Dr David Murphy, Visiting Professor in Practice at LSE Law School and an expert in financial regulation, has a long term research project on the variability of margin. The tendency of margin requirements to increase when financial markets are stressed creates significant stress, and has been the focus of regulatory attention for some years since Dr Murphy's initial work in 2014.
