The G20 Leaders' Summit is the apex annual gathering of the Group of Twenty, an intergovernmental forum comprising nineteen sovereign economies plus the European Union and, since the New Delhi Summit of September 2023, the African Union as a permanent member. The G20 was constituted in 1999 at the finance-minister and central-bank-governor level in the wake of the Asian financial crisis, but was elevated to leaders' level in November 2008 when U.S. President George W. Bush convened the inaugural Washington Summit during the global financial crisis. The grouping has no charter, no permanent secretariat, and no founding treaty; it operates through a rotating presidency and produces consensus-based, legally non-binding Leaders' Declarations. Its members collectively account for roughly 85 percent of global GDP, 75 percent of world trade, and two-thirds of the world's population, making it the premier forum for international economic cooperation.
The Summit functions through a dual-track architecture. The Sherpa Track, led by each leader's personal representative (the "Sherpa"), handles socio-economic and political agenda items, while the Finance Track, run by finance ministers and central bank governors, addresses fiscal, monetary, and financial-regulation matters. Negotiations across working groups, ministerial meetings, and engagement groups (such as Business 20, Civil 20, and Youth 20) culminate in the Leaders' Declaration. The presidency rotates annually among five regional groupings, and continuity is maintained through the Troika — the immediate past, current, and incoming presidencies working in tandem. Decisions rest entirely on consensus and peer pressure rather than enforcement, distinguishing the G20 from treaty-based institutions like the IMF or WTO.
India held the G20 presidency in 2023 under the theme Vasudhaiva Kutumbakam ("One Earth, One Family, One Future"), hosting the New Delhi Summit on 9–10 September 2023, which admitted the African Union and launched the India–Middle East–Europe Economic Corridor (IMEC) and the Global Biofuels Alliance. Brazil held the 2024 presidency, hosting the Rio de Janeiro Summit and launching the Global Alliance Against Hunger and Poverty. South Africa assumed the presidency in 2025 — the first on African soil — under the theme "Solidarity, Equality, Sustainability." The United States holds the 2026 presidency, with the Summit scheduled to be hosted by President Donald Trump, marking the forum's return to North America since 2008.
For the exam, the G20 is heavily tested in current-affairs and global-institutions papers across UPSC (GS Paper II — international institutions), FSOT, and CSS. Aspirants must master the membership (note the AU's 2023 admission and that Spain is a permanent guest, not a member), the 2008 origin and 1999 finance-level founding, the Sherpa/Finance dual-track and Troika mechanisms, and the sequence of recent presidencies and their flagship outcomes. Typical question angles compare the G20's non-binding consensus model with the binding frameworks of the UN Security Council or WTO, assess India's 2023 deliverables, and probe the forum's role in debt relief, climate finance, and reform of multilateral development banks.
Example
