The Libor manipulations successively discovered, led the British Government to request to the Financial Services Authority (FSA) a report to reform the system. On August 10, 2012, a progress report is made public. It proposes not to end self-regulation, but to temper it. Firstly, the declaratory system, too subjective, must be tempered by objective data (real transactions and other reference rate). Secondly, the power of monitoring and sanction of public authorities must be increased. This growing power must be that of the courts... and the Financial Services Authority (FSA). Stakeholders have until September 7, 2012 to respond. The British Government has entrusted in late July 2012 the Financial Services Authority (FSA) a report on the reform that is appropriate to operate concerning the system of Libor. It must be submitted at the end of September. Subsequent events show the method followed.
