The correct option is World Trade Organisation (WTO).
Explanation
The international economic architecture is supported by distinct institutions, each with a specific mandate covering monetary stability, development finance, and trade regulation.
- International Monetary Fund (IMF) is incorrect: The International Monetary Fund (IMF) is mandated to ensure the stability of the international monetary system. Its primary focus is on exchange rates, balance of payments support, and global financial cooperation, not the regulation of merchandise or services trade.
- World Bank is incorrect: The World Bank is primarily a development institution. It focuses on reducing poverty and promoting shared prosperity by providing low-interest loans, zero to low-interest credits, and grants to developing countries for investments in education, health, infrastructure, and other areas.
- World Trade Organisation (WTO) is correct: The World Trade Organisation (WTO) is the only global international organization dealing with the rules of trade between nations. Established in 1995 under the Marrakesh Agreement, it acts as a forum for trade negotiations, administers trade agreements, and operates a dispute settlement mechanism to enforce compliance with global trade rules.
- United Nations Conference on Trade and Development (UNCTAD) is incorrect: The United Nations Conference on Trade and Development (UNCTAD) is a permanent organ of the UN General Assembly. While it deals with trade, investment, and development issues, its role is primarily policy analysis, research, and technical cooperation to support developing countries. It does not have the mandate to enforce binding global trade rules or settle disputes like the WTO.
Key Takeaway: The WTO is the specific body responsible for establishing and enforcing global trade rules, whereas the IMF and World Bank focus on financial stability and economic development, respectively.
