PwC's Managing upstream risk: Regulatory reform review - An asian perspective November 2013 | Page 7

The paper comprises a detailed set of proposals for a comprehensive revision of the market risk framework. This second consultative document provides more detail on the approaches introduced in May 2012, and sets out a draft text for a revised market risk framework. It has been informed by comments received on the first consultative paper, and lessons learnt from the Committee’s recent investigations into the variability of market risk-weighted assets. The key features of the proposed revised framework include: • A revised internal models-based approach, encompassing a more rigorous model approval process, and more consistent identification and capitalisation of material risk factors. Hedging and diversification recognition will also be based on empirical evidence that such practices are effective during periods of stress. • A strengthened relationship between the standardised and the models-based approaches – This is achieved by establishing a closer calibration of the two approaches, requiring mandatory calculation of the standardised approach by all banks, and requiring mandatory public disclosure of standardised capital charges by all banks, on a desk-by-desk basis. • A revised boundary between the trading book and banking book – The new approach aims to create a less permeable and more objective bound
