Private bank stocks see a strong selloff this week after reporting weak Q1 margins. Time to add or stay clear?

Many private bank stocks, including HDFC Bank, Axis Bank, and Kotak Mahindra Bank, have suffered strong losses this week so far after reporting their April-June quarter (Q1FY27) results, which reflected their thinning net interest margins (NIMs) and modest credit growth.

The Nifty Private Bank index is down about 4% so far this week, with shares of HDFC Bank down over 8% and those of Axis Bank down about 7% this week till 1 pm on 22 July.

Shares of Kotak Mahindra Bank are down 2.5%, while ICICI Bank shares are flat for the same period.

Large private banking companies reported mixed NIM trends. Excluding ICICI Bank, HDFC Bank, Kotak Mahindra Bank, and Axis Bank, reported a decline on a QoQ basis in their NIMs, largely due to a change in their loan mix, wherein low-yielding corporate loans grew faster, and retail credit growth remained tepid. Spread compression also impacted their margins.

HDFC Bank’s NIM stood at 3.26% for the June quarter, down 12 bps QoQ. For Axis Bank, it was 3.46%, down 16 bps QoQ.

Kotak Mahindra Bank's NIM came at 4.53% for Q1FY27 compared to 4.67% for Q4FY26. ICICI Bank's NIM was 4.36% in Q1FY27, up 4 bps QoQ.

"Large private banks delivered a healthy but mixed Q1FY27. ICICI Bank remained the standout performer with strong earnings and stable margins, while HDFC Bank reported healthy business growth but weaker margins. Axis Bank and Kotak Mahindra Bank also posted steady operational performance despite margin pressure," said Pranay Aggarwal, Director and CEO of Stoxkart.

Brokerage firm Equirus Securities pointed out that entering Q2FY27, asset quality and capital remain strong, while deposit costs appear close to bottoming.

As per the brokerage firm, the key debate centres on the trajectory of NIM recovery into the second half of FY27, the durability of retail or unsecured loan growth, and whether corporate capex inflects sufficiently to sustain the current loan-growth momentum.

Experts expect the banking sector to remain under pressure in the short term due to margin compression and amid the prospects of a poor monsoon this year.

"Following the recent earnings, the banking sector may continue to witness some near-term pressure due to factors such as margin compression and the evolving monsoon outlook," Ajit Mishra, SVP- Research at Religare Broking, noted.

However, Mishra quickly added that the long-term fundamentals of leading banking names remain intact, and their positioning within the sector continues to be compelling.

"Long-term investors can use any earnings-led weakness or market volatility as an opportunity to gradually accumulate quality banking stocks in a staggered manner," said Mishra.

"Going forward, higher funding costs and intense deposit competition could keep net interest margins under pressure. However, strong asset quality, a high-quality advances mix and robust capital buffers should provide earnings stability," said Aggarwal.

Aggarwal believes increasing adoption of AI and digital technologies is expected to improve the operational efficiency and customer experience of banks, while healthy credit demand should support long-term growth.
