A decade ago the world was struggling with the repercussions of the global financial crisis in 2007 and 2008 that emerged in the interconnected transatlantic financial system. At this critical moment in time, the G20 was elevated from a meeting of finance ministers and central bank governors to the level of heads of states and government. By including a number of rising as well as middle powers non G7 countries the first G20 summit in Washington in November 2008 made clear that current cross-border challenges cannot anymore be dealt with by the old powers of the traditional establishment. At the subsequent summits in London (April 2009) and Pittsburgh (September 2009) the G20 displayed an astonishing level of international cooperation by agreeing on wide-ranging commitments that helped to calm down international financial markets and strengthen the crisis response of international financial institutions. These early initiatives led some optimistic observers to conclude that the system worked.


For 2019, the global challenges are unlikely to become fewer than in 2018, based on the past experiences. The post-cold war international order as we knew it has taken a few blows again in 2018. Some key pillars and narratives are being shifted and challenge the stability of the international architecture. As often with foreign relations, it takes place in a context that consists of both global challenges and domestic priorities. Indicators for change will thus be located in domestic politics of some key countries. Without wanting to sound overly optimistic for a surely difficult year to come, some elements for a change are visible.
In Buenos Aires on 30 November and 1 December 2018, the G20 is having its 10th anniversary as a summit format at the leaders’ level. On 14 and 15 November 2008, this previously-obscure group of finance ministers and central bankers of the nineteen most “systemically relevant” countries and the EU was transformed into a forum for international leaders to meet with a view into the abyss of the global financial crisis that originated in the US and spread fast across the world. Ten years and 12 leaders’ summits later, the G20 has moved beyond its 2008-09 role as a crisis-management forum and became the self-described “premier forum for […] international economic cooperation.” In this capacity it is now facing new demands to tackle global challenges such as climate change, digitalization and pandemics. As its agenda has expanded and the urgency of the crisis fades, the G20 faces questions regarding its relationship to other formal institutions of global governance, such as the United Nations, its effectiveness in dealing with global challenges as well as its legitimacy and accountability vis-à-vis its people and the 174 non-members.
