What makes a bank a PSU bank in India?

A public sector undertaking (PSU) bank in India is one where the Government of India holds more than 50% of the equity stake. This ownership structure means the government appoints the top management (with RBI concurrence), the bank must align its lending priorities with government policy directives, and any large capital raising must either come from the government or dilute government's stake below the threshold. State Bank of India, Bank of Baroda, Punjab National Bank, and Canara Bank are among the largest PSU banks in India.

What was the RBI's Asset Quality Review (AQR) of 2015?

The RBI's Asset Quality Review (AQR), initiated in late 2015 under then-Governor Raghuram Rajan, was a systematic examination of the loan books of Indian banks — primarily PSU banks — to assess whether loans classified as 'standard' were being correctly reported or were effectively non-performing. The AQR revealed that a large volume of loans, particularly to infrastructure and power sector borrowers, had been restructured and classified as performing despite serious underlying stress. The AQR forced banks to reclassify these loans as NPAs and make provisions against them, resulting in a dramatic surge in reported GNPA ratios and large losses across PSU banks between FY2016 and FY2019.

What were recapitalisation bonds and why were they issued?

Recapitalisation bonds were special government securities issued by the Government of India from FY2018 onward to inject equity capital into PSU banks whose capital adequacy ratios had fallen sharply due to large NPA provisions. The mechanism worked as follows: the government issued bonds which were subscribed to by the PSU banks themselves (using their excess SLR capacity or liquidity), and simultaneously received fresh equity shares in those banks worth the same amount. This allowed the government to inject capital without a direct cash outlay from the budget — though it increased the government's contingent liability. Over FY2018–FY2022, the government infused over ₹3.5 lakh crore in capital into PSU banks through various routes including recap bonds and direct budget provisions.

Why did 10 PSU banks merge into 4 in 2020?

The Government of India announced a major consolidation of PSU banks in August 2019, effective April 2020, reducing the number of nationalised banks from 18 to 12 (and the total PSU bank count from around 20 to under 15, including SBI which had already absorbed several associates). The primary motivations cited were: achieving scale to compete with large private banks, improving governance by concentrating management attention, reducing the capital subsidy burden on the government, and creating institutions large enough to fund large infrastructure projects. The key mergers included: Oriental Bank of Commerce and United Bank merging into Punjab National Bank; Syndicate Bank into Canara Bank; Allahabad Bank into Indian Bank; and Andhra Bank and Corporation Bank into Union Bank of India.

Why have PSU banks historically traded at lower P/B multiples than private banks?

PSU banks have historically traded at lower price-to-book (P/B) multiples than their private sector peers for several structural reasons. First, they have historically delivered lower return on equity (ROE) — constrained by government-directed lending, higher operating costs from large workforces, and more frequent large NPA cycles. Second, government ownership introduces uncertainty about capital allocation: dividends are sometimes paid not purely on commercial grounds but to meet government revenue targets. Third, management continuity is limited — top management typically serves fixed terms before rotation, making it harder to execute multi-year strategic plans consistently. Fourth, PSU banks historically had higher operating cost ratios due to legacy workforce structures governed by industry-wide wage settlements.

PSU Banks in India: Government-Owned Banking Explained | Sector Primer

What is a PSU bank?

A public sector undertaking (PSU) bankis a bank in which the Government of India owns more than 50% of the equity. As of 2025, there were 12 nationalised banks plus the State Bank of India (which is governed by a separate statute) in India's PSU banking system. Together they account for roughly 60% of total bank credit outstanding in India, making PSU banks the dominant channel through which formal credit reaches rural areas, small businesses, and lower-income borrowers.

The nationalisation of major Indian banks — first 14 in 1969 and then 6 more in 1980 — was driven by the political philosophy that the banking system should serve social objectives rather than purely commercial ones: directing credit to agriculture, small industries, and the economically weaker sections of the population. This legacy of social-mandate lending, and the governance structure that goes with majority government ownership, fundamentally distinguishes PSU banks from private sector banks in ways that show up in their financial metrics to this day.

The major players

India's PSU banking universe is anchored by a handful of large institutions:

State Bank of India (SBI) — the largest bank in India by assets, deposits, and branch network. SBI is not a nationalised bank in the strict legal sense (it operates under the State Bank of India Act, 1955) but is functionally a PSU bank with the government holding over 56%. SBI had assets exceeding ₹60 lakh crore and a branch network of over 22,000 branches as of recent reporting periods, making it significantly larger than any other Indian bank.
Bank of Baroda (BoB)— formed through the 2019 merger of Bank of Baroda, Vijaya Bank, and Dena Bank. It became India's third-largest bank by business volume.
Punjab National Bank (PNB) — the second-largest nationalised bank after SBI, expanded further by the 2020 merger with Oriental Bank of Commerce and United Bank of India.
Canara Bank — significantly enlarged by the 2020 merger with Syndicate Bank.
Union Bank of India — enlarged by the 2020 merger with Andhra Bank and Corporation Bank.
Indian Bank — absorbed Allahabad Bank in the 2020 merger round.

Beyond these, smaller PSU banks like Bank of India, Bank of Maharashtra, Central Bank of India, UCO Bank, and Indian Overseas Bank continue to operate independently.

The governance structure: how being government-owned shapes the bank

Government ownership above 50% has several specific implications for how a PSU bank is run, which are distinct from a private bank even if both face the same RBI regulations.

Management appointments: The chairman and managing director and key executive directors of PSU banks are appointed by the government through the Banks Board Bureau (BBB), which makes recommendations, subject to RBI approval. Management tenures are typically fixed (3–5 years) and followed by rotation. This is fundamentally different from a private bank where the board and promoters can retain high-performing leadership for decades — a continuity advantage that private banks have historically leveraged.

Directed lending and policy mandates: PSU banks are frequently asked to participate in government-sponsored schemes — Jan Dhan Yojana accounts, Kisan Credit Cards at subsidised rates, PM Mudra Yojana loans, MSME priority lending — that may not always generate commercial returns comparable to the risk taken. While these mandates serve important social goals, they can create drag on ROA and ROE relative to peers focused purely on credit-return optimization.

Dividend policy:Dividends paid by PSU banks are not just a capital allocation decision — they are a source of government revenue. The government as the majority shareholder receives dividends proportional to its stake, which means PSU banks occasionally pay dividends even when their capital ratios are not particularly comfortable, if the government's fiscal position requires the income.

The NPA crisis: 2015 to 2019

The most significant episode in recent PSU banking history was the non-performing asset (NPA) crisis that peaked between 2016 and 2018. To understand what happened, it is necessary to go back to the infrastructure and commodity lending boom of the mid-2000s.

Between roughly 2005 and 2012, PSU banks aggressively extended credit to large infrastructure projects — power plants, roads, ports, telecom — and to steel, real estate, and other capital-intensive businesses. Much of this lending was on the basis of optimistic project assumptions: power plants assumed favourable coal linkages and power purchase agreements that did not fully materialise; real estate projects assumed land values and sales velocities that proved excessive; telecom companies took on debt in a competitive frenzy that ended in consolidation.

As projects stalled and cash flows failed to materialise, borrowers sought restructuring of their loans. Banks, under regulatory frameworks that permitted restructuring as an alternative to NPA classification, restructured large amounts of stressed debt — keeping them on the books as "standard" loans. This masked the true scale of the problem.

The Asset Quality Review (AQR)

In the second half of 2015, the RBI under Governor Raghuram Rajan initiated the Asset Quality Review (AQR)— a systematic examination of the largest loan accounts across major banks. The AQR's purpose was to identify accounts that had been restructured but were functionally non-performing, and to require banks to reclassify and provision for them properly.

The results were stark. Over FY2016–FY2019, system-wide GNPA ratios — especially at PSU banks — rose dramatically. Several large PSU banks reported GNPA ratios exceeding 15% of their loan books. The provisioning required to cover these NPAs wiped out profitability for multiple consecutive years; several PSU banks reported net losses for three or four consecutive fiscal years.

The RBI also placed severely stressed banks under the Prompt Corrective Action (PCA) framework, which restricted their ability to expand lending, make large investments, or increase staff costs. At peak, 11 PSU banks were simultaneously under PCA restrictions.

Resolution: IBC and NCLT

Parallel to the AQR, the government enacted the Insolvency and Bankruptcy Code (IBC) in 2016— India's first modern insolvency resolution framework. IBC established National Company Law Tribunals (NCLTs) as the forum for insolvency proceedings and set a 180-day (extendable to 270-day) timeline for resolution. Before IBC, creditor resolution of large defaults could drag on for years or decades in the Debt Recovery Tribunals (DRTs) and courts.

The RBI directed banks to refer all accounts with exposures above ₹2,000 crore and classified as NPA to NCLT for resolution. This created the initial "Dirty Dozen" cases — 12 of the largest stressed accounts referred in mid-2017 — with total outstanding debt of approximately ₹2 lakh crore. Over the subsequent years, resolution plans were approved for several of these accounts (steel companies like Bhushan Steel and Essar Steel received significant haircuts but were acquired by stronger entities), while others resulted in liquidation.

Recapitalisation: how the government rebuilt the capital base

The provisioning required by the AQR and subsequent NPA recognition eroded the capital ratios of many PSU banks below comfortable levels. With their capital adequacy constrained, these banks were unable to grow their loan books — a vicious cycle where weak banks could not lend and the economy could not absorb the credit contraction.

The government's response was a large-scale recapitalisation programme announced in October 2017. The headline figure was ₹2.11 lakh crore to be infused into PSU banks over two years, through a combination of:

Recapitalisation bonds (recap bonds): special government securities issued directly to PSU banks. The banks subscribed to these bonds (booking them as investments) while simultaneously issuing fresh equity shares to the government. This was an accounting mechanism that injected Tier 1 capital without requiring a direct cash transfer from the Consolidated Fund of India.
Market-based capital raising: banks were encouraged to raise additional capital from the market via qualified institutional placements, which the government would participate in to maintain its majority stake.
Direct budgetary allocations: cash infusions from the Union Budget in subsequent years.

By FY2022, the government had cumulatively infused over ₹3.5 lakh crore into PSU banks across various tranches. This recapitalisation, combined with IBC resolutions and write-offs of fully provisioned NPAs, allowed most PSU banks to exit the PCA framework and resume normal operations by FY2020–21.

The merger wave of 2020: ten banks into four

Simultaneously with the recapitalisation, the government undertook the most significant consolidation in Indian banking history. In August 2019, Finance Minister Nirmala Sitharaman announced a series of mergers effective April 2020:

Punjab National Bank + Oriental Bank of Commerce + United Bank of India → creating the second-largest PSU bank
Canara Bank + Syndicate Bank → fourth-largest PSU bank
Union Bank of India + Andhra Bank + Corporation Bank → fifth-largest bank in India
Indian Bank + Allahabad Bank → seventh-largest PSU bank

These followed the earlier SBI merger of five associate banks and Bharatiya Mahila Bank into SBI in 2017. The government's stated rationale included creating institutions of sufficient scale to compete with large private banks globally, reducing the number of individual capital demands on the government, improving governance through fewer but larger boards, and enabling better technology investment amortisation.

Integration challenges were real: harmonising lending systems, HR policies, branch networks, and management cultures across banks with different histories took several years. Several merged entities reported elevated operating costs and transitional asset quality stress in the 24 months following merger.

The valuation question: why PSU banks trade at lower P/B

A persistent feature of Indian banking market analysis has been the significant valuation discount that PSU banks have historically traded at relative to high-quality private banks. Understanding this discount requires understanding what price-to-book (P/B) reflects.

P/B above 1x means the market values the bank at more than the book value of its equity — implying confidence that the bank will earn returns above its cost of equity and compound book value over time. P/B below 1x implies the market expects returns below the cost of equity — essentially that the bank will destroy value over time.

PSU banks have historically traded at P/B ratios well below the 1x–3x range commanded by top private banks. The structural reasons are several:

Lower ROE: a combination of higher operating costs (legacy workforce structures), government-directed lending at sub-optimal rates, and more frequent large NPA cycles has meant PSU banks have historically delivered lower ROE than private peers.
Management tenure constraints: fixed management terms make it difficult to execute multi-year strategic plans consistently, which reduces investor confidence in long-run value creation.
Capital uncertainty: since the government is the backstop for capital, PSU banks have a softer budget constraint — they can survive losses that would force a private bank to raise equity from the market at a steep discount. This is a safety net, but it also means poor capital allocation is less immediately punished.
Dividend leakage:as discussed, dividend payments to the government as controlling shareholder are not purely driven by capital adequacy comfort, which can constrain the bank's ability to reinvest earnings.

Post-IBC resolution and recapitalisation, PSU banks did see a partial re-rating — their P/B multiples expanded significantly from the crisis lows as asset quality improved and ROE recovered. However, the structural discount relative to the best private banks persisted in historical data.

Digital catch-up: YONO and the technology investment wave

SBI launched its flagship digital banking platform, YONO (You Only Need One), in 2017. YONO was an integrated banking and lifestyle app that allowed customers to open accounts, apply for loans, invest in mutual funds, and shop — all within a single application. By the early 2020s, YONO had accumulated tens of millions of registered users, making SBI's digital footprint one of the largest of any bank in India.

Other PSU banks also invested in digital transformation — mobile banking apps, UPI integration, digital account opening — though at varying speeds and quality levels. The gap in digital product quality between PSU and private banks, which was significant around 2015–17, had narrowed considerably by the early 2020s. However, the underlying technology stack of many PSU banks — built on older core banking systems — remained a challenge for the speed and scale of new feature development compared to more recently built private bank platforms.

Key metrics for PSU bank analysis

The core metrics for PSU banks are the same as for private banks (NIM, CASA ratio, GNPA, NNPA, PCR, slippage rate, ROA, ROE — all explained in detail in our private banks sector primer). However, several additional metrics are particularly relevant for PSU bank analysis:

Capital Adequacy Ratio (CAR) and CET1: Given the history of capital erosion during NPA cycles, monitoring CAR headroom above the regulatory minimum is important for assessing whether a PSU bank needs fresh equity (which would dilute minority shareholders or require government infusion).
Write-off rate: PSU banks historically wrote off NPAs at significant scale — removing fully provisioned bad loans from the balance sheet. While write-offs reduce reported GNPA ratios, they do not mean the debt is forgiven — banks continue recovery efforts. The write-off rate helps distinguish between genuine credit improvement and statistical improvement from write-offs.
Recovery from written-off accounts: cash recovered from accounts that were previously written off is a revenue line that tends to be lumpy and unpredictable, and should be separated from recurring operating profit for analytical purposes.
Dividend payout ratio: as discussed, PSU bank dividend decisions have a fiscal dimension. Tracking payout ratios vs. capital requirements is relevant for assessing equity dilution risk.
