Gone are the days when G7 ruled the world: Editorial flash

At this year's G7 summit in Evian-les-Bains, France, participants debated a broad question that did not formally make it onto the summit agenda: how Europe should navigate a future in which United States priorities are increasingly unpredictable and increasingly centered on its own interests.

That stands in sharp contrast to the 2005 G8 summit in Gleneagles, Scotland, where leaders of the world's major industrialized economies gathered to discuss debt relief for developing countries and increased assistance to Africa.

That summit's slogan, "Make poverty history", reflected an ambition that extended beyond the interests of its own members, as well as a collective effort to address some of humanity's most pressing challenges.

The past two decades have witnessed the G7's agenda turn from efforts to solve global problems to internal security concerns, geopolitical rivalries, trade disputes, and strategic competition.

Development, poverty reduction, and global public goods have moved to the margins, while managing disagreements among allies has increasingly become a central task.

To make matters worse, the group appears incapable of solving even those inner problems.

When the US – long regarded as the anchor of the G7 – finds itself in trade conflicts with Europe, starts raising questions about long-standing security commitments, and openly challenges partners on issues ranging from defense spending to industrial policy, the G7's ability to shape global outcomes is inevitably weakened.

This is a natural result of a deeper transformation in the global economy.

According to data from the World Bank and the International Monetary Fund, G7 economies accounted for roughly 60 percent of global GDP around the year 2005, but that has fallen to just over 40 percent in recent years.

Economic output is not the sole measure of international influence, but it remains one of its most important foundations because those who produce less have a smaller voice.

G7 members remain among the world's most advanced economies, yet the era in which a small club of developed nations can gather behind closed doors and largely determine the direction of the international system is clearly gone.

The world of 2026 is fundamentally different from the world of 2005. It is more multipolar, more interconnected, and more diverse.

The most pressing global challenges, including development and climate change, artificial intelligence, and economic governance, require broader participation and broader representation.

That reality is reflected in the growing importance of other multilateral platforms. The G20, elevated to a leaders' summit during the global financial crisis in 2008, brings together economies accounting for the overwhelming majority of global output and population. The expanded BRICS grouping has become an increasingly influential voice for emerging economies and the Global South. Even the OECD, founded long before the G7 itself, continues to provide an important framework for international economic cooperation.

The future of global governance will not be determined by a single club of rich nations, but rather shaped by a wider range of actors operating through more inclusive and representative institutions.

In that sense, the story of the G7 is not simply a story of decline, but one of transition, from a world once dominated by a handful of advanced economies to one in which influence, responsibility, and decision-making are increasingly shared across a broader international community.
