Public Sector Undertakings (PSUs) are companies where the central or state government holds more than 50% of the equity. Also called Central Public Sector Enterprises (CPSEs) when owned by the central government, PSUs have been the backbone of India's industrialisation since independence. From steel and oil to banking and insurance, PSUs dominate strategic sectors. For UPSC, understanding PSU classification (Maharatna, Navratna, Miniratna), disinvestment policy, and the privatisation debate is essential.
What Are PSUs?
PSUs are government-owned corporations established to achieve specific economic and social objectives. They were created under the socialist-inspired Industrial Policy Resolutions of 1948 and 1956, which reserved key industries for the public sector.
The Department of Public Enterprises (DPE) under the Ministry of Finance oversees CPSEs. PSUs operate in sectors like petroleum, mining, power, steel, transport, telecommunications, banking, and defence production.
Why Were PSUs Created?
- Capital mobilisation: Private sector lacked resources for heavy industry
- Strategic control: Defence, nuclear energy, and key infrastructure
- Balanced regional development: Setting up industries in backward areas
- Employment generation: Job creation in the organised sector
- Import substitution: Reducing dependence on foreign goods
- Commanding heights of economy: Nehru's vision of state-led development
PSU Classification: Maharatna, Navratna, Miniratna
The government classifies CPSEs based on their financial performance and strategic importance, granting higher-tier companies greater operational autonomy.
Maharatna Status
The highest tier. Maharatna CPSEs can invest up to Rs 5,000 crore or 15% of net worth in a single project without government approval.
Criteria:
- Must already be a Navratna
- Average annual turnover > Rs 25,000 crore (3 years)
- Average annual net worth > Rs 15,000 crore (3 years)
- Average annual net profit > Rs 5,000 crore (3 years)
- Listed on Indian stock exchange
Current Maharatnas (as of 2024): ONGC, Indian Oil Corporation (IOC), NTPC, Coal India, Steel Authority of India (SAIL), Bharat Petroleum (BPCL), Hindustan Petroleum (HPCL), GAIL, Power Grid Corporation, Oil India, NHPC, Power Finance Corporation (PFC), REC Limited, Indian Railway Finance Corporation (IRFC).
Navratna Status
Navratna CPSEs can invest up to Rs 1,000 crore or 15% of net worth in a single project.
Criteria:
- Must be a Miniratna-I or Schedule 'A' CPSE
- Score 60+ on six performance parameters (net profit, net worth, turnover, cost of production, manpower cost, PBDIT)
- Must have 'Excellent' or 'Very Good' MoU rating for 3 of the last 5 years
Examples: Bharat Electronics Limited (BEL), Hindustan Aeronautics Limited (HAL), NMDC, NBCC, NLC India.
Miniratna Status
Miniratna Category-I: Must have earned profit in the last 3 years and positive net worth. Can invest up to Rs 500 crore or net worth, whichever is lower.
Miniratna Category-II: Must have earned profit for the last 3 years and positive net worth. Can invest up to Rs 300 crore or 50% of net worth.
PSU Classification Comparison
| Parameter | Maharatna | Navratna | Miniratna-I | Miniratna-II |
|---|---|---|---|---|
| Investment limit | Rs 5,000 cr or 15% NW | Rs 1,000 cr or 15% NW | Rs 500 cr or NW | Rs 300 cr or 50% NW |
| Turnover requirement | > Rs 25,000 cr | Performance-based scoring | Profit for 3 years | Profit for 3 years |
| Net profit requirement | > Rs 5,000 cr | Performance scoring | Positive net worth | Positive net worth |
| Operational autonomy | Highest | High | Moderate | Limited |
Role of PSUs in Indian Economy
PSUs play a significant role across multiple dimensions:
Economic Contribution
- CPSEs contribute roughly 12% of GDP
- They generate significant employment — over 15 lakh direct employees
- PSU banks hold about 60% of banking assets
- Oil PSUs (ONGC, IOC, BPCL, HPCL) dominate the energy sector
- Coal India produces over 80% of India's coal
Strategic Sectors
PSUs maintain government control in strategic areas:
- Defence: HAL, BEL, Bharat Dynamics, BEML
- Nuclear energy: Nuclear Power Corporation of India Ltd (NPCIL)
- Space: Indian Space Research Organisation (commercial arm: NewSpace India Ltd)
- Railways: Indian Railways, IRCTC, IRFC
- Mining: Coal India, NMDC
Dividend and Revenue
CPSEs pay dividends to the government — a significant source of non-tax revenue. The government also earns from disinvestment of CPSE equity. In recent years, the government has increasingly relied on PSU dividends and disinvestment proceeds to meet fiscal targets.
Disinvestment and Privatisation
Disinvestment
Disinvestment means reducing the government's equity stake in PSUs. It can be:
- Minority disinvestment: Government sells shares but retains majority (>51%) ownership
- Strategic disinvestment: Government sells majority stake along with management control to a strategic buyer
- OFS (Offer for Sale): Government sells shares through stock exchange
Key Disinvestment Episodes
The Disinvestment Commission under GV Ramakrishna (1996) recommended strategic sale of non-strategic PSUs. The Atal Bihari Vajpayee government (1999–2004) was the most aggressive in strategic disinvestment — selling majority stakes in BALCO, Hindustan Zinc, IPCL, and VSNL.
The Department of Investment and Public Asset Management (DIPAM) manages disinvestment policy.
New Public Sector Enterprise Policy (2021)
The government announced a comprehensive policy classifying sectors as:
Strategic sectors (where at least one CPSE will remain): Atomic energy/space/defence; transport and telecommunications; power/petroleum/coal/minerals; banking/insurance/financial services.
Non-strategic sectors: All other sectors — government will either privatise, merge, or close loss-making CPSEs.
This represented a fundamental shift — acknowledging that the government need not be in every business.
Notable Strategic Disinvestments
- Air India (sold to Tata Group in 2022): Ended decades of losses — the most prominent privatisation
- BPCL: Planned strategic sale (pending)
- Life Insurance Corporation (LIC): IPO in 2022 — largest IPO in Indian history at the time

Challenges Facing PSUs
Inefficiency and Bureaucracy
PSUs often suffer from bureaucratic decision-making, political interference in appointments, and lack of commercial orientation. Pay scales don't match private sector for senior talent, leading to brain drain.
Loss-Making PSUs
Several CPSEs have accumulated massive losses. Sick PSUs drain government resources and occupy scarce land and assets that could be more productively used. The Board for Reconstruction of Public Sector Enterprises (BRPSE) reviews sick units.
Competition from Private Sector
After liberalisation, PSUs face competition from efficient private companies and multinationals. In sectors like telecom (BSNL/MTNL vs private operators) and aviation (Air India vs IndiGo), PSUs have lost market share dramatically.
Governance Issues
- Lack of professional boards — government appointees dominate
- Delayed appointments of CMDs (Chief Managing Directors)
- Multiple layers of scrutiny (CVC, CAG, CBI) create decision paralysis
- Commercial decisions get entangled with political considerations
| Challenge | Example | Reform Attempted |
|---|---|---|
| Losses | BSNL, MTNL, Air India | Merger (BSNL-MTNL), privatisation (Air India) |
| Governance | Delayed CMD appointments | Banks Board Bureau (for bank PSUs) |
| Competition | Telecom, aviation | Strategic disinvestment |
| Overstaffing | Coal India, railways | VRS schemes |
PSU Reforms
Corporatisation
Converting departmental undertakings into companies — giving them more autonomy. Indian Railways has created separate companies for specific functions (IRCTC for catering/tourism, IRFC for financing).
Listing on Stock Exchanges
Listing PSU shares improves transparency, governance, and market discipline. SEBI's minimum public shareholding norms require listed companies to have at least 25% public float.
Performance Monitoring
The DPE uses Memorandum of Understanding (MoU) system — CPSEs sign annual performance agreements with the government. Performance is rated as Excellent, Very Good, Good, Fair, or Poor.

Frequently Asked Questions
What is the difference between Maharatna and Navratna PSUs?
Maharatna PSUs have the highest operational autonomy — they can invest up to Rs 5,000 crore in a single project without government approval. Navratna PSUs can invest up to Rs 1,000 crore. Maharatna status requires being a Navratna first, plus meeting additional thresholds for turnover (Rs 25,000 crore), net worth (Rs 15,000 crore), and net profit (Rs 5,000 crore).
What is strategic disinvestment?
Strategic disinvestment means the government sells its majority stake (along with management control) in a PSU to a private buyer. Unlike minority disinvestment where the government retains control, strategic disinvestment transfers ownership. The sale of Air India to Tata Group in 2022 is the most prominent recent example. It is managed by the Department of Investment and Public Asset Management (DIPAM).
Why were PSUs created in India?
PSUs were created because the private sector lacked capital for heavy industrialisation, and the government wanted to control strategic industries, generate employment, ensure balanced regional development, and achieve self-reliance through import substitution. The Industrial Policy Resolutions of 1948 and 1956 provided the policy framework, reserving key sectors exclusively for the public sector.
What is the New Public Sector Enterprise Policy?
Announced in 2021, this policy classifies all sectors as "strategic" or "non-strategic." In strategic sectors (defence, energy, banking, transport), at least one PSU will be retained. In non-strategic sectors, PSUs will be privatised, merged, or closed. This marked a significant shift from the earlier approach of maintaining a large public sector footprint across the economy.
