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 develops a model to analyse the optimal ex-ante capital and total loss absorbing capacity (TLAC) requirements, and the ex-post resolution policy of banks. Banks in our model are subject to two types of moral hazard: i) ex-ante, they have the incentive to shirk on project monitoring,...

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...

This paper compares the performance of regulatory thresholds as predictors of distress for large banks with their performance for small banks. Using a data set of capital and liquidity ratios for a sample of UK‑focused banks in 2007, we apply simple threshold-based rules to assess how...

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...

We examine how the repo market operates during liquidity stress by applying network analysis to novel transaction-level data of the overnight gilt repo market including the Covid-19 crisis. During this crisis, the repo network becomes more connected, with most institutions relying on existing...

We systematically analyse how network structure and bank characteristics affect solvency distress contagion risk in interbank networks. As interbank networks become more connected and more regular in structure, the contagion risk of system-wide shocks and individual bank defaults initially...

The credit risk that an individual bank poses to the rest of the financial system depends on its size, the type of exposures it has to the real economy, and its obligations to other institutions. This paper describes a system-wide risk management approach to calibrating individual banks' capital...

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 precipitated an increasing appreciation of the need for a systemic perspective towards financial stability. For example: What role do large banks play in systemic risk? How should capital adequacy standards recognize this role? How is stability shaped by...
