We examine the level and progress of bond market integration amongst the eleven Economic and Monetary Union countries with active bond markets, over normal and crisis periods. The study covers data from January 2002 up to March 2014. We employ seven indicators for assessing integration, namely beta convergence, sigma convergence, variance ratio, Asymmetric Dynamic Conditional Correlation, dynamic co-integration, market synchronisation, and common factors approach. The results suggest that there is no heterogeneity in the integration process of large-sized economies and medium-sized economies, thereby restricting portfolio diversification potential. Further, bond market integration in the Economic and Monetary Union deteriorated during the crisis period, especially during the European debt crisis, with the economies of Greece, Ireland, Italy, Portugal, and Spain being the worst affected. We observe that bond markets take a lead in information linkages vis-à-vis stock markets, and hence should get precedence in policy intervention relating to market integration, development, and crisis management.
