The G20 was constituted in 1999 as informal discussion forum for the finance ministers and central bank governors of the 20 systemically most important economies at the time, in the aftermath of the Asian financial crisis of 1997–98. Its purpose was to address and counter the financial fallout and contagion brought about by the Asian financial crisis, as well as preceding and subsequent crises, such as the Mexican peso crisis of 1994 and the Russian financial crisis of 1998. Following the 2008 global financial crisis, it was elevated to the level of heads of state/government and designated the ‘premier forum for international economic cooperation’. While the G20 initially focused on broad macroeconomic policy, its scope has since expanded to include governance, finance, digital economy, education, agriculture, trade, sustainable development, energy transitions, health, climate change and the environment, among other issues. The purpose of the G20 is to bring together the world’s major economies to discuss and coordinate economic and financial policies to create a more stable and prosperous global economy through international cooperation and coordination.
The G20 has hosted annual summits under the leadership of a rotating presidency among its member states since 2008. In the absence of a permanent secretariat, the G20 member country holding the presidency is assisted by the countries holding the previous and upcoming presidencies, representing the troika, to set the agenda for each year’s summit. The G20 process is led by the sherpas of member countries, who are personal emissaries of the leaders. The sherpas oversee negotiations throughout the year, discussing agenda items for the summit and coordinating the substantive work of the G20.
The G20’s work is divided into two tracks: the Finance Track and the Sherpa Track. Within these tracks, there are thematically oriented working groups, which include representatives from the relevant ministries of member countries, invited/guest countries and various international organisations. These working groups meet regularly throughout the term of each presidency. The agenda is informed and influenced by the contemporary geopolitical and economic context of each presidency, as well as by the tasks and goals agreed upon in previous years. The figure below illustrates the G20 governance structure with the areas covered under each of the tracks.
As part of the G20 members’ commitment to consult relevant stakeholder communities, dialogue is facilitated through various engagement groups. These groups often draft recommendations for the G20 Leaders, contributing to the policymaking process. The engagement groups are as follows:
The G20 leadership is based on the principle of annual rotation among its members, which host annual summits where decisions of mutual interest are made by consensus. Brazil is the current president of theG20, with South Africa stepping into this role in December 2024. South Africa’s G20 Presidency marks the end of the first round of rotating G20 presidencies. The United States of America will begin the second round of rotating presidencies in 2026. To ensure continuity between presidencies, there is a troika system, which was adopted at the Cannes Summit in France in 2011. The troika is made up of the incumbent presidency, the previous and the next presidencies.
Each presidency ends with a summit where the leaders of member countries gather to discuss and adopt a declaration that draws on the work down by the various work streams in the sherpa and finance tracks over the course of the year. These declarations are consensus-based commitments on policies agreed upon by the member countries that set the tone for international economic and political coordination and cooperation. While the G20 does not have enforcement power, its decisions and statements influence national policies and the agendas of international multilateral organisations such as the International Monetary Fund (IMF), World Bank and World Trade Organization (WTO). The declarations also serve as a mechanism for holding member countries accountable to their commitments and fostering peer pressure to implement agreed-upon policies. By providing a platform for dialogue and cooperation, the G20 summits and declarations play a crucial role in addressing global challenges and shaping the international order.
The G20 membership is made up of the world’s 19 major and systematically important economies and two continental unions. The members are Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Republic of Korea, Mexico, Russia, Saudi Arabia, South Africa, Türkiye, the UK, the US, the AU and the EU. Collectively, these members account for 85% of global gross domestic product, 75% of international trade and two-thirds of the global population. In addition, the G20 incumbent presidency, at its own discretion, invites guest countries each year to participate in the G20 proceedings.
Despite the G20’s pivotal role in Africa’s future, traditionally the grouping has not involved the African continent in its inner workings. Only one African country (South Africa) has been a permanent member since the formation of the grouping, until the AU was formally admitted during the 2023 Indian Presidency. Prior to the 2023 decision, the AU enjoyed observer status at the G20 alongside the AU Development Agency (AUDA-NEPAD). AUDA, as an agency of the AU, now participates in some of the working streams. Past G20 meetings were also attended by the UN Economic Commission for Africa (UNECA) and the African Development Bank (AfDB), and they continue to do so. The AU’s admission as a full member of the G20 is significant because of the G20’s ongoing focus on global financial architecture reform, an endeavour that is a priority for African economies.
