Liam Flynn is a partner in the Financial Institutions Group.  His practice focuses on advising financial institutions, especially banks and insurers, on strategically important matters both transactional and regulatory. 

He re-joined Matheson after serving for eight years as Deputy General Counsel of the Bank for International Settlements (BIS), the global centre of financial regulatory reform.  Prior to his BIS service he was a partner and Head of Corporate and Regulatory Insurance at Matheson between 2002 and 2010, where he maintained a wide-ranging practice leading the firm’s transactional representation of insurance-sector clients and was recognised as a leading practitioner by market directories.

From his BIS service, Liam has in-depth experience of the wide range of transactional, compliance and governance issues impacting internationally-active banks and financial institutions.  He led a team of lawyers at the BIS supporting its banking business and advised on institutional, board and C-suite issues.  He was active in strategic planning, legal risk management and identification, project execution, management of external counsel and preparation for significant corporate events.  His time at the BIS was an important period for post-crisis regulatory reforms, encompassing the finalisation of the Basel-III package, the introduction of G-SIFI designations and the development of resolution and recovery planning. 

At Matheson, Liam provides regulatory, governance and risk management advice, undertakes corporate and commercial transactional work and advises on internal and regulatory investigations.  He is an officer of the Banking Law Committee of the International Bar Association, a mediator accredited by CEDR UK and a Member of the Chartered Institute of Arbitrators.  He frequently speaks at global international financial services conferences.
