Position

John Ahern, partner at Katten Muchin Rosenman UK LLP and head of the London Financial Services group, focuses his practice on banking and financial services regulation with a strong focus on the UK and European financial markets and related regulations. His background in private practice and as in-house counsel at a global investment bank provides him with a perspective on the unique regulatory issues facing the wholesale and private banking sectors. John advises multilateral trading facilities, broker-dealers and banks on trading, clearing and settlement as well as client money and custody of securities—both physical and dematerialized. He has a particular focus on regulatory capital, and advises a number of banks and other authorized firms on the requirements and implications of the prudential regime. John counsels asset managers and investment advisors on the regulation of alternative funds in Europe.

John assists clients in navigating the regulatory system and counsels them in documenting a range of customer relationships, including the preparation of client agreements, inter-group arrangements, trading platform rulebooks and related compliance documentation.

John is a frequent speaker at seminars and conferences and has written a number of articles for well-respected publications on financial services regulations.
