We present evidence of product market adjustments and asset reorganizations from the largest ever shift in risk regulation in a developed insurance market. Using proprietary data on insurance risk exposures from the Bank of England, we develop a measure of regulatory constraints that is...

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 develop a model of dealer intermediation in bond markets that takes account of how changing regulatory requirements for banks since the financial crisis, in particular, the introduction of minimum leverage ratio requirements, affect the cost and ability of dealer banks to provide...

We investigate the impact that the publication of the Bank of England's Financial Stability Report (FSR) has on the stock returns and credit default swap spreads of UK financial institutions. Examining a sample of 73 UK-listed banks and other financial institutions, we find that publication of...

Using unique data at transaction and counterparty identity level, we study the microstructure of the Swiss franc FX over‑the‑counter (OTC) derivatives market during a time of stress that was triggered by the decision of the Swiss National Bank (SNB) to remove the Swiss franc‑euro exchange...

Using a unique regulatory dataset with disclosed counterparty identities, we show that clients in corporate bond markets outperform when they trade with more dealers. The effect is stronger for informationally sensitive clients, assets, and during informationally intensive periods including...

Market participants have argued that a significant unintended consequence of post-crisis regulatory leverage ratio requirements has been a reduction in the liquidity of fixed income markets. We assess this claim in the context of the gilt (UK government bond) and gilt repo markets. We find that...

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...

This paper uses transaction data to estimate how single stock circuit breakers on the London Stock Exchange affect other stocks that remain in continuous trading. This ‘spillover' effect is estimated by calculating the effect of a trading halt on the market quality of stocks that remain in...

We propose a structural framework for the development of system-wide financial stress tests with multiple interacting contagion, amplification channels and heterogeneous financial institutions. This framework conceptualises financial systems through the lens of five building blocks: financial...
