This paper investigates two issues that have not been addressed in Basel III and which are of particular importance for the attainment of a more effective liquidity regulation. The first is the need for a dynamic definition of liquidity that takes into account the time-varying liquidity and stability of banks’ balance sheet items. The paper develops a new liquidity ratio that explicitly considers this changing nature of liquidity, by assigning weights that depend on financial risks and perceptions. The ratio is estimated and assessed for the EMU-12 countries. The second issue is the need for macro fragility-related liquidity requirements. We provide empirical evidence which suggests that the banking sector does not self-impose such requirements. Based on this evidence, it is argued that the regulatory agents should introduce a positive link between bank liquidity and macroeconomic fragility. 38 pp. LOMv1.0 creator LOMv1.0 Scientific Coordinator LOMv1.0 Project Deliverable Number Π.Ε.4 LOMv1.0 Project Executing Organisation 2013 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Banks Liquidity Macroeconomic fragility 1365493 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/3267/2/3267_1.94_%ce%91%ce%9d_27_6_13.pdf URI http://hdl.handle.net/10795/3267 LOMv1.0creator 2016-05-19T10:09:44Z LOMv1.0validator 2016-05-19T10:09:44Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
