Over the last decade, banks around the world have been confronted with substantialmisconduct costs. We employ provisions for misconduct costs as an instrumentalvariable to identify the causal effect of a bank capital shock on risk-taking.Using new hand-collected data, we show that misconduct...

There is evidence that machine learning (ML) can improve the screening of risky borrowers, but the empirical literature gives diverse answers as to the impact of ML on credit markets. We provide a model in which traditional banks compete with fintech (innovative) banks that screen borrowers...

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...

The idea of separating retail and investment banking remains controversial. Exploiting the introduction of UK ring-fencing requirements in 2019, we document novel implications of such separation for credit and liquidity supply, competition, and risk-taking via a funding structure channel. By...

Macroprudential regulators worldwide have introduced regulations to limit household leverage in light of existing evidence which suggests that high leverage is associated with household distress during crisis. We analyse the distributional effects of such a macroprudential policy on mortgage and...

This paper examines the effects of competition on bank stability in the United Kingdom between 1994 and 2013. We construct several measures of competition and test the relationship between competition and bank stability. We find that, on average, competition lowers stability, but that its effect...

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,...

We study how banks' capital level affects the extent to which they engage in liquidity transformation. We first construct a simple model to develop testable hypotheses on this link. Then we test our predictions and establish the causality using a confidential Bank of England dataset that...

International standards for banking regulation leave individual countries with discretion to determine how the separate legal entities within a banking group should be brought together for the purposes of prudential regulation and supervision. This paper documents differences in the levels of...

Since Basel II was introduced in 2008, two approaches to calculating bank capital requirements have co-existed: lenders' internal models, and a less risk-sensitive standardised approach. Using a unique dataset covering 7 million UK mortgages for 2005–15, and novel identification, we provide...
