For decades after Independence, the Indian state built and owned steel plants, banks, airlines, oil companies and power utilities, which together formed the public sector. From 1991, as the country opened its economy, the government began to reduce its ownership in many of these firms. This process of selling part or all of the government’s equity in public sector undertakings is known as disinvestment in India. It has been used to raise resources, widen share ownership, improve efficiency and, in recent years, to reshape the role of the state in business.
Disinvestment is a technical-sounding term that covers a wide spectrum, from selling a small slice of shares on the stock market to handing over management control to a private buyer. This explainer sets out the meaning and objectives of disinvestment, the institutions that manage it, the methods used, the landmark transactions such as Air India’s sale to the Tata group, the BPCL process and the LIC IPO, and the main arguments on both sides of the debate.

What Is Disinvestment?
Disinvestment means that the government reduces its shareholding in a public sector enterprise. When the government owns shares in a company, whether it is a central public sector enterprise (CPSE) or a bank or insurer, it can sell some or all of them to the public, to institutions or to a chosen buyer. The money raised goes to the government, although how it is used has varied over the years.
Disinvestment is different from nationalisation, which brings private assets under public ownership, and from simple privatisation as commonly understood. In many cases, disinvestment does not change control at all. If the government sells a few per cent of its stake and still holds more than half the shares, the company remains a government company. Only when control moves to a private party, either through the sale of a majority stake or by giving management control, does the process amount to privatisation.
Disinvestment and privatisation
- Minority disinvestment: The government sells a part of its stake and retains majority ownership and control.
- Strategic disinvestment: The government sells a significant stake, often along with management control, to a strategic buyer.
- Privatisation: A complete or majority transfer of ownership and control from the state to the private sector.
Why India Turned to Disinvestment
The shift began in the economic crisis of 1991. Public sector undertakings had been established to occupy the commanding heights of the economy, but many of them were weighed down by low returns, overstaffing, political interference and heavy dependence on budgetary support. At the same time, the government faced a severe fiscal and balance-of-payments squeeze and needed both resources and efficiency.
The reform programme of 1991 therefore included a call to open up public sector areas, to reform loss-making units and to sell a part of the government’s holdings in profitable ones. The policy had several stated aims.
- Raising non-tax revenue to reduce the burden on the fiscal deficit.
- Broadening and deepening the equity market through wider public ownership.
- Improving performance through market discipline and accountability to shareholders.
- Letting the government focus on core functions such as health, education, infrastructure and security.
- Giving employees and small investors a stake in public enterprises.
Evolution of the Disinvestment Policy
The disinvestment policy has gone through a number of phases, from cautious beginnings to bold strategic transactions and, later, a clear policy on which sectors the state should stay in.
The early phase, 1991 to 1999
In the first phase, the government sold small minority stakes through bundles of shares auctioned to financial institutions. The Rangarajan Committee reviewed the approach in the early 1990s and favoured a gradual route. A Disinvestment Commission was set up in 1996 to advise on the extent and method of disinvestment. Progress was slow, and the programme was frequently questioned for the pricing and for the use of the proceeds.
The strategic sale phase, 1999 to 2004
A dedicated Department of Disinvestment was created in 1999, which became a full Ministry of Disinvestment in 2001. This period saw strategic sales in which management control passed to private buyers. Modern Foods was among the first. Others included BALCO, which was sold to Sterlite, and VSNL, which went to the Tata group. The Supreme Court, in a case relating to BALCO, upheld the government’s authority to make such policy decisions, while stressing the importance of transparency.
The minority sale phase, 2004 onwards
After 2004, the approach moved back towards selling minority stakes while retaining control, and the disinvestment function was placed under the Finance Ministry as a department. In 2016 it was renamed the Department of Investment and Public Asset Management, reflecting a broader remit that covers management of the government’s investments and public assets and not only sales.
Institutions Involved: DIPAM and Related Bodies
Disinvestment is managed by the Department of Investment and Public Asset Management (DIPAM), which functions under the Ministry of Finance. DIPAM advises on investment of the government in CPSEs, handles capital restructuring, oversees sale transactions and sets out the broad policy on disinvestment of public assets.
Major transactions are decided through a structured process. Proposals for strategic sale are considered by an inter-ministerial group, and the final decisions are taken by the Cabinet or a committee of Ministers constituted for the purpose. Transaction advisers, legal advisers and asset valuers are appointed through competitive selection, and the reserve price is determined through formal valuation.
Key participants
- Cabinet or a committee of Ministers: Approves the policy decision and the final deal.
- Alternative Mechanism: A ministerial group that oversees the decision on method and price in major strategic sales.
- Administrative ministry: The ministry in charge of the enterprise, which is consulted on the sector implications.
- SEBI and stock exchanges: Regulate and execute market-based sales for listed companies.
Methods of Disinvestment
The government uses several routes depending on the objective, the market conditions and whether it wishes to retain control.
| Method | How it works | Typical use |
|---|---|---|
| Initial Public Offer (IPO) | An unlisted public enterprise lists on stock exchanges by offering shares to the public | First-time listing, for example of a large unlisted company |
| Follow-on Public Offer (FPO) | A listed company issues additional shares or the government sells more of its stake | Further sales in listed firms |
| Offer for Sale (OFS) | Promoter sells shares through a transparent exchange-based auction window | Quick and cost-effective minority stake sales |
| CPSE ETF | An exchange-traded fund holding shares of several CPSEs is offered to investors | Diversified sale of minority stakes to retail and institutions |
| Strategic sale | Stake and management control are transferred to a chosen buyer through competitive bidding | Privatisation of selected enterprises |
| Buyback and delisting | The company repurchases shares or is taken off the exchanges | Returning surplus cash or exiting the market |
The offer for sale route through stock exchanges was introduced in 2012 and became the workhorse of minority disinvestment. CPSE exchange-traded funds, launched from 2014 and followed by the Bharat 22 ETF in 2017, were designed to give retail investors easy access to a basket of public sector stocks.
Minority Stake Sales: Raising Funds Without Losing Control
Minority disinvestment has been the most common form of share sale in India. The government sells a portion of its stake in a listed or soon-to-be-listed PSU, but remains the largest shareholder and keeps control. Companies such as Coal India, whose public offer in 2010 was among the largest in India at that time, are examples. Later offers included IRCTC and Mazagon Dock, which listed in 2019 and 2020 respectively.
Listed companies must also meet the minimum public shareholding norm set by SEBI, under which at least 25 per cent of shares must be in public hands. Disinvestment in many PSUs has therefore been needed even to meet these listing requirements.
Advantages of the minority route
- It improves transparency, since listed companies disclose results and are monitored by analysts and regulators.
- It brings market-based price discovery of the value of the enterprise.
- It is politically easier than a change of control because employees and public ownership interests are preserved.
- It lets the government unlock value without surrendering strategic influence.
Strategic Disinvestment and Privatisation
Strategic disinvestment goes much further than a share sale. The government transfers a controlling stake, together with management control, to a chosen private buyer, usually through a competitive bidding process. This is regarded as the true form of privatisation, and it is meant to bring in new capital, technology and management expertise.
The Public Sector Enterprise policy of 2021, announced as part of the Atmanirbhar Bharat package, set out a clear framework. It identified a limited list of strategic sectors, in which a minimal presence of public enterprises would be maintained, and indicated that enterprises in other sectors would be considered for privatisation or other forms of exit. Sectors such as atomic energy, space and defence were in the strategic category, while banking, insurance and financial services were also identified as areas where a minimum public presence would be retained.
Related approaches
- Asset monetisation: Instead of selling an enterprise, the government leases or licenses its assets such as roads, pipelines or airports to private operators for a period. The National Monetisation Pipeline announced in 2021 followed this idea.
- Closure and merger: Loss-making or redundant enterprises may be closed, merged or restructured.
- Cross-holding transactions: One PSU may buy the government’s stake in another, as when a major oil company acquired the government’s stake in a refiner in 2018.
Landmark Case: Air India Goes Back to the Tata Group
Air India has one of the most storied histories in Indian business. The airline began as Tata Airlines in 1932 under J. R. D. Tata. The government took a substantial stake in 1948 in the joint venture Air India International, and the airline was nationalised in 1953 under the Air Corporations Act. For decades it operated as a national flag carrier, but over time it accumulated heavy losses and debt.
Attempts to sell it started earlier in the 2000s and 2010s, but failed to attract enough interest. A fresh process was launched in 2020, and in October 2021 the government accepted a bid from Talace Private Limited, a subsidiary of Tata Sons. The transfer was completed in January 2022, with the buyer taking over management control and a substantial part of the airline’s debt. The deal also included the low-cost carrier Air India Express and a ground handling joint venture. Because it brought the airline back to its original founders, it is often cited as a symbolically powerful case of strategic disinvestment.
Landmark Case: The BPCL Process
Bharat Petroleum Corporation Limited (BPCL) is one of the largest public sector oil marketing and refining companies. In 2019 the government approved the sale of its entire stake of more than half the company’s shares, in what would have been the largest strategic sale in India’s history. Management control was to be transferred to a private buyer, and the process drew initial expressions of interest from multiple players.
However, as the process moved forward, several of the interested bidders withdrew, citing reasons connected with global energy transition and market volatility. The government eventually decided in 2022 to defer or call off the process, since conditions were not suitable. The BPCL case is frequently studied as an example of how external factors, such as energy markets and the sector’s long-term outlook, can derail even a well-planned strategic sale.
Landmark Case: The LIC IPO
The Life Insurance Corporation of India (LIC) was formed in 1956 through nationalisation of life insurance. It is India’s largest life insurer and one of the biggest institutional investors in the country. To allow its listing, Parliament amended the Life Insurance Corporation Act through the Finance Act of 2021 and the structure of the corporation was adapted for a share issue.
The LIC initial public offer opened in May 2022 and was the largest IPO in India’s history at that time. The government sold a small fraction of its holding, a few per cent, retaining overwhelming ownership and control. A portion of the issue was reserved for policyholders and employees. The listing was notable because it was a minority disinvestment of an enormous institution and brought millions of new small investors into the market, though the shares traded below the issue price in the initial period.
Arguments in Favour of Disinvestment
- Fiscal support: Proceeds can be used for infrastructure and social spending without additional taxation or borrowing.
- Efficiency gains: Private management and market discipline can improve productivity, technology and customer service.
- Focus of the state: The government can concentrate on regulation and public goods instead of running commercial businesses.
- Capital market deepening: Listings add depth to the market and offer investors new opportunities.
- Relief from losses: Chronic loss-makers drain public resources that could be used elsewhere.
- Accountability: Shareholders, analysts and regulators scrutinise listed companies more closely than administrative ministries do.
Arguments Against and Criticisms
- Selling the family silver: Critics argue that selling assets for current needs sacrifices long-term revenue and strategic assets, since profitable PSUs pay regular dividends.
- Valuation and transparency: There are concerns that assets may be sold too cheaply or through opaque processes, particularly in strategic sales.
- Employment and social objectives: Public sector firms have historically provided stable jobs, reservations and regional development, and their privatisation may affect these goals.
- Private monopoly risk: Transferring a public monopoly to a private buyer may simply replace one monopoly with another without competition.
- Strategic security: Enterprises in energy, defence and critical infrastructure may have a national security dimension.
- Revenue targets: Targets announced in Budgets have often been missed, which can create fiscal uncertainty.
Supporters reply that the real test is the quality of the process, namely competitive bidding, independent valuation, regulatory safeguards and protection of workers, and that disinvestment should be judged on outcomes and not on ideology.
Conclusion
Disinvestment has been part of India’s economic policy for over three decades. It has ranged from small share sales in the early 1990s to strategic privatisation in the early 2000s, to the high-profile transactions of the 2020s. The central institution, DIPAM, uses a toolkit of methods that includes OFS, ETFs, public offers, strategic sales and asset monetisation. Air India’s return to the Tata group, the lapsed BPCL process and the LIC IPO show both the potential and the difficulties of the policy. As India continues to define the proper size and role of its public sector, disinvestment will remain a major topic in economic debate.
Frequently Asked Questions
What is disinvestment in India?
Disinvestment is the sale or dilution of the government’s shareholding in public sector enterprises. It can be a minority stake sale, in which the government retains control, or a strategic sale in which management control passes to a private buyer.
Which department handles disinvestment?
The Department of Investment and Public Asset Management, or DIPAM, in the Ministry of Finance manages disinvestment. It was earlier known as the Department of Disinvestment, a Ministry of Disinvestment, and later a department of the Finance Ministry before being renamed DIPAM in 2016.
What is the difference between disinvestment and privatisation?
Disinvestment is the broader term covering any reduction in government equity, even when the government remains the majority owner. Privatisation means a transfer of ownership and control to the private sector, which happens only when a controlling stake is sold.
How was Air India sold?
The government invited bids for the airline and in October 2021 accepted the offer from Talace Private Limited, a subsidiary of Tata Sons. The handover took place in January 2022, bringing the airline back to the group that founded it in 1932.
What happened to the BPCL privatisation?
The government approved the sale of its entire stake in Bharat Petroleum in 2019 and began a bidding process. After several interested bidders withdrew, the government decided in 2022 not to proceed with the sale at that time.
What is an Offer for Sale (OFS)?
An Offer for Sale is a method in which a promoter, including the government, sells shares of a listed company through a special trading window on the stock exchange. It is transparent, quick and cost-effective, and has been widely used for minority disinvestment since 2012.
