Re 1) Mandatory separation of high-risk trading activities i.e. compartmentalization, or “ring-fencing” of proprietary and third-party trading activities, without breaking banks up is to include risk management and capital allocation: “the trading division will have to hold its own capital, meaning that it stands or falls by its own activities and cannot, in theory at least, knock over the bread-and-butter retail banking operations." Universal banks with very large trading arms either in absolute terms (over €100bn-£80bn-$130bn-¥10.2tr-Y821bn) or in proportion to the rest of the bank (greater than 15%-25%) should be forced to hold separate capital for its trading operations.
