| G7 vs G20 vs BRICS describes three separate international forums that differ in membership size, economic weight, and decision-making power, and none of the three holds any binding legal authority over its member states. This guide breaks down who sits at each table, how each forum actually reaches decisions, and which one carries more economic weight once the numbers are compared directly. Universalnest covers global governance structures like these as part of its Current Affairs coverage, tracking membership changes and economic shifts as they happen. |
What Is the G7? 7 Members, One Rotating Presidency, and How Decisions Get Made
The G7 is a seven-member forum of advanced economies that meets annually through a leaders’ summit chaired by a rotating presidency. The members are Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States, with the European Union sitting in as a standing participant across all sessions.
| G7 Detail | Value |
| Members | Canada, France, Germany, Italy, Japan, UK, US |
| Standing participant | European Union |
| 2026 presidency | France |
| 2026 summit location | Évian-les-Bains, 15 to 17 June |
| Decision mechanism | Non-binding communiqué after each summit |
The presidency rotates among the seven member states every year, and the host country sets the agenda and invites additional non-member leaders for specific working sessions. The 2026 summit under the French presidency focused on child protection online, organized crime and drug trafficking, critical minerals, and coordinated responses to ongoing geopolitical conflicts.
What the G7 actually produces is a joint communiqué, a written statement of shared positions on security, trade, technology governance, and sanctions. It carries political weight because it reflects the alignment of seven major economies, but it creates no legal obligation. Each government still has to turn those shared positions into its own domestic policy for anything to change.
What Is the G20? 19 Countries, Two Decision Tracks, and 80% of Global GDP
The G20 is a 19-country forum plus the European Union and the African Union, built specifically to coordinate global economic and financial policy among the world’s largest economies. Spain attends as a permanent guest despite not holding formal membership.
| G20 Detail | Value |
| Member countries | 19, plus the EU and the African Union |
| Permanent guest | Spain |
| Share of global GDP | Around 80% |
| Share of global trade | Around 75% |
| Founded | 1999, elevated to leaders’ level in 2008 |
| Governance structure | Troika system with Finance Track and Sherpa Track |
The G20 began as a meeting of finance ministers and central bank governors in 1999, created in response to the Asian financial crisis. It became a leaders’ summit only in 2008, after the global financial crisis made it clear that economic coordination needed heads of state at the table, not just their finance officials.
Its governance runs on two parallel tracks. The Finance Track handles monetary and fiscal policy discussions among finance ministers and central bankers. The Sherpa Track handles broader political and development issues through personal envoys of each leader. A Troika made up of the current, previous, and next presidency holders keeps continuity between annual summits, since the G20 has no permanent secretariat or headquarters.
G20 decisions are consensus-based declarations, not enforceable law. Member states commit to shared targets on trade, climate finance, and digital economy policy, but implementation depends entirely on each government’s own political will.
What Is BRICS? Founding Members and the 2024–2025 Expansion
BRICS began in 2009 as a four-country grouping of Brazil, Russia, India, and China, joined by South Africa in 2011 to form the original five-member bloc. Since 2024, BRICS has expanded twice, changing its scale significantly.
| BRICS Expansion Timeline | Members Added |
| 2009 founding | Brazil, Russia, India, China |
| 2011 addition | South Africa |
| 2024 expansion (effective Jan 1) | Egypt, Ethiopia, Iran, Saudi Arabia, United Arab Emirates |
| 2025 expansion | Indonesia |
| 2026 chairship | India, hosting the 18th BRICS Summit in New Delhi |
The 2024 additions were announced at the Johannesburg summit and admitted Egypt, Ethiopia, Iran, Saudi Arabia, and the United Arab Emirates as full members from January 1, 2024. Indonesia joined as a full member in 2025, bringing the bloc’s practical membership closer to eleven countries once partner states are included in broader counts.
BRICS runs on the same consensus principle as the G7 and G20, with no permanent secretariat and no binding enforcement mechanism. Its stated focus includes economic cooperation among member states, support through the New Development Bank, and ongoing discussion around reducing reliance on the US dollar in cross-border trade. For the full breakdown of which countries joined and what the expansion means for dollar dominance specifically, see our dedicated coverage on BRICS Expansion 2024 to 2026 and its effect on the currency system.
G7 vs G20 vs BRICS – Membership Size, Founding Year, and Decision Power Compared
Placed side by side, the three forums differ across four measurable dimensions: how many countries sit at the table, when each one started, how each one governs itself, and whether any of them can force a member to act.
| Dimension | G7 | G20 | BRICS |
| Members | 7 + EU | 19 + EU + AU | 10 to 11 (post-expansion) |
| Founded | 1975 | 1999 (leaders’ level 2008) | 2009 |
| Decision mechanism | Consensus communiqué | Consensus declaration (Troika-led) | Consensus declaration |
| Binding authority | None | None | None |
| Primary focus | Security, trade, tech governance among advanced economies | Global economic and financial stability | Emerging economy cooperation, de-dollarisation |
The clearest distinction is not decision-making power, since all three operate on consensus with no legal force. The real difference is composition and focus. The G7 represents a fixed group of advanced economies coordinating on security and strategic policy. The G20 is a broader economic coordination body built specifically around financial stability across both advanced and developing economies. BRICS is a growing bloc of emerging and developing economies coordinating around economic cooperation and reduced dependence on Western financial systems.
G7, G20, and BRICS by GDP and Population – PPP vs Nominal Compared
Whether BRICS or the G7 is described as the larger economic bloc depends entirely on which measurement is used, nominal GDP or purchasing power parity GDP, and this is where most comparisons get confusing.
| Metric | G7 | G20 | BRICS (expanded) |
| Share of global GDP (nominal) | Roughly 30% to 40% | Around 80% | Around 26% to 30% |
| Share of global GDP (PPP) | Lower than BRICS on this basis | Includes both blocs’ totals | Around 40%, has overtaken G7 on PPP terms |
| Share of world population | Under 10% | Roughly two thirds | Close to half |
Nominal GDP converts every country’s output into US dollars at market exchange rates, which favors economies with strong currencies like the G7 members. Purchasing power parity adjusts for what money actually buys within each country, which favors large, lower-cost economies like China and India. On a PPP basis, the expanded BRICS bloc has overtaken the G7 in total economic output, largely because of China and India’s domestic purchasing power. On a nominal basis, the G7 still holds a larger combined GDP. Both statements are accurate. They are just measuring different things.
Do G7, G20, or BRICS Decisions Carry Legal Force? None of the Three Can Bind Members
None of the three forums has the legal authority to force a member country to act, since each one operates purely through consensus and voluntary follow-through. A G7 communiqué, a G20 declaration, and a BRICS summit statement are all political commitments, not treaties.
This distinction matters because it explains why announcements from these summits do not automatically become law. A country can sign onto a joint statement at a G20 summit and still fail to implement the underlying policy domestically, since there is no external enforcement body, court, or penalty tied to these agreements. Follow-through depends entirely on each government’s own legislative process and political priorities once the summit ends.
Frequently Asked Questions
What is the main difference between the G7 and the G20?
The G7 is a fixed group of seven advanced economies focused on security and strategic coordination. The G20 includes 19 countries plus the EU and African Union, built specifically around global economic and financial policy coordination across both advanced and developing economies.
Is BRICS bigger than the G7?
On a purchasing power parity basis, the expanded BRICS bloc has overtaken the G7 in combined economic output. On a nominal GDP basis, measured in market exchange rate dollars, the G7 still holds the larger share.
Can a country be a member of more than one forum?
Yes. Several countries, including Brazil, China, India, Saudi Arabia, and South Africa, hold membership in the G20 while also being part of BRICS, since the two forums are not mutually exclusive and serve different coordination purposes.
Who decides which country joins the G20 or BRICS?
G20 membership was set when the forum was created in 1999 and has not formally expanded since, aside from the African Union’s recent inclusion. BRICS admits new members through consensus agreement among existing full members, as seen in the 2024 and 2025 expansions.
What does the rotating presidency actually control?
The rotating presidency sets the annual agenda, hosts the summit, and can invite additional non-member leaders to specific sessions, but it does not gain any extra voting power or authority over other member states.
Is BRICS meant to replace the G7 or G20?
BRICS positions itself as an alternative coordination platform for emerging and developing economies rather than a direct replacement, though its growing GDP share and de-dollarisation discussions increasingly position it as a counterweight to G7-led financial systems.
