Financial Law and Regulation

Convenor: Dr Giuliano G. Castellano

Dr Giuliano Castellano’s research and teaching interests are in the areas of regulatory governance, international financial law and compliance with focus on securities, banking and insurance regulation. He has published in renowned scholarly journals, such as the Modern Law Review, Law & Contemporary Problems, and Hastings Law Journal. He has been leading research projects that received support from competitive grant schemes in different jurisdictions, such as the British Economic and Social Research Council (ESRC) and the HK University Grants Committee. Beyond academia, Dr Castellano collaborates with international organisations and domestic policymakers to implement legal and regulatory reforms to support and inclusive and sound access to finance.

Financial law and regulation has been one of AIIFL’s core research areas since its establishment and remains one of its flagship areas of activity. Given Hong Kong’s position as one of the leading international financial centres, financial law and regulation are central areas of interest to researchers, professionals, policymakers, and students. This is reflected not only in the breadth of research theme covered by AIIFL Fellows, it is also apparent from the support that AIIFL provides to the Faculty of Law’s leading LLMs programmes, in Corporate and Financial Law and in Compliance and Regulation.

Since its establishment, AIIFL has striven to maintain its research activities at the cutting edge of issues relating to financial law and regulation in the domestic, regional, and global contexts. These have taken the form of a number of major research projects supported by competitive grants, internationally recognised publications, an ever-increasing list of events and activities as well as a constant engagement in relevant policy discourses both locally and internationally.

Major areas of research include:

  • Enhancing Hong Kong’s Future as a Leading International Financial Centre
  • FinTech and RegTech
  • Financial Crises and Systemic Risk
  • Legal and Regulatory Reforms for the Development of Credit, Capital, and Insurance Markets
  • Financial Liberalisation and Regulatory Reforms in China
  • The Political Economy of International Financial Regulation and Supervision
  • Recovery, Resolution, and Insolvency of Financial Institutions
  • Regulatory Compliance: Culture, Ethics and Business Conduct
  • Global Capital Markets
  • Sovereign Debt and Debt Restructuring
  • Securitisation, Derivatives and Structured Finance

In a fast-changing world where new socio-economic dynamics and unprecedented challenges are poised to disrupt the status quo, AIIFL will continue to promote innovative thinking to tackle major issues affecting the global financial system and its regulatory governance. AIIFL activities and research are disseminated through events, conducted virtually and/or in-person to ensure the broadest outreach and a lasting footprint.
