(5)Article 7a(3), point (b) of Regulation (EU) No 648/2012 requires counterparties to have systems and resources available to be operationally able to use the active account, even at short notice, for large volumes of derivative contracts. Article 7a(3), point (c) of that Regulation requires that all new trades in the derivative contracts can be cleared in the active account at all times. Counterparties should therefore have the necessary internal systems and dedicated resources to monitor their exposures, and the internal arrangements to use the account when the clearing volumes increase, including the possibility to assess any potential legal or operational barriers that could prevent them or impair their ability to onboard a significant amount of additional transactions.
