G20

The G20, or Group of Twenty, is an informal forum that brings together major advanced and emerging economies to discuss global economic governance. Its members include large national economies, the European Union, and the African Union, giving it wider representation than the G7.

The forum began in 1999 at the level of finance ministers and central bank governors after financial crises in the 1990s. It was elevated to a leaders' summit during the 2008 global financial crisis, when major economies needed broader coordination on banking stability, stimulus, financial regulation, and recovery.

The G20 is not a treaty organization and does not directly enforce its decisions. Its influence comes from political coordination among systemically important economies, support from international institutions, and the ability of members to shape rules through national policy, central banks, finance ministries, and multilateral bodies.

The G20 matters because its members represent a large share of global GDP, trade, investment, population, emissions, and financial activity. When G20 members coordinate, they can influence interest-rate spillovers, financial regulation, debt restructuring, climate finance, development lending, trade policy, and crisis response.

Its finance track is especially important. Finance ministers and central bank governors discuss macroeconomic risks, inflation, debt vulnerabilities, international tax, financial stability, development finance, and reforms to institutions such as the IMF and World Bank.

Geopolitically, the G20 exposes the tension between developed and emerging powers. It is more representative than the G7, but that wider membership also makes consensus harder on war, sanctions, debt relief, climate responsibility, trade rules, and reform of global financial institutions.
