Towards Reconstitution of the G20

Prof. Dennis J. Snower

The UK’s 2027 G20 Presidency arrives at a constitutional moment for global governance. The UK has formally confirmed that it will host the G20 in 2027, and official UK statements in early 2026 indicate that initial plans are already being discussed with major partners. That matters because the G20 itself was elevated to leaders’ level in the 2008 financial crisis; in other words, it was born as an adaptive response to systemic breakdown, not as a fixed constitutional order.
