The recent financial crisis has shattered all standard approaches to banking regulation. Regulators now recognize that banking regulation cannot be simply based on individual financial institutions’ risks. Instead, systemic risk and macroprudential regulation have come to the forefront of the new regulatory paradigm. Yet our knowledge of these two core aspects of regulation is still limited and fragmented. This book offers a framework for understanding the reasons for the regulatory shift from a microprudential to a macroprudential approach to financial regulation. It defines systemic risk and macroprudential policy, cutting through the generalized confusion as to their meaning; contrasts macroprudential to microprudential approaches; discusses the interaction of macroprudential policy with macroeconomic policy (monetary policy in particular); and describes macroprudential tools and experiences with macroprudential regulation around the world.

The book also considers the remaining challenges for establishing effective macroprudential policy and broader issues in regulatory reform. These include the optimal size and structure of the financial system, the multiplicity of regulatory bodies in the United States, the supervision of cross-border financial institutions, and the need for international cooperation on macroprudential policies.

Chapter abstract: Since the beginning of the financial crisis, academics and regulators on both sides of the Atlantic have started to debate the implications of securities trading by banks. New regulation limits security trading, fearing that this could crowd out lending to the real economy or could facilitate risk-shifting by financial institutions. On the other hand, banks may use security trading for hedging purposes or, particularly during a crisis, to access public liquidity. Only very recently have researchers begun to have access to micro data at the security level on banks’ trading activities, and they are starting to bring robust evidence on these issues. This chapter reviews the potential costs and benefits of combining traditional intermediation activity with security trading and discusses the recent empirical evidence.

Chapter abstract: The credit provided by banks is key to fund investment and consumption. In the euro area this is particularly true since bank loans represent the large majority of the credit going to the non-financial sector (corporates and households). How credit provision responds to monetary policy impulses is therefore a crucial question which policy makers are generally confronted with, in particular when a financial crisis strikes.

Chapter abstract: This article provides a comprehensive analysis of systemic risk, as the primary ingredient to understand financial crises and as a main rationale for banking regulation, prudential supervision, and crisis management. The second section provides the framework within which the theoretical and empirical literature is interpreted in the subsequent parts and briefly discusses its relevance for economic policy. The third section gives an overview of theoretical models explaining systemic risks in banking markets (including payment systems). The fourth section surveys econometric tests and some other quantitative empirical assessments of the various facets of systemic risk, focusing particularly on bank contagion but also on joint crises — for example, as caused by systematic shocks or the unravelling of imbalances that have built up over time. The fifth section concludes.
