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...

Asset quality is an essential part of sound banking. However, asset quality is difficult for banking regulators and investors to assess in the absence of a common, cross-border scheme to classify assets. Currently no standard is applied universally to classify loans, the most sizable asset on...

This paper uses regulator-provided transaction data to investigate how trading in dark pools affects intraday market quality on the limit order book of the primary exchange for members of the FTSE 100 index. Using trading patterns from execution algorithms as instrumental variables, I show that...

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 use transactional data from the USD and EUR segments of the plain vanilla interest rate swap market to assess the impact of the Dodd-Frank mandate that US persons must trade certain swap contracts on Swap Execution Facilities (SEFs). We find that, as a result of SEF trading, activity...

Using unique transactions data for individual high-frequency trading (HFT) firms in the UK equity market, we examine if the trading activity of individual HFT firms is contemporaneously and dynamically correlated with each other, and what impact this has on price efficiency. We find that HFT...

We use proprietary transactional data to examine the determinants of liquidity in the UK government bond (gilt) market, over a rich sample period that covers both the financial crisis of 2008–09 as well as the onset of the subsequent euro-zone sovereign debt crisis. During this period, gilt...

We show that larger trades incur lower trading costs in government bond markets ('size discount'), but costs increase in trade size after controlling for clients’ identities (‘size penalty’). The size discount is driven by the cross‑client variation of larger traders obtaining better...

Using supervisory data from UK central counterparties (CCPs), we study a collateral cycle in which market participants raise liquidity in the repo markets to meet CCPs margin calls, before CCPs reinvest the liquidity through reverse repos as well as bond purchases. In the first leg, we find that...
