(71)Access to adequate liquidity resources is essential for a CCP. It is possible for such liquidity to derive from access to central bank liquidity, creditworthy and reliable commercial bank liquidity, or a combination of both. Access to liquidity could result from an authorisation granted in accordance with Article 6 of Directive 2006/48/EC or other appropriate arrangements. In assessing the adequacy of liquidity resources, especially in stress situations, a CCP should take into consideration the risks of obtaining the liquidity by only relying on commercial banks credit lines.
