Part of the Financial Services sector
Industry Overview
India's public sector banks (PSBs) control ₹90+ lakh crore in deposits — still the largest chunk of the banking system (~55% share). After the massive NPA cycle of 2015-2020 and consolidation from 27 PSBs to 12, the sector has emerged cleaner, better-capitalised, and more profitable than at any point in the last decade.
Key players
| Company | Market Position | Strength | Total Business |
|---|---|---|---|
| SBI | India's largest bank | Unmatched scale, 22,000+ branches | ₹75+ lakh Cr |
| Bank of Baroda | 2nd largest PSB (post-merger) | International + technology | ₹20+ lakh Cr |
| PNB | 3rd largest PSB (post-merger) | North India dominance | ₹20+ lakh Cr |
| Canara Bank | 4th largest PSB | South India + technology | ₹18+ lakh Cr |
| Union Bank | 5th largest PSB | SME focus, integration complete | ₹16+ lakh Cr |
Why this industry matters
- PSBs still handle 55% of India's credit — system-critical
- Post-NPA resolution, PSB profitability at 15-year highs (ROA 0.8-1.0%)
- Valuation discount to private banks (0.8-1.5x P/B vs 2-4x) creates asymmetric opportunity
- Government ownership (> 50%) drives policy lending + financial inclusion mandates
What you will learn
- Industry Overview: PSB business model, government mandates, and post-consolidation landscape
- Key Metrics: NIM, GNPA, PCR, ROA, CRAR, and slippage ratio
- Competitive Landscape: PSB vs private bank dynamics, scale advantages
- Risks: Political interference, governance, and cyclicality
- Valuation: P/B discount framework and catalyst identification

1. Public Sector Bank — Industry Overview
Public Sector Bank (Financial Services sector)
What you will learn
How PSBs operate, why government ownership creates both advantages and constraints, and the post-consolidation structural improvements.
The business model
PSBs earn from the same NII model as private banks, but with key structural differences:
PSB Revenue = NII (lower NIM) + Fee Income (underdeveloped) + Treasury Gains (higher share)
Key differences from private banks
| Parameter | PSBs | Private Banks |
|---|---|---|
| Ownership | Government > 50% | Promoter/institutional |
| NIM | 2.5-3.2% | 3.5-5.0% |
| CASA ratio | 40-45% | 38-55% |
| Cost-to-income | 50-60% | 40-50% |
| Fee income share | 10-15% | 15-22% |
| Technology spend | Catching up | Leading |
| Branch network | 85,000+ combined | 40,000+ |
| Rural reach | Unmatched (70% rural/semi-urban) | Urban-focused |
The consolidation story (2019-2021)
| Merger | Result | Rationale |
|---|---|---|
| Dena + Vijaya + BoB | Bank of Baroda | Scale + technology synergy |
| OBC + UBI + PNB | Punjab National Bank | North India consolidation |
| Andhra + Corp + Union | Union Bank of India | Balance sheet strength |
| Syndicate + Canara | Canara Bank | South India scale |
| Allahabad + Indian | Indian Bank | Regional complementarity |
Result: 27 PSBs → 12 PSBs. Cleaner, larger, better capitalized.
Government mandates — the dual role
PSBs serve both commercial and social objectives:
| Mandate | Commercial Impact |
|---|---|
| Priority Sector Lending (40%) | Forced allocation to agriculture, SME at thin margins |
| Financial inclusion (Jan Dhan) | 50 Cr+ zero-balance accounts — operational cost |
| Government schemes (MUDRA, PM SVANidhi) | Directed lending with subsidy dependencies |
| Rural branch mandate | 25% of new branches in unbanked areas |
| Wage bill (bipartite settlements) | Higher employee costs, limited flexibility |
🗣️
"PSU banks ka problem banking nahi hai — governance hai. Jab tak sarkaar majority owner hai, commercial decisions political pressure ke under hongi."
Growth drivers (post-2021 recovery)
- Clean balance sheets: GNPA from 14%+ (FY18) → 3-5% (FY25) — best in 10 years
- Adequate capital: CRAR > 14% for most PSBs (vs 10.5% RBI minimum)
- Digital catch-up: YONO (SBI), BoB World — improving technology
- Credit cycle tailwind: Corporate capex revival benefits PSBs' corporate books
- Valuation re-rating: P/B from 0.3x (FY20) → 0.8-1.5x (FY25)
✅ Checklist
- ○I understand PSBs earn lower NIMs due to higher cost-to-income and PSL mandates
- ○I know the consolidation reduced PSBs from 27 to 12 (stronger, larger entities)
- ○I recognize the dual mandate (commercial + social) creates structural handicaps
- ○I see the current cycle as the cleanest PSB balance sheets in a decade
Key takeaway
PSBs operate the same banking model as private banks but with structural constraints — government ownership, PSL mandates, higher costs, and lower NIMs. Post-consolidation and NPA resolution, PSBs are at their healthiest in 15 years, trading at significant valuation discounts to private peers.
