The world's economic system is splitting apart. Today, global trade and finance are driven by a massive three-way power struggle. When we look at the G7 vs G20 vs BRICS divide, we see three entirely different game plans for the future. Each group wants to control the new rules of global money.
The 18th BRICS Summit in New Delhi made this competition obvious. The summit, which wrapped up on September 13, 2026, locked in new digital money networks and added more partner countries. Because of this, international capital now flows under competing sets of sovereign rules.
The numbers tell the real story. The Group of Seven (G7) holds just 9.5% of the world's population, but it still commands roughly 43% of global nominal GDP. On the other side, the newly expanded BRICS+ alliance now encompasses about 45% of the global population. More importantly, based on confirmed 2025 IMF data, BRICS+ now controls 40.7% of global GDP based on Purchasing Power Parity (PPP). The G7 has slipped to just 28.4% in this same metric.
Sitting right in the middle is the Group of Twenty (G20). It acts as the world's economic anchor. Following the recent addition of the African Union, the G20 now represents a staggering 85% of nominal GDP and over 80% of the human population.
| Structural Dimension | G7 (Group of Seven) | BRICS / BRICS+ | G20 (Group of Twenty) |

| Genesis & Formalization | 1975 (G6 summit); 1976 (Canada added) | 2006 (Dialogue); 2009 (Summit); 2024–2025 (Expansion) | 1999 (Ministers); 2008 (Leaders) |
| Current Membership | US, UK, France, Germany, Italy, Japan, Canada (+ EU) | 10 Full Members + 10 Official Partner States | 19 Sovereign States + European Union + African Union |
| Global Population Share | ~9.5% | ~45.0% | ~80.5% (with African Union) |
| Share of Global Nominal GDP | ~43.0% | ~28.0% | ~85.0% |
| Share of Global PPP GDP | ~28.4% | ~40.7% | ~78.0% |
| Primary Institutional Anchors | IMF, World Bank, OECD, BIS, Paris Club | New Development Bank (NDB), CRA | Financial Stability Board, IMF, WTO, WHO |
| Strategic Mandate | Rules-based order, asset immobilization, sanctions | Sovereign trade, local currencies, multipolarity | Macroeconomic coordination, debt workouts |
How These Blocs Were Born
To fully grasp the **G7 vs G20 vs BRICS** rivalry, we must look at how they started.
The G7 was born from the 1973 oil shock. French and West German finance chiefs held private meetings to fix a broken currency system. By 1976, Canada joined. The group quickly took control of global interest rates and energy supplies. The G7 does not have a formal treaty. Instead, its power comes from shared democratic values and massive financial markets.
BRICS started very differently. A Goldman Sachs economist coined the term "BRIC" in 2001. The concept predicted that emerging nations would outgrow the West by mid-century. By 2009, these nations held their first official summit. Their main goal? To push back against Western financial dominance.
This push got much stronger after Western nations froze $300 billion in Russian bank reserves. By January 2025, BRICS had added Egypt, Ethiopia, Iran, the UAE, and Indonesia. They also created a "Partner Country" tier. Adding ten new partners gave BRICS massive control over global shipping lanes.
The G20 was built to bridge this massive gap. Created after the 1997 Asian Financial Crisis, it was upgraded to a leaders' summit in 2008. World leaders finally realized the G7 could not fix a global banking crash on its own. Today, the G20 is the only place where G7 and BRICS leaders sit down together.
The Battle Over Money and SWIFT
The biggest fight in the **G7 vs G20 vs BRICS** showdown is over money systems.
The G7 controls the world's payment plumbing. They control the US dollar, Euro clearing channels, and the SWIFT messaging network. This gives them immense power. For example, in late 2024, the G7 gave Ukraine a $50 billion loan. They funded it entirely using the profits from frozen Russian assets. This proved that Western banking networks are powerful weapons.
To fight back, BRICS+ is building its own financial plumbing. They created the $100 billion New Development Bank (NDB). However, completely ditching the US dollar is very difficult. China has strict limits on taking money out of the country. Also, emerging markets do not have deep, safe bond markets like the US does.
To bypass these hurdles, BRICS+ is pushing Project mBridge. This is a shared digital ledger for central banks. Here is how it works:
- Central banks issue wholesale digital currencies (CBDCs) onto the platform.
- Commercial banks use this to send money instantly across borders.
- Transactions do not route through US banks or the SWIFT network.
This system eliminates high banking fees. More importantly, it hides commodity trades from Western sanctions.
Securing the Supply Chains
The global supply chain has split in two. The G7 wants to "de-risk." The US and Europe are spending billions to build their own microchips and green energy hardware. They believe relying on China is a massive security threat.
BRICS+ is taking the opposite approach. They are connecting the world's biggest energy sellers (Russia, Iran, UAE) with the biggest factory hubs (China, India).
The addition of 10 new Partner Countries changed the game. Adding Vietnam, Malaysia, and Thailand gives BRICS direct influence over global semiconductor manufacturing. Furthermore, Malaysia and Indonesia control the Strait of Malacca. Nearly one-third of all global sea trade passes through this narrow waterway. Partner status gives BRICS unprecedented power over these critical routes.
Where They Clash: Climate, Conflict, and AI
When these groups meet at the G20, talks often break down. The ideological divide is most obvious in three key areas:
- Climate Change: The G7 demands strict "net-zero" goals by 2050 and adds carbon taxes on imports. BRICS+ pushes back. They demand $100 billion in climate funding from the West. They argue that developing nations still need fossil fuels to escape poverty.
- Global Conflicts: The G7 acts as a unified military alliance, enforcing strict sanctions against Russia and Iran. BRICS+ refuses to follow Western sanctions. They choose to remain neutral and keep trading with whoever they want.
- Artificial Intelligence (AI): AI is the newest battleground. The G7 wants strict safety rules that protect Western tech companies. BRICS+ wants open-source technology. In 2025, BRICS launched its own AI framework to ensure they don't have to rely on Western systems.
News4Bharat POV
Many Western experts say BRICS+ is too divided to work. It is true that India and China have ongoing border disputes. The member countries also run their governments very differently. But judging BRICS by G7 standards misses the point entirely.
BRICS+ is a survival tool. Developing nations want protection from Western economic threats. By building new payment systems, BRICS lowers the danger of US sanctions. India plays a brilliant middle game here. New Delhi grows its trade through BRICS while keeping strong defense ties with the US and the Quad.
Meanwhile, the G20 is more important than ever. It is the only neutral ground left. If a global debt crisis hits, the G20 is the only room where Western lenders and Chinese banks will actually sit down and talk to each other.
The Bottom Line
The old world order is gone forever. Analyzing G7 vs G20 vs BRICS shows exactly how money will move in the future. The G7 will keep protecting its dollar dominance and tech secrets. BRICS+ will keep building alternate trade routes across the Global South. And the G20 will act as the crucial shock absorber between them.
For investors and businesses, the message is clear. You can no longer rely on a single global market. You must prepare to operate in a divided world. You need to follow G7 rules while preparing for new BRICS payment systems like mBridge.
