Since its upgrading to heads of government level in late 2008, the G20 claims to be the steering committee for the world economy. It claims three specific big successes: stronger international financial regulation, including the Basel 3 Capital Accord; more effective macroeconomic coordination; and governance reforms of the Bretton Woods organizations. This paper challenges all three claims, but concentrates on the Basel 3 Accord. The modesty of the achievement leaves the world vulnerable to more multi-country financial crises, and testifies to the ineffectiveness of the G20 as presently constituted.
