Jon - SwapClear's margin overhaul was primarily a function of clearing members telling the CCP that its IMs were too low. There's been a big drive of late from clearing members to emphasise "defaulter pays" and for shifting risk away from the default waterfall and back to the client and hence higher IMs.

Does anyone know what drove the change to happen i.e. internal improvements or external input from regulators, buy side, sell side firms or a combination and what the rationale was (prudent risk management, competitive margin levels, enabling portfolio margining, something else)?
