In 2011 the G20 leaders decided that it would be expedient to adopt mandatory margining of non-centrally cleared derivatives to enhance the stability of the financial system. This decision complemented the program for reforming the OTC derivatives market approved at the G20 summit in Pittsburgh in 2009. The current draft of the Report contains the Bank of Russia’s position regarding the questions raised in the Initial Draft Report and the approaches ultimately adopted by the Bank of Russia to the implementation of mandatory margining of NCC derivatives based on face-to-face consultations with members of the professional community and based on comments and proposals sent before July 3, 2017, to svc_derivatives@cbr.ru. The results of the public discussion of the Initial Draft Report were reviewed by the Derivatives Board (DB). The current draft of the report will form the basis for corresponding draft Bank of Russia regulations.
