Central bankers no longer supermen of global financial economy [audio 23min]

For the last six decades, central bankers from the most developed countries have managed the global economy and have rarely broken into a sweat. They have run the international financial system, suppressing inflation when needed and creating the stability necessary for our economies to flourish, with the aid of a powerful set of economic levers handed to them after the Second World War. Last year these levers came off in their hands. The central banking system has suffered a chronic power outage. Robert Peston examines how those who were once the supermen of the global financial economy became seven stone weaklings. Preston is Business Editor for BBC News.
