This paper studies banks' decision to form financial interconnections using a model of financial contagion that explicitly takes into account the crisis state of the world. This allows us to model the network formation decision as optimising behaviour of competitive banks, where they balance the...

We model a stylized banking system where banks are characterized by the amount of capital, cash reserves and their exposure to the interbank loan market as borrowers as well as lenders. A network of interbank lending is established that is used as a transmission mechanism for the failure of...

We analyze the reaction of stock returns and CDS spreads of banks from Europe and the United States to four major regulatory reforms in the aftermath of the subprime crisis, employing an event study analysis. In contrast to the public perception that nothing has happened, we find that financial...

We investigate the consequences of banks' liquidity hoarding behavior for the stability of the financial system proposing a new model of banking contagion through two channels, bilateral exposures and funding shortage. Inspired by the key role of liquidity hoarding in the 2007-2009 financial...

From the financial supervisor's point of view, an early warning system involves an ex ante approach to regulation, targeted to predict and prevent crises. An efficient EWS allows timely ex ante policy action and can reduce the need for ex post regulation. This chapter builds on existing...

This paper presents a methodology to examine the multivariate tail dependence of the implied volatility of equity options as an early warning indicator of systemic risk within the financial sector. Using non-parametric methods of estimating changes in the dependence structure in response to...

This paper empirically analyzes the determinants of banks' systemic importance. In constructing a measure on the systemic importance of financial institutions we find that size is a leading determinant. This confirms the usual "Too big to fail" argument. Nevertheless, banks with size above a...

This paper examines the potential for the U.S. insurance industry to cause systemic risk events that spill over to other segments of the economy. We examine primary indicators that determine whether institutions are systemically risky as well as contributing factors that exacerbate vulnerability...

CoVaR seeks to use joint return data to measure a firm's contribution to systemic risk. To learn what comprehensive regulatory changes can do to systemic risk in general, and CoVaR in particular, this paper uses difference-in-difference to estimate the impact of the extensive and coincident U.S....

We identify, measure and compare the characteristics of Global Systemically Important Banks (G-SIBs) vis-à-vis banks not chosen by the Financial Stability Board (FSB) to be in the 2011 G-SIB group; investors' responses to banks being classified as a G-SIB and how these responses relate to...
