GATS and the Four Modes of Trade in Services

The General Agreement on Trade in Services, or GATS, is the World Trade Organization's (WTO) rulebook for trade in services. Services are things you cannot drop on your foot: banking, software, teaching, tourism, health care, transport. GATS says there are four ways (called modes) in which a service can cross a border. It also sets rules on how countries open their service markets to foreign suppliers.

Why does it exist?

For a long time, world trade rules covered only goods, through the General Agreement on Tariffs and Trade (GATT) of 1947. But services were becoming a huge part of every economy. Countries blocked foreign service providers in many ways: banning foreign banks, capping foreign shares in insurance, or refusing visas to foreign professionals. There was no common rulebook. GATS was created to bring services under clear, predictable, shared rules, just as GATT did for goods.

Where did it come from?

• Services were brought into the trade talks during the Uruguay Round (1986 to 1994), the round of talks that created the WTO.
• GATS was signed in 1994 at Marrakesh as part of the WTO Agreement. It is Annex 1B of that agreement (GATT is in Annex 1A, and TRIPS, on intellectual property, is Annex 1C).
• It came into force on 1 January 1995, the same day the WTO was born.
• Article XIX of GATS promised new rounds of talks to open services further, starting within five years. These talks began in January 2000 and were later folded into the wider Doha Development Agenda (launched 2001).

What are the four modes?

Article I:2 of GATS defines trade in services through four modes. A simple way to remember them is to ask: who or what is moving?

1. Mode 1: Cross-border supply. Only the service moves. The supplier and the customer both stay at home. Example: an Indian IT company in Bengaluru writes software for a bank in London and sends it online.
2. Mode 2: Consumption abroad. The customer moves to the supplier's country. Example: a UK tourist visits Kerala, or a patient from Africa comes to Chennai for surgery, or an Indian student studies at a UK university.
3. Mode 3: Commercial presence. The supplier sets up a business (a branch or a company) in the customer's country. Example: a UK bank opens branches in India, or an Indian IT firm opens an office in the UK.
4. Mode 4: Presence of natural persons. A person (a "natural person", meaning a human being, not a company) travels to the other country for a short time to supply the service. Example: an Indian software engineer, chef or yoga teacher goes to the UK on a temporary work visa.

Which modes are biggest?

As per WTO estimates in the World Trade Report 2019 (for the year 2017), world services trade was worth about US$13.3 trillion. Its split was roughly:

• Mode 3 (commercial presence): 58.9%, the largest
• Mode 1 (cross-border supply): about 27.7%
• Mode 2 (consumption abroad): about 10.4%
• Mode 4 (movement of persons): about 2.9%, the smallest

So Mode 4 is tiny in world trade. This is partly because rich countries keep tight limits on visas for foreign workers.

What does GATS cover, and what not?

• GATS covers all services, in all sectors, except services supplied "in the exercise of governmental authority" (Article I:3). These are services the government gives neither on a commercial basis nor in competition with private suppliers, like the police or a central bank's core work.
• The WTO uses a services list (document W/120) that divides services into 12 sectors: business, communication, construction and engineering, distribution, education, environment, financial, health, tourism and travel, recreation/cultural/sporting, transport, and "other".
• The Annex on Movement of Natural Persons makes it clear that Mode 4 is about temporary stay only. GATS does not cover people looking for jobs in another country's job market, and it does not cover citizenship, permanent residence or permanent jobs. Each country also keeps the right to control entry and temporary stay through its visa rules, as long as this does not cancel the commitments it has made.

How do the rules work? Two layers

GATS works in two layers. Think of it as "rules for everyone" plus "promises each country chooses".

Layer 1: General obligations (apply to all services):

• Most Favoured Nation (MFN), Article II: a country must treat service suppliers from all WTO members equally. If India lets in a bank from one country, it cannot block a bank from another member on the basis of nationality. Countries could list one-time exceptions (MFN exemptions) when GATS began.
• Transparency, Article III: countries must publish their rules affecting services trade.

Layer 2: Specific commitments (apply only where a country chooses to open up):

• Market access, Article XVI: in a sector it has opened, a country cannot use six kinds of limits unless it has written them in its schedule: limits on (1) the number of suppliers, (2) the total value of transactions or assets, (3) the number of operations or amount of output, (4) the number of people who may be employed, (5) the type of legal entity or joint venture, and (6) foreign capital (for example, a cap on foreign shareholding).
• National treatment, Article XVII: in a sector it has opened, a country must treat foreign suppliers no worse than its own domestic suppliers, unless it has written a limit in its schedule.

Each country files a schedule of specific commitments. For each sector and each of the four modes, it writes what it allows. "None" means no limits (fully open). "Unbound" means no promise at all (the country is free to restrict). This way, a country can open Mode 1 in software fully but keep Mode 4 unbound. Because a country chooses which sectors to list, this is called a positive list approach.

Services in free trade agreements

Article V of GATS allows countries to sign deeper services deals with some partners, as an exception to MFN. Such a deal must have "substantial sectoral coverage" (judged by the number of sectors, the volume of trade and the modes covered). Promises in an FTA that go beyond a country's GATS schedule are called "GATS-plus" commitments. Many of India's recent FTAs, like those with the UAE, Australia, EFTA and the UK, have services chapters built on the four modes.

India's position and Indian examples

• Services make up more than half of India's economy. India's services exports rose to about US$421.3 billion in 2025-26, from about US$387.5 billion in 2024-25, as per government data shared in Parliament. Telecom, computer and information services were the largest part.
• As per the WTO, India ranked 8th in world commercial services exports in 2024, with a 4.3% share (about US$374 billion), and 5th in digitally delivered services, with a 5.8% share. India's share was about 2% in 2005.
• India's strength is Mode 1 (IT and business services sent online) and Mode 4 (skilled professionals). As per the RBI, India's software services exports were about US$221.4 billion in 2025-26, and 91.7% of them were delivered "off-site", that is, from India (Mode 1).
• So in trade talks, India pushes hard for easier visas for professionals (Mode 4) and for treating Indian IT services fairly (Mode 1). Richer countries usually push for opening of Mode 3 in banking, insurance, retail and legal services.
• India also signs social security agreements, such as the India-UK Double Contribution Convention, so that Indian professionals on short postings abroad do not pay social security twice. This makes Mode 4 cheaper and more attractive.
• India, along with South Africa, has objected to some WTO "joint statement initiatives" (plurilateral talks among a group of members, not all), including one on services domestic regulation. India argues that such talks were never given a mandate by all WTO members and go against the WTO's consensus-based system.

Commonly confused concepts

• GATS vs GATT: GATT (1947, updated 1994) covers trade in goods and works mainly through tariffs. GATS (1995) covers trade in services and works through rules on market access and national treatment, because services usually do not face tariffs at a border.
• Mode 1 vs Mode 2: In Mode 1, the service travels (online advice, software). In Mode 2, the customer travels (tourism, studying abroad, medical tourism).
• Mode 3 vs FDI: Mode 3 is the services-trade view of setting up a business abroad. When a foreign bank opens a branch in India, it is both Mode 3 trade in services and FDI. But FDI also includes factories making goods, which is not GATS.
• Mode 4 vs migration: Mode 4 covers only temporary movement to supply a service. A person moving to another country to settle or to look for a permanent job is migration, which GATS does not cover.
• Market access vs national treatment: Market access is about whether foreigners can enter at all, and in what numbers or form. National treatment is about whether, once inside, they are treated as well as local firms.
• MFN vs national treatment: MFN means equal treatment among foreign countries. National treatment means equal treatment between foreign and domestic suppliers.

Issues, criticism and the way forward

• Mode 4 stays the weakest mode: rich countries tie Mode 4 to their immigration policy and keep visa rules tight. So professionals face quotas, salary thresholds and long visa processes, even when GATS or FTA promises exist.
• Hard to measure: services trade is hard to track. Official balance-of-payments data mostly capture Modes 1, 2 and 4, while Mode 3 needs separate data on foreign companies. The WTO's estimates by mode are partly experimental.
• Slow WTO talks: the services talks under the Doha Round have made little progress. Much opening of services now happens through FTAs and plurilateral deals instead of GATS.
• Policy space: some countries and experts worry that strong GATS commitments in sectors like health, education or water could limit a government's freedom to regulate for public needs. Others argue that commitments are voluntary and can be designed carefully.
• Way forward: experts suggest that India keep seeking stronger Mode 4 promises (visa ease, recognition of professional degrees through Mutual Recognition Agreements, social security agreements), protect its Mode 1 strength in digital trade, and improve data on services trade by mode.

Concepts to Know

• World Trade Organization (WTO): The global body, set up on 1 January 1995, that makes and enforces rules for trade between countries. It is based in Geneva.
• Tariff: A tax that a country charges on goods coming in from abroad.
• Uruguay Round: The round of world trade talks from 1986 to 1994. It created the WTO and brought services (GATS) and intellectual property (TRIPS) under trade rules for the first time.
• Natural person: A real human being, as opposed to a company (which is called a "legal person" or "juridical person" in law).
• Schedule of specific commitments: A country's official list, filed at the WTO, of which service sectors it opens to foreigners, in which modes, and with what limits.
• Plurilateral agreement: A deal signed by only some WTO members who choose to join, unlike a multilateral agreement that binds all members.
• Social security agreement (totalisation agreement): A deal between two countries so that a worker posted abroad for a short time pays pension or social security contributions in only one country, not both.
• Mutual Recognition Agreement (MRA): A deal in which two countries accept each other's professional degrees or licences, so that, for example, an Indian nurse or architect can work in the other country more easily.
