated them as one trade.
Axis Bank reported standalone net profit of 70.03 billion rupees for the quarter ended September, up 38% from a year earlier, with net interest income up 12% to 153.71 billion rupees. Its shares fell about 4.1% to 1,236.50 rupees on Monday.
That growth came off a depressed base. A year earlier, Axis's profit had fallen 26% to 50.90 billion rupees after a one-time provision of 12.31 billion rupees. This quarter's figure was also below the 71.80 billion rupee estimate compiled by Bloomberg, and the bank's net interest margin fell to 3.36% from 3.73%.
HDFC Bank, India's largest private lender, reported standalone net profit of 195.10 billion rupees, up 4.7%, and net interest income up 9.7% to 346.20 billion rupees. Its shares fell about 2.5%.
ICICI Bank reported standalone net profit of 148.43 billion rupees, up 20.1%, with net interest income up 17.7%. Its shares rose about 1% early in the session before turning lower, down about 1.2% by the afternoon.
The Nifty Private Bank index fell about 1.6% by late morning Mumbai time, while the index of state-owned banks rose more than 2%.
The margin story
The clearest difference among the three lies in net interest margins, the gap between what banks earn on loans and pay on deposits. ICICI reported a margin of 4.18%, Axis 3.36% and HDFC Bank 3.16% of total assets, or 3.32% of interest-earning assets.
HDFC's margin is the one investors are watching most closely, since it is the lowest of the three and its profit growth was below 5%. Analysts at Elara Capital said the worst may be over, while cautioning that a recovery in margins remains a challenge, and HDFC's chief financial officer said margins need "a couple of more quarters."
Asset quality held up across all three. Gross non-performing loans were 1.11% of loans at HDFC Bank, 1.16% at Axis and 1.20% at ICICI.
Why the sector sold
The selling was broad enough that no single bank's numbers explain it. Reported profit growth at Axis and ICICI did not protect their shares, though Axis's gain came off a weak base and missed estimates, and the gap between private and state-owned banks suggests investors were rotating within the sector rather than reacting to results alone.
The broader Indian market was also weak, with the Nifty 50 down about 1.2% by the afternoon.
Market implications
One reading is that results matter less than positioning. Private banks have been widely owned, state banks less so, and Monday's moves look like a shift in allocation that could reverse once results across the sector are in.
A second reading is that investors see margin pressure ahead. Deposit competition, slower loan growth and the cost of funding could squeeze private lenders' margins further, and headline profit growth this quarter does not resolve that.
What to watch
Margin guidance on the banks' analyst calls; deposit growth versus loan growth; the remaining private and state bank results this month; the Reserve Bank of India's next policy decision; and whether the gap between private and state bank stocks persists through the week. A second day of state-bank outperformance would point to rotation rather than a reaction to results.
