Financial Regulation

Our leading Financial Regulation practice supports clients from across the financial services spectrum including banks and lenders, insurers and reinsurers, investment firms, asset managers and funds, non-bank lenders, payment service providers, e-money issuers and financial market infrastructure businesses such as exchanges and clearing systems. We also advise those operating at the perimeter of the financial services sector.

Our projects frequently have an international or cross-border element. We work closely with leading financial regulatory experts in Europe, the US and Asia, who we believe have the best expertise and the right skill set to deliver what our clients need. We spend a proportion of our time in Brussels, to enhance our ability to monitor and advise on EU financial regulatory developments, as well as to engage with our network of financial regulatory contacts in European institutions.

Our Financial Regulation team forms part of the firm’s wider Financial Institutions Group to provide an integrated service across the entire waterfront of the financial sector.

We work closely with our Disputes and Investigations Group to handle regulatory investigations and disciplinary proceedings for major financial institutions.
