We use data for 70 countries across developed, emerging and transition economies to estimate statistical connections between banking performance, the structure of bank supervision, permissible banking activities, legal environments, banking market structure and macro- economic conditions. We find that where central banks supervise banks, banks tend to have more non-performing loans. Countries with multiple supervisors have lower capital ratios and higher liquidity risk. We also find that conclusions from non-transition economies may not necessarily apply to transition economies. I. INTRODUCTION Debate about the appropriate structure and purview of bank supervision has taken on more urgency in recent years. 1 In part, this is because banking crises have become much more frequent in the past two decades than previously and have often imposed on taxpayers huge, direct resolution costs and indirect costs through disruptions to macroeconomic performance. 2 In addition, many transition economies privatized their banks and needed to build bank supervision virtually from scratch. Analytical and technological advances in telecom- munications further blurred traditional distinctions between banking and other * The authors would like to thank Richard Levich, John J.
