We explore the impact of central clearing on the demand for collateral arising from variation margin calls in the derivatives market. We find that the aggregate demand for collateral is not necessarily minimal when all contracts are centrally cleared. Hence, at least in this respect, increasing...

We examine the role of macroeconomic fluctuations, asset market liquidity, and network structure in determining contagion and aggregate losses in a stylised financial system. Systemic instability is explored in a financial network comprising three distinct, but interconnected, sets of agents -...

An individual bank can put the whole banking system at risk if its losses in response to shocks push losses for the system as a whole above a critical threshold. We determine the contribution of banks to this systemic risk using a generalisation of the Shapley value; a concept originating in...

The global financial crisis has been the prompt for a complete rethink of financial stability and policies for achieving it. Over the course of the better part of a decade, a deep and wide-ranging international regulatory reform effort has been under way, as great as any since the Great...

How well equipped are today's macroprudential regimes to deal with a re-run of the factors that led to the global financial crisis? We argue that a large proportion of the fall in US GDP associated with the crisis can be explained by two factors: the fragility of financial sector — represented...

We use a proprietary database of individual UK capital requirements spanning 1989 to 2013 and panel regression techniques to evaluate whether the effects of capital requirements on banks' balance sheet adjustments changed after the 2008–09 financial crisis. We find that after the crisis banks...

We present the first study to estimate the causal effect of liquidity regulation on bank balance sheets. It takes advantage of the heterogeneous implementation of tighter liquidity regulation by the UK Financial Services Authority in 2010. We find that banks adjusted the composition of both...

While the financial crisis took a large toll on the UK banking industry overall, some institutions were forced to undertake more intensive efforts to deal with the economic downturn and onset of financial difficulties. This study examines whether and how the characteristics of these institutions...

We study solvency contagion risk in the UK banking system from 2008 to 2015. We develop a model that only accounts for losses transmitted after banks default, but also for losses due to the fact that creditors revalue their exposures when probabilities of default of their counterparties change....

This paper assesses the value of multiple requirements in bank regulation using a novel empirical rule‑based methodology. Exploiting a dataset of capital and liquidity ratios for a sample of global banks in 2005 and 2006, we apply simple threshold-based rules to assess how different...
