This study examines which financial stability responsibilities have been delegated to central banks (CBs), how these responsibilities are executed, and whether democratic accountability arrangements are in place. The results of our survey among all CBs in the OECD area suggest that there is no unambiguous definition of financial stability or systemic risk, and that, generally, the responsibility for financial stability is not explicitly formulated in laws. Moreover, there is considerable heterogeneity in the way CBs pursue the financial stability objective. Our results also suggest that the democratic accountability of the financial stability function of central banks is often poorly arranged.

It has been argued that central bank independence (CBI) may not only be beneficial for reaching the objective of price stability, but also for maintaining financial stability. Greater independence from external pressure implies that central banks are less politically constrained in acting to prevent financial distress, while it also will allow them to act earlier and more decisively when a crisis erupts. We estimate the relation between CBI and a newly constructed measure of financial instability using a dynamic panel model for the period 1985–2005 with a large set of control variables. We find a significant and robust negative relation between CBI and financial instability, which is mostly due to political independence.

Between 1996 and 2005 the number of central banks that publish a financial stability review (FSR) increased from 1 to 40. A FSR may contribute to financial stability, increase accountability of authorities responsible for financial stability, and strengthen co-operation between the various authorities. The occurrence of a banking crisis in the past, income per capita, and European Union membership increase the likelihood that a FSR is published. The content of FSRs differs widely; on average only 33% of the indicators as suggested by the IMF is actually published. The amount of information provided seems unrelated to the health of the banking system.

This paper provides a new indicator for central bank independence (CBI) based on the turnover rate of central bank governors for 82 developing countries over the period 1980–1989. Using this new indicator it is concluded that this proxy for CBI is related to inflation, only if the high inflation countries are included in the sample. The view that both CBI and inflation are caused by effective opposition towards inflation is not supported. Using both the extreme bound analysis and Sala-i-Martin's method we do not find evidence that CBI is robustly related to economic growth.

Over the last two decades, communication has become an increasingly important aspect of monetary policy. These real-world developments have spawned a huge new scholarly literature on central bank communication—mostly empirical, and almost all of it written in this decade. We survey this ever-growing literature. The evidence suggests that communication can be an important and powerful part of the central bank's toolkit since it has the ability to move financial markets, to enhance the predictability of monetary policy decisions, and potentially to help achieve central banks' macroeconomic objectives. However, the large variation in communication strategies across central banks suggests that a consensus has yet to emerge on what constitutes an optimal communication strategy.
