This is a link to an article in risk magazine regarding CCP recovery planning, and specifically loss allocation rules.
The article highlights differing views within the market regarding the extent to which loss-allocation rules within a recovery (but not necessarily a resolution) scenario should be flexible or prescriptive in nature. The article points to a paper published by the Bank of England in April 2013, which states that loss-allocation rules should provide a full and comprehensive description of the way in which losses would be allocated and be capable of being implemented quickly.
CCP loss-allocation rules play an important part in the recovery of financial market infrastructures, such as CCPs. However, as the CPSS/IOSCO paper on Recovery and resolution of financial market infrastructures makes clear, they are not one and the same thing. General recovery planning options must remain flexible in nature so as to allow firms to respond appropriately to financial stress scenarios the exact nature of which are impossible to determine before the event. Nonetheless, account must be taken of clearing members, given their systemic importance and the need for them to be able to effectively manage their own risks. As such, it must surely be the case that CCP loss allocation rules applied as part of the recovery process must provide a clear, detailed and transparent description of the way in which clearing members which would be liable for shortfalls at the CCP.
