The G20 in Transition

Multilateral cooperation has never been more necessary and more fragile. The conclusion of South Africa’s G20 presidency closed a rare cycle of Global South leadership, during which debt sustainability, climate finance, and inequality moved from the margins to the centre of global governance. Johannesburg demonstrated that African and emerging economy priorities can boldly shape the agenda rather than simply react to it.

But progress is precarious. The transition to the U.S. presidency in 2026 signals a sharp ideological shift that could fracture already thin consensus. The G20 remains one of the few forums where major economies engage as peers, yet its ability to translate shared language into collective action, which has been in question for some time, is now further weakening. The upcoming transition is not a procedural shift — it reflects a collision between two worldviews: a solidarity-driven development agenda and a more transactional, unilateral approach.

Washington’s partial boycott of the summit, combined with signals that South Africa may not be included in core elements of the U.S. presidency, confirmed what has been building for several cycles: the G20 is no longer operating as a forum of shared stewardship. It is a contested space where participation is conditional on geopolitical alignment.

1. Consensus Survives through Absence, Not Alignment

The Johannesburg Leaders’ Declaration reflects the new mechanics of global consensus. Commitments appear, but obligations dissolve in phrasing calibrated to avoid confrontation. Climate language survives but softened into voluntary pathways, dependent on national contexts. References to conflicts, including Palestine, Sudan, and the Democratic Republic of Congo, are framed as humanitarian issues, to avoid assigning geopolitical responsibility. The Leaders Declaration also exposes the G20’s core tension: the agenda keeps expanding, yet the political space to land concrete commitments continues to shrink. And yet, the document exists — not because alignment was reached, but because members refused to let boycott or obstruction collapse the process entirely. That precedent matters.

2. Where Politics Fails, Multistakeholder Cooperation Continues

A striking feature of Johannesburg Summit was the divergence between political paralysis and technical progress. While leaders struggled to maintain cohesion, the T20, B20 and other Engagement  Groups continued advancing dialogue, building coalitions and preserving channels of trust at a moment when trust is scarce. These tracks matter. They hold the system together when formal diplomacy stalls.

Even if the space for engagement groups contracts under the next presidency, their relevance should not be underestimated. The G20’s future legitimacy may depend less on headline political agreement and more on what technical bodies can quietly continue to deliver.

3. The U.S. Presidency Signals a Hard Pivot

The transition to the United States presidency represents an ideological rupture rather than a routine rotation. The agenda will shift from the Global South’s solidarity model to a transactional, security-driven approach. Critical minerals illustrate this friction. South Africa’s proposed framework for “beneficiation at source” challenges historic extractive models. Under the U.S. presidency, this framework risks becoming irrelevant as American policy pivots toward bilateral security agreements to insulate domestic industry. Multilateralism effectively becomes optional.

4. The G20’s Future Depends on Continuity

If each presidency resets the agenda, the G20 becomes an annual signalling exercise rather than a governance platform. The forum’s utility depends on whether continuity can survive despite political volatility. If it cannot, the G20 ceases to be a stabilising architecture or a productive platform for global problem-solving. The handover from Johannesburg to Miami did not resolve this existential question. It merely exposed it. The next 18 months will likely define the G20’s trajectory. Rather than a binary outcome of success or failure, we should anticipate a structural evolution in how the forum operates.

Strategic Outlook:

The Emergence of Multilateralism 2.0

In this fragmented landscape, the following trends will likely shape the strategic environment:

• The Shift to “Multilateralism 2.0”: We are likely moving away from universal consensus toward a “minilateral” model. Progress can be expected to stem not from all 20 members agreeing on a single text, but from smaller coalitions advancing specific high-value agendas (e.g., AI safety, critical minerals), while others opt out. This “variable geometry” allows for movement despite gridlock at the top level.
• Resource Security via Bilateral Channels: The era of broad globalized supply chain frameworks appears to be receding. It is probable that resource governance will increasingly be managed through bilateral agreements and security partnerships, rather than through new multilateral trade rules.
• Strategic Engagement, Not Withdrawal: The Finance Track will remain essential, because systemic economic risks like debt distress, market volatility, financial instability and digital currency regulation cannot be managed outside multilateral coordination. Disengagement here is not an option. But focusing solely on the Finance Track would leave a dangerous vacuum.The Sherpa Track has long been the arena where civil society, business, academia and multilateral actors feed ideas into the political process. If its space contracts under the next presidency, the risk is not just weaker dialogue — it is the erosion of pluralism inside global governance. The task, therefore, is not withdrawal but consolidation. Engagement Groups including the B20, C20 and T20 will need to coordinate more tightly to maintain a coherent voice rather than acting in parallel silos. The priority is to protect and strengthen the platforms that can still function as safe harbors for dialogue: spaces where expertise, evidence and societal interests can continue informing the agenda even as political bandwidth narrows.
• Strategic Bridge-Building (2026–2027): A key opportunity for stability lies in the sequencing of upcoming presidencies. There is a clear strategic opening to harmonize the French G7 Presidency in 2026 with the preparations for the UK’s G20 Presidency in 2027. This coordination offers a stability corridor, allowing these powers to align agendas and preserve institutional norms across the G7 and G20, potentially insulating the multilateral architecture from volatility during the intervening period.

The coming cycle will test whether the G20 remains a platform for collective problem-solving or becomes constrained by unilateral ambition and great-power assertiveness. What happens next will determine not only the institution’s relevance, but the future of global economic cooperation itself.
