We assess the impact of contingent convertible (CoCo) bonds and the wealth transfers they imply conditional on conversion on the risk-taking behaviour of the issuing bank. We also test for regulatory arbitrage: do banks try to maintain risk-taking incentives by issuing CoCo bonds, when...

In this paper we construct and analyse the UK banking system’s Global Network of granular exposures which captures roughly 90% of the UK banking system’s total assets for the period 2018 Q1 to 2021 Q4. We thus study the microstructure of UK banking system focusing on the role played by...

How does bank profitability vary with interest rates? We present a model of a monopolistically competitive bank subject to repricing frictions, and test the model's predictions using a unique panel data set on UK banks. We find evidence that large banks retain a residual exposure to interest...

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 addresses the trade-off between additional loss-absorbing capacity and potentially higher bank risk-taking associated with the introduction of the Basel III leverage ratio. This is addressed in both a theoretical and empirical setting. Using a theoretical micro model, we show that a...

We exploit a unique dataset that features both un-intermediated mortgage requests and independent responses from multiple banks to each request. We show that households typically are not prudent risk managers, but prioritize minimizing current mortgage payments over insurance against future rate...

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...

This paper examines how banks' asset risk is affected by the level (i.e. group or business unit) at which regulatory requirements are applied. We develop a theoretical model and calibrate it to UK banks. Our main finding is that the impact differs depending on which regulatory constraint is...

Credit and interest rate risk in the banking book are the two most important risks faced by commercial banks. In this paper we derive a consistent and general framework to measure the integrated impact of both risks on banks' portfolios. The framework accounts for all sources of credit risk and...

Banks often measure credit and interest rate risk separately and then add the two risk measures to determine their overall economic capital. This approach misses complex interactions between the two risks. We develop a framework where credit and interest rate risks are analysed jointly. We focus...
