Martin and Summers conceived of the G20 in response to the series of massive debt crises that had spread across emerging markets in the late 1990s, beginning with the Mexican peso crisis and followed by the 1997 Asian financial crisis, the 1998 Russian financial crisis, and eventually impacting the United States, most prominently in the form of the collapse of the prominent hedge fund Long-Term Capital Management in the autumn of 1998. It illustrated to them that in a rapidly globalizing world, the G7, G8, and the Bretton Woods system would be unable to provide financial stability, and they conceived of a new, broader permanent group of major world economies that would give a voice and new responsibilities in providing it.
