More widespread central clearing could enhance dealers’ ability to intermediate financial markets by increasing the netting of buy and sell trades, thereby reducing the impact of trading on balance sheets and capital ratios. Drawing on trade‑level regulatory data, we study the netting...

The banking reforms that followed the financial crisis of 2007–08 led to an increase in UK banking regulation from almost 400,000 to over 720,000 words, and to concerns about their complexity. We define complexity in terms of the difficulty of processing linguistic units, both in isolation and...

The interbank network, in which banks compete with each other to supply and demand differentiated financial products, fulfils an important function but may also result in risk propagation. We examine this trade-off by setting out a model in which banks form interbank network links endogenously,...

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...

As part of the post-crisis regulatory reform, many interest-rate derivative transactions are required to be centrally cleared. Nevertheless, the treatment of this type of transaction under the leverage ratio (LR) requirement does not allow for the use of initial margin to reduce the exposure,...

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...

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 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...

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...

This paper analyses how the risk-sharing capacity of the financial system varies over the business cycle, leading to procyclical fragility. We show how financial imperfections contribute to underinsurance by entrepreneurs, generating an externality that leads to the build-up of systematic risk...
