Short answer: Foreign direct investment, or FDI, is cross-border investment (money that crosses a national border) in which an investor based in one country acquires significant, ongoing influence over a business located in another country. The investor is not just a passive holder of shares; it is an active owner that takes part in how the foreign business is run.

How is FDI different from portfolio investment?
Foreign portfolio investment means holding a foreign company’s securities (shares or bonds) without taking part in running it. The difference is intent and involvement. FDI involves a lasting interest and active management of the foreign business, while portfolio investment is passive holding.
This distinction matters because the two behave differently. A passive holder can usually sell its shares without affecting the business. An investor with active management is tied to the business’s direction, its people and its results.
How does FDI actually get made?
FDI can be carried out in three main ways. The first is a merger or acquisition, where an investor buys a foreign business or combines with one. The second is a collaboration with a foreign firm, where two companies work together on a shared venture. The third is setting up a subsidiary abroad, which is a business unit the investor creates and controls in another country.
Each route gives the investor a different starting point. Buying an existing business gives immediate operations and customers, while building a subsidiary means the investor starts from scratch in the new market. Collaboration sits between the two, with the investor sharing both work and decisions with a partner.
What are the main types of FDI?
FDI is also classified by the relationship between the investor’s business and the foreign one. Horizontal FDI happens when a company invests abroad in a business in the same sector as its own, producing similar goods or services. A car maker buying a rival car maker in another country is a simple example.
Vertical FDI involves investing in a foreign supplier or another link in a supply chain, rather than in a business making the same product. Conglomerate FDI involves investing in a foreign business in an entirely different sector from the investor’s own. Platform FDI involves manufacturing abroad to export the output to a third country, so the factory’s goods are sold outside both the investor’s home country and the host country.
What does FDI bring besides money?
Because FDI is non-debt capital, meaning it is equity-type money and not a loan, the foreign business does not take on a borrowing obligation to repay it. The investor also brings technology, management expertise and know-how. For a business in India receiving FDI, these can matter as much as the cash.
The catch is that these benefits are not automatic. Know-how moves only if the investor actually shares it and the local business absorbs it. A transfer of technology is something that has to be worked at, not something that arrives with the money.
What is a worked example?
The following is a hypothetical example with invented figures, not a real transaction. Suppose a foreign company buys a 51% stake in an Indian business that is valued at ₹50 crore. The foreign company pays 51% of ₹50 crore, which is ₹25.5 crore, or 2,550 lakh, since 1 crore equals 100 lakh.
Now suppose the business later falls in value to ₹30 crore. The foreign company’s 51% stake is then worth ₹15.3 crore, so its paper loss is ₹10.2 crore. The example shows that an FDI investor carries the business’s ups and downs in proportion to its stake.
What are the catches with FDI?
The first catch is that the money is tied up. A stake in a business that is not traded on a public market can take longer to sell than shares that trade every day. The investor has to plan for a long holding period.
The second catch is control and distance. Decisions about a business in India may be made by managers in another country, who may not know the local market well. A third catch is that a foreign investor may buy a business in a sector it does not understand, as with conglomerate FDI. Without expertise in that sector, the investor may struggle to add value.
Frequently asked questions
Is FDI the same as buying shares on a stock exchange?
No. FDI involves a lasting interest and active management of the foreign business. Buying shares without taking part in running the company is foreign portfolio investment.
Does FDI involve borrowing?
FDI is non-debt capital, so the money it brings is not a loan. It also brings technology, management expertise and know-how.
Can FDI happen without buying an existing business?
Yes. FDI can take the form of a collaboration with a foreign firm or the setting up of a subsidiary abroad.
What is platform FDI?
Platform FDI involves manufacturing abroad to export the output to a third country. The factory’s goods are sold in a country other than the investor’s home and the host country.
