ICICI Bank vs HDFC Bank: FY26 margin gap in focus

Private bank comparisons are trending again, with ICICI Bank vs HDFC Bank dominating retail investor threads. The discussion is not about who is “best” in a vacuum, but which set of metrics matters more right now. Users are placing HDFC Bank’s scale and market value on one side, and ICICI Bank’s profitability and margin profile on the other. The Q4FY26 prints are being used as the most recent scorecard, along with FY26 consolidated figures shared widely. Several posts also tie HDFC’s recent efficiency and CASA pressure to post-merger normalisation, without claiming a single quarter tells the whole story. The overall tone is that the gap has narrowed on some fronts, while it has widened on profitability efficiency. Below is a fact-based summary of what is being quoted, and why it is moving sentiment.

Market cap and the “size premium” argument

On market value, HDFC Bank is being cited at around Rs 1,231,000 crore market capitalisation, versus ICICI Bank at around Rs 968,000 crore. This difference is often presented as the market assigning a “scale premium” to HDFC. Commenters also point out that HDFC leads in balance sheet size and deposits, which can support that premium. In the same discussions, users acknowledge that market cap does not automatically mean higher profitability per unit of assets. The comparison is therefore framed as scale and franchise depth versus efficiency and returns. Some posts explicitly note that HDFC is “stabilizing post-merger,” implying investors are watching a transition period. The market cap debate is also linked to whether margins and ROA can converge back toward peers.

FY26 consolidated snapshot shared on social media

A frequently shared table of FY26 consolidated numbers shows HDFC Bank leading on most scale metrics. Revenue is quoted at Rs 3.49 lakh crore for HDFC Bank versus Rs 1.95 lakh crore for ICICI Bank. Net profit is quoted at Rs 79,219 crore for HDFC Bank versus Rs 57,936 crore for ICICI Bank. Deposits are quoted at Rs 31.00 lakh crore for HDFC Bank versus Rs 18.30 lakh crore for ICICI Bank. On gross NPA, the same snapshot quotes HDFC at 1.15% versus ICICI at 1.40%. This is why many posts conclude HDFC “outperforms on scale,” even when the profitability debate remains open.

Q4FY26 profit: bigger absolute number vs faster momentum

For Q4FY26, HDFC Bank’s net profit is being cited at about Rs 19,220 to Rs 19,221 crore, up around 9% year-on-year. ICICI Bank’s net profit is being cited at about Rs 13,700 to Rs 13,702 crore, also up around 8% to 9% year-on-year. The simple takeaway repeated online is that HDFC delivers the larger absolute profit, while ICICI’s growth momentum shows up more strongly in certain line items. Some threads also flag a separate point that HDFC’s net profit growth of about 5% to Rs 19,060 crore was discussed alongside a ROA slip to about 1.9% in another circulating excerpt. Because multiple posts quote slightly different figures, the debate often focuses on direction rather than one exact number. Still, the consensus in the chatter is that profitability efficiency is where ICICI is pulling ahead.

Net interest income and NIM: the core of the ICICI bull case

HDFC Bank’s Q4FY26 net interest income (NII) is widely quoted at around Rs 33,080 to Rs 33,082 crore, up roughly 3% year-on-year. Its net interest margin (NIM) is quoted at 3.38%, with a sequential improvement of about 3 basis points. ICICI Bank’s Q4FY26 NII is widely quoted at about Rs 22,979 to Rs 22,980 crore, up about 8% to 8.4% year-on-year. ICICI’s NIM is quoted at 4.32%, with a sequential improvement of about 2 basis points, and repeatedly described as “industry-leading” in these posts. This NIM gap is central to the narrative that ICICI is monetising its balance sheet more efficiently at this stage of the cycle. Commenters often link this directly to funding mix and operating execution rather than pure loan growth.

CASA ratio: why the funding mix is being debated

CASA is a major flashpoint because posts cite different points for each bank, while agreeing on the broad direction. HDFC Bank’s CASA is cited around 34.1% for the March 2026 quarter, while other posts describe it as settling near 37.5% or roughly 33% amid pressure. ICICI Bank’s CASA is described as maintaining a baseline near 39.0% in some threads, while another widely shared snapshot pegs it at 41.4%. The explanation circulating is that “savvy savers” have shifted cash toward higher-yielding fixed deposits and mutual funds, pressuring CASA for large banks. For ICICI, users attribute resilience to “automated corporate salary account onboarding ecosystems,” as phrased in the posts. Regardless of the exact point estimate, the community takeaway is that ICICI is currently being credited with a relative funding advantage. That funding advantage is then tied back to the sustained NIM gap.

Growth metrics: loans, deposits, and what “growth” means here

Loan growth is another metric where ICICI is repeatedly said to be ahead in the latest quarter comparisons. HDFC Bank’s credit growth is quoted at about 12% year-on-year. ICICI Bank’s credit growth is quoted at about 16% year-on-year, and another post cites growth at about 15.8% for the quarter snapshot. Deposits show the opposite pattern in scale, with HDFC deposits cited around Rs 3,105,000 crore and ICICI deposits around Rs 1,794,000 crore in the Q4FY26 snapshot. YoY deposit growth is quoted at about 14% for HDFC versus about 11% for ICICI in the same table. This is why discussions often separate “growth rate” from “franchise size,” treating them as different strengths. Many posts frame HDFC as having the stronger deposit franchise, while ICICI is gaining on credit expansion and margin capture.

Asset quality: GNPA vs NNPA and the fine print

On asset quality, the debate is nuanced because different measures point in different directions. Gross NPA (GNPA) is cited at 1.15% for HDFC Bank versus 1.40% for ICICI Bank in the Q4FY26 table and in the FY26 consolidated snapshot shared. Net NPA (NNPA) is cited at 0.38% for HDFC Bank versus 0.33% for ICICI Bank, which gives ICICI a slight edge on net stressed assets. Multiple posts describe both banks as maintaining “pristine” or very strong asset quality in the current cycle. This is important because it keeps the focus on margins, funding mix, and return ratios rather than on credit shocks. Social media users also mention HDFC’s lower provisions supporting its Q4 profit growth, without adding extra numbers. Overall, asset quality is not being used as the deciding factor between the two in these threads.

ROA and efficiency: the metric driving the “ICICI gap” narrative

Return on assets is the clearest divider in the social media commentary. HDFC Bank’s ROA is quoted in a range, including about 1.8%, about 1.96%, and a separate excerpt referencing a slip to about 1.9%. ICICI Bank’s ROA is quoted higher, including about 2.25% and about 2.4%, and described as “best-in-class” in some posts. The implied message is that ICICI is converting its balance sheet into profits more efficiently at this point. Some threads also link HDFC’s lower ROA and higher cost pressures to the merger, saying it has impacted cost-to-income and ROA versus ICICI. For ICICI, cost-to-income is cited around 39.9% in one snapshot, alongside a CET1 ratio of 16.35% and ROE of 16.6%. Users treat ROA as the cleanest way to compare profitability across different sizes.

Key numbers table cited in the debate

The following Q4FY26 snapshot is being circulated widely and underpins most side-by-side arguments.

These figures are being used to argue that HDFC leads on size and absolute profit, while ICICI leads on margins and ROA. The table also explains why CASA is getting so much attention, because the funding mix can affect NIM and returns. It is also why some posts say HDFC’s “balance sheet strength” is intact even if near-term efficiency looks softer. Meanwhile, ICICI’s supporters point to the consistent NIM and higher ROA as the market’s preferred combination right now. The most grounded conclusion in the threads is that the two banks are winning on different axes. Investors are therefore choosing between scale stability and profitability efficiency, based on their own time horizon.
