India is the fastest-growing major member at +6.2 percent; Germany is the slowest at +0.6 percent. The G20 was created in 1999 to give large emerging economies a seat at the global economic table.

The G20 in Context

The G20 was established in 1999, originally as a finance-ministers meeting, in response to the late-1990s emerging-market crises. It was elevated to a leaders' summit in 2008 during the global financial crisis. The bloc represents around 75 percent of world GDP, around 80 percent of world trade, two-thirds of world population, and around 80 percent of global greenhouse gas emissions.

Unlike the G7, the G20 includes large emerging-market democracies (India, Brazil, Indonesia, South Africa, Mexico, Turkey, South Korea), one autocracy (China), and Russia (whose membership has continued despite the 2022 invasion of Ukraine, though leaders have not met in person with Russian counterparts since). The African Union was admitted as a permanent member in September 2023, bringing 55 additional countries into the orbit.

The G20's legitimacy as the primary global economic forum derives from this breadth. The IMF reform proposals, climate-finance commitments, debt-restructuring frameworks for low-income countries, and global tax-floor agreements have all been negotiated through G20 working groups before formal adoption at multilateral institutions.
