A public sector bank in India is a bank where the Government of India owns a majority stake. There are 12 of them today, and this guide covers what they are, the full list after the 2019-2020 mergers, how they differ from private banks — and, if you are here as an investor, the specific numbers that separate a genuine PSU bank turnaround from one still working through old problems.
Public sector banks (PSBs) are banks where the Government of India holds a majority stake — more than 50% of the shares. There are 12 of them today after the 2019-2020 mergers, led by State Bank of India. As investments, they trade at a historical valuation discount to private banks due to weaker legacy asset quality and government-influenced lending. That gap has narrowed for banks that have genuinely cleaned up their books, which is why NPA trends and capital ratios matter more here than for almost any other sector.
A public sector bank is a bank in which the Government of India holds a majority ownership stake — typically well above the 50% threshold. Control sits with the government rather than with private promoters or public shareholders, which shapes how the bank lends, raises capital and adopts technology. Public sector banks are also called PSBs, PSU banks, government banks or nationalised banks.
They came about in two big waves of nationalisation — 14 banks in 1969 and six more in 1980 — and were then consolidated through mergers, most recently in 2019-2020, which cut the count from 27 to the current 12.
There are 12 public sector banks in India after the last round of mergers:
IDBI Bank is not on this list — it is now classified as a private sector bank after LIC took a controlling stake, and the government has announced plans to exit it entirely. For how the other side of the sector works, see our guide to private sector banks in India.
Beyond majority government ownership, PSU banks differ from private banks in a few ways that matter for an investor: lending decisions have historically been more exposed to policy priorities and priority-sector mandates, technology adoption has generally lagged private peers, and periodic capital raises via government-backed share issuances have diluted existing shareholders. None of this makes PSU banks uninvestable — it just means the checklist has to go further than "cheap valuation, big brand."
PSU banks have long traded at lower price-to-book multiples than private banks, largely earned during the mid-2010s corporate NPA crisis when several PSU banks' bad loan books ballooned. Since then, a subset of PSU banks — particularly the larger ones — has meaningfully improved provision coverage and reduced net NPAs, and the market has re-rated some of them accordingly. The discount hasn't disappeared, and it shouldn't be treated as automatically closing for every name in the category.
| Metric | What it tells you |
|---|---|
| Gross & net NPA trend | Direction matters more than the absolute number — improving over several quarters vs. stagnant or worsening |
| Provision coverage ratio | Higher coverage means bad loans are already provisioned for, reducing future earnings shocks |
| Capital adequacy ratio | A thin buffer raises the odds of another dilutive capital raise |
| Return on assets / return on equity | The clearest single signal of whether the bank is actually converting its book into profit |
| Exposure to stressed sectors | Concentration in a sector under stress (e.g. certain infrastructure or power lending) is a forward-looking risk, not just a historical one |
This sits on top of — not instead of — the general stock screening framework we use across sectors: growth, ROE, debt, promoter behaviour and valuation still apply, with government ownership standing in for the promoter-holding check.
Private banks generally offer more consistent execution and less policy-driven variability, at a valuation premium. PSU banks offer size, government backing that effectively rules out failure risk, and — for the improved names — a valuation that hasn't fully caught up to the balance sheet quality. Neither is categorically better; they suit different theses. Treating "public sector banks" as one undifferentiated basket, buying or avoiding all 12 together, is the most common mistake here.

Public sector banks (PSBs), also called government or Indian public sector banks, are banks where the Government of India holds a majority stake — currently 12 banks after a series of mergers, led by State Bank of India, Punjab National Bank, Bank of Baroda and Canara Bank. They differ from private banks primarily in ownership, risk appetite and historically higher exposure to bad loans.
It depends entirely on the individual bank's balance sheet quality, not the PSU label itself. Some PSU banks have cleaned up significantly since the mid-2010s NPA crisis and now trade at more reasonable valuations than private peers; others still carry weaker asset quality. Screen each one on its own numbers rather than treating "PSU bank" as a single investment thesis.
The market has historically applied a valuation discount to PSU banks due to weaker historical asset quality, government-influenced lending decisions, slower technology adoption, and periodic capital dilution through government-backed share issuances. Some of that gap has narrowed as balance sheets improved, but the discount hasn't disappeared.
There are 12, following the 2019-2020 mergers that consolidated 27 PSU banks into fewer, larger entities: State Bank of India, Punjab National Bank, Bank of Baroda, Canara Bank, Union Bank of India, Bank of India, Indian Bank, Central Bank of India, Indian Overseas Bank, UCO Bank, Bank of Maharashtra and Punjab & Sind Bank. State Bank of India is by far the largest. IDBI Bank is no longer counted as a PSU bank.
Beyond the standard growth, ROE and valuation checks, look specifically at gross and net NPA trends, provision coverage ratio, capital adequacy ratio, and how much of the bank's book is exposed to stressed sectors. A PSU bank improving on all four is a very different story from one merely riding a sector-wide re-rating.
