Charles Goodhart is the senior British economist specialising in financial stability issues. As the turmoil began, continued and exploded into crisis, he has kept up a series of commentaries, all since September 2007. These have been brought together, plus some new and additional material, to provide the reader with an overview of what went wrong in the regulatory framework for the financial system, and what now needs to be done to put that right. This will be required reading for financial regulators, practitioners in banking and finance, academics and students of finance, and those just wanting to know what went wrong and what to do now.
