(39)The provisions of this Directive constitute steps in the reform process in response to the financial crisis. In line with the conclusions of the G-20, the FSB and the Basel Committee on Banking Supervision, further reforms may be necessary, including the need to build counter-cyclical buffers, ‘dynamic provisioning’, the rationale underlying the calculation of capital requirements in Directive 2006/48/EC and supplementary measures to risk-based requirements for credit institutions to help constrain the build-up of leverage in the banking system. In order to ensure appropriate democratic oversight of the process, the European Parliament and the Council should be involved in a timely and effective manner.
