Measuring financial market integration in the European Union: EU15 vs. New Member States

ENThis paper quantifies financial market integration in the European Union, using a large array of credit and bond market indicators, stock market indicators, as well as indicators based on household and firm decisions. It focuses on comparing the evolution of the European Union before the Eastern enlargement (EU15) with that of the 12 New Member States (NMS) that joined after 2000. It documents improvements in the integration of the credit and bond markets as well as stock markets for both groups within the EU27, the heightened heterogeneity brought about by the NMS, but also a reversal of the integration process over the recent years (corresponding to the financial crisis), divergence disrupting both the EU15 core and the NMS. For all the decades of achievements within both the EU15 and NMS groups in terms of credit and stock market integration, the ultimate goals of financial market integration, perfect capital mobility and full international risk sharing remain out of reach.
