For a while, in the immediate aftermath of the Global Financial Crisis of late 2008, the G20 came into its own. This group of (self-styled) leaders of the global economy, representing governments in nations contributing more than half of global GDP, came together in April 2009 to pledge a co-ordinated response to unprecedented global economic threats. This not only had a role in staving off immediate disaster through the implementation of broadly Keynesian responses, but also promise more for the future. This was not just vainglorious self-importance on the part of these governments. There was a genuine absence of global institutions that were sufficiently small as to be coherent (something that was not as possible in the United Nations, given its size and structure) or even seen as generally reliable, flexible and aware (given how the IMF has discredited itself by awarding good marks to so many economies just before they imploded financially).
But since then, the drama in the world economy could even have been Hamlet without the Prince of Denmark, as Act 2 of the global financial crisis unfolds. In its subsequent meetings, the G20 has been much more about style than substance – and sometimes the style has also been lacking. At least, in its Seoul meeting in 2010, the G20 committed themselves to promoting inclusive and sustainable economic growth. They argued that ‘for prosperity to be sustained it must be shared’ and also endorsed ‘green growth’, which promised to decouple economic expansion from environmental degradation.
