Abstract: This short communication examines the convergence of the Tier 1 capital ratio in the banking sector across the EMU. The study applies the Phillips-Sul convergence and clustering algorithm for 251 European banks over annual periods from 1990 to 2010. The null hypothesis of full convergence is rejected; however, the convergence tests reveal heterogeneity in the Tier 1 capital ratio in the European banking sector, with five distinct clusters.
